Buying an existing LLC usually means one of two things: purchasing the membership interests of the current owners (you step into the same legal entity, keeping its EIN, licenses, contracts, and its liabilities), or an asset purchase where you form your own entity and buy only the pieces you want (equipment, inventory, customer lists, the trade name) while leaving most old debts behind. The right structure depends on what carries value in the target and how much of its history you are willing to inherit. Most first-time buyers of a small, revenue-generating LLC are better served by an asset purchase for liability protection, while a membership-interest (equity) purchase makes sense when non-transferable contracts, licenses, or long-standing vendor terms are the whole reason you are buying. Either way, the deal lives or dies on verified cash flow — and cash flow is also what lets you fund the acquisition and the working capital you will need the day after closing.
Key takeaways
- Two deal structures dominate: membership-interest (equity) purchases inherit the LLC's EIN, contracts, and liabilities; asset purchases let you buy only chosen assets under a fresh entity and leave most old debt behind.
- Small LLCs typically trade on a multiple of Seller's Discretionable Earnings (SDE) — often a low single-digit multiple for owner-operator businesses — not on revenue alone.
- Due diligence should verify revenue against bank deposits and tax returns, not just the seller's P&L; deposit history is the single most reliable proof of a business's true cash flow.
- A membership-interest purchase carries successor liability for unpaid taxes, lawsuits, and vendor debts — an indemnification clause and escrow holdback protect the buyer.
- Revenue-based funding and MCA marketplaces underwrite on the target's bank deposits and revenue rather than the buyer's credit, with common minimums near $10,000 and FICO floors around 500+.
- Post-close working capital is where many acquisitions stumble — payroll, inventory, and vendor deposits come due before the new owner's first collections clear.
- Funding tied to deposits can move in roughly 24–48 hours once statements are provided, but approval and terms are never guaranteed.
What You Are Actually Buying: Equity vs. Assets
Before you talk price, decide what changes hands. In a membership-interest purchase you buy the ownership units of the LLC itself. The entity does not change — same EIN, same bank relationships, same contracts, same lawsuits. That continuity is powerful when the value lives in things that are hard or impossible to reassign: a state license, a franchise agreement, a government contract, a lease with below-market rent, or vendor terms built over a decade. The catch is successor liability: you inherit the good and the bad, including tax debt or claims you did not know about.
In an asset purchase you create a new LLC and buy specific assets — equipment, inventory, the customer list, the phone number, the brand. Old liabilities generally stay with the seller's entity. This is cleaner for the buyer and is the default for most small main-street deals. The trade-off is reassignment friction: leases, permits, and key contracts may need landlord or counterparty consent, and you may have to re-apply for licenses.
Neither is universally correct. Match the structure to where the value and the risk actually sit in the specific company in front of you.
How to Value an Existing LLC
Small, owner-operated LLCs are priced on earnings, not revenue. The standard yardstick is Seller's Discretionary Earnings (SDE) — net profit added back to the owner's salary, personal expenses run through the business, interest, depreciation, and one-time costs. A profitable owner-operator business commonly sells for a low single-digit multiple of SDE; more systematized businesses with a management team in place command higher multiples because the buyer is not purchasing a job.
Three adjustments matter most. First, normalize the add-backs — a seller who adds back their own full-time labor is selling you a business that needs a manager you now must pay for. Second, separate transferable revenue from revenue that walks out the door with the seller (a business built entirely on the owner's personal relationships is riskier than one built on contracts and recurring accounts). Third, treat customer concentration as a discount: if one client is 40% of revenue, the multiple should reflect that fragility.
Value is a hypothesis. Due diligence is where you confirm it.
Due Diligence: Verify Cash Flow, Not the Pitch
The seller's profit-and-loss statement is a claim. Your job is to prove or disprove it against sources the seller cannot easily dress up. Reconcile the P&L to filed tax returns and to 12–24 months of business bank statements. Deposits are the truth serum of a small business — if the deposits do not support the stated revenue, the stated revenue is wrong. As an underwriter, bank-deposit history is the first thing we read, and it should be the first thing you read too.
