You invoice on net 30. The customer pays at day 58, then day 61, then day 59. Every month, like clockwork. They never dispute anything, they always pay in full, and they always pay a month late.
That pattern is common, and it is getting more common. Atradius reports that 43% of credit-based B2B sales in the US are overdue, and 35% of US businesses say customer payment behavior has gotten worse (Atradius Payment Practices Barometer, US 2025). The Hackett Group found that DSO at the 1,000 largest US public nonfinancial companies worsened for a second straight year (The Hackett Group 2025 Working Capital Survey).
This guide is for the controller or AR manager whose team is chasing the same accounts every month. It answers one question: when customers keep paying 60 days late on 30-day terms, how do you fix it for good?
How Do You Stop Customers From Paying 60 Days Late?
You stop a chronic 60-day payer by finding out which cause is at work, fixing that cause, and then holding the account to its terms the same way every month. A one-off late payment is an event. A customer who pays 30 days late every cycle is running a process, and you have to change the process.
In practice, almost every chronic 60-day payer falls into one of five causes:
Cause | What it looks like | The fix |
|---|---|---|
Their AP cycle | Payments land on the same weekday or the same point in the month, always late | Learn their payment run and invoice into it |
Invoice approval lag | The invoice sits with an approver before AP will pay | Get the approver's name and confirm approval before the due date |
Missing invoice data | PO number, receiving document or contact is wrong, so the invoice waits | Fix the invoice template and billing contact |
Deliberate stretching | Payment is always full, always late, and the customer pays other priorities first | Reset terms in writing and tie shipments or work to the aging |
Real cash strain | Payments get later over time, or start arriving in pieces | Agree a written plan and reduce exposure |
The first three are process problems. They are the most common and the easiest to fix. The last two are business problems, and they need a firmer conversation.
Why Do Customers Settle Into Paying 60 Days Late?
Customers pay at 60 days because nothing happens to them at 31, 45 or 59. If your first real contact comes after the invoice is already 30 days past due, the customer's AP team learns that your terms are effectively net 60.
Your silence sets the real terms
Most AR teams send a reminder or two by email and save calls for large balances. A mid-sized account that always pays eventually never gets called, so it never changes. The terms on the invoice say 30. Your follow-up says 60.
Their AP team pays on its own calendar
Many companies pay suppliers in weekly or twice-monthly payment runs, and an invoice must be fully approved before the run that picks it up. Miss the cutoff by a day and the payment slips to the next run. Add a slow approval and 30 days becomes 60 without anyone deciding it.
Being late carries no cost
If shipments, service and support carry on exactly the same at 60 days as at 20, a customer under cash pressure will pay you later than suppliers who stop shipping. That is a rational choice on their side, and it is the habit you need to break.
For the psychology behind this, see our guide to the top excuses for late payments and how to handle each one.
Step 1: Pull the Payment History and Find the Pattern
Before you talk to the customer, look at the last six to twelve months of payments on the account. The pattern usually tells you the cause.
What to look for
Days to pay on each invoice, not only the average. A steady 58 to 62 means a process. A number that keeps rising means strain.
The weekday or date payments arrive. Payments that always land on the same weekday point to a weekly payment run.
Partial or short payments. These usually mean a dispute or a credit the customer believes they are owed.
Which invoices pay faster. If some invoices pay at 35 days and others at 65, compare them. The slow ones often lack a PO number or went to the wrong contact.
A quick test for deliberate stretching
If every invoice is paid in full, with no disputes and no questions, at a consistent 25 to 35 days past terms, the customer is most likely choosing to pay you late. Treat that differently from an account with approval or data problems.
Our guide on how to handle delayed payments from customers covers how to diagnose a single delayed invoice in more detail.
Step 2: Fix the Process Causes First
Most chronic late payers are not refusing to pay on time. Their system is not set up to pay you on time. Fixing that is fast, and it costs you nothing in the relationship.
Learn their payment run
Ask the customer's AP contact one direct question: "When is your payment run, and what is the cutoff for an invoice to be included?" Then work backward. If they pay on the second and fourth Friday, an invoice that is approved and in their system a few days before the due date will be paid on time.
Get approval before the due date
Ask who approves your invoices and confirm with that person, by name, that the invoice is approved about 10 days before it is due. An invoice that is still sitting with an approver on day 30 will be paid at day 60.
Fix the invoice data
Check every invoice for the details the customer's AP team needs to match and pay:
The customer's PO number, in the field they use
The correct bill-to entity and remit-to details
The receiving document or proof of delivery, if their process requires it
The right AP email address, portal or delivery method
Bad contact data alone can add weeks. Our guide to AR billing contact data covers how to keep it clean.
If the customer is holding an invoice over a quantity, rate or credit question, resolve that first. Our guide on how to resolve invoice disputes walks through it.
Step 3: Change When and How You Follow Up
The single biggest lever on a chronic late payer is contact before the due date, not after it. Move your follow-up earlier and make it consistent.
