Offering payment plans means letting customers pay you over time instead of all at once
A payment plan is an agreement where a customer owes you money and pays it back in installments over weeks or months. You decide the terms: how many payments, how much each one is, when they're due, and what happens if someone misses a payment. The customer gets to spread the cost, and you get paid in full (or mostly full) instead of losing the sale because someone couldn't pay upfront.
You can offer payment plans directly to your customers without a third party, or you can use a payment processor or lending partner to handle the installments for you. The method you choose depends on your business size, how much risk you want to carry, and what your customers expect.
Key Takeaways
- You can collect payments yourself through invoices and reminders, or use a payment processor that handles installments automatically and takes on some of the risk.
- Payment processors like Affirm, Klarna, and Sezzle let customers pay in installments at checkout, and they pay you upfront minus a fee.
- If you collect payments yourself, you need a system to track who owes what, send reminders before due dates, and handle late or missed payments.
- Setting clear terms in writing—number of payments, due dates, late fees, and what happens if someone defaults—protects both you and the customer.
- Payment plans work best for purchases over $100 to $200, where the customer benefits from spreading the cost but the amount is large enough to justify the paperwork.
Decide whether to use a third-party processor or collect payments yourself
If you use a third-party payment processor, the customer chooses to pay in installments at checkout, the processor approves them (or declines them), and the processor pays you the full amount immediately minus a fee—usually 2 to 8 percent depending on the provider and the payment method. You never chase the customer for money; the processor does. This is simpler for you but costs more per transaction.
If you collect payments yourself, you send the customer an invoice or payment link, they send you money on the schedule you agreed to, and you track the payments in a spreadsheet or accounting software. You keep all the money (minus payment processing fees for each transaction), but you handle reminders, follow-up, and the risk that someone stops paying. This works if you have a small number of payment plans or if your customers are businesses you trust.
Most retailers use a processor because it's faster to set up, requires less follow-up, and shifts the risk of non-payment. Most service businesses and contractors collect payments themselves because they have fewer transactions and know their customers personally.
Popular payment processors for installment plans
Affirm lets customers split purchases into 3, 6, or 12 monthly payments at checkout. Affirm approves or declines each customer based on their own credit check. You get paid immediately, minus Affirm's fee. Affirm handles all collection and reminders. You integrate Affirm into your website or point-of-sale system.
Klarna offers "buy now, pay later" in 4 interest-free payments over 6 weeks, or longer installment plans. Klarna also pays you upfront. Klarna is popular in fashion and home goods retail.
Sezzle splits purchases into 4 payments over 6 weeks, interest-free. Sezzle charges you a fee per transaction and pays you within 24 hours.
PayPal Credit and Square Installments let customers finance purchases through your existing payment processor if you already use PayPal or Square. The setup is simpler because you don't add a new tool.
Bread and Upgrade focus on larger purchases—furniture, appliances, home improvement—and offer longer terms, sometimes up to 60 months.
Each processor has different fees, approval rates, and customer bases. Compare them based on your average order size, your industry, and which ones your customers already use.
Set up terms in writing before the first payment
Whether you use a processor or collect yourself, write down the payment plan terms and have the customer sign or confirm them before they make the first payment. Include:
- The total amount owed
- The number of payments and the amount of each payment
- The due date for each payment (for example, the 1st of each month, or 14 days after invoice)
- The payment method (bank transfer, credit card, check, online payment link)
- What happens if a payment is late (a late fee, a percentage charge, or a reminder with no penalty)
- What happens if the customer stops paying (you stop providing the service, you refer the debt to a collection agency, you pursue legal action)
- Whether the plan can be canceled early and what that means
If you're collecting payments yourself, send this in an email or a simple one-page document. If you use a processor, the processor's terms cover most of this, but you should still confirm the payment schedule with the customer so there's no confusion.
Track payments and send reminders
If you're using a processor, they handle tracking and reminders automatically. If you're collecting payments yourself, you need a system.
Use a spreadsheet or accounting software (QuickBooks, FreshBooks, Wave) to record each customer's name, total amount owed, payment schedule, and which payments have been received. Mark each payment as it arrives. This takes 5 minutes per customer per month but prevents you from losing track of who owes what.
Send a reminder email 3 to 5 days before each payment is due. Keep it simple: "Your payment of $150 is due on March 1st. You can pay here [link]. Let me know if you have questions." A friendly reminder before the due date stops most late payments before they happen.
If a payment is late, send a follow-up email within 3 to 5 days asking what happened and whether they need to reschedule. Most late payments are honest mistakes or temporary cash flow problems, not refusals to pay. A quick conversation often resolves it.
Decide how to handle late or missed payments
A late fee is a fixed amount you charge if a payment arrives after the due date—for example, $25 or $50. A late charge is a percentage of the payment, usually 1 to 5 percent per month. Check your state's laws; some states cap how much you can charge for a late payment, and some require you to disclose the fee in writing before the customer agrees to the plan.
If a customer misses a payment, you have options: you can charge a late fee and give them a grace period (usually 10 to 15 days) to pay, you can pause the plan and reschedule the remaining payments, or you can declare the plan in default and demand full payment immediately. Which you choose depends on your relationship with the customer and how much money is at stake.
If a customer stops paying and won't respond to reminders, you can refer the debt to a collection agency, which will pursue payment on your behalf for a cut of what they collect (usually 25 to 50 percent). For small amounts under $500, collection agencies often won't take the case because it's not worth their time. For larger amounts, a collection agency can be effective.
Document everything: save emails, record payment dates, and note any conversations about late payments. If you end up in a dispute or small claims court, this record proves what you agreed to and what the customer paid.
Decide whether to offer payment plans on all purchases or only some
Payment plans make sense for larger purchases where the customer benefits from spreading the cost. For a $50 item, the customer probably won't want to pay in installments. For a $500 or $2,000 purchase, they might.
You can set a minimum purchase amount—for example, "payment plans available on orders over $200"—to keep the paperwork manageable. You can also limit payment plans to certain products or services. A furniture store might offer 12-month plans, while a clothing retailer might offer 4-payment plans only.
If you use a processor, they usually set the minimum and the terms, so you have less control. If you collect payments yourself, you decide.
Frequently Asked Questions
What if a customer wants to pay off the plan early?
Most payment plans allow early payoff with no penalty. Decide this before the customer signs up and include it in your terms. If you're using a processor, check their policy—most allow it. If you're collecting yourself, early payoff is usually fine because you get paid sooner.
Do I need a license or special permission to offer payment plans?
If you're offering payment plans directly (not through a processor), you're not lending money or charging interest, so you don't need a lending license in most states. If you charge interest or late fees, check your state's consumer protection laws. If you use a processor like Affirm or Klarna, they handle licensing and compliance.
What if a customer disputes a payment or says they didn't authorize it?
If the payment went through a credit card or online payment processor, the customer can dispute it with their bank or card issuer, and you'll have to prove the charge was authorized. This is why written terms and confirmation emails matter—they show the customer agreed. Keep records of all communications.
Can I charge interest on a payment plan?
Yes, but state laws vary on how much interest you can charge and what disclosures you must make. Some states cap interest rates; others require you to disclose the annual percentage rate (APR) in writing before the customer agrees. Check your state's consumer protection laws or talk to a lawyer if you plan to charge interest.
What's the difference between a payment plan and a loan?
A payment plan is an agreement to pay for something you've already received over time. A loan is money you borrow and then repay with interest. If you're not charging interest and the customer gets the product or service upfront, it's a payment plan. If you're charging interest or the customer doesn't get anything until they've paid in full, it's closer to a loan and may require licensing.
