How to Raise Money to Buy a Business: Capital Stack Guide
How to Raise Money to Buy a Business: Capital Stack Guide

Only approximately 58% of search funds acquired a business in the aggregate cohort tracked since 1996 by Stanford's search-fund research. That isn't a forecast for your acquisition, but it reframes the challenge: finding a company and assembling executable financing are different jobs.
Learning how to raise money to buy a business starts with calculating the cash you'll need, not writing an investor pitch. You need enough funding to pay the seller, complete diligence, satisfy lender conditions, and keep operating after ownership changes. Then you need to sequence commitments so investors aren't underwriting a financing structure the bank or seller hasn't accepted.

How Much Cash a Business Purchase Really Needs
The listing price is what the seller wants for the business. Your total funding requirement also includes the costs of getting control and keeping the company solvent afterward.
Build the model around this equation:
Total uses = purchase consideration + transaction costs + incremental working capital + required refinancing and reserves + operating cushion.
Keep purchase consideration separate from survivability capital. The seller receives the former. You retain the latter to meet obligations while receivables arrive, customers adjust to the transition, and you learn how the business operates.
Build a complete sources-and-uses schedule
Use a spreadsheet with separate tabs for uses, funding sources, operating cash flow, and sensitivities. Every use needs an amount supported by a document, calculation, or explicit assumption, not a plug that makes the financing balance.
| Use of funds | Typical financing | Watch for |
|---|---|---|
| Purchase price | Senior debt, seller note, buyer equity | Use the consideration defined in the letter of intent, including closing adjustments |
| Transaction fees, including legal, quality of earnings, and any buyer-paid broker fees | Buyer equity or an eligible financed expense | Obtain engagement estimates and identify who owes each fee |
| Working capital reserve | Revolving line or equity | Calculate the gap between payroll, supplier payments, and customer collections |
| Debt refinancing or lender reserves | Senior debt or separate facility | Confirm payoff statements and the lender's written reserve requirements |
| Operating cushion | Equity or approved subordinated capital | Size against stressed cash requirements, not just scheduled loan payments |
| Total uses | Sum of confirmed sources | Include only funding available when the expense falls due |
Don't count existing debt twice. If the seller must repay it from the purchase proceeds, adding it again as a buyer use inflates the raise. Likewise, establish whether normal working capital transfers with the business before adding a separate reserve.
The distinction between acquisition funding and operating funding matters. The Federal Reserve's employer-firm survey reported that 56% of financing-seeking firms sought financing for operating expenses.
Match each expense to eligible funding
Ask the senior lender which acquisition costs, refinancing obligations, and working-capital needs it will finance. Don't assume its approved loan amount can pay every line in your spreadsheet.
A seller note defers purchase consideration; it doesn't put cash into the operating account right away. Rollover equity similarly reduces the seller's cash-out requirement without necessarily funding payroll. A working-capital facility can address collections timing, but its borrowing conditions must match the assets you'll have.
Practical rule: Money available to pay the seller isn't the same as money available to survive the transition.
If you're a first-time operator without comparable operating experience, allow more room for uncertainty rather than assuming you can manage the business's tightest historical cash position immediately.
Before making an offer, list every use, identify its supporting evidence, attach an eligible source, and size the retained reserve. The resulting total, not the listing price, is the amount your financing plan must cover.
Pick a Capital Stack That Fits Your Deal
Build around several compatible sources rather than one hoped-for loan. Survey results for ordinary business financing do not translate into acquisition-loan approval probabilities; an applicant can be offered less than requested or declined when cash flow, collateral, guarantees, or eligible uses do not fit the credit box. Treat any single approval as helpful evidence, never as the plan.
The sequence matters as much as the mix. Price the whole cash need first, including purchase consideration, transaction costs, working capital and a post-close reserve, then make commitments only after the senior lender and seller confirm the terms each layer depends on.
