In-house credit control or a debt collection agency? When to stop chasing and hand it over

Keep credit control in-house while your own reminders, a quantified interest chaser and a letter before action are still doing the work, which for most invoices they do. Hand an account to a debt collection agency at a trigger you set in advance, not at the point you finally lose patience. For most UK businesses the right trigger sits between 60 and 90 days past due, or sooner if the debtor has stopped replying to a named person, broken two promises to pay, or raised a dispute for the first time only after the final reminder. The case for outsourcing is rarely that an agency can do something you cannot; it is that your time has a value, the odds of recovery fall every month, and a third party changes the conversation in a way another email from you does not. An agency is not a replacement for credit control. It is the stage of credit control that most businesses never get round to.

What credit control covers, and where an agency fits

Credit control is everything that stands between issuing an invoice and banking the money: deciding who to give credit to and how much, setting terms, invoicing promptly and correctly, sending statements, reminding on the due date, chasing after it, holding further supply, adding interest, and sending a letter before action when a customer ignores all of that. Done well, it recovers the great majority of invoices without anyone outside the business being involved.

A debt collection agency is what happens when an account resists all of that. It takes over specific overdue debts, writes and calls in its own name, traces debtors who have moved, negotiates and administers payment plans, and reports back. It has no legal powers you do not already have, a point our guide to what actually happens when you instruct one makes early, and it is typically paid a commission on what it recovers. Everything it does, you could in theory do yourself. Almost nobody does, because it is a full-time job with a different temperament from running a business.

The question, then, is not whether to have credit control or an agency. It is where the line between them falls in your business, and whether you cross it on purpose or only when the pain gets bad enough.

The real cost of chasing it yourself

The instinct to keep chasing in-house rests on an accounting error: treating your own time as free.

Take a £5,000 invoice that goes overdue. An owner whose time is worth £75 an hour to the business, a modest figure for many, spends an hour a week on it: checking the ledger, drafting the email, making the call, fielding the excuse, updating the forecast. By day 30 that is £300 of time. By day 90 it is £900, and by then the calls have become the task that gets pushed to Friday afternoon and then to next week. An agency on 10% commission would have charged £500 if it recovered the full amount and nothing if it did not. On the numbers alone, in-house chasing beyond the first month is often the more expensive option, and that is before the cost of what did not get done instead.

The second cost is the recovery odds. Collectability tables are a staple of the collections trade, and the most quoted one, produced by the US Commercial Collection Agency Association, puts the chance of recovering a commercial debt in full at roughly 70% when it is three months old, around 50% at six months and under 25% at a year. UK agencies’ own experience has the same shape, and the reasons are not mysterious: debtors who are struggling pay the creditors who act first, businesses fail, contacts move on, and paperwork goes missing. Every month spent giving a debtor “another few days” is a month in which your place in their queue gets worse. Our guide to why waiting costs more than it seems covers the psychology; the table above covers the arithmetic.

The third cost is the one that shows up in your forecast. An overdue invoice that is being chased inconsistently is not an asset with a plan, it is a hope, and cash flow forecasts built on hopes are how growing businesses run out of money while profitable. An account that has been referred to an agency has a status, a next step and a likely outcome. That alone can be worth the commission.

Seven signals it is time to hand it over

Age is the simplest trigger and it should be in your policy, but behaviour is usually the better guide. Any one of these means the account has outgrown in-house chasing.

1. The debtor has stopped replying to a named person. Late payers reply. Non-payers go quiet. The moment a customer who used to answer your finance contact stops doing so, the in-house channel has closed and a new one is needed. If they have vanished altogether, there is a separate playbook for that.

2. Two promises to pay have been broken. One missed promise is life. Two is a pattern, and the third promise is being made to buy time, not to pay. An agency’s payment plan comes with monitoring and consequences that yours does not.

3. The invoice has passed 60 days without a dispute being raised. An undisputed invoice at 60 days has already survived your reminder, your statement and your interest chaser. What it has not survived is a letter from someone else.

4. A dispute has appeared for the first time after the final reminder. Genuine disputes surface early. A quality complaint that arrives only when the letter before action does is usually a stalling tactic, and an agency deals with those daily. A dispute that turns out to be real needs a solicitor rather than an agency, and a good agency will say so.

5. The account is small in your ledger and large in your head. If one overdue invoice is the thing you think about at 11pm, its cost to you is already out of proportion to its value. Referring it converts a worry into a line item.

6. You are avoiding the call. Most owners are not natural collectors, and there is no shame in that. But an account that is being chased only by email, because the phone call feels confrontational, is being chased with one hand. An agency’s people make that call for a living.

7. The limitation clock is a factor. In England and Wales you generally have six years from the date the debt fell due to issue a claim; in Scotland the period is five and it extinguishes the debt. If an old account has drifted, check how long you have left and refer it while there is still time for the agency’s work and, if needed, a claim.

Four reasons to keep it in-house a little longer

Outsourcing is a decision, not a reflex, and there are accounts that should stay with you.

A genuine dispute you can resolve. If the customer has a real point about quality, quantity or scope, a conversation and a credit note will settle it faster and cheaper than any third party. Resolve the dispute, reissue the invoice, and only then apply the normal timetable to what remains.

A key account where one conversation at the right level will do it. Sometimes an invoice is stuck in a customer’s process rather than refused, and a director-to-director call unblocks it in a day. Make that call once, with a date attached. If the date passes, the account goes.

A debt below the agency minimums. Most agencies set a floor, commonly between £1,000 and £2,500 on our panel, and below it a letter before action followed by a small claim you issue yourself is usually the better route. Our guide to whether an agency is worth it for a small debt works through the sizes, and a ledger of many small balances is a different case, covered below.

