How to Set Up a Payment Plan for a Customer Who Can't Pay

A customer who says "I can't pay it all right now" is not a customer who refuses to pay. That's a good sign, and a well-structured payment plan often gets you paid in full when the alternative is months of silence. This guide walks through when a plan makes sense, how to build one, what to put in writing, and how to keep it from falling apart.

When should I offer a payment plan instead of demanding full payment?

Offer a plan when the customer is honest about the problem and still willing to pay. Good signs:

• They replied to you, even if the news was bad.
• They acknowledge the invoice is correct and the work was done.
• They can name an amount they can afford, or at least a rough timeline.
• They have a real reason: a slow month, a delayed insurance payout, a client of their own who hasn't paid them.

Be more careful when the customer disputes the work, goes silent, or keeps making promises with no money behind them. A plan won't fix a dispute. For those situations, see what to do when a client refuses to pay an invoice or how to collect payment from a client who is ignoring you.

The math is simple: a smaller amount paid on a schedule beats a large amount that never arrives. Offering a plan also costs you almost nothing compared with the time spent chasing.

How do I set up a payment plan step by step?

1. Get the full picture first

Before proposing anything, confirm the exact balance owed, including any approved change orders, and check whether the customer has other open invoices. A plan should cover everything outstanding so you don't end up with a second, messier conversation later.

2. Ask what they can actually afford

Let the customer propose a number first. People commit harder to amounts they chose. If they suggest something unrealistically low, counter with a shorter timeline or a larger down payment rather than arguing about the monthly figure.

3. Ask for a down payment

Even 10 to 25 percent of the balance changes the dynamic. It proves good faith, reduces your exposure right away, and makes the remaining balance smaller and easier to schedule. If they can't give any down payment, ask for the first installment within a few days, not a few weeks.

4. Keep the plan short

The longer a plan runs, the more likely something goes wrong. For small invoices, two to four installments is usually enough. For larger balances, a few months is more realistic than a year. Set due dates that line up with when your customer gets paid (for example, the 1st and 15th, or right after their own billing cycle).

5. Choose how they'll pay

The easiest plans run on autopay. Ask the customer to authorize recurring card or ACH payments so each installment comes out on its due date without anyone remembering to send money. Get their clear, written authorization for any recurring debit. If you can't set up autopay, send a pay link before each due date.

6. Put it in writing

Every plan needs a short written agreement, even if it's an email the customer replies "agreed" to. See the next section for what to include.

7. Track it and follow up

Calendar every due date. Send a short reminder a few days before each installment and a thank-you after each one clears. A missed installment should get a response the next day, not the next month.

What should a payment plan agreement include?

A payment plan agreement doesn't need to be long. One page is plenty. Include:

• Parties and invoice reference: your business name, the customer's name, and the invoice number(s) being covered.
• Total balance: the exact amount owed.
• Down payment: the amount and date.
• Installment schedule: each amount and its due date.
• Payment method: card, ACH, or pay link, plus the customer's authorization if payments are automatic.
• Late or missed payment terms: what happens if an installment is more than a few days late.
• Acceleration clause: if the customer misses a payment and doesn't fix it within a stated number of days, the full remaining balance becomes due.
• Acknowledgment of the debt: a sentence confirming the customer agrees the amount owed is correct.
• Hold on further work or credit: you will not start new work or extend new credit until the plan is current or paid off.
• Signatures and dates: a typed name and an email confirmation or e-signature is generally how most small businesses handle it.

A few cautions. If you plan to add interest or a late fee to the plan, check your original contract and your state's rules first, since limits vary by state (see can I charge a late fee on an unpaid invoice). Many owners simply keep the plan interest-free to keep it simple and encourage completion. And because a signed acknowledgment of a debt can affect legal deadlines in some states, have an attorney review your template once if the balances are significant. This is general information, not legal advice.

What should I say to the customer? (Script)

Tone matters. You want the customer to feel you're solving the problem with them, not cornering them.

Email or text offering a plan:

Hi [Name], thanks for letting me know where things stand. I'd like to help make this manageable. Here's what I can offer for invoice #[number] ($[total]): - $[down payment] by [date] - Then $[amount] on [date], [date], and [date] We can set it up on autopay so you don't have to think about it. If you reply "agreed," I'll send a short written confirmation and the payment link. If these dates don't work, tell me what does and I'll see what I can adjust.

If the customer counters too low:

I want to make this work. At $[low amount] a month it would take [X] months, which is longer than I can carry. Could we do $[down payment] now and $[higher amount] a month for [shorter number] months? If cash is tight right now, even a smaller first payment this week would help.

What if the customer misses a payment on the plan?

Have the response ready before it happens.

1. Day 1 after a miss: send a friendly note with the pay link. Most misses are oversight or a failed card.
2. Day 3 to 5: follow up again, call if you can, and ask directly what happened. Offer a one-time adjustment if the reason is reasonable.
3. Past your grace period: invoke the acceleration clause you wrote into the agreement. Send a clear written notice that the full remaining balance is now due by a specific date.
4. If it still isn't resolved: move to a formal notice. Our guide on how to write a final notice before sending to collections covers the wording, and when to send an unpaid invoice to collections covers the timing.

One broken plan doesn't mean you were wrong to offer it. It means you now have a signed acknowledgment of the debt, a payment history, and a clear paper trail if you need to escalate.

Common mistakes to avoid

• Verbal-only agreements. If it isn't written, you'll disagree later about what was said.
• Plans that are too long. The further out the final payment, the lower the odds you'll see it.
• No down payment. Zero upfront often means zero follow-through.
• Continuing work while they owe you. Pause new work until the plan is current.
• Letting a missed payment slide. The first miss sets the pattern. Respond fast and calmly.
• Forgetting the reminders. Many plan failures are just forgotten due dates, which automated reminders solve.
• Writing off the rest informally. If you decide to settle for less than the balance, put that in writing too, as a settlement, so the terms are clear.

How Casey handles this for you

Offering payment plans is one of the things Casey does as part of following up on overdue invoices. Between 4 and 60 days past due, Casey reaches out on the channel and at the time each customer responds to, offers payment plans and partial payments, and keeps track of how each customer pays. Casey asks you before doing anything sensitive, and you can pause reminders for any customer. If an invoice reaches 60+ days past due, one tap sends it to Casey's collections team, which can arrange payment plans and settlements with your approval. Pricing is simple: $5 per invoice only if Casey has to chase it, and 20% of what's recovered in collections (nothing if nothing is recovered). See pricing.
