The bank said no — or said yes with 30% down. You found the right business, negotiated the price, and now you need capital. The problem: your bank wants more equity than you have, or the seller will not carry a note, or the timeline does not work. This is where most acquisitions die — not because the deal is bad, but because the capital structure is wrong. The solution is not finding a different bank. It is structuring the complete capital stack so each layer plays its role: senior debt minimizes cost, the seller note fills the equity gap, mezzanine capital bridges what is left, and your equity injection meets program requirements without draining your reserves. This guide covers the complete capital stack framework for business acquisitions from $500K to $25M, with real deal structures, DSCR calculations at every tier, and the decision framework for when SBA does not fit.
1What Is a Capital Stack and Why Does It Matter for Acquisitions?
A capital stack is the layered structure of all capital sources used to fund a transaction. In business acquisitions, the stack typically includes four layers, ordered by seniority (who gets paid first in a default):
| Layer | Typical Source | Priority | Cost Range | Typical % of Stack |
|---|---|---|---|---|
| Senior Debt | SBA 7(a), bank term loan | 1st position | Prime + 2.25–3.0% | 60–80% |
| Seller Financing | Seller note (standby or non-standby) | 2nd position | 5–8% | 5–20% |
| Mezzanine / Sub Debt | Private credit, BDCs, mezzanine funds | 3rd position | 12–20% | 5–15% |
| Equity | Buyer cash, ROBS, investors | Last (residual) | Highest (ownership dilution) | 10–25% |
The reason this matters: most first-time buyers and even experienced operators treat acquisition financing as a single-source problem. They go to one bank, get one term sheet, and either accept it or walk away. That approach works when the bank offers 80% LTV with reasonable terms. It fails when the bank wants 30% down, the SBA cap does not cover the deal, or the timeline is too tight for government-backed lending.
The capital stack approach treats each layer as a purpose-built tool. Senior debt carries the majority of the load at the lowest cost. The seller note aligns incentives and fills the equity gap. Mezzanine debt bridges what the senior lender and seller cannot cover. Your equity injection is sized to meet program minimums — not a dollar more than necessary.
Key Principle
Every dollar you can finance at a reasonable cost is a dollar you keep in reserve for post-acquisition operations. Over-equitizing a deal feels safe, but it starves the business of working capital when you need it most — the first 12 months after close.
2Layer 1: SBA 7(a) as Senior Debt — The Foundation of Most Acquisition Stacks
The SBA 7(a) program is the single most popular financing vehicle for small business acquisitions in the United States. In 2025, the SBA authorized over $31 billion in 7(a) loans, and a significant percentage of those were acquisition-related. Here is why it sits at the base of most capital stacks — and where it breaks down.
SBA 7(a) Acquisition Parameters
| Parameter | Detail |
|---|---|
| Maximum Loan Amount | $5,000,000 |
| Interest Rate | Variable: Prime + 2.25% (loans over $250K, 10yr+ term) = 9.75% at current Prime of 7.50% |
| Repayment Term | 10 years for business acquisition (25 years if CRE included) |
| Down Payment | 10% minimum equity injection (can include seller note on standby) |
| SBA Guarantee | 75% on loans over $150K (85% under $150K) |
| Guarantee Fee | 2.0–3.5% of guaranteed portion (one-time, rolled into loan) |
| Prepayment Penalty | 5% year 1, 3% year 2, 1% year 3, none after (on loans with 15yr+ maturity) |
| Personal Guarantee | Required from all owners with 20%+ equity |
Pros of SBA 7(a) for Acquisitions
Lowest Cost of Capital Available
At Prime + 2.25–3.0%, SBA 7(a) offers the cheapest acquisition debt in the market. On a $3M loan over 10 years, the difference between SBA rates and private credit rates (12–15%) is $600K–$900K in total interest. That is not a rounding error — it is the difference between a profitable acquisition and a marginal one.
10% Down Payment (with Seller Note)
Most conventional acquisition lenders require 20–30% down. SBA requires 10% equity injection, and a portion of that can come from a seller note on full standby. This means a buyer can acquire a $2M business with as little as $100K–$200K in cash at close, depending on how the seller note is structured.