Compare funding by its job in the transaction
There isn't a defensible universal percentage for each layer. Size debt to repayment capacity and lender conditions, then negotiate seller participation and calculate the equity requirement.
| Source | How the share is set | Cost and terms | Main constraint |
|---|---|---|---|
| SBA acquisition loan under the 7(a) program | Determined by current program requirements and lender underwriting | Confirm interest, fees, amortization, guarantees, and eligible uses in writing | Borrower eligibility, equity requirements, and repayment capacity |
| Conventional bank term loan | Set by lender underwriting | Compare rate, repayment schedule, security, covenants, and prepayment terms | Cash flow, collateral, and lender appetite |
| Subordinated seller note | Negotiated portion accepted by the senior lender | Interest, maturity, payment schedule, and possible standby | Senior-lender approval and seller willingness |
| Mezzanine or subordinated debt | Sized to the negotiated structure | Additional interest burden, potentially with equity participation | Whether residual cash flow supports another claim |
| Buyer or partner equity | Remaining funding requirement | Ownership, distributions, and governance rights | Buyer liquidity and acceptable dilution |
| Rollover or joint venture equity | Negotiated ownership contribution | Returns tied to the equity agreement | Valuation, control, and exit alignment |
| Asset-based or working-capital line | Sized to eligible receivables and inventory | Revolving borrowing with borrowing-base conditions | Availability changes as eligible assets change |
The cheapest-looking source can produce the most restrictive structure. A lower interest rate doesn't compensate for an amortization schedule that consumes operating cash. Equity avoids scheduled principal repayment, yet it can cost control, distributions and a share of exit proceeds.
Use a comparison of equity and debt financing for acquisitions to separate repayment obligations from ownership costs before comparing proposals.
Establish sizing before negotiating the residual
Start with senior debt because its conditions influence the other layers. Obtain an indicative amount, repayment schedule, security package and position on seller debt. Then determine whether a seller note can fill an acceptable part of the purchase consideration without breaching the senior lender's subordination limits.
Run the stack as a sources-and-uses check. Uses cover purchase price, fees and post-close liquidity. Sources count only capital with written terms: confirmed senior debt, permitted seller financing, other documented facilities and equity. If a source can shrink because receivables age, standby terms change or a lender trims eligibility, it does not belong in the committed column yet.
Calculate equity last:
Required equity = total uses − available senior debt − permitted seller financing − other confirmed funding.
“Available” matters. An undrawn revolving facility subject to ineligible receivables isn't equivalent to closing cash. Neither is seller rollover that reduces cash consideration but leaves transaction expenses unpaid.
- Keep another lender category open. A credit union or asset-based lender may evaluate a different aspect of the business than your initial bank.
- Match financing to the asset. Receivables financing should support collectible receivables, not permanent losses or an unsupported purchase premium.
- Limit structural complexity. Ask the senior lender to approve proposed subordinate layers before negotiating them as settled terms.
- Compare total obligations. Model all scheduled payments together, including seller debt once any standby ends.
Your objective isn't maximum borrowing. It's a stack the company can service without forcing you to return to investors immediately after closing.
Start Capital Readiness Before You Make an Offer
Sellers want evidence that you can close. Investors want to know what they're buying. Asking investors for binding acquisition capital before identifying a target doesn't resolve that tension; it shifts undefined risk onto them.
Yale's study of what business sellers seek in a buyer describes sellers seeking evidence of execution capacity, including contact with expected investors or bank-statement evidence. It also recognizes that uncommitted searchers can arrange financing suited to a particular company.
The answer is progressive capital readiness. Show evidence appropriate to the stage without describing interest as committed funding.
Climb the capital-readiness ladder
| Rung | What you prove | Who you approach | Commitment level |
|---|---|---|---|
| Personal liquidity | Documented funds available for acquisition and diligence | Your financial institutions and advisers | Your own available funds |
| Investor soft circle | Interest in a defined acquisition profile | Angels, family offices, operating partners | Non-binding |
| Lender prequalification | Indicative borrowing capacity and eligibility | Small banks and acquisition lenders | Preliminary indication |
| Transaction-specific documents | A live target, investment memo, and sized stack | Interested investors and lenders | Conditional on stated approvals |
| Final commitment | Executed funding documents and identified closing conditions | Selected lender and investors | Binding according to the documents, subject to conditions |
Keep personal emergency savings distinct from acquisition liquidity. A bank statement can prove that money exists, but your model must show how much you're prepared to invest.
