How to Chase Overdue Trade Invoices Without Losing the Customer (2026)
A calm, evidence-led overdue invoice workflow for UK trade businesses, from terms and reminders to disputes and escalation.
A late invoice does not need an aggressive first response. It needs a clean record of what was agreed, what was delivered, who received the invoice and whether anything is genuinely disputed. Once those facts are clear, the follow-up can stay firm, useful and proportionate.
How can you prevent avoidable delays before chasing?
Many late payments begin before the due date. The invoice goes to the site contact instead of accounts, the purchase order is missing, the customer cannot recognise the job, or the payment route is awkward. Check those basics before sending a stronger message.
Agree terms when the quote is accepted. Put the due date on the invoice, send it promptly after completion, and include enough job detail for the customer to match it to the work. A clear subject line and a payment link reduce the effort needed to act.

What does a calm reminder sequence look like?
A useful first reminder says what is due, which invoice it relates to, when it became due and how to pay. Attach or link the invoice again. Ask the customer to reply if anything is wrong. Avoid a long lecture or an accusation.
If there is no response, schedule a second contact and then a human call. Keep the intervals proportionate to the amount, relationship and stated terms. Stop the automated sequence as soon as a person raises a real dispute or agrees a payment plan.
How should you separate a dispute from a delay?
A customer who says the work is incomplete needs a different workflow from somebody who says payment will arrive on Friday. Record the specific issue, the owner and the next action. Do not keep sending identical reminders while a complaint is being investigated.
When a promise is made, note the date and amount. Follow up after that date rather than restarting the entire sequence. This protects the relationship and gives the office a useful history if the debt later needs formal action.
When do legal late-payment rules apply?
For business-to-business work, GOV.UK says a payment is generally late 30 days after the customer receives the invoice or the goods or service when no payment date was agreed. Agreed periods are usually limited to 60 days for business transactions unless a longer period is fair to both businesses.
The same guidance explains when statutory interest and fixed recovery charges may be available on late commercial debts. Consumer jobs, disputed work and contractual terms can change the position. Do not present an automated charge as legal advice. Check the contract and get professional help before formal recovery.

What should a payment-chasing control list include?
- Correct customer and billing contact.
- Invoice and job reference.
- Issue date, agreed terms and due date.
- Delivery evidence and current balance.
- Reminder dates, responses and promises.
- Dispute owner and next action.
- Final escalation decision made by a person.

Frequently asked questions
When is a business invoice legally late?
If no payment date was agreed, GOV.UK says it is generally late 30 days after the customer receives the invoice or after the goods or service are supplied, if later.
Should reminders stop when a customer disputes the work?
Yes. Pause the routine sequence, record the exact dispute, assign an owner and resolve the issue or document the response before resuming collection.
Can a trade business charge late-payment interest?
Statutory interest can apply to qualifying business-to-business debts. Check the contract and the current GOV.UK rules before adding it.
How many reminders should be automated?
Use a limited, stated sequence. Move unanswered cases, broken promises and disputes to a person rather than sending reminders indefinitely.