No Balloon Payments
SBA 7(a) loans are fully amortizing over the term. No balloon at year 5 or 7 like most conventional acquisition loans. This eliminates refinance risk — you are never forced to find new capital mid-stream.
Goodwill Financing
SBA is one of the only senior lending programs that will finance goodwill (the purchase price above tangible asset value). Most businesses sell at 2–4x EBITDA, which means 50–80% of the purchase price is goodwill. Conventional lenders typically will not lend against goodwill at all, or only to a limited extent.
Cons and Limitations
$5M Cap Is a Hard Ceiling
If your acquisition price is $6M and you need 80% financing, you need $4.8M — almost at the cap. If the price is $7M+, you are over the cap and need supplemental capital. The $5M limit also includes any guarantee fees rolled into the loan, working capital, and closing costs financed. A $5M purchase price often requires $5.3–5.5M in total loan proceeds, which exceeds the cap.
Timeline: 60–90 Days Minimum
SBA loans take time. The lender needs 30–45 days for their own underwriting, then submits to the SBA for guarantee approval (5–10 business days for standard processing). Environmental review, title work, collateral documentation, and closing add another 15–30 days. If your LOI has a 45-day close window, SBA probably will not make it.
Variable Rate Exposure
All SBA 7(a) acquisition loans are variable rate, tied to the WSJ Prime Rate. If Prime moves from 7.50% to 9.50% over the life of the loan (which it did between 2022 and 2023), your debt service increases proportionally. On a $3M loan, a 200bps Prime increase adds approximately $60K per year in interest expense. There is no fixed-rate option for 7(a) business acquisition loans.
Full Personal Guarantee
Every owner with 20%+ equity signs an unlimited personal guarantee. This means your personal assets (house, savings, investments) are at risk if the business fails and the loan defaults. The SBA guarantee protects the lender, not you. This is a meaningful consideration for buyers with significant personal wealth.
3Layer 2: Seller Financing — The Most Misunderstood Layer in the Stack
Approximately 80% of SBA-backed business acquisitions include some form of seller financing. It is not optional — it is structural. The seller note fills the gap between what the SBA lender will fund and what the buyer can inject as equity. But the rules around seller notes in SBA transactions are specific, and getting them wrong can kill the deal.
SBA Standby Rules for Seller Notes
When a seller note is used alongside an SBA 7(a) loan, the SBA classifies it as either "full standby" or "partial standby," which determines when the seller gets paid.
| Standby Type | Payments During Standby | Duration | When Used | Counts as Equity? |
|---|---|---|---|---|
| Full Standby | No payments (principal or interest) for standby period | Typically 24 months (some lenders require 30 months) | When seller note counts toward 10% equity injection | Yes |
| Partial Standby | Interest-only payments allowed during standby | Same as SBA loan term or negotiated period | When seller note does NOT count as equity | No |
| Non-Standby | Full P&I payments from day one | N/A | When used outside SBA structure (conventional deals) | N/A |
Critical Rule
If the seller note is on full standby and counts as part of the buyer's equity injection, the note must be subordinate to the SBA loan, cannot have any payments during the standby period, and the term must be at least as long as the SBA loan term. If these conditions are not met, the SBA will not count the seller note as equity — and your deal may fail the 10% equity injection test.
Typical Seller Note Terms
Standard Terms
- • Interest rate: 5–8% (negotiated)
- • Term: 5–7 years (must match or exceed SBA term if standby)
- • Amortization: Fully amortizing or interest-only with balloon
- • Security: Subordinate lien on business assets
- • Typical size: 5–20% of purchase price
Negotiation Leverage Points
- • Rate: tied to deal risk and seller motivation
- • Standby period: longer benefits buyer cash flow
- • Earnout component: tie portion to performance targets
- • Conversion clause: convert to equity under certain triggers
- • Offset rights: deduct against seller reps and warranties
Why Sellers Agree to Carry Notes
From the seller's perspective, a seller note is not just financing — it serves three purposes. First, it enables the transaction: if the buyer cannot close without the note, the seller either carries the note or loses the deal. Second, it provides tax advantages: installment sales allow the seller to spread capital gains over the note term rather than recognizing the full gain at close. Third, it generates above-market returns: a 6–8% note secured by the business the seller knows intimately is a better risk-adjusted return than most fixed-income alternatives.