For investors, define the target industry, geography, operating role, cash-flow characteristics, and valuation discipline. Ask whether that profile fits their mandate and what information they'd need to evaluate a live opportunity.
Describe capital by its actual status: available, indicated, conditional, or committed. Don't collapse those categories into “funded.”
Send outreach that exposes the unknowns
A useful initial message is specific without pretending diligence is complete:
I'm evaluating an established business in my target industry and plan to operate it directly. I can document my proposed equity contribution, and my preliminary model shows debt capacity based on historical cash flow. I'm seeking an indicative financing discussion before submitting an offer, with diligence and funding milestones to be agreed. Customer concentration remains unverified, so the current sizing is conditional.
For an investor, add the expected equity role and governance discussion. For a lender, attach the financial summary and ask what information could materially change its sizing.
Avoid these early mistakes:
- Treating a pitch as a financing plan. Interest doesn't establish amount, timing, or terms.
- Requesting final commitments too early. A target profile isn't a transaction-specific underwriting package.
- Submitting an unsized offer. Seller credibility suffers when you discover the equity gap only after exclusivity begins.
Finish the preliminary sources-and-uses model, seek independent lender indications, and test investor interest before submitting the letter of intent. Preserve financing and diligence conditions with legal advice rather than promising certainty you haven't earned.
Build Pitch Materials That Pass Underwriting
A compelling acquisition thesis explains why you want the company. An underwriting package explains how the company will repay lenders and generate investor returns.
Organize a secure document room with consistent file names, a document index, and a model whose inputs reconcile to the underlying records. Don't send a polished presentation with financial statements that contradict it.
Put verifiable records ahead of projections
Prepare the package in this order:
- Historical financial statements and tax returns. Include available annual records, current interim statements, and reconciliations for material differences.
- Normalized earnings bridge. Start with reported results and document each adjustment to earnings before interest, taxes, depreciation, and amortization, or EBITDA.
- Debt and obligation schedule. Identify balances, payments, security interests, leases, and obligations that survive the transaction.
- Cash-flow and coverage model. Show the lender's definition of cash available for debt service and its required adjustments.
- Personal financial statement and liquidity evidence. Separate liquid acquisition funds from illiquid assets and contingent resources.
- Acquisition thesis and operating plan. Explain why customers will stay, who manages daily operations, what the seller does during transition, and how you'll replace the seller's work.
Treat an add-back as a proposition to verify. If the seller removes an owner's salary from adjusted earnings, include the cost of replacing the owner's necessary work. If a supposedly exceptional expense appears repeatedly, explain why it won't recur rather than automatically excluding it.
A checklist of business purchase loan criteria can help organize lender questions, but ask each institution for its own underwriting definitions.
Stress the cash flow, not just EBITDA
Debt-service coverage = cash available for debt service ÷ required debt service.
Agree on both components with the lender. EBITDA alone doesn't account for every cash obligation, and different treatment of capital spending, taxes, and working capital can change the apparent cushion.
Test distinct operating problems rather than applying a single pessimistic growth assumption:
- Revenue decline. Reduce sales without assuming all labor, rent, and administrative costs fall proportionately.
- Margin compression. Increase input or staffing costs and delay the assumed customer price increase.
- Largest-customer loss. Remove that customer's revenue and contribution margin, then identify which costs remain.
- Slower collections. Push receipts later while leaving payroll and supplier due dates unchanged.
- Transition disruption. Include replacement management, seller handover, and employee-retention costs where relevant.
For each case, show the lowest cash balance, repayment coverage, and any additional capital required. A business can remain profitable on paper while running short of cash.
Finish the historical records, earnings bridge, debt schedule, and liquidity evidence before requesting firm terms. Unsupported adjustments can cause lenders to reduce preliminary sizing, so resolve the largest disputed items before spending heavily on the rest of the transaction.
Negotiate Seller Financing and Partner Equity Terms
A seller note asks the seller to retain exposure after handing over control. That makes it a negotiation about trust and repayment, not just a request for a smaller closing payment.
In BizBuySell's first-quarter 2026 report, 61% of surveyed buyers hoped seller financing would be included, and 67% planned to use an SBA loan. Those intentions illustrate why seller credit and bank financing should be negotiated as compatible parts of a structure rather than competing alternatives.
