A business should consider instructing a commercial debt collection agency when an invoice or account is overdue, internal reminders are no longer changing the debtor’s behaviour, and the debt has been checked and supported by the relevant documents. Referral may be appropriate sooner where payment promises have been broken, contact is being avoided, cash flow is being affected or there are signs that the debtor’s financial position is deteriorating.
There is no single number of overdue days that fits every account
The right time to refer an overdue business debt is rarely determined by a fixed 30, 60 or 90-day rule. The contract, trading history, value of the account, debtor behaviour and commercial relationship all matter.
A customer who is seven days late but communicating clearly may be lower risk than a customer who is 45 days late, has ignored every reminder and has broken two promises to pay. Good credit control looks at behaviour as well as age.
Internal chasing has stopped working
- Several reminders have been ignored.
- A promised payment date has passed.
- The debtor avoids calls or will not give a clear position.
- There is no genuine dispute, but payment is still withheld.
- New invoices are becoming overdue while older ones remain unpaid.
- The balance is affecting cash flow or taking disproportionate staff time.
A clear internal route still exists
- The payment is only slightly late and communication remains constructive.
- An invoice error, missing purchase order or delivery query needs correcting.
- A genuine dispute needs evidence or operational input.
- An agreed payment plan is being honoured.
- The customer has provided a credible payment date that fits your risk tolerance.
Six signs that internal credit control has run its course
1. Your reminders are being ignored
Repeated emails with no meaningful response usually indicate that another reminder written in the same way is unlikely to change the outcome. A professional third party can reset the conversation and make clear that the matter has moved beyond routine credit control.
2. A payment promise has been broken
A promise to pay is useful only if it is kept. One missed date may have an explanation, but repeated broken promises are a strong signal that the account needs closer control and a firmer next step.
3. The debtor gives excuses but no workable proposal
There is a difference between a genuine short-term problem supported by a realistic payment proposal and a sequence of changing explanations with no commitment. The latter increases the risk of delay without resolution.
4. The account is getting older or larger
Allowing new invoices to become overdue while an older balance remains unpaid can turn a manageable account into a material exposure. Referral can help contain the position and establish whether continued trading is commercially sensible.
5. The relationship would benefit from a neutral third party
Involving a professional agency does not have to mean aggressive contact. A relationship-led collector can separate the payment conversation from day-to-day trading and give both sides a clearer route to resolve the account.
6. The time spent chasing outweighs the value of keeping it internal
Senior staff, finance teams and account managers can lose substantial time repeating the same activity. When internal effort is no longer producing movement, specialist recovery can be a more proportionate use of resources.
Checks to complete before referring a business debt
A well-prepared instruction gives the recovery agency the best opportunity to understand the account quickly and contact the correct party. Before placement, gather:
- The debtor’s correct legal name, trading name and contact details.
- The relevant invoices and a current statement of account.
- The contract, order, purchase order or agreed terms where available.
- Evidence of delivery, completion or acceptance.
- The due date and the payment terms that applied.
- A record of reminders, calls, promises and responses.
- Details of any dispute, credit note, part payment or counterclaim.
If the debtor has raised a genuine dispute, identify exactly what is disputed and what evidence answers it. A collection agency can help create engagement, but it cannot replace the commercial or legal evidence needed to support the debt.

What should a professional debt collection agency do?
A professional commercial debt collection agency should do more than send increasingly forceful letters. It should understand the trading relationship, check the account information, create meaningful contact and work towards payment or a credible proposal.
The approach should normally include:
- Account review. Understanding the balance, documents, history and commercial objective.
- Professional debtor contact. Explaining the claim clearly, listening for genuine issues and establishing the debtor’s position.
- Resolution activity. Seeking payment in full or, where appropriate and authorised, a satisfactory payment proposal.
- Clear reporting. Keeping the client informed about contact, commitments, disputes and risk.
- Proportionate escalation. Recommending legal action only where the evidence, value, debtor position and likely return support it.
Debt collection agency or solicitor?
Commercial debt collection and legal recovery are connected, but they are not the same process. A collection agency is usually the appropriate next step where the primary need is engagement and amicable recovery. A solicitor may be needed where there is a substantive legal dispute, limitation concern, urgent protective action or a decision to issue proceedings.
For court claims, the Civil Procedure Rules expect parties to exchange enough information to understand each other’s position, consider settlement and take reasonable, proportionate steps before proceedings. Litigation should generally be treated as a last resort rather than the automatic first response to a late invoice.
The specific Pre-Action Protocol for Debt Claims generally applies where a business is seeking payment from an individual, including a sole trader. Claims against limited companies are normally governed by the wider pre-action conduct rules. The correct route depends on the debtor type and circumstances, so obtain legal advice where needed.
Can interest and collection costs be added?
For some qualifying UK business-to-business debts, statutory interest and certain recovery costs may be available under the Late Payment of Commercial Debts (Interest) Act 1998 and the Late Payment of Commercial Debts Regulations 2013. Entitlement can be affected by the contract, the nature of the transaction and the legal basis used for the case.
Rezolva Connect reviews the placement information and applies relevant amounts on the basis recorded for the account. Recovery of interest or added collection costs cannot be guaranteed. Use qualified wording in final reminders and do not state that an amount is legally due unless the basis has been checked.

A practical referral checklist
Consider referral when you can answer yes to most of the following:
- The account is overdue under the agreed terms.
- The invoices and debtor details have been checked.
- Normal reminders have not produced payment or a satisfactory proposal.
- Any genuine dispute has been identified and addressed as far as possible.
- The debtor’s behaviour or financial position makes further delay a concern.
- You are ready for a professional third party to take over the payment conversation.
Frequently asked questions
How overdue should an invoice be before it goes to collections?
There is no universal waiting period. Use the agreed payment terms, customer history, value, debtor behaviour and risk. Referral may be sensible after internal reminders stop producing progress, even if the account has not reached a particular age.
Will using a debt collection agency damage the customer relationship?
It depends on the agency and approach. Professional, respectful contact can protect the relationship by separating the payment issue from ordinary trading and giving the customer a clear opportunity to explain a genuine problem or make a satisfactory proposal.
Can a disputed invoice be referred?
Yes, but the dispute should be documented and assessed. The creditor must still be able to explain the basis of the balance and supply supporting evidence. A substantive legal dispute may require legal advice rather than routine collection activity.
What documents will a collection agency need?
Usually the invoices, statement of account, debtor details, due date, relevant terms and a summary of previous contact. Contracts, purchase orders, delivery evidence and correspondence should also be supplied where they support the debt or answer a dispute.
Is instructing a collection agency the same as taking legal action?
No. Commercial collection normally focuses on pre-legal engagement and amicable recovery. Legal action is a separate escalation that should be considered on its merits if collection does not resolve the matter.