The counterargument sellers raise is concentration risk — their entire net worth is now concentrated in one business they no longer control. This is a legitimate concern, and it is why seller notes rarely exceed 20% of the purchase price. The sweet spot in most deals is 10–15% on a seller note with a 24-month full standby, providing the buyer breathing room while giving the seller a reasonable timeline to full payout.
4Layer 3: Mezzanine and Subordinated Debt — Bridging the Gap
Mezzanine debt sits between the senior loan and equity in the capital stack. It is junior to the bank loan but senior to equity, and it carries a higher interest rate to compensate for the increased risk. In acquisition financing, mezzanine capital serves one primary purpose: filling the gap that the senior lender and seller note cannot cover.
When Mezzanine Capital Is Necessary
The SBA Cap Gap
Deal price is $8M. SBA caps at $5M. The seller will carry 10% ($800K). Buyer has $500K in equity. That leaves a $1.7M gap. Mezzanine fills it. Without mezzanine, the buyer needs $2.2M in cash — which most individual buyers do not have for a deal of this size.
Seller Refuses to Carry
Some sellers demand all cash at close. The SBA lender will fund 75–80% of the deal, but the buyer needs the remaining 20–25% in cash or subordinated debt. If the buyer only has 10–15% in cash, a mezzanine lender bridges the remaining 5–15%.
Post-Acquisition Working Capital
The buyer can close the deal with available capital, but doing so drains every dollar of reserves. A mezzanine tranche of $300K–$500K allows the buyer to retain working capital for the first 12 months of ownership — the period when unexpected expenses are most likely.
Speed — When SBA Will Not Close in Time
Private credit mezzanine can close in 2–4 weeks. If the deal has a 30-day close window and the seller will not extend, a mezzanine-heavy stack (70% private credit senior + 15% mezzanine + 15% equity) can close on time. The plan is to refinance into SBA within 6–12 months when timing is no longer a constraint.
Mezzanine Debt Terms for Acquisitions
| Parameter | Typical Range | Notes |
|---|---|---|
| Interest Rate | 12–20% | Cash pay + PIK component common |
| Term | 3–7 years | Often interest-only for 12–24 months |
| Equity Kicker | 5–15% of equity | Warrants or direct equity participation common on larger deals |
| Minimum Deal Size | $500K–$2M | Most institutional mezzanine funds start at $2M+ |
| Collateral | 2nd lien or unsecured | Subordinate to senior lender; may require intercreditor agreement |
| Prepayment | Call protection 1–3 years | 101–103% of par during call period, then par |
Important: SBA and Mezzanine Do Not Mix Easily
The SBA has strict rules about subordinated debt in the capital stack. Mezzanine debt that is not on standby is treated as a liability that reduces the borrower's debt service coverage ratio (DSCR). If the mezzanine payment pushes DSCR below 1.15x, the SBA deal fails. The workaround: structure the mezzanine as a standby note (no payments during the SBA loan term) or close the SBA and mezzanine sequentially — SBA first, then layer mezzanine on top with the senior lender's consent. Both approaches require coordination between the senior lender and the mezzanine provider, which is why having a single advisor managing both relationships matters.
Sources of Mezzanine Capital
For Deals Under $5M
- • Search fund mezzanine lenders
- • SBA-adjacent mezzanine providers
- • Family offices focused on lower middle market
- • SBICs (Small Business Investment Companies)
- • Independent sponsors with co-invest capital
For Deals $5M–$25M
- • BDCs (Business Development Companies)
- • Institutional mezzanine funds
- • Private credit funds with mezz strategies
- • Insurance company private placements
- • CDFIs for underserved market deals
5Layer 4: Equity Injection — How Much Do You Actually Need?
