When you're buying an ecommerce business, how you structure the financing is just as important as the price you pay. Two options dominate the ecommerce acquisition market: seller financing and SBA loans. Each has real advantages — and real traps. Choosing wrong can cost you hundreds of thousands of dollars in opportunity cost or cash flow strain.
This guide breaks down seller financing vs SBA loan options in plain terms, with the real numbers and deal scenarios you'll actually encounter.
What Is Seller Financing?
Seller financing (also called a seller note) means the person selling the business agrees to receive a portion of the purchase price over time — rather than all cash at closing. You make regular payments to the seller instead of (or in addition to) a bank.
Example: You're buying a $500,000 Shopify business. Instead of paying $500,000 at close, you pay $400,000 at close and $100,000 over 3 years at 6% interest. The seller carries a $100,000 note.
Seller notes typically represent 10-30% of the purchase price, carry interest rates of 5-8%, and have 2-5 year terms. They're subordinated to any senior debt (your bank loan) meaning the bank gets paid first.
What Is an SBA Loan?
The SBA 7(a) loan is a government-guaranteed bank loan designed for small business acquisitions. The SBA guarantees 75-85% of the loan, which allows lenders to approve deals they'd otherwise pass on.
Key terms in 2026:
- Down payment: 10-15% of purchase price
- Loan amount: Up to $5 million
- Term: Up to 10 years
- Interest rate: Prime + 2.25%-2.75% (currently approximately 10.5-11%)
- Fully amortizing, no balloon payment

Side-by-Side Comparison
| Factor | SBA Loan | Seller Financing | |---|---|---| | Down payment required | 10-15% | Often 0-20% depending on deal | | Interest rate (2026) | ~10.5-11% | 5-8% (negotiated) | | Loan term | 7-10 years | 2-5 years | | Lender approval required | Yes (30-90 day process) | No (just you and seller) | | Maximum loan amount | $5M | Unlimited (whatever seller agrees to) | | Personal guarantee required | Yes | Negotiated | | Eligible businesses | 2+ years history, 1.25x DSCR | Any (seller decides) | | Closing timeline | 60-90 days | 30-45 days | | Assumable by next buyer | No | Often yes | | Flexibility | Low (SBA terms are fixed) | High (fully negotiated) |
When SBA Financing Wins
Larger Deals ($500K+)
For acquisitions above $300-400K, SBA financing is almost always the right primary instrument. The 10% down payment is dramatically more capital-efficient than trying to negotiate 100% seller financing.
On a $750,000 acquisition: SBA gets you to close with $75,000 down. Without SBA, you'd need significantly more cash or seller cooperation.
Businesses With Clean 2+ Year Financials
SBA lenders have standardized this process. If the business has 2 years of tax returns showing consistent SDE, a 1.25x+ DSCR at your loan amount, and no account health issues — SBA is the most straightforward path to financing.
When You Want Lowest Monthly Payment
SBA's 10-year terms spread payments over a long period, keeping monthly cash flow manageable. A $450,000 SBA loan at 10-year terms runs approximately $5,900/month. The same amount as a 3-year seller note would be ~$14,000/month.
When the Seller Wants All-Cash at Close
Many sellers — especially those working with brokers — want clean all-cash at close. They don't want to remain financially tied to a business they've exited. SBA financing lets you give the seller their cash while you repay a bank over 10 years.
When Seller Financing Wins
Businesses That Don't Qualify for SBA
Not every ecommerce business is SBA-eligible. Businesses with less than 2 years of history, declining revenue, or DSCR below 1.25x often can't get SBA approval. Seller financing may be the only way to finance the deal.
Faster Closings
SBA takes 60-90 days from application to close. Seller-financed deals can close in 30-45 days. If you're competing with other buyers, speed matters.
Small Acquisitions ($50K–$250K)
SBA lenders are less interested in small loans. The economics don't work well for them on deals under $150-200K. Seller financing is often the only realistic option for micro-acquisitions — and honestly, the right one. At this size, you may be able to negotiate 50-80% seller financing with a modest down payment.
More Favorable Interest Rate
Seller note interest rates (5-8%) are lower than current SBA rates (~10.5-11%). If a seller will carry a large note, you pay less interest. The trade-off is shorter repayment terms (3-5 years vs. SBA's 10 years), which increases monthly payments.
The Best Structure: Combining Both
In practice, the most common and most optimal structure for mid-market ecommerce deals combines SBA financing with a seller note:
Example: $600,000 acquisition
| Component | Amount | Terms | |---|---|---| | Buyer cash (down payment) | $60,000 (10%) | — | | SBA 7(a) loan | $480,000 (80%) | 10 years, ~10.75% | | Seller note | $60,000 (10%) | 5 years, 6% | | Total | $600,000 | — |
Monthly payments:
- SBA loan: ~$6,500/month
- Seller note: ~$1,150/month
- Total debt service: ~$7,650/month = $91,800/year
Required SDE for 1.25x DSCR: $114,750
For a business generating $150K SDE, this structure leaves $58,200/year ($4,850/month) of cash flow above debt service — healthy headroom.