A cadence for 30-day terms
Day | Action | Purpose |
|---|---|---|
Invoice day | Invoice sent with PO number and correct contact | Start the clock cleanly |
Day 20 | Confirm receipt and approval with AP or the approver | Catch problems while there is time to fix them |
Day 28 | Short reminder that payment is due on day 30, confirming the payment run date | Get onto the right payment run |
Day 31 | Call or message: payment is due, when will it be sent? | Make lateness visible the first day |
Day 38 | Call with a specific request: a date and an amount | Get a commitment |
Day 45 | Escalate to the account owner and the customer's controller | Raise the stakes before 60 |
The detail of each touch is in our guide to mapping the ideal follow-up cadence after the due date.
Ask for a date, then hold them to it
"Can you check on this?" gets a vague answer. "Can you confirm this will be in Friday's payment run?" gets a yes or a no. When the customer gives a date, log it and follow up the day after if the money has not arrived. Our guide to promise-to-pay tracking shows how to make those commitments stick.
Cover every account, every week
Chronic 60-day payers are usually mid-sized accounts that never reach the top of the call list. If your collectors spend their week on the ten largest balances, the next fifty accounts hear only automated emails. Coverage, not effort, is usually what is missing.
Step 4: Reset the Account When It Is Deliberate Stretching
When the payment history shows a customer choosing to pay you late, you need one clear conversation and then consistent follow-through. The goal is not to punish the customer. It is to make your terms real.
Have the terms conversation
Talk to the customer's controller or owner, not only AP. Keep it short and factual:
Show the payment history: "Over the last eight months, invoices on 30-day terms have paid at an average of 59 days."
Ask directly: "Is there something on our side that is slowing payment down?"
State the expectation: "Going forward, we need payment within terms."
Agree the next step and confirm it in writing.
Decide what changes if it continues
Before the conversation, agree internally what happens if the pattern continues. Common options:
Shorter terms or a lower credit limit for that account
Shipment or work holds once invoices pass an agreed number of days past due
Deposits or progress billing on new orders
Terms that match reality, built into the account by your sales team, if the customer truly needs 60 days
Whatever you choose, write it down and apply it the same way every time. Our guide to setting a credit hold policy covers how to agree the rule with sales. Most accounting systems support it directly: Microsoft Dynamics 365 Business Central, for example, can block a customer for shipping, invoicing or all transactions (Microsoft Learn: block customers).
If you are weighing whether to change terms at all, our guide to net 30, 60 and 90 payment terms and DSO explains the trade-offs.
Step 5: Handle Real Cash Strain Differently
A customer whose payments are getting later every month is a credit risk, not a habit problem. Treat it as one.
Warning signs
Days to pay rising month over month
Partial payments without a dispute
A new AP contact who cannot give dates
Requests to delay that come with no specific reason
What to do
Talk to the decision maker early, agree a written payment plan for the past-due balance, and reduce new exposure until the plan is working. Our guide to setting up a payment plan for a past-due B2B customer covers the structure.
What Results Should You Expect?
Fixing process causes usually shows up within one or two billing cycles. Once invoices are approved and in the right payment run, the account often moves from 60 days to close to terms without a difficult conversation.
Deliberate stretching takes longer. Expect the first month after the terms conversation to improve, and the account to test you again within a few months. Consistency is what holds the gain.
Track three numbers per account: average days to pay, the share of invoices paid within terms, and the number of follow-up touches before payment. If those improve across your chronic late payers, your DSO will follow.
Where Does Abivo Fit?
Abivo gives an AR team Kate, an AI collections agent that follows up on every open invoice by phone, text and email, inside your accounting system. Kate confirms receipt and approval before the due date, asks for specific payment dates, logs promises to pay and follows up the day after a missed one, and routes disputes and missing invoice data to the right person on your team.
That closes the coverage gap that lets mid-sized accounts settle into paying at 60 days, while your collectors keep the terms conversations and key accounts. One customer, OFS, recovered $842,518 in four months, cut DSO by more than 30 days, and went from four collectors to one (read the OFS case study). You can also see Kate on a live call.

Follow up before the due date, not after it, and ask for a specific date.
Have one clear terms conversation with the controller when lateness is deliberate.
Write down what changes if it continues and apply it the same way every time.
Cover every account every week, not only the largest balances.
Frequently Asked Questions
Why do customers pay 60 days late on net 30 terms?
Usually because of their payment process: invoices miss the approval or payment-run cutoff, or lack a PO number. Some customers also stretch payment deliberately when being late has no consequence. The payment history usually shows which.
When should I first contact a customer who always pays late?
Before the due date. A check around day 20 to confirm the invoice is received and approved, and a reminder before day 30 that confirms which payment run will include it, does more than any reminder sent after the invoice is overdue.
Should I just change the customer's terms to net 60?
Only if you decide the account is worth carrying for 60 days and your sales team builds that into the account. Changing terms to match a habit without that decision simply lengthens your DSO.
How do I ask a customer to pay on time without damaging the relationship?
Keep it factual. Show the payment history, ask whether anything on your side is slowing payment down, state the expectation clearly, and confirm the agreement in writing.
Can AI help with customers who always pay late?
Yes. An AI collections agent can contact every account before and after the due date, confirm approval, ask for payment dates and log promises to pay, which is the consistent follow-up that breaks the 60-day habit.
