A failed payment usually isn't a lost one. In Adfin's data, 97% of direct debits are collected first time and 98.7% are collected in the end. Most failures are mechanical, such as low funds on the day, changed bank details or a cancelled mandate, so check the reason, retry, offer another way to pay, and only then make it a conversation.

The short version
- Most failed payments are mechanical: low funds, changed details or a cancelled mandate.
- In Adfin's data, 97% of direct debits succeed first time and 98.7% are collected in the end.
- Read the reason code, retry, offer another way to pay, then involve a person.
- Advance notice, current mandates and a second method on file prevent most failures.
- Adfin retries for free and charges nothing for a failed payment.
Why payments fail
It's tempting to read a failed payment as a sign of something about your customer. Most of the time the cause is duller than that.
| Reason | What's happened | What fixes it |
|---|---|---|
| Insufficient funds | The money wasn't there on the day | A retry |
| Account changed or closed | The mandate points at an old account | New details and a new mandate |
| Mandate cancelled | The customer cancelled it at their bank, sometimes long ago | Ask what happened, then set up a new one |
| Card declined or expired | A limit, a block or out-of-date details | Updated details or another method |
| Genuine dispute | The customer doesn't accept the charge | A conversation, not a retry |
Apart from a dispute, none of these says anything about whether your customer wants to pay. Treating one as a decision by your customer can turn a routine failure into an awkward call.
When a direct debit fails, the bank sends back a reason code through Bacs telling you which row you're in. Check it before you do anything, because the right response depends on it. Retrying a payment against a cancelled mandate won't work, and asking for new bank details won't help someone who was simply short that week.
What happens after a failure
Adfin's payment data shows how often a failed direct debit comes good. Of collections at least four weeks old, 97% succeeded on the first attempt and 98.7% were collected in the end. Of the direct debits that failed at least once, about six in ten were still collected.
Each retry is less likely to work than the one before. A second attempt succeeded 47% of the time and a third about a quarter of the time. By the third failure, something has usually changed for that customer, and a conversation or a different payment method is likely to do more than another retry.
Failures don't seem to come down to invoice size, either. Larger collections fail no more often than small ones, though a customer about to be debited a large amount will appreciate a heads-up.
How to handle a failed payment
It helps to work through these in order.
- Read the reason code. It tells you whether to retry, ask for new details, or deal with a dispute.
- Retry, unless the reason says the mandate or account no longer works. Low funds on the 1st are often fine by the 5th.
- Offer another way to pay. A payment link by card or pay by bank will often clear the same invoice the same day.
- Then bring in a person. By this point the mechanical failures have mostly cleared, so the calls you make are the ones that need making.
- Fix the cause. A stale account or cancelled mandate will fail again next month if you only collected this month's payment another way.
- Watch for patterns. One failure tells you little, but three on the same account usually points to the customer's cash position, which is worth a conversation.
Adfin does most of this without you. It retries failed direct debits for free, then asks the customer to pay another way. It doesn't charge you anything for a failed payment, so a failure costs you time at most. Its collection agents can then follow up over email, SMS or WhatsApp within rules you set, and offer an instalment plan where you allow one.
How to stop payments failing in the first place
Most of what keeps your failure rate down happens before the collection date.
- Tell customers before you collect. The direct debit rules require advance notice anyway, and a few working days gives them time to make sure the money's there.
- Collect on a date they expect. Failures are more likely when the date comes as a surprise, so line collection dates up with when your customers are paid or when they'd expect your invoice.
- Keep mandates current. A mandate set up years ago against an account that's since changed is likely to fail the next time you collect against it.
- Have a second method on file while things are calm, so a failure has somewhere to go.
- Avoid charging customers for a failed payment if you can. A fee can turn a mechanical problem into a dispute you then have to handle.
Common questions
Why did my direct debit payment fail? Usually insufficient funds, changed or closed bank details, or a mandate the customer cancelled at their bank. The reason code that comes back with the failure tells you which.
Do failed payments usually get recovered? Mostly, yes. In Adfin's data, 98.7% of direct debits are collected in the end, and about six in ten that fail once are still collected.
Should I retry a failed direct debit? Usually, unless the reason code says the mandate or account is no longer valid. A second attempt succeeds about half the time.
Do providers charge for failed direct debits? Some charge their fee on every payment they submit, whether it succeeds or not. Adfin doesn't charge for failed payments or retries.
What happens if a customer cancels their mandate? Collections stop. It's often not a dispute, just something done at the bank and forgotten, so ask before you escalate.
How do I stop payments failing in the first place? Give advance notice, collect on a date the customer expects, keep mandate details current and have a second payment method set up.