SBA lenders actually prefer this structure because the seller note signals the seller's confidence in the business post-close. Many lenders require or encourage seller notes on acquisition deals.
Seller Note Negotiating Points
If you pursue seller financing (either standalone or alongside SBA), these are the key terms to negotiate:
Interest rate: 5-7% is standard. Push back on anything above 8%.
Term: 3-5 years for standalone seller notes. If combined with SBA, the SBA limits seller note terms and requires them to be on standby for the first 2 years (meaning the seller can't call the note if you're in default with the bank).
Subordination: The bank will require the seller note to be fully subordinated. The seller gets paid after the bank. This is non-negotiable for SBA deals.
Standby period: For SBA deals, seller notes are typically on "standby" — meaning no principal payments are made to the seller — for the first 24 months. Interest may still be paid. Confirm this with your lender.
Collateral: Sellers may request a personal guarantee from you. Reasonable. They may also request a lien on business assets — negotiate this carefully since the bank already holds a first lien position.
Prepayment: Negotiate the right to prepay the seller note without penalty if your cash flow allows it.
Common Mistakes When Choosing Financing
Defaulting to all-cash when SBA is available: If you can get SBA approval, using all cash to buy an ecommerce business is almost always the wrong capital allocation. Preserve cash for working capital, inventory, and growth.
Underestimating SBA timeline: First-time buyers frequently underestimate how long SBA takes. If you tell a seller "I can close in 30 days" and you need SBA financing, you'll miss that date. Build 75-90 days into your LOI exclusivity period.
Not modeling the DSCR before making an offer: It's crushingly common for buyers to make offers and then discover the deal doesn't cash flow well enough to meet SBA's 1.25x DSCR requirement. Run the numbers first with our SBA affordability calculator.
Accepting seller note terms without negotiating: Sellers often start with aggressive seller note terms — high rates, short terms, personal guarantees. Everything is negotiable. Come in with a counter.
Ignoring working capital in the financing structure: Most acquisition loans don't include working capital. Plan separately for the cash you'll need to fund inventory, ad spend, and operations in the first 90 days.
How to Decide: A Decision Framework
Ask yourself these four questions:
-
Does the business qualify for SBA? (2+ years of history, 1.25x DSCR) → If yes, SBA should be your primary instrument.
-
What's the deal size? → Under $200K: seller financing may be your only option. Over $400K: SBA is almost always the right primary structure.
-
How fast does this need to close? → Competitive situation with multiple buyers? Seller financing or all-cash wins on speed. No competition? SBA is fine.
-
Is the seller willing to carry a note? → Even with SBA, ask. A 10% seller note reduces your loan amount and often gets the deal done at better terms.
For most mid-market ecommerce acquisitions ($300K–$1.5M), the answer is: SBA primary + seller note secondary + buyer down payment. This structure is maximally capital-efficient and aligns everyone's incentives.

Frequently Asked Questions
Can I use both seller financing and an SBA loan on the same deal?
Yes — and this is actually the most common structure. SBA allows seller notes that are fully subordinated to the SBA loan. The seller note typically represents 5-15% of the purchase price. The SBA has specific rules about seller note standby periods; your lender will walk you through the requirements.
What interest rate should I expect on a seller note?
Seller note interest rates typically range from 5-8% in 2026. This is below current SBA rates (~10.5-11%), making seller note portions of the deal cheaper to service. Push back on any seller note above 8% — that's above market.
Do I need good credit for seller financing?
Credit matters less for pure seller financing than for SBA loans. Sellers care primarily about their confidence in your ability to operate and grow the business, not your FICO score. For SBA deals, however, you still need 650+ personal credit.
What happens if I can't make seller note payments?
If you default on a seller note, the seller's recourse depends on the note terms. If the seller has a personal guarantee from you, they can pursue you personally. If the note is secured by business assets, they may have a claim on those assets (though subordinated to the bank's first lien). Missed seller note payments typically don't trigger the same immediate consequences as bank defaults.
Is seller financing common in ecommerce acquisitions?
Yes — roughly 50-70% of mid-market ecommerce acquisitions include some form of seller financing, even when the deal is primarily SBA-funded. Full seller financing (no bank involvement) is less common above $300K but does happen, especially in off-market deals.
Before you make an offer on any ecommerce business, model both financing scenarios. Use our loan calculator to see exact monthly payments and DSCR under SBA terms, then compare against a seller note structure. The numbers will tell you which path makes sense.
