Merchant of Record, PayFac or Processor: Which Lets You Add BNPL?

Each label describes a role in a deal, not a tool you buy. A merchant of record is the legal seller to the customer. A payment facilitator lets sub-merchants transact under its own master account. A payment processor moves card data between the bank, the card network and the merchant. Three jobs carry three sets of duties.

The merchant of record holds the heaviest role. For a full definition, see the guide on offer terms and records on a financed sale. We link out rather than restate it, because the term carries contract-specific meaning you should read in full.

Here is a plain breakdown of the three:

• Merchant of record: the legal seller to the buyer, named on the receipt, carrying tax, refund and chargeback duty.
• Payment facilitator (payfac): onboards sub-merchants under its own master account, so sub-merchants transact without each opening a full merchant account.
• Payment processor: moves transaction data between parties and does not take on the seller's refund role.

One note matters above all: these roles can overlap in a real contract. A single company may act as both facilitator and processor. Read your own agreement to see which roles your setup actually assigns.

The label matters because it decides who the buyer deals with — and who owes the refund — when financing enters checkout. Adding a buy now, pay later option does not move those duties by itself. Your existing model still sets who is the seller of record and who handles disputes. The financing provider makes its own call on the buyer and does not inherit your refund role.

This is where people trip up. They assume that adding financing changes their business model, yet it usually does not. The financing provider underwrites the buyer and funds the sale under its own agreement, while your model still sets who the customer sees as the seller. The two layers sit side by side rather than merging.

Above all, remember one fact about every model: every approval and eligibility decision belongs to the financing provider, under its own underwriting. No model you pick speeds, influences or guarantees that decision.

The customer relationship and refund duty sit with different parties depending on your model. The party named as the seller of record holds the relationship, and that same party usually owns the refund and dispute duty.

A few cautions apply. Structures vary by contract and by provider, so treat any summary as a starting map, not a legal rule. Never assume a vendor is your merchant of record unless its own published terms say so. We name no company in that role here, because no supplied source establishes one.

How the roles line up

• Merchant of record (you): you are the legal seller named on the receipt and you own the refund and dispute duty.
• Merchant of record (a third party): that third party holds the relationship and the refund duty only if its own terms say so.
• Payment facilitator: the sub-merchant usually holds the relationship, though the payfac may share duties per contract.
• Payment processor: you hold the relationship and the refund duty, because the processor is not the seller.

One thread still runs through every row: you keep your own merchant accounts and provider agreements regardless of which model describes your setup. Adding financing does not hand those over to anyone.

Refunds, fulfillment and disputes follow the seller of record. The model that names you as seller keeps those duties with you. When you are the merchant of record, you issue the refund, ship the goods and answer the chargeback. When a third party is the merchant of record, those duties may shift to it, but only if its own terms say so.

The financing layer adds a second track. A financing provider funds the sale and collects from the buyer on its own schedule. The goods still come from you, and the service dispute still runs through the seller of record. In other words, the money path and the fulfillment path can differ. You handle where refunds and disputes land through your own flow; see how disputes are handled.

Here is the short version by model:

• You as merchant of record: you refund, you fulfill, you answer disputes.
• Third-party merchant of record: that party may carry those duties, per its contract.
• Payfac setup: the sub-merchant usually keeps fulfillment and refund duties.
• Processor setup: the processor moves money while you still refund and fulfill.

No — the processing model does not decide which financing providers you can add or whether you qualify. Availability depends on your industry, ticket size and each provider's underwriting outcome, not on whether you sit in a payfac or merchant-of-record structure. The provider sets its own rules and applies them to your business directly.

What does matter is your own provider agreement, which you sign with each financing provider under your own merchant accounts. Affirm, Klarna and SplitIt each decide applications and terms on their own. SplitIt uses existing card credit and leaves normal card risk with the merchant; keep that distinction in every funding discussion. Each provider publishes its own posture, so read each agreement on its own.

PayFull helps you offer these options inside your own checkout. The decision on any buyer still stays with the provider, because PayFull has no authority, control or influence over a provider's decision and does not underwrite. The model you run changes none of that.

Worked example: plan arithmetic for a financed sale

Suppose a business sells a program priced at $6,000. The buyer pays a deposit of $1,200 at checkout, which leaves a remaining balance of $4,800. That balance then splits into 4 installments of $1,200 each.

The schedule runs on day counts from the purchase date: the first installment is due at 30 days, the second at 60 days, the third at 90 days, and the last at 120 days. The deposit plus the four installments add up to the $6,000 price. This example is hypothetical, and it names no provider on purpose — the numbers only show how a plan splits a price into dated parts.

Before adding financing, confirm three things: your model, your merchant accounts and your provider agreements. These decide who the buyer sees as the seller and who owes the refund once a plan is in play. Check them first, so the financing layer sits cleanly on top of a structure you understand.

Work through this quick checklist:

• Your role: Are you the merchant of record, a sub-merchant under a payfac, or a direct merchant? Read your contract to confirm.
• Your accounts: Which merchant accounts are used, and are they yours? You keep your own accounts across every model.
• Your provider agreements: What does each financing provider require, and what happens when it changes its terms or availability?
• Your refund and dispute flow: Where do refunds and disputes land today, and who answers them?

One honest caveat belongs here: we can't promise a bank will never change its mind, and provider agreements can change or end. Treat each agreement as live, and revisit it when terms shift. This is general education, not legal advice, so confirm specifics with your own counsel.