Beyond the numbers, build a checklist and refuse to close until each item is cleared:
- Financial: tax returns, bank statements, A/R aging, outstanding debts and liens (run a UCC search), sales tax and payroll tax standing.
- Legal: the operating agreement, pending or past litigation, and confirmation the seller has authority to sell.
- Operational: lease terms and assignability, key contracts and their change-of-control clauses, licenses and permits, employee and 1099 status.
- Commercial: customer concentration, supplier terms, online reviews and reputation, and whether the seller will stay on for a transition.
If you are buying membership interests, a tax-clearance certificate from the state and an escrow holdback against undisclosed liabilities are non-negotiable protections.
How to Fund the Purchase
Acquisition financing for small LLCs is rarely one clean loan. Buyers usually assemble a stack. Seller financing — where the seller carries part of the price as a note — is common and doubles as a confidence signal: a seller willing to get paid over time believes the business will keep performing. Bank and SBA-backed loans offer the lowest cost of capital but are slow, paperwork-heavy, and lean hard on the buyer's personal credit and collateral, which sinks many otherwise good deals.
The gap those options leave — speed, a thin buyer credit file, or the working capital you need after closing — is where revenue-based funding and MCA marketplaces fit. These underwrite primarily on the target business's bank deposits and revenue rather than the buyer's FICO, which is decisive when you are acquiring a healthy business but do not personally have pristine credit or hard collateral. Typical parameters: minimums near $10,000, credit floors around FICO 500+, and decisions in roughly 24–48 hours once bank statements are in hand. Repayment is structured as a share of ongoing cash flow, so it flexes with the business's deposit rhythm rather than demanding a fixed bank-style payment on day one. Approval and terms are never guaranteed — they follow the deposits.

Decision Framework: When Each Approach Fits
Structure and funding are not matters of taste — they follow the facts of the deal.
An equity (membership-interest) purchase works best when the value depends on non-transferable licenses, contracts, or vendor terms; when the entity has clean books, verified tax standing, and no litigation; and when you have negotiated strong indemnification and an escrow holdback. Avoid an equity purchase when the target has messy or unfilmable tax history, open lawsuits, or liabilities you cannot fully quantify — the successor liability is not worth the continuity.
An asset purchase works best when you want a clean liability break, the key assets and customer relationships transfer easily, and you can re-secure the licenses and leases you need. Avoid an asset purchase when the whole value is a contract or license that cannot be reassigned — in that case you would be paying for something you cannot actually take.
Revenue-based / marketplace funding works best when the target has strong, verifiable deposits, you need to close or capitalize fast, and the buyer's credit or collateral would stall a bank. Avoid it when the business has thin or highly seasonal deposits that cannot comfortably support a cash-flow-based repayment, or when a low-cost SBA loan is realistically within reach on your timeline — then patience is cheaper than speed.
Worked Example: Sizing an Acquisition Deal
The figures below are illustrative, provided for example only to show how the pieces fit — not a quote or a promise of terms.
| Deal element | For example | What it tells the buyer |
|---|---|---|
| Trailing 12-mo revenue (bank-verified) | $720,000 | Deposits, not the P&L, anchor the underwriting. |
| Seller's Discretionary Earnings (SDE) | $150,000 | The earnings base a multiple is applied to. |
| Agreed purchase price | Low single-digit SDE multiple | Price reflects owner-operator dependence. |
| Seller note (carried by seller) | Portion of price | Seller confidence; reduces buyer's upfront need. |
| Revenue-based funding (post-close capital) | ~$50,000 range | Covers payroll, inventory, and vendor deposits before first collections clear. |
| Underwriting basis | Target's deposits + revenue | Approval follows the business's cash flow, not just buyer FICO. |
| Indicative time to funds | 24–48 hours after statements | Speed the acquisition timeline usually requires. |
Notice what this table does not do: it does not multiply a factor rate against the advance to print a fixed payback figure. Cash-flow funding is repaid as a share of ongoing deposits, so the real cost is a function of how the business performs, and it should be modeled against your post-close collections — not treated as a single lump sum.
