How to Offer Financing to Customers: In-House or Third Party

Customer financing is simply structured payment over time. On a high-ticket buy, few people want to pay the full amount today, so financing lets them commit now and pay in pieces.

There are two broad models. In-house financing means your business extends the credit itself. Third-party financing means an outside provider funds the buy, and the customer repays that provider. Both let the buyer spread the cost, but they split responsibility very differently.

The rest of this guide runs each model against the same three questions: who is the lender, what happens to your cash, and where the risk sits. Answer those, and the right path usually becomes clear.

The lender is different in each model, so name it clearly before you commit. Here is the split at a glance:

Question · In-house financing · Third-party financing

• Who is the lender? · Your own business · The provider or its named originating lender
• Who does the customer owe? · Your business · The provider
• Who decides approval? · Your business · The provider, under its own underwriting
• Who collects payments? · Your business · The provider

In the third-party model, the provider is the lender. For example, Affirm's financing is originated by Affirm's lending partners, including Cross River Bank, Sutton Bank, or Celtic Bank. Klarna's financing is originated by WebBank, Member FDIC. Naming the lender is not a formality — it tells you who carries the credit relationship.

In the in-house model, there is no outside lender, so your business plays that role. You own the whole cycle: the decision, the collection, and the fallout when a payment is missed.

Think about cash flow first. When you finance in-house, you deliver the product now but collect slowly. That gap sits on your books, and on a high-ticket sale it can tie up real money for a long stretch.

Next, consider risk. If a customer stops paying, that loss is yours, and no outside party absorbs it. You also handle the reminders, the records, and any collection work.

Above all, mind the legal side. Extending credit in your own name can carry lending-law duties — licensing, disclosures, and rules that vary by state. This guide does not give legal advice, and no structure is automatically lawful where you operate. Before you build an in-house plan, read our guide on whether you need a license to offer payment plans. If you run a coaching business, see how to offer coaching payment plans without becoming the lender.

Start with the agreement. In this model, the customer signs with the provider, not with you, so the provider — not your business — is the party the customer owes.

Now the approval question. Every approval decision belongs to the provider, under its own underwriting. Your business does not decide, speed, or influence that outcome. A soft check is common at prequalification with providers like Affirm and Klarna, but each provider sets its own rules, so confirm the details against each provider's published terms.

Funding and risk vary by provider, so read the details for each one. SplitIt uses the customer's existing card credit and leaves normal card risk with the merchant; keep that distinction in every funding discussion. SplitIt is the exception here — it is not lender-funded, the merchant is funded per installment as each installment is charged, and chargebacks work like any normal card charge. That is very different from other providers, so never carry one provider's funding facts over to another.

Financing disclosure: All financing is subject to credit approval. Ranges shown are typical; every provider sets limits per customer and per merchant, and approved amounts, terms, and rates vary by applicant. Availability of any given provider depends on your industry, ticket size, and underwriting outcome. Not every provider is available to every merchant. Loans and financing are originated by the lending partners named above: Affirm's lending partners (Cross River Bank, Sutton Bank, or Celtic Bank) and Klarna's WebBank, Member FDIC. SplitIt places an authorization hold against the available credit on the customer's existing credit card and charges installments to that card over time; the customer needs enough available credit to cover the entire purchase at checkout, and debit or prepaid cards are not supported.

Ask yourself these questions in order:

1. Cash: Can your business wait weeks or months for full payment? If not, a third-party path pays you for the sale sooner.
2. Risk: Can you absorb a customer who stops paying? In-house means that loss is yours, whereas a third-party provider carries the credit risk in most models.
3. Legal: Do you want lending-law duties? In-house may pull you into licensing and disclosure rules, while third-party keeps the lending relationship with the provider.
4. Control: How much of the process do you want to run yourself? In-house gives you full control and full responsibility.

For many high-ticket businesses, the third-party path is easier to start: the provider is the lender, the provider decides approval, and the customer's agreement is with the provider. Still, the right answer depends on your cash position and your appetite for risk. There is no single winner — only the model that fits your numbers.

Here is a short checklist for the third-party path:

1. Checkout: A checkout that can show and process the financing option. PayFull helps merchants present financing inside their own checkout.
2. Merchant account: Your own merchant account, in your business's name.
3. Provider agreement: A signed agreement with each provider you want to offer, since you keep your own provider agreements.
4. Underwriting handoff: A clear path for the provider to run its own decision on each customer.

For in-house financing, the list looks different. You need written credit terms, a way to track balances and payments, a collection process, and — critically — a review of the lending-law duties that come with extending credit in your own name.
