Short answer: If a customer raises a genuine dispute about quality, quantity, price or a set-off, pause hard chasing and exchange evidence in writing as the Practice Direction expects. Resume collection on any balance that is clearly owed once the facts are settled.
Disputed commercial invoice debt collection needs a different pace from a clean unpaid balance. When a UK B2B buyer raises a genuine dispute — quality, quantity, purchase-order mismatch, or a set-off claim — hard collection, statutory demand pressure, and aggressive chase should pause until the dispute is clarified in writing with evidence. The fee is 15% of what is recovered, payable only when you have been paid. Recovery is not guaranteed.
Debt Collection UK (a trading style of PASECOM GROUP LTD) introduces B2B files to independent partner agencies. We are not solicitors, we are not authorised by the Financial Conduct Authority, and we do not collect consumer credit. PASECOM GROUP LTD was incorporated on 7 April 2026. We introduce commercial claims; we do not issue proceedings. Partners collect. Recovery is not guaranteed.
This article is about when collection should pause on a disputed commercial invoice — not a full repeat of our proof of debt checklist or our chase without damaging the relationship sequence. Money pages: unpaid invoices and debt collection agency.
Is it a genuine dispute or stalling?
A genuine dispute usually points to a specific issue with facts and documents: wrong goods, short delivery, defective work, an unauthorised price change, or a set-off against a counterclaim. Stalling often looks different: vague “we are looking into it” replies, no particulars after a reasonable window, recycled excuses, or silence after you have answered every point in writing.
Treat every dispute as potentially real until you have asked for particulars and compared them to your file. Do not escalate to hard collection while a detailed written dispute is still live and unanswered. Equally, do not leave cash stranded because a buyer said “disputed” once with no evidence. Ask for the grounds, the amount in issue, and the documents that support it — then diary a reply date.
What does the Practice Direction expect you to exchange?
For company-versus-company claims in England and Wales, Practice Direction – Pre-Action Conduct and Protocols expects parties to exchange enough information to understand each other’s position, make efforts to settle without court, and consider ADR where appropriate. That applies when an unpaid invoice becomes a contested commercial claim.
In practice that means:
- 1. Set out your claim clearly (invoice, amount, due date, contract or PO).
- 2. Invite a written response that either pays, proposes a short plan, or disputes with reasons and evidence.
- 3. Reply to a reasoned dispute with your own evidence — do not ignore it and threaten harder.
- 4. Allow a reasonable time to engage — often about 14 days in a straightforward case under the Practice Direction framing.
A letter before action that invites a reasoned reply is usually safer than shouting louder while the file is contested. More detail: letter before action for business debts.
What documents should you gather while collection pauses?
Pause hard chase, but keep working the file. Assemble and update:
- 1. Contract, terms, and purchase order (including any variation).
- 2. Invoice, delivery notes, goods-received notes, timesheets, or completion certificates.
- 3. Emails or meeting notes that show what was agreed and when the dispute was first raised.
- 4. Photos, inspection reports, or third-party quality findings if quality or quantity is in issue.
- 5. A clear schedule of what is admitted, what is disputed, and what remains unpaid.
That pack is the same proof you need before instructing a partner later — see proof of debt documents before debt collection.
When can collection resume?
Collection pressure can resume when:
- 1. The buyer withdraws the dispute in writing and the balance is again undisputed.
- 2. You agree a reduced undisputed sum and the buyer fails to pay that clear balance.
- 3. The buyer never supplies particulars or evidence after a fair written window, and your file shows the dispute is baseless or abandoned.
- 4. Partial payment or a written admission leaves a clear residual balance.
Even then, stay proportionate: soft confirmation of the undisputed figure, then a Practice Direction letter before action if needed, then partner instruction or court advice. GOV.UK explains how to make a court claim for money if you choose that route — we do not issue claims for you.
Do Late Payment rights apply once the debt is clear?
On qualifying commercial debts, statutory interest and fixed compensation under the Late Payment of Commercial Debts (Interest) Act 1998 may still apply once the sum is due and unpaid. A genuine dispute over part of an invoice does not automatically erase rights on any undisputed balance. Those add-ons do not justify aggressive chase while a real dispute is still open.
Why instruct a partner only on a clear balance?
Partners collect best on clear, documented, undisputed commercial balances. Upload an invoice here when the dispute is resolved, narrowed to an admitted sum, or shown to be without substance after you have exchanged evidence. Marketing fee: 15% only when the client is paid; often no-collection, no-fee. Recovery is not guaranteed. Overview: debt collection agency and unpaid invoices.
We introduce B2B files; we are not solicitors; partners collect under their terms. Do not instruct on a live, particularised dispute expecting a partner to “bully through” quality or set-off issues — that wastes time and can damage the file.
Frequently asked questions
Should debt collection pause if a commercial invoice is disputed? Yes when the dispute is genuine and particularised. Pause hard collection and statutory-demand style pressure until you have exchanged evidence and narrowed what is still owed. Soft clarification and a Practice Direction letter that invites a reasoned reply can continue.
What counts as a genuine dispute on a B2B invoice? Specific written grounds tied to quality, quantity, PO or contract terms, pricing, or a set-off claim — with documents or facts that can be checked. Vague delay without particulars after a fair window is closer to stalling.
Does the Practice Direction require me to stop chasing? It requires you to exchange information and try to resolve without court where appropriate. Ignoring a detailed written dispute and escalating aggressively is poor conduct. See the Practice Direction.
Can I still claim Late Payment interest if part of the invoice was disputed? Often yes on any sum that is clearly due and unpaid once the dispute is resolved or narrowed — under the Late Payment Act 1998. Get advice on your facts; we are not solicitors.
Will Debt Collection UK chase a disputed invoice for me? We introduce B2B claims to partners. Partners typically need a clear undisputed balance (or a clear residual after admission). Recovery is not guaranteed. Fee: 15% only when the client is paid.
Does recovery cost nothing if I upload while the dispute is open? No. This guide has no fee. Partner recovery is a fixed percentage of what is recovered (15% only when the client is paid; often no-collection, no-fee). Upload when the balance is clear enough to instruct. Recovery is not guaranteed.
If a commercial invoice is disputed, pause hard collection, exchange evidence under the Practice Direction, and resume only on a clear undisputed balance. The fee is 15% of what is recovered, payable only when you have been paid. Recovery is not guaranteed. Upload the invoice, contract, and dispute trail when you are ready to instruct on a clear B2B balance.
