Before the Administrator Calls: A Credit-Control Playbook for UK Professional Firms

Most professional firms treat credit risk as a collections problem. It is not. By the time an invoice is overdue by ninety days, the decision that mattered was taken months earlier — at onboarding, in the wording of the engagement letter, in the decision to keep billing a client whose accounts were already late.

The distinction matters because insolvency is not a single event. It is a slope, and the public record usually shows the gradient long before the administrator is appointed. Firms that build a light credit discipline into their routine recover most of what they are owed. Firms that do not tend to learn the news from Companies House, alongside everyone else.

The signals are public, and mostly free

A UK company in distress leaves a trail. Late filed accounts, a change of registered office to an accountant's address, a director resigning in numbers, a mortgage charge registered against the assets, a winding-up petition advertised in The Gazette — none of these is conclusive on its own, but together they describe a business under strain.

Two filings deserve particular attention. The first is a notice of intention to appoint administrators, which buys the company a short moratorium while it negotiates. The second is a resolution to wind up voluntarily, filed alongside the appointment of a liquidator. Both appear quickly on the public register. A firm with a monitoring routine will see them within days; a firm relying on its debtor ledger will see them when the cheque does not arrive.

County court judgments are the other useful, and often overlooked, indicator. A single unsatisfied judgment is not fatal. A pattern of them, particularly from suppliers in the same trade, is a serious warning.

Contracts that give you options

Credit control is easier when the engagement letter was written with it in mind. Four provisions are worth the negotiation.

Billing in advance. A monthly retainer billed on the first working day of the month is, in substance, a rolling deposit. It shifts the firm from financing the client to being financed by it. Where the client resists, a smaller upfront deposit plus a shorter billing cycle achieves much of the same effect.

A suspension right. The engagement letter should allow the firm to pause work if an invoice remains unpaid beyond an agreed period, or if the client enters a formal insolvency process. Without that clause, a firm that stops work may find itself accused of repudiatory breach.

Milestone billing. For project work, tying invoices to deliverables rather than calendar months limits the value at risk at any point. It also makes the conversation about payment easier, because there is something tangible to point to.

A lien over papers and files. For solicitors and some other regulated professions, a lien is a well-established right. For others, an express contractual right over work product until payment is received is a sensible substitute.

Personal guarantees are worth considering for smaller, owner-managed clients, but they should be taken deliberately and documented properly. A guarantee extracted at the point of distress is unlikely to be enforceable and may be challenged by a liquidator.

The first seventy-two hours

When a client enters administration or liquidation, speed matters more than eloquence. The firm's objectives are narrow: establish the exposure, register as a creditor, and protect whatever leverage remains.

Start with a written statement of account, addressed to the insolvency practitioner and copied to the client. It should show the full balance, the invoices that make it up, and any retention or deposit already applied. Practitioners work from claims, not from recollections.

Next, review what the firm still holds. Completed work product, original documents and any client money should be identified and, where the contract permits, held pending payment. This is not aggression; it is the orderly application of terms the client agreed to.

Finally, decide whether to continue supplying. Administrators often need professional advisers to keep trading, and there is legitimate work available. But credit terms extended after the firm knows, or ought to know, that the company is insolvent carry real risk. Any continued engagement should be on cash-upfront terms, agreed in writing with the practitioner.

Two firms, one client

Consider a fictional illustration. Kestrel Retail Ltd, a regional homeware retailer, engaged two professional firms in the same quarter.

Marchmont Creative, a design studio, billed a £9,000 project in three stages, with the first invoice payable before work began. When a county court judgment appeared against Kestrel in the autumn, the studio's monthly credit review flagged it. Marchmont paused the final stage under its suspension clause and wrote to the client. When Kestrel entered administration six weeks later, the outstanding balance was £4,800, of which £2,900 was covered by a deposit already held. The studio ultimately recovered £3,900 — roughly 81 per cent.

Pell & Rowe, a marketing consultancy, worked on a rolling monthly basis with sixty-day payment terms and no deposit. By the time the administrator was appointed, the outstanding balance stood at £34,000 across seven invoices. Pell & Rowe learned of the appointment from Companies House, three days after the event, and submitted its claim in the ordinary way. As an unsecured creditor it received a distribution of approximately four pence in the pound: £1,360.

The difference between the two outcomes was not luck. It was the engagement terms and a monthly habit of looking.

Making the discipline routine

None of this requires a credit department. It requires a named owner, a short checklist, and a recurring slot in the calendar.

At onboarding, run a Companies House search and a credit reference check, and record the result. Set an internal credit limit — many firms use 10 per cent of monthly revenue per client as a working ceiling. Review the aged debtor list monthly, not quarterly, with an explicit watch list for clients showing two or more warning signals. Review terms annually, particularly for clients on legacy arrangements that predate the current management.

The aim is not to avoid risk. Every firm that extends credit to a growing client is taking a calculated position. The aim is to take it knowingly, with the contractual tools to limit the damage and the routine to see the trouble coming. In 2026, with insolvency levels in parts of the UK economy still elevated, that discipline is less a precaution than a basic operating requirement.