Equity injection requirements vary by deal size, program type, and lender risk appetite. The table below shows typical equity requirements across common acquisition scenarios.
| Deal Size | Primary Financing | Minimum Equity % | Cash Required | Notes |
|---|---|---|---|---|
| $500K | SBA 7(a) | 10% | $50K | Seller note on standby can satisfy part of injection |
| $2M | SBA 7(a) | 10% | $100K–$200K | $100K if seller note covers remainder of injection |
| $5M | SBA 7(a) at cap | 10–15% | $250K–$500K | At $5M cap, guarantee fees push total above limit |
| $10M | Conventional / private credit | 20–30% | $2M–$3M | SBA maxed; conventional requires more equity |
| $25M | Private credit + mezzanine | 20–35% | $5M–$8.75M | Institutional underwriting; may include rollover equity from management |
Sources of Equity Injection
Personal Cash and Savings
The most straightforward source. Lenders want to see the buyer has "skin in the game." For SBA deals, cash must be verified and seasoned — meaning it has been in your account for at least 60–90 days. A sudden $200K deposit from an unknown source will trigger questions and potentially delay closing.
ROBS (Rollover for Business Startups)
You can use 401(k) or IRA funds to capitalize a new C-Corp that acquires the target business — without triggering early withdrawal penalties or taxes. ROBS is legal, IRS-approved, and commonly used in SBA acquisitions. The catch: it requires a C-Corp structure, ongoing compliance, and a ROBS administrator. Typical cost: $5K setup + $150/month. PeerSense works with ROBS providers and can coordinate this alongside your lending process.
Home Equity (HELOC or Cash-Out Refi)
A HELOC on your primary residence provides liquid cash for the equity injection. SBA lenders accept this as a legitimate equity source, but the HELOC payment counts as a personal obligation in your debt-to-income ratio. If the HELOC payment plus your new business debt service ratio exceeds comfortable levels, it may reduce the amount the SBA lender will approve.
Investor Equity (Partners or Search Fund)
For larger deals ($5M+), equity often comes from investors — either a single partner or a search fund structure with multiple LPs. The key SBA consideration: any investor with 20%+ ownership must personally guarantee the SBA loan and pass the character check. This limits the number of investors who will participate in SBA-backed deals. For non-SBA deals, investor equity can be structured with preferred returns, liquidation preferences, and governance rights.
6DSCR Calculations at Every Tier of the Capital Stack
Debt Service Coverage Ratio (DSCR) is the single most important metric in acquisition underwriting. It measures whether the business generates enough cash flow to cover its debt payments. The formula is simple. The application is not.
DSCR = Adjusted EBITDA / Total Annual Debt Service
Where Adjusted EBITDA = Net Income + Interest + Taxes + Depreciation + Amortization + Owner Compensation Adjustments + One-Time Add-Backs
DSCR Minimums by Lender Type
| Lender Type | Minimum DSCR | Comfortable DSCR | Notes |
|---|---|---|---|
| SBA 7(a) | 1.15x | 1.25x+ | Many PLP lenders use 1.25x as their internal minimum |
| Conventional Bank | 1.25x | 1.35x+ | Banks want more cushion without the SBA guarantee |
| Private Credit (Senior) | 1.20x | 1.30x+ | Higher rate means higher debt service, so absolute DSCR may be lower |
| Mezzanine (All-In) | 1.05x | 1.10x+ | DSCR calculated on total stack (senior + mezz + seller note payments) |
DSCR Worked Example: $2M Acquisition
Business: HVAC company, adjusted EBITDA $450K, purchase price $2M (4.4x multiple)
| Capital Layer | Amount | Rate | Term | Annual Debt Service |
|---|---|---|---|---|
| SBA 7(a) | $1,600,000 | 9.75% (P+2.25) | 10 years | $209,000 |
| Seller Note (standby yr 1-2) | $200,000 | 6% | 7 years | $0 (standby) |
| Buyer Equity | $200,000 | — | — | — |
| Total | $2,000,000 | — | — | $209,000 |
Year 1 DSCR (standby period): $450,000 / $209,000 = 2.15x ✔
After standby, seller note adds ~$34K/year in debt service
Year 3 DSCR (all payments active): $450,000 / $243,000 = 1.85x ✔
Warning: DSCR Traps
Lenders calculate DSCR using their own adjusted EBITDA — which may differ from the broker's presentation. Common adjustments that reduce EBITDA: replacing owner salary with market-rate manager compensation, removing one-time revenue (PPP, EIDL forgiveness, asset sales), and normalizing above-market rent if the seller owns the real estate. Always model DSCR using the lender's adjustments, not the seller's pro forma.
