Principle 01
Keep the debt factual
Use the invoice number, amount, due date and evidence of supply. Correct genuine errors. Avoid accusations about motive that you cannot prove.
Practical guide · Overdue B2B invoices
Chase the invoice.
Keep the relationship.
A good customer relationship is worth protecting. That does not mean the payment conversation should stay vague.
Use a clear four-stage process: check the account, ask for a position, set a final commercial deadline and follow through without turning it into a row.
The principle
Firm does not have to mean hostile.
The relationship is most exposed when the chase becomes emotional, inconsistent or surprising. A professional process keeps the overdue account separate from personalities and makes the next step clear.
Principle 02
Ask for a position
Ask for payment, a dated payment proposal or a specific written dispute. "It is with finance" is contact. It is not a payment position.
Principle 03
Make the next step predictable
Give one clear date and say what happens if it passes. Do not make threats you will not carry out, and do not quietly restart the same chase.
A four-stage escalation framework
Four stages. No theatre.
The exact timing depends on the contract, the size of the invoice and what the customer says. The sequence matters more than sending reminders on a fixed number of days.
Stage 01 · First miss
Check before you press
Confirm the contracting entity, due date, amount, credits, payment history and whether delivery or completion can be evidenced. Fix anything genuinely wrong before escalating.
Example wording
"Invoice [number] for £[amount] fell due on [date]. Please confirm the payment date, or tell me today if there is a specific issue with the invoice."
Stage 02 · Reminder failed
Require a position
Move away from "just checking in". Give the customer three useful ways to respond: payment, a dated payment proposal or a specific written dispute.
Example wording
"Please confirm by [date] whether the invoice will be paid in full, whether you propose a specific payment date, or whether any amount is disputed and why."
Stage 03 · Position still vague
Set the final commercial deadline
State the date, the acceptable responses and the next operational step. Keep the wording proportionate and confined to the overdue invoice.
Example wording
"We want to resolve this without affecting the wider relationship. Unless we receive payment or a specific written position by [date], we will move this invoice out of routine credit control for external recovery review."
Stage 04 · Deadline passed
Follow through calmly
Do not send another version of the same reminder. Take the step you named, record the missed deadline and keep future trading decisions separate.
Example wording
"We did not receive payment or a specific position by the deadline. The invoice will now be referred for external commercial recovery. Any decision about future work will be dealt with separately."
These are operational templates, not legal notices. Check every fact, adapt the wording to the contract and do not name a step you are not prepared to take.
The decision point
Know when ordinary chasing has run its course.
Protecting a relationship does not mean every late invoice must leave credit control. It means making a conscious decision based on the customer's position and the risk you are carrying.
Keep it in credit control
The account is still moving.
- This is a recent, one-off delay and the customer is engaging usefully.
- A credible payment date has been given and has not yet passed.
- A specific administrative problem has an owner and a dated route to correction.
- A narrow, evidenced dispute is being assessed rather than used as a general stall.
Move it to recovery
The account is only resetting.
- One or more dated payment promises have been missed.
- "Finance", "approval" or "next payment run" is repeated without a firm date.
- No specific dispute is stated, despite a clear request for one.
- A final commercial deadline has passed and the evidenced invoice is still not moving.
Skip the routine route when needed.
Where litigation or formal insolvency is already under way, a substantial dispute exists, a legal time limit may be approaching or urgent protection may be needed, speak to a solicitor promptly. Pre-legal recovery is not a substitute for urgent legal advice.
Commercial and legal boundaries
Protect the relationship without surrendering the position.
The safest communication is accurate, proportionate and tied to a step you can actually take.
Keep personalities out
Write about the account, the evidence and the deadline. Do not accuse the customer of dishonesty, insolvency or deliberate avoidance unless you have a proper basis for saying so.
Separate future work
Credit limits, new supply and suspension of work are separate commercial and contractual decisions. Check the agreement and take advice before changing performance where the consequences are material or unclear.
Use statutory rights carefully
Statutory interest and fixed compensation may be available on qualifying late commercial payments. Check the contract and the current GOV.UK guidance before adding them. The Vindox calculator provides an estimate, not legal advice.
Use public support where eligible
The Office of the Small Business Commissioner may be able to help an eligible small business with an unresolved payment problem involving a larger customer.
This page provides general operational information for business-to-business invoices in England and Wales. It is not legal advice. The contract, the parties and the facts of the matter determine the available options.
When in-house credit control has stopped moving it
A new voice, using the same facts.
Vindox handles serious overdue B2B invoices through a defined 21-day pre-legal cycle. The communication is firm, documented and confined to the account. It does not rely on embarrassment, public pressure or invented legal threats.
No process can promise that a trading relationship will survive unchanged. The aim is to end the drift and establish one of four usable positions.
Outcome 01
Payment
The debtor pays you directly. Vindox does not hold client money.
Outcome 02
Dated payment proposal
A specific amount and payment date that can be accepted, rejected or monitored.
Outcome 03
Written dispute
A specific position identifying what is disputed and why, so it can be assessed on its facts.
Outcome 04
File for review
If unresolved, you receive an organised chronology and evidence file for solicitor review.
Defined 21-day cycle
Debtor pays you directly
No recovery, no fee
Common questions
The relationship question, answered plainly.
How do you chase an overdue invoice without damaging the customer relationship?
Keep the communication factual, consistent and predictable. Confirm the invoice and due date, ask for payment or a specific written position by a dated deadline, explain the next step and follow through. No process can guarantee that the commercial relationship will be unaffected.
How many payment reminders should I send before escalating?
There is no fixed number. A recent one-off delay with useful engagement can stay in credit control. Escalation becomes reasonable when routine reminders or promised dates have failed and a clear final deadline produces no payment, dated proposal or specific dispute.
Should I stop work for a customer who has not paid?
That is a commercial and contractual decision. Check the contract and your continuing obligations before suspending supply or work, and take legal advice where the consequences are material or unclear.
Will using commercial debt recovery end the customer relationship?
Not necessarily, but nobody can promise the relationship will survive unchanged. A professional external process can keep the overdue account separate from day-to-day contacts, while the debtor's response remains outside the creditor's control.
Can I charge interest without damaging the relationship?
Statutory interest and fixed compensation may be available on qualifying late commercial payments. Check the contract, the facts and current GOV.UK guidance before adding them. The Vindox calculator gives an estimate, not legal advice.
When should I skip recovery and speak to a solicitor?
Seek legal advice promptly where there is a substantial dispute, litigation or formal insolvency is already under way, a time limit may be approaching, or urgent legal protection may be needed. Vindox provides pre-legal commercial recovery and does not litigate or give legal advice.
