How to Offer Customer Financing for Small Businesses

There are two ways to let customers pay over time, and the choice between them is really a choice about who absorbs the loss when a customer does not pay.

Run it in house and you set the terms, keep the full sale price, and carry every unpaid invoice yourself. Use a third-party provider and you are paid up front, usually within a couple of days, minus a fee of roughly 3% to 6%, and the provider carries the default.

For most small businesses, the second option is the right one, and the reason is not the fee. It is that assessing creditworthiness and chasing late payers are specialist functions, and a six-person bakery has neither the data nor the staff to do either well. Third-party platforms now make finance for customers of small businesses available to companies that could never have run a credit desk of their own.

Terms also run in both directions. The payment-history file a packaging supplier reads before granting you net-30 is the same kind of file you will be reading on a restaurant that wants terms from you, so starting business credit from scratch and granting credit to buyers are two halves of one subject.

But the in-house route is not always wrong, and for a wholesale operation invoicing the same twenty restaurant accounts every week it is often the only version that makes sense. This guide covers both: what each costs, who carries which risk, how to set terms that do not wreck your own cash position, and when the right answer is to decline.

Key Takeaways

• Third-party providers charge roughly 3.29% to 6% plus $0.30 per transaction and absorb the default risk. In-house financing costs no fee and leaves you holding every bad debt.
• Merchant costs by provider: Klarna 3.29%–5.99%, Afterpay 4%–6%, Affirm around 6% and as wide as 2.9%–8.9% depending on terms and category.
• Installment options lift conversion by roughly 20% in retail settings, though the average-order-value claims circulating are mostly provider marketing and range implausibly widely.
• Consumer BNPL suits single transactions in the $50 to $500 band. Recurring wholesale accounts are better served by your own net-15 or net-30 terms.
• Extending terms converts revenue into receivables, which means your own cash gap widens before it narrows, so size it before you offer it.
• Whatever you offer, write the terms down: amounts, due dates, late fees, what happens to deliveries when an account goes past due.

Why customers ask to pay over time, and when it is worth offering

Installment payment removes the upfront cost barrier, which is the single most common reason a ready buyer walks away. Retailers who implement buy-now-pay-later properly see conversion rates climb by roughly 20%, and cart abandonment drop materially where the alternative is paying in full at checkout.

Treat the headline figures around order value with care, though. Published AOV-lift claims range from +17% to over +200% depending on who measures and how, and nearly all of them come from providers with an interest in the number. The conversion effect is well supported. The spending-more effect is mostly marketing.

Offering terms tends to be worth it when:

• Your average order is large enough to be a decision. Consumer installment plans work best between impulse buys and considered purchases, broadly the $50 to $500 range.
• You are losing sales at the price conversation. A caterer quoting $4,000 for a wedding and watching prospects go quiet has a financing problem, not a pricing problem.
• Your competitors offer it and you do not. In categories where terms are standard, wholesale supply especially, no terms reads as a refusal to do business.
• Volume growth is worth a margin point. The fee is only expensive if the incremental sales do not materialize.

And it is usually not worth it when your orders are small and frequent, when your margin cannot absorb 4% to 6%, or when the customers asking for terms are the ones already paying you late.

In-house vs third-party financing: what each actually costs

The two models differ on every dimension that matters, not just price.

Published merchant rates as of 2026: Klarna 3.29%–5.99% plus $0.30, Afterpay 4%–6% plus $0.30, Affirm around 6% with a stated range of 2.9%–8.9% depending on loan term, category and volume (Gr4vy, 2026). For context, ordinary card processing runs about 2.5% to 3.5%, so financing costs roughly one to three points more than taking a card.

The fee is the visible cost of the third-party route. The invisible cost of the in-house route is larger and lands unevenly: the hours spent chasing payment, the invoices never collected, and the gap between delivering goods and being paid for them — which your own suppliers, lenders and payroll do not wait for.

How to set up third-party customer financing

Four steps, and most of the work is in the first one.