7When SBA Does Not Fit — And What Replaces It
SBA 7(a) is the default for deals under $5M, but it does not work for every acquisition. Here are the scenarios where SBA fails and the capital sources that replace it.
Deal Exceeds $5M
Problem: Purchase price is $8M–$25M+. SBA maxes at $5M in loan proceeds.
Solution: Conventional bank acquisition financing (20–25% down, 5–7 year term with balloon), private credit senior debt (15–18%, flexible structures, fast close), or a combination — SBA at $5M for the senior tranche plus private credit mezzanine for the gap.
Timeline Under 45 Days
Problem: Seller demands close in 30–45 days. SBA processing takes 60–90 days minimum.
Solution: Private credit bridge loan to close the deal, with a planned SBA refinance within 6–12 months. The bridge costs more (12–18%) but provides certainty of close. The SBA refinance replaces the expensive debt with 10-year amortizing debt at Prime + 2.25%. Total cost of the two-step process is higher than direct SBA, but the deal closes.
DSCR Below 1.15x
Problem: The business does not generate enough cash flow to cover SBA debt service at the proposed purchase price.
Solution: Three options. First, renegotiate the purchase price down until DSCR clears 1.25x. Second, restructure the stack — increase the seller note (which can be on standby and excluded from DSCR calculations) and decrease the SBA portion. Third, use private credit with interest-only periods that reduce debt service in years 1–2 while the buyer implements operational improvements to grow EBITDA.
Industry Exclusion
Problem: Target business is in an SBA-excluded industry (cannabis, gambling, speculative real estate, lending).
Solution: Private credit is industry-agnostic. Cannabis-focused lenders exist. Specialty finance companies serve gambling and gaming. The rates are higher (14–24%), but capital is available for profitable businesses regardless of NAICS code.
Buyer Does Not Meet SBA Requirements
Problem: Credit score below 680, prior bankruptcy, insufficient industry experience, or immigration status that does not qualify.
Solution: Conventional lenders and private credit funds underwrite the deal economics, not the SBA checklist. A buyer with a 650 credit score but 15 years of industry experience and a strong business plan can get funded through non-SBA channels. The rate reflects the risk, but the capital is available.
8Real Deal Structures: Four Tiers from $500K to $25M
Below are four real-world capital stack structures at different deal sizes. These are representative of actual deals PeerSense has structured — specific details anonymized.
Tier 1: $500K — Residential Cleaning Franchise Acquisition
Single-unit franchise, $150K adjusted EBITDA, 3.3x multiple
| Layer | Source | Amount | % of Stack | Rate | Annual DS |
|---|---|---|---|---|---|
| Senior | SBA 7(a) | $400,000 | 80% | 9.75% | $52,200 |
| Seller Note | Full standby (24 mo) | $50,000 | 10% | 6% | $0 (yr 1-2) |
| Equity | Buyer cash | $50,000 | 10% | — | — |
DSCR Year 1: $150K / $52.2K = 2.87x | Cash at Close: $50K + ~$8K closing costs = $58K
Clean SBA deal. No mezzanine needed. Seller note on full standby counts toward equity injection. Buyer retains working capital reserves.
Tier 2: $2M — HVAC Services Company Acquisition
Established HVAC company, $450K adjusted EBITDA, 4.4x multiple, 15 employees
| Layer | Source | Amount | % of Stack | Rate | Annual DS |
|---|---|---|---|---|---|
| Senior | SBA 7(a) | $1,600,000 | 80% | 9.75% | $209,000 |
| Seller Note | Full standby (24 mo) | $200,000 | 10% | 6% | $0 (yr 1-2) |
| Equity | Buyer cash + ROBS | $200,000 | 10% | — | — |
DSCR Year 1: $450K / $209K = 2.15x | Year 3 (all payments): $450K / $243K = 1.85x
Cash at Close: $100K cash + $100K ROBS (401k rollover) + ~$20K closing costs = $120K out of pocket
ROBS allows the buyer to use retirement funds as equity without tax penalty. The 2.15x DSCR gives the SBA lender plenty of comfort. After the standby period, total debt service is still well within coverage.