A structurally late payer you intend to keep. Some large customers pay everyone at 75 days as a matter of policy. That is not a collection problem, it is a terms problem, and the fix is pricing, deposits, a credit limit or a conversation about the Fair Payment Code, not an agency letter every quarter.

The middle options

The choice is not binary. Between doing it all yourself and instructing an agency sit two other models, and knowing which is which saves money.

Reminder software is worth having whatever else you do, because most in-house failure is forgetting rather than deciding. Outsourced credit control suits a business that invoices a lot and has nobody whose job is the ledger. Neither replaces the agency stage; they make it needed less often and reached more cleanly. If you already have a reliable process to the letter-before-action stage, the agency is the only piece you are missing.

Will an agency damage the customer relationship?

This is the fear that keeps more invoices in-house than any calculation, so it deserves a straight answer.

A customer who values the relationship and has been paying late through disorganisation generally pays when an agency writes, and is often quietly relieved. The matter leaves the personal channel, the awkwardness goes with it, and the next order arrives as usual. A customer who has stopped paying and stopped replying has already left the relationship; the agency’s letter makes that visible rather than causing it. The customers a business actually loses over collections are the ones it chased personally and inconsistently for months, with mounting frustration on both sides, until something was said that could not be unsaid.

You also have more control than you might think. Agencies can be instructed to take a measured, relationship-preserving approach on accounts you want to keep, and firmer handling on those you do not. Say which is which at handover. And put it in your terms of business that overdue accounts are referred after a stated period, so that when it happens it is your policy working, not a personal decision about them.

Write the policy once

The single most effective change most businesses can make is to stop deciding invoice by invoice. Decide the ladder once, while calm, and let it run.

A workable timetable for a business-to-business invoice on 30-day terms looks like this. Day 1 overdue: a short reminder with the invoice attached. Day 7: a statement and a phone call to a named person. Day 14: a formal chaser that adds statutory interest at 8% plus the Bank of England base rate and the fixed compensation due, which the free late-payment calculator works out. Day 30: a letter before action naming the date the account will be referred. Day 45 to 60: referral to an agency, with the file already prepared. Day 90 onwards: with the agency, a decision on a payment plan, litigation or write-off.

The small-business recovery ladder explains each rung in more detail. Adjust the days to your sector and your customers, but write them down, put them in your terms, and give each one a calendar date the moment an invoice goes overdue. A ladder with dates on it runs itself. A ladder without dates is a list of things you meant to do.

Handing over cleanly

The handover is where most of the value is won or lost, and it is short.

Send one final in-house letter with a specific referral date, and keep to it. Prepare a single pack: contract or terms, invoices, statement of account, proof of delivery or completion, every chaser and every reply, and the debtor’s current details. A clean file means the agency spends its first week collecting rather than reconstructing, and what to have ready when you instruct lists the pack in full.

Brief the agency on the relationship, on whether payment plans are acceptable, and on who can answer questions. Get the fee in pounds for this debt, ask what counts as collected, and read the no-win-no-fee small print before you sign. Then stop chasing. Route every contact from the debtor to the agency, tell your team, and if the debtor pays you directly, tell the agency the same day. Two parties chasing the same debt is worse than one.

If you have a ledger rather than a single account, the same logic applies at scale, and it changes which agency you want. Two hundred small balances are one large instruction for a firm built around high-volume, letter-driven recovery, and our guide to choosing by business type covers how process fit and fee model shift when you are handing over batches from an aged-debt report.

Outsource less by fixing the cause

Every account you refer is also a data point about how it got there. Credit-check new customers, and re-check existing ones when order values climb. Get the terms signed before the work starts, and make sure they say what happens when payment is late. Invoice on the day, to the right person, with the purchase order number they asked for. Take deposits or staged payments on anything large. Offer direct debit. Chase on the due date rather than a fortnight after it, because the cost of late payment to UK small businesses is mostly the cost of chasing late.

None of that removes the need for the agency stage. Businesses that do all of it still meet the customer who will not pay. It does mean that when you reach for an agency, it is for the debtor who deserves it, not for the process you never built.

Scotland and Northern Ireland

The logic is the same across the UK and agencies cover all three jurisdictions, but two details change the timetable. In Scotland, prescription generally extinguishes a debt after five years rather than the six in England and Wales, so an old account needs referring sooner, and low-value claims run through Simple Procedure in the sheriff court for sums up to £5,000. In Northern Ireland, the small claims limit is £3,000 and judgments are enforced through the Enforcement of Judgments Office. Set your policy dates with the local limits in mind.

The short version

Chase in-house until your ladder runs out, which for most invoices is the letter before action. Set the referral trigger now, put it in your terms, and apply it without a fresh decision each time: 60 to 90 days, or sooner when the debtor goes quiet, breaks two promises or produces a late dispute. Keep back the genuine disputes, the one-conversation key accounts and the sums below agency minimums. Hand everything else over with a clean pack, a clear brief and a stop date, and then leave it alone. Your time is not free, the odds fall every month, and a letter from someone else is the one thing you cannot send yourself.

When you reach that trigger, comparing costs nothing. On Collect Compare you can compare vetted UK debt recovery agencies blind, on fee model, approach and track record, with names hidden until you choose, or let us match you to the right one for your ledger. It is free for creditors: the agency you choose pays for the introduction, and no agency can pay to rank. If you are not sure what to look for, start with the creditor’s guide to choosing an agency.

This is general information, not legal advice. Fee models and terms vary between agencies, and limitation periods depend on the jurisdiction and the type of debt, so get terms in writing and take advice on any account that is old or disputed.