The First 90 Days: Don't Run Out of Cash After You Win
The most common way a sound acquisition goes wrong is a working-capital squeeze in the first quarter of ownership. Payroll, rent, insurance, supplier deposits, and any transition costs come due immediately, while the accounts receivable you bought take their usual 30–60 days to convert to cash in your account. Meanwhile some customers wait to see whether the new owner performs before they reorder.
Plan the bridge before closing, not after. Map the outflows for the first 90 days against a conservative estimate of collections, and size a working-capital cushion — often through revenue-based funding secured against the business's own deposits — so you are never choosing between making payroll and paying a key supplier. Retaining the seller for a short transition and keeping key staff and top customers informed protects the very cash flow your funding is underwritten on. The buyers who thrive are the ones who treated day-one liquidity as part of the purchase price, not an afterthought.
Frequently asked questions
Should I buy the LLC's membership interests or just its assets?
Buy membership interests when the value depends on things that are hard to transfer — licenses, franchise or government contracts, favorable leases, or long-standing vendor terms — and the entity's books and tax standing are clean. Choose an asset purchase, which forms a new entity and buys only chosen assets, when you want a clean break from the seller's liabilities and the key assets and relationships transfer easily. Most small main-street deals default to asset purchases for that liability protection.
What liabilities do I inherit when buying an existing LLC?
In a membership-interest (equity) purchase you inherit the entity's liabilities — including unpaid taxes, pending lawsuits, vendor debts, and UCC liens — under successor liability, even ones you did not know about. Protect yourself with a UCC lien search, a state tax-clearance certificate, a strong indemnification clause, and an escrow holdback. An asset purchase generally leaves most old liabilities with the seller's entity.
How do I verify the seller's revenue is real?
Reconcile the seller's profit-and-loss statement against two independent sources they cannot easily manipulate: filed business tax returns and 12 to 24 months of business bank statements. Bank deposits are the most reliable proof of true cash flow — if deposits do not support the stated revenue, the revenue claim is wrong. This is also exactly what a revenue-based funder examines first.
Can I get funding to buy a business if my personal credit isn't great?
Yes. Revenue-based funding and MCA marketplaces underwrite primarily on the target business's bank deposits and revenue rather than the buyer's credit, with common minimums near $10,000 and FICO floors around 500+. That makes them a fit when you are acquiring a healthy, cash-generating business but lack pristine personal credit or hard collateral. Approval and terms follow the deposits and are never guaranteed.
How is a small LLC priced?
Small owner-operated LLCs are typically priced on a multiple of Seller's Discretionary Earnings (SDE) — net profit plus the owner's compensation, personal expenses, interest, depreciation, and one-time costs — usually a low single-digit multiple for owner-operator businesses. Businesses with a management team in place and recurring, transferable revenue command higher multiples because the buyer is not just purchasing a job.
How fast can acquisition funding move?
Bank and SBA-backed loans typically take weeks to months due to documentation and credit review. Revenue-based funding tied to the target's bank deposits can move in roughly 24 to 48 hours once statements are provided, which is often what the acquisition timeline requires. Speed comes from underwriting on cash flow rather than exhaustive personal-credit and collateral analysis.
Why do I need working capital after buying the business?
Because your outflows arrive before your inflows. Payroll, rent, insurance, and supplier deposits come due immediately, while the accounts receivable you acquired take their normal 30 to 60 days to convert to cash in your account. A working-capital cushion — often revenue-based funding secured against the business's own deposits — bridges that gap so you never have to choose between making payroll and paying a key supplier.
Is seller financing a good sign?
Generally yes. When a seller agrees to carry part of the purchase price as a note, they are betting the business will keep performing well enough to pay them over time — a meaningful confidence signal. It also reduces your upfront capital need and can be combined with revenue-based funding for post-close working capital. Still verify the deal on its own merits; a seller note lowers risk but does not replace due diligence.
