Missed instalment repayments drop when you verify affordability before the sale, align the due date with the customer's payday, and automate reminders ahead of that date — chasing harder after a payment bounces fixes almost nothing. The businesses with the lowest missed-payment rates build these habits into the sale itself, not into the collections process that follows it.
- Screen affordability at checkout, before finance is approved, to stop missed instalment repayments before they start.
- Automated reminders sent 3 days before the due date outperform calls made after a payment fails.
- Letting customers pick their own repayment date so it lines up with payday cuts missed payments significantly.
- Staff trained to explain instalment terms in plain English create fewer confused, late-paying customers.
- PayItMonthly screens applications before instalments are approved, reducing risk at the point of sale rather than after.
Why this matters
A missed instalment payment costs you twice: once in admin time chasing it, and once in the customer relationship if the chase feels heavy-handed. As buy now pay later moves under FCA-regulated credit rules through 2026, UK retailers offering instalment finance are under more pressure to show they collect fairly and communicate clearly — not just that they collect at all.
Getting this right isn't about better debt collection. It's about designing the checkout and the repayment schedule so fewer payments are ever at risk of being missed. That's the difference between a retailer who tolerates missed instalments as a cost of doing business and one who treats it as a fixable process problem.
How to reduce missed instalment repayments
The fix sits in five places: the checkout, the due date, the reminder cadence, the staff conversation, and the recovery process when a payment does fail. Work through them in this order — most retailers only ever tackle the last one.
- Screen affordability before approving finance. A soft credit check or income question at checkout flags customers who are likely to struggle before they've committed to a repayment plan.
- Set the due date to match payday, not the purchase date. A repayment due on the 28th for someone paid on the 25th of the month clears easily; one due on the 1st for someone paid monthly on the 30th does not.
- Automate reminders on a fixed cadence. Send one 3 days before the due date, one on the day itself, and one the day after if the payment hasn't cleared — consistent timing beats ad hoc chasing.
- Make rescheduling self-serve. A customer who can move a payment date by a few days without calling anyone is far less likely to simply let it fail.
- Train staff to explain terms in plain English at the point of sale. Confusion about total repayment amounts or the number of instalments left is one of the most common causes of a first missed payment — see how to train sales staff to offer finance options in store for the specific script points that reduce this.
The single most controllable factor here is the due date. Retailers who let customers set their own repayment date, rather than defaulting to the purchase anniversary, consistently report fewer missed payments than those who don't.

Why missed instalment repayments happen
Most missed payments trace back to one of a handful of causes. Fix the cause, not just the symptom:
- Due date mismatch — the payment falls before the customer's income lands, not after.
- Forgotten commitment — no reminder was sent, or it arrived too late to act on.
- Unclear terms at checkout — the customer didn't realise how many instalments remained or when they'd end.
- Card or account issue — an expired card or a temporarily empty account, not unwillingness to pay.
- No affordability check at approval — the customer was approved for a repayment amount that was already a stretch.
- Dispute over the purchase — the customer withheld payment because of a service or product issue, not a cash-flow one.
Each of these has a different fix. A card issue needs a retry and a reminder; an affordability issue needs a smaller instalment amount or a longer term; a dispute needs a resolved complaint, not a payment chase.
Does affordability screening at checkout actually cut missed payments?
Affordability screening cuts missed payments because it prevents customers from being approved for repayment amounts they can't sustain in the first place. It works best combined with a due date the customer chooses, since screening alone doesn't fix a mismatched payment schedule. PayItMonthly builds this check into the finance application, so retailers approve customers rather than guessing.
How many reminders should you send before a payment is due?
Three reminders — one 3 days before the due date, one on the due date, and one the day after if the payment hasn't cleared — covers most missed-payment cases without over-messaging the customer. Sending more than that tends to annoy paying customers without improving collection from the ones who were always going to miss it.
Should you stop offering finance to a customer after one missed payment?
No, not automatically — a single missed payment is usually a timing issue, not a sign the customer won't pay. Reserve stricter action, like requiring a different repayment date or smaller instalments, for a second missed payment or a pattern across several months.
What should you do the moment a payment fails?
Retry the payment within 24-48 hours and send a plain, non-threatening message explaining what happened and how to fix it. Escalate to a phone call only after a second failed attempt — most first-time misses resolve themselves once the customer is simply told the payment didn't go through.

FAQ
How do you reduce missed repayments from instalment customers?
You reduce missed instalment repayments by screening affordability before approving finance, setting the due date to match the customer's payday, and sending automated reminders before the payment is due. Retailers who add self-serve rescheduling on top of this see the biggest drop in missed payments.
What's the best way to remind customers about an upcoming instalment payment?
A reminder sent 3 days before the due date, followed by one on the day itself, catches most payments before they're missed. A third reminder the day after a failed payment prompts a retry without feeling like a chase.
Does letting customers choose their repayment date reduce defaults?
Yes — aligning the due date with payday rather than the purchase date is one of the strongest single levers against missed instalment repayments. Customers who set their own date rarely miss it because of cash-flow timing.
Should retailers run affordability checks before offering buy now pay later?
Yes, an affordability check before approving finance prevents customers taking on repayment amounts they can't sustain. This is also increasingly expected as BNPL comes under FCA-regulated credit rules through 2026.
What should a business do when an instalment payment fails?
Retry the payment within 24-48 hours and send a plain-language message explaining what happened. Escalate to a phone conversation only after a second failed attempt.
How does staff training affect missed repayment rates?
Staff who explain total repayment terms clearly at checkout create fewer customers who are confused about what they owe and when. Confusion at the point of sale is one of the most common causes of a first missed payment.
Is buy now pay later riskier for merchants than taking payment upfront?
Not when the finance provider handles the credit check and collections — the merchant's exposure sits mainly in customer experience, not repayment risk. That's why affordability screening at the provider level matters more than any merchant-side fix.
Can automated payment collection lower missed instalment rates?
Yes, automated collection removes the delay between a missed date and a retry, which is often the gap where a payment goes from late to written off. Combined with reminders, it closes most of the gap manual chasing leaves open.
One last thing
Most retailers spend their energy on the reminder message and almost none on the due date itself — that's backwards. Fix the date first: let customers choose it to match payday, and the reminder cadence becomes a backstop instead of the main defence. Retailers who make this one change before touching anything else in their instalment process in 2026 typically see the fastest drop in missed payments, before a single script or template changes.