Seller discussions should put the proposed obligations on paper.
Define the note before relying on it
Negotiate these terms together:
- Interest. Specify the rate, accrual treatment, and whether unpaid interest increases the balance.
- Maturity. Identify when the balance becomes due and how you expect to fund repayment.
- Payment schedule. Model permitted payments alongside senior obligations.
- Default triggers. Define breaches, notice requirements, cure rights, and remedies.
- Subordination. Establish the senior lender's priority and restrictions on seller enforcement.
- Standby. State whether principal or interest payments are prohibited and what ends that restriction.
Deferred fixed consideration and an earnout aren't interchangeable. A fixed note remains an obligation under its terms. A contingent payment requires an agreed performance measure, calculation method, reporting process, and dispute procedure.
If the valuation disagreement concerns customer retention, tie any contingent consideration to a clearly defined outcome rather than an ambiguous promise of future growth. Have counsel reconcile that mechanism with lender restrictions and the purchase agreement.
For additional structural context, Founder Connects discusses using seller financing to acquire businesses. Review potential seller-financing options before settling on a note whose repayment profile the business can't support.
Negotiate equity as an operating relationship
Partner equity requires different protections. Document your operating role, compensation, vesting arrangements, reserved decisions, information rights, and authority over additional borrowing.
Specify how distributions and sale proceeds are divided. Include buy-sell provisions addressing departure, incapacity, deadlock, and a partner's desire to exit.
A larger ownership percentage doesn't guarantee operating control. Read the voting and consent provisions alongside the economics.
Neither seller credit nor partner equity is free capital. One creates repayment and default exposure; the other allocates ownership and decision rights. Accept either only after modeling its consequences and obtaining approval from the parties whose agreements it affects.
Run the Raise in Stages From Offer to Close
A full approval is not the base case. In the Federal Reserve's 2025 report on employer firms, 42% of employer-firm financing applicants received the full amount requested. Treat every early indication as provisional until the lender, seller, and equity parties confirm the same terms in writing.
Run the raise against total uses: purchase price, transaction fees, working capital, and an operating cushion. If confirmed senior debt plus seller credit leaves a gap, that residual is equity or a revised price. Sequence commitments so the first signed promise is supported by the last verified condition.
Use the process map to distinguish preliminary coordination from executable funding.
Gate each funding decision
Complete the sources-and-uses schedule. Advance when each material expense has a documented estimate and a proposed eligible funding source. Sources should equal uses before the offer is firm, including fees due before closing and cash that must remain in the business after close.
Validate the underwriting model. Reconcile historical earnings, test adjustments, and run the downside cases. Proceed only when you can explain both repayment capacity and the cash reserve.
Obtain preliminary lender sizing. Before signing the letter of intent, establish an indicative debt range and the assumptions behind it. Ask which diligence findings could reduce that amount, then price the equity gap from the lower case.
Agree seller participation. Align the proposed seller amount, standby expectations, and lender consent before investor outreach. Send investors one coherent capital structure.
Raise the residual equity. Circulate transaction-specific materials showing the remaining requirement, governance terms, and downside exposure. Keep commitments conditional on the required diligence and approvals.
Verify executable commitments. Obtain written amounts, conditions precedent, collateral requirements, personal-guarantee exposure, amortization, covenants, and prepayment restrictions. Counsel should confirm how the documents interact before funding instructions are released.
Build the closing calendar from actual diligence and approval requirements, with dates owned by each party. Maintain a conditions tracker with a named owner, required evidence, and completion status for every outstanding item.

Check the failure points before releasing funds
- Unbudgeted fees. Refresh legal, lender, diligence, escrow, and advisory estimates as scope expands, then add them to uses before setting the equity ask.
- Unverified add-backs. Remove unsupported adjustments before accepting debt sizing.
- Empty operating accounts. Confirm retained cash separately from the seller's proceeds.
- Single-lender dependence. Keep a backup channel informed while staying accurate about parallel applications.
Treat an approval email as interim. Release funds only when the funding documents are executable, the outstanding conditions are understood, and the closing funds flow preserves the operating liquidity you planned to retain.