Tier 3: $10M — Regional Manufacturing Company
Precision machining, $2.2M adjusted EBITDA, 4.5x multiple, includes $3M in equipment and $1.5M in real estate
| Layer | Source | Amount | % of Stack | Rate | Annual DS |
|---|---|---|---|---|---|
| Senior (A) | SBA 7(a) — business assets | $5,000,000 | 50% | 9.75% | $653,000 |
| Senior (B) | SBA 504 — real estate | $1,350,000 | 13.5% | ~6.5% fixed | $104,000 |
| Mezzanine | Private credit fund | $1,150,000 | 11.5% | 14% (IO yr 1) | $161,000 |
| Seller Note | Partial standby (IO yr 1-2) | $1,000,000 | 10% | 7% | $70,000 (IO) |
| Equity | Buyer + partner | $1,500,000 | 15% | — | — |
Year 1 DSCR (SBA only): $2.2M / $757K = 2.91x | All-In DSCR: $2.2M / $988K = 2.23x
Cash at Close: $1.5M equity (buyer: $800K, partner: $700K) + ~$120K closing costs = $1.62M
This is a four-layer stack. The SBA 7(a) covers the business acquisition up to the $5M cap. The SBA 504 finances the real estate at a fixed rate with a 20-25 year term. Mezzanine fills the gap. Seller carries $1M on partial standby (interest-only for 24 months). The buyer and a partner split the equity injection. All-in DSCR at 2.23x is strong — the business can comfortably service all four layers.
Tier 4: $25M — Multi-Location Services Platform
Regional services platform (20 locations), $5.5M adjusted EBITDA, 4.5x multiple, management rollover
| Layer | Source | Amount | % of Stack | Rate | Annual DS |
|---|---|---|---|---|---|
| Senior | Private credit (unitranche) | $15,000,000 | 60% | SOFR + 550 (~10.8%) | $2,430,000 |
| Mezzanine | BDC mezzanine fund | $3,750,000 | 15% | 15% (10% cash + 5% PIK) | $375,000 cash |
| Seller / Rollover | Management rollover equity | $1,250,000 | 5% | Equity (15-20% of NewCo) | — |
| Equity | Buyer + investor group | $5,000,000 | 20% | — | — |
Senior DSCR: $5.5M / $2.43M = 2.26x | All-In DSCR (cash pay): $5.5M / $2.805M = 1.96x
Cash at Close: $5M equity from buyer and investors + ~$400K transaction costs = $5.4M
At $25M, SBA is irrelevant — the structure is fully institutional. The unitranche (combined senior and stretch) from a private credit fund provides 60% of the stack at a blended rate. BDC mezzanine adds leverage with a PIK component (interest that accrues rather than paying cash, preserving cash flow). Management rolls over 5% of the deal as equity, aligning incentives. The buyer group invests $5M for majority ownership and control.
9How PeerSense Structures the Capital Stack
Capital stack structuring is not a one-and-done exercise. It is an iterative process that starts with the deal economics, maps to available capital sources, and adjusts based on real term sheets from real lenders. Here is how PeerSense approaches it.
Deal Analysis and Stack Mapping
We start with the deal — purchase price, adjusted EBITDA, industry, asset composition, timeline, and buyer profile. From there, we map every viable capital source: SBA 7(a), SBA 504 (if real estate is involved), conventional bank, private credit senior, mezzanine, and seller financing. We model the DSCR at every combination to find the stack that minimizes cost while maintaining adequate coverage ratios.
Parallel Market Process
For most deals, we run SBA and private credit processes simultaneously. The SBA track goes to 2-3 qualified lenders from our network of 899+ SBA lenders. The private credit track goes to 2-5 funds from our institutional capital relationships. Running both tracks in parallel means you have term sheets from both markets within 2-3 weeks — and you can compare cost, speed, flexibility, and certainty of close side by side.
Seller Note Negotiation Support
We help structure the seller note to align with SBA standby requirements and maximize its contribution to the capital stack. This includes advising on standby terms, interest rates, term length, and how to position the seller note in negotiations so the seller sees the benefit (tax deferral, above-market return) rather than just the risk (delayed payment).
Mezzanine Sourcing (When Needed)
For deals where the gap exceeds what the seller note and buyer equity can cover, we source mezzanine capital from our network of private credit funds, SBICs, BDCs, and family offices. We coordinate the intercreditor agreement between the senior lender and mezzanine provider — the document that governs their respective rights, which is often the most complex part of a multi-layer stack.
