How to Set Up a Payment Plan for a Past-Due B2B Customer
When a good customer cannot pay an overdue balance in one go, a short written payment plan beats months of silence. How AR teams decide when to offer one, set the schedule, record it and track every installment.

Every AR team has a few accounts like this: a customer you want to keep, a balance that is well past due, and a contact who says they want to pay but cannot clear it all at once. Left alone, that balance ages into the 90+ bucket while both sides avoid the conversation.
It is a common situation. Atradius reports that 43% of credit-based B2B sales in the US are overdue, primarily because of customer cash flow pressure (Atradius Payment Practices Barometer, US 2025). When cash flow is the real reason, repeating "please pay the full balance" rarely works. A short, written payment plan often does.
This guide is for the controller or AR manager who has to decide when a payment plan makes sense, how to set one up so it actually gets paid, and how to keep it from quietly turning into another overdue balance.
What Is a Payment Plan in B2B Collections?
A B2B payment plan is a written schedule that splits an overdue balance into dated installments the customer commits to pay. It replaces one large past-due amount that is not getting paid with several smaller amounts that can be.
A good plan has four parts:
The balance it covers, by invoice number.
The installment amounts and dates, usually weekly or every two weeks.
The account status while the plan runs, for example new orders on prepayment or a reduced credit limit.
What happens if an installment is missed, written down before the first payment.
A payment plan is different from a promise to pay. A promise covers one amount on one date. A plan is a series of promises with a defined end, and it needs to be tracked as a series, not as one note in the customer record. For single promises, see our guide to promise-to-pay tracking.
When Should You Offer a Payment Plan?
Offer a payment plan when the customer agrees the balance is owed, wants to keep buying from you, and has a real cash flow reason for not paying in full. All three need to be true.
Signs a payment plan is the right tool
The balance is undisputed. The customer is not contesting amounts, quantities or delivery.
The customer is talking to you. They answer calls and give you specific information about their situation.
The cause is timing, not willingness. A delayed payment from their own customer, a slow season, or a large one-off expense.
The account has value. A long history, steady volume or strategic importance makes a structured recovery worth more than a hard stop.
When a payment plan is the wrong tool
There is an open dispute. Resolve it first. A plan built on a disputed balance gets broken the moment the dispute resurfaces. Our guide on how to resolve invoice disputes covers that process.
The customer has gone silent. A plan needs a counterpart. Silence calls for your escalation path, covered in when to escalate an invoice.
Previous promises were broken without explanation. A plan is a bigger promise. If small ones have failed, start with a smaller test payment.
Payment plan vs other collection options
Situation | Best tool | Why |
|---|---|---|
Customer can pay in full within days | Promise to pay | One date, one amount, no schedule needed |
Undisputed balance, real cash flow issue, customer engaged | Payment plan | Gets cash moving now and keeps the account |
Customer keeps ordering while old invoices age | Credit hold, then plan | Stops the balance from growing first |
Balance is disputed | Dispute resolution | A plan on a contested amount will break |
No response after repeated follow-up | Escalation | A plan needs a customer willing to engage |
How Do You Set Up a Payment Plan? 6 Steps
Confirm the balance, get the customer's own numbers, set a short schedule, tie it to the account status, put it in writing and record it in your accounting system. Each step closes a gap that commonly breaks plans later.
1. Confirm the exact balance
Send the customer a list of every open invoice the plan will cover, with invoice number, date and amount. Ask them to confirm it matches their records. Unapplied payments, credits and short-pays are the usual reasons the numbers differ, and it is much easier to fix them now than after the second installment.
2. Ask what the customer can pay, and when
Ask the customer to propose an amount and a date for the first payment, and to tell you when their cash position improves. Their own numbers are more likely to be paid than a schedule you impose. Then test the proposal against what you know about the account: their usual payment size, their own billing cycle, and any seasonality.
3. Keep the schedule short and front-loaded
Aim for a first payment within days and a plan that ends within a few months. A meaningful first payment shows commitment and reduces your exposure right away. Weekly or biweekly installments keep the plan visible on both sides; monthly installments leave long gaps where things drift.
4. Tie the plan to the account status
Decide what happens to new orders while the plan runs. Common options are prepayment or cash on delivery for new orders, a reduced credit limit, or normal terms only after a set number of installments are paid on time. Our credit hold policy guide covers how to set and lift holds without surprising sales.
5. Put it in writing
Send a short confirmation email that the customer replies to. It should list the invoices covered, every installment amount and date, how they will pay, the account status while the plan runs, and what happens if a payment is missed. A plan agreed only on a phone call is remembered differently by each side within weeks.
6. Record it where your team works
If the plan lives only in one collector's inbox, it disappears when that collector is out. Record it in your accounting system or AR tool so every installment shows up as a dated expectation. The next section covers how that works in common systems.
What Should a Payment Plan Confirmation Include?
Use this checklist for the written summary:
Customer name, contact and the person who approved the plan on their side.
Invoices covered, with numbers, dates and the total balance.
Installment schedule: amount and date for every payment.
Payment method and remittance details, including the invoice numbers to reference.
Account status during the plan, such as prepayment for new orders.
Missed-payment step: for example, the plan pauses and the remaining balance returns to your normal collections process.
Your contact for questions, so they reach a person before a due date, not after it.
Keep it to one page. The goal is a shared record both teams can check, not a long document that sits unread.