1. Match the provider to your transaction size and customer type. Consumer BNPL providers handle retail-sized orders at checkout. B2B terms platforms underwrite business buyers and pay you up front on net-30 or net-60 invoices, which is the relevant category if your customers are restaurants, florists or retailers rather than individuals.
2. Price the fee into your margin honestly. Take your actual gross margin, subtract the merchant rate, and decide whether the resulting number still works at your current volumes. If 6% takes a 22% margin to 16%, the plan needs to bring enough extra volume to cover it.
3. Integrate where the decision happens. At the point of quote for a caterer, in the checkout for an online store, on the invoice for wholesale accounts. Financing offered after the buyer has already hesitated converts far worse than financing visible while they are deciding.
4. Reconcile the settlements. Providers remit net of fees and on their own schedule, so your bookkeeping needs to tie each payout to the originating orders. Getting this wrong makes revenue look smaller and fees look larger than they are.

Keep your team briefed, too. Whoever answers the phone and whoever hands over the order will be asked how the payment plan works, and a driver who cannot answer “can I pay the rest later?” costs you the sale at the door. Clear internal answers are part of the setup, in the same category as the rest of the support and perks that keep front-line staff able to represent you well.

How to offer terms in house without wrecking your cash flow

If you are invoicing the same wholesale accounts repeatedly, in-house terms are often the only practical structure. Done carelessly, they become an interest-free loan book you never agreed to run.

• Write the terms down. Payment window, accepted methods, late fee, and what happens to future deliveries when an account goes past due. A one-page terms sheet signed at account opening prevents most disputes.
• Start short and extend on performance. New accounts begin at net-15 or payment on delivery. Accounts that pay cleanly for six months earn net-30. Terms are a privilege with a track record attached, not a default.
• Set a credit limit per account and enforce it. A limit that is never enforced is not a limit. The purpose is to cap the loss from a single customer failing, which happens to every business eventually.
• Check before you extend. Business credit reports are not protected the way consumer reports are, so you can look up a prospective wholesale buyer’s payment history before granting terms. A PAYDEX in the 50s tells you what the account will do to you.
• Offer an early-payment discount. Something like 2/10 net 30, which is 2% off for paying within ten days, costs you less than a financing fee and pulls cash in weeks earlier.
• Chase on a schedule, not on a mood. A reminder at day 7 before due, day 1 after, day 15 and day 30, sent automatically, collects far more than sporadic awkward phone calls.
• Stop delivering on badly past-due accounts. This is the hard one, and the one owners skip. An account that is 60 days late and still receiving weekly deliveries is accumulating a larger loss every week.

Watch the operational detail where deliveries and payment meet, too. If drivers collect payment on the route, the cash handling and card-acceptance practices there are part of your credit exposure: chargebacks and card-present disputes on delivery hit a business the same way bad debt does, and they belong in the same written policy as your payment terms.

What extending terms does to your own cash position

Offering financing moves money out of your bank and into your receivables, and the gap opens before the benefit arrives. A wholesale baker who shifts twenty accounts from payment-on-delivery to net-30 has, in effect, pre-funded a month of those customers’ purchases — while flour, fuel, rent and wages carry on weekly.

So size the hole before you open it. Multiply the monthly revenue of the accounts going onto terms by the terms length in months. That is roughly the working capital the decision consumes, and it needs to come from somewhere: cash reserves, a line of credit, or a third-party provider who pays you up front instead.

Where that funding comes from is a decision with its own constraints. If a revolving line is the plan, it is worth knowing the requirements lenders apply to a business line of credit before you commit to terms that depend on being approved for one. And if the plan involves borrowing against the receivables you are about to create, the question of how much business debt is healthy to carry should be answered first, because receivables-funded growth is still leverage.

There is a cheaper intermediate step worth knowing about: a business credit card used deliberately as a float on your own purchasing can cover a 30-day receivables gap at no interest if cleared each cycle, and the easiest business credit cards to get are available to companies well short of qualifying for a line. It is a narrow tool rather than a funding strategy, but it fits exactly this gap.