Close and Post-Close Optimization
We manage the closing timeline across all capital sources — coordinating SBA authorization, private credit commitment letters, seller note documentation, and closing conditions. Post-close, we advise on refinance timing: when to take out the bridge loan with permanent SBA financing, when to prepay the mezzanine tranche, and when to restructure the seller note as the business performs.
No Retainers. Referral Fee at Closing.
We do not charge upfront fees. Our referral fee is established before we start work and is paid at closing — meaning our incentive is aligned with yours: close the deal at the best possible terms.
Tell Us About Your Acquisition10Decision Framework: Choosing the Right Capital Stack for Your Deal
The right capital stack depends on five variables. Use this framework to determine which structure fits your deal before you start the process.
| Variable | SBA-Led Stack | Conventional Bank | Private Credit-Led Stack |
|---|---|---|---|
| Deal Size | Under $5M | $2M–$15M | $3M–$100M+ |
| Timeline | 60–90 days | 45–75 days | 21–45 days |
| Equity Required | 10% | 20–30% | 15–35% |
| Rate Range | Prime + 2.25–3.0% | SOFR + 250–400 | SOFR + 500–800 |
| Amortization | 10yr fully amortizing | 5–7yr balloon | IO periods available |
| Personal Guarantee | Full (20%+ owners) | Full or limited | Limited or none on larger deals |
| Best For | First-time buyers, sub-$5M deals, minimize cash at close | Experienced operators, strong banking relationships, CRE-heavy deals | Speed, flexibility, above-$5M, complex structures, limited PG |
The Best Answer Is Usually "Both"
Run the SBA process and the private credit process in parallel. Compare real term sheets. Choose the best combination for your specific deal. The 3-4 weeks it takes to get competing term sheets saves months of regret from choosing the wrong structure.
11Common Mistakes That Kill Acquisition Capital Stacks
Over-Paying Because "The Bank Will Fund It"
The fact that a bank will fund the deal at 3.5x EBITDA does not mean 3.5x is the right price. DSCR at 3.5x might be comfortable, but the buyer is paying for three and a half years of future earnings before they operate the business for a single day. Always model the post-acquisition cash flow — not just whether the debt service is coverable, but whether the buyer earns an adequate return on their equity after debt service, taxes, and a market-rate salary.
Ignoring the Standby Period Cash Flow Impact
During the 24-month seller note standby, the buyer's cash flow looks excellent — because they are only paying the SBA loan. Year 3 is the danger zone: the seller note payments kick in, and total debt service jumps 15–25%. If the buyer has not grown EBITDA or reduced costs during the standby period, year 3 can create a cash flow crisis. Always model the post-standby debt service scenario before closing.
Working With an Advisor Who Only Knows One Market
If your broker only knows SBA, every deal looks like an SBA deal — even when private credit is faster, more flexible, or structurally better. If they only know private credit, you will never see what the bank market would have offered. The advisor's market access determines your options. PeerSense accesses both markets because the optimal capital stack for most deals involves sources from both.
Draining Reserves to Minimize Debt
Some buyers put 30% down when 10% would suffice because they "want less debt." The problem: the first year of ownership always costs more than projected. Equipment breaks, key employees leave, customers churn during the transition. Having $200K in reserve versus $0 is the difference between navigating the transition and scrambling for an emergency line of credit at the worst possible time.
The Bottom Line
Business acquisition financing is not about finding one lender who will fund the entire deal. It is about structuring the complete capital stack so each layer plays its role. SBA 7(a) provides the senior debt at the lowest cost. The seller note fills the equity gap and aligns incentives. Mezzanine or private credit bridges the difference when the senior lender and seller cannot cover the full purchase price. Your equity injection is sized to meet program minimums — not drain your reserves. The capital stack approach works because it treats each dollar of financing as a tool with a specific purpose, cost, and priority. The deals that close efficiently are the ones where every layer is structured before the LOI is signed, not cobbled together after the bank says no. If you are acquiring a business between $500K and $25M, the capital stack framework in this guide gives you the structure. PeerSense gives you the access — 500+ capital sources, both SBA and private credit, with no retainers and a referral fee at closing.