How Do You Record a Payment Plan in Your Accounting System?
Record each installment as its own dated amount, so your aging report and your collectors see exactly what is due and when. How you do that depends on the system.
NetSuite
NetSuite has an Installments feature. Once enabled, you define an installment term with a recurrence frequency and a recurrence count, and either split the amount evenly or enter each installment by hand. On an invoice, Override Installments lets you change an existing schedule as long as the total still matches. Oracle's documentation also notes that only the late installment is marked past due in aging, not the entire invoice (NetSuite Help, Creating Installments). That keeps the aging report honest while a plan is running. To review the result, see our guide to exporting an AR aging report from NetSuite.
QuickBooks Online
QuickBooks Online does not split an existing invoice into installments, but it handles partial payments. Intuit's help article says to record payments even when you were paid only part of what is owed, and that QuickBooks keeps track of the remaining invoice balance (QuickBooks, Record invoice payments). Track the schedule itself alongside it, as dated promises in your AR process.
Any other system
If your system has no installment feature, record each installment as a dated promise to pay against the account, with the amount and the plan reference. The aging report will still show the full invoice as overdue, so your team needs the promise list to know which accounts are on a plan and current.
A Worked Example (Illustrative)
A distributor's customer owes $48,000 across four invoices, all 45 to 75 days past due. The customer confirms the balance, explains that a large project payment of their own is late, and proposes a plan. The AR manager agrees to this schedule, with new orders on prepayment until the third installment clears:
Installment | Date | Amount | Remaining balance |
|---|---|---|---|
1 | Week 1 | $12,000 | $36,000 |
2 | Week 3 | $12,000 | $24,000 |
3 | Week 5 | $12,000 | $12,000 |
4 | Week 7 | $12,000 | $0 |
The figures are an example, not a benchmark. The structure is what matters: $12,000 up front, two-week spacing, a seven-week end date and a clear account status while the plan runs.
How Do You Track a Payment Plan So It Actually Gets Paid?
Treat every installment as a due date that gets a reminder before it, a check on the day, and a follow-up the day after if nothing arrived. Most broken plans are not refusals. They are installments that slipped because no one on either side was watching the date.
Before each installment
Send a short reminder a few days ahead with the amount, the date and the invoice references. It gives the customer's AP team time to schedule the payment.
On the due date
Check whether the payment arrived and was applied to the right invoices. Apply it the same day so the remaining balance is correct before the next reminder goes out.
When an installment is missed
Contact the customer the next business day. Ask what happened and whether a new date is realistic within days. One slip with a clear reason can be absorbed; a second missed installment usually means the plan should end and the remaining balance should go back into your normal escalation path. For the conversation itself, our guide on how to handle delayed payments from customers has practical scripts.
Common Payment Plan Mistakes
Plans that run too long. A balance spread over many months stays at risk for many months.
No first payment. A plan that starts in a month is a delay, not a plan.
Open orders on normal terms. The old balance shrinks while a new one grows.
Nothing in writing. Each side remembers different dates.
Tracking in one person's inbox. The plan fails the week that person is on vacation.
No missed-payment step. Without one, a missed installment turns into a renegotiation instead of a decision.
Where Does an AI Collections Agent Help?
Your team sets the terms of a payment plan; that is a judgment call on a valued account. The work that breaks plans is the follow-up around it, and that is where Abivo's AI collections agent, Kate, helps:
Every overdue account gets followed up by phone, text and email, so accounts on a plan and accounts not yet on one both get attention every week.
Promises to pay are recorded with date and amount, so each installment the customer commits to is visible to the whole team.
Disputes are logged and handed to your team, which keeps disputed balances out of plans until they are resolved.
One message can cover all open invoices on an account, with the invoice details the customer's AP team needs to schedule payment.
OFS Group went from four collectors to one with Abivo, recovered $842,518 in four months and cut DSO by more than 30 days; the full story is in the OFS Group case study.
Practical Takeaways for AR Managers
Offer a plan only on an undisputed balance with a customer who is engaged and has a timing problem.
Ask for the customer's numbers first, then test them against their history.
Front-load and keep it short: a first payment within days and an end date within a few months.
Set the account status for new orders before the first installment.
Confirm it in writing and record every installment as a dated amount in your system.
Follow up before, on and after each installment date, and decide in advance what a missed payment means.

Frequently Asked Questions
What is a payment plan for an overdue invoice?
It is a written schedule that splits an overdue balance into smaller, dated installments that the customer commits to pay. It lists the invoices covered, each installment amount and date, the account status while the plan runs and what happens if a payment is missed.
When should a business offer a customer a payment plan?
When the balance is undisputed, the customer is engaged and wants to keep buying, and the reason for not paying in full is cash flow timing. If the balance is disputed or the customer has stopped responding, resolve the dispute or escalate instead.
How long should a B2B payment plan last?
As short as the customer can realistically manage, with a first payment within days. Many AR teams aim to finish within a few months, using weekly or biweekly installments so the plan stays visible on both sides.
Should a customer on a payment plan keep ordering on credit?
Usually not on normal terms. Common approaches are prepayment for new orders, a reduced credit limit, or normal terms only after a set number of installments are paid on time.
What happens if a customer misses a payment plan installment?
Contact them the next business day and ask for a new date within days. If a second installment is missed, most teams end the plan and return the remaining balance to their normal escalation process, as stated in the written plan.