Which metrics tell you whether the program is working

Track four numbers from the month you start, because the fee is certain and the benefit is not.

• Incremental conversion. The share of quotes or carts that close with financing available, against your baseline before. This is the number the whole program rests on.
• Days sales outstanding (DSO). Average days between invoicing and payment. In-house terms raise it; a third-party provider who pays up front should leave it roughly flat.
• Bad debt as a share of revenue. Only meaningful on in-house terms, where it is the true cost of the program. Over 1% to 2% suggests your credit decisions need tightening.
• All-in financing cost. Provider fees plus collections time plus write-offs, as a percentage of financed revenue. Compare it against the gross margin on the incremental sales, not against your total revenue.

If you move further into offering terms at scale, the discipline starts to resemble running a small lending book, and the metrics lenders use (approval rates, delinquency curves, portfolio yield) become relevant. A rundown of the KPIs lending businesses measure is a reasonable primer on what to watch once an in-house program has real volume behind it.

Also watch where the demand is concentrated. Businesses with routes across several metros often find terms requests cluster in specific markets. The accounts in a city where you have recently expanded delivery coverage, such as a newer market like Little Rock, tend to be the newest and least-proven, which is exactly where credit limits earn their keep.

When to say no to a customer asking for terms

Declining is a legitimate answer, and the signals are usually visible in advance.

• The customer is already late on an existing balance with you.
• Their business credit file shows a pattern of slow payment to other suppliers.
• The order is large relative to your monthly revenue, so a single default would be material.
• The margin on the order cannot absorb a financing fee or a write-off.
• They want terms longer than your own payables, which makes you the bank in the arrangement.
• Something about the urgency does not add up: rush orders on new terms from unfamiliar accounts are a recognizable pattern.

A clean alternative keeps the sale alive: payment on delivery for the first few orders, a deposit with the balance on delivery, or a third-party provider who will underwrite the buyer so you do not have to.

Frequently Asked Questions

How can a small business offer financing to customers?

Two routes. Partner with a third-party provider (a consumer BNPL platform for retail-sized orders, or a B2B terms platform for business buyers), which pays you up front for a fee of roughly 3% to 6% and carries the default risk. Or extend your own terms, typically net-15 or net-30, which costs no fee but leaves you managing credit decisions, collections and bad debt.

What does it cost to offer customer financing?

Third-party providers charge merchants roughly 3.29% to 6% plus about $0.30 per transaction, with Affirm quoting as wide as 2.9% to 8.9% depending on loan term, category and volume. In-house financing has no provider fee, but costs you the working capital tied up in receivables, collections time, and unrecovered bad debt.

Does offering financing increase sales?

Conversion, reliably: installment options lift retail conversion by roughly 20% where the upfront price is the barrier. Claims about higher average order values are far less dependable, ranging from +17% to over +200% across sources, most of them published by providers.

Is in-house financing ever better than using a provider?

For recurring B2B accounts, often yes. If you invoice the same wholesale customers every week, net-30 terms are the industry norm, cost no percentage fee, and are easier to administer at volume than a per-transaction financing product. The requirement is a written terms sheet, per-account credit limits, and the willingness to stop deliveries when an account goes badly past due.

What credit checks should I run before extending terms?

For business customers, pull a business credit report. They are not protected the way consumer reports are, so a payment-history check on a prospective wholesale account is straightforward and tells you how the account treats its other suppliers. For consumers, do not attempt your own credit assessment; a third-party provider’s underwriting is both better and keeps consumer lending compliance out of your business.

Pick the model that matches your customers

The decision is mostly determined by who buys from you. One-off consumer and business purchases in the $50 to $500 band belong with a third-party provider: you are paid up front, the fee is predictable, and the default is someone else’s problem. Recurring wholesale accounts belong on your own net-15 or net-30 terms, with written limits and a collections schedule.

Either way, work out what the arrangement does to your own cash before you offer it, and track conversion against the all-in cost from the first month. Financing that brings volume you can fund is a growth lever. Financing that quietly turns your customers into borrowers you never underwrote is a slow leak.
