Why agencies are exposed to late payment

Three structural features create the agency cashflow problem. First, payment terms in agency contracts are usually 30 days, but agency clients (especially larger corporate clients) routinely pay on 60, 75, or 90 days regardless of the agreed terms. Second, agencies are vendor consolidations: the client procurement team treats the agency as a category and applies whatever payment terms the procurement framework dictates. Third, creative work is subjectively assessed. A client who wishes to delay payment can always find something to "tweak" in the deliverable.

The result is that agencies absorb a disproportionate share of the UK economy's late‑payment problem. Industry surveys from the IPA, IAB, and major sector trade press consistently show agencies running 15 to 30 percent of accounts receivable past 60 days overdue at any given time.

The Late Payment Act applies in full

The Late Payment of Commercial Debts (Interest) Act 1998 applies to every B2B agency engagement. Statutory compensation (£40 to £100 per invoice depending on amount), statutory interest at 8 percent above the Bank of England base rate, and reasonable recovery costs are all recoverable from the client in addition to the principal.

Most agencies under‑use the Act because invoking it feels confrontational with a client they hope to retain. The recovery firm sits between the agency and the client, applying the Act with formality, while the agency‑client relationship is preserved at the principal‑to‑principal level. The client pays; the agency keeps the relationship; the recovery firm absorbs the difficult conversation.

Retainer arrears

Retainer arrears are the most common pattern we see in agency recovery. The client signs a 12‑month retainer at a monthly fee. The agency invoices monthly. The client pays the first three or four invoices on time, then begins paying late. By month nine the client is two months in arrears. The agency is reluctant to escalate because the retainer represents a meaningful percentage of revenue and termination would be expensive.

Our approach to retainer arrears: a single demand for the cumulative sum (not invoice by invoice) with statutory compensation calculated per invoice and statutory interest accruing daily on each. The arithmetic is unambiguous. The client receives one letter quantifying the full position. Most settle within Letter II.

Where the retainer is still active, we coordinate the demand with the agency's account team so the relationship management continues separately from the recovery action.

Project disputes

Project work creates a different recovery profile. The agency completes the project, the client signs off (or fails to formally sign off but accepts the deliverable into their marketing programme), and the final invoice issues. The client then raises objections to the deliverable as grounds for delaying or reducing payment.

The recovery practitioner's first reading: was there a contractual acceptance process? Most agency contracts include either an explicit acceptance clause (the client must sign off within X days) or an implicit one (use of the deliverable in the client's marketing programme constitutes acceptance). Where the client has used the work, the matter is not a quality dispute; it is a debt.

Where there is a genuine dispute about the work itself, the agency's contract typically defines a revisions process or a warranty period. Disputes raised outside that process and after the invoice falls due are usually procedurally weak.

Specific agency contract clauses we look for

  • Acceptance provisions (express, implicit, or absent).
  • Revision rounds and the cap on revisions included in the fee.
  • Late payment charges (most agency contracts include these but rarely enforce them).
  • Termination rights and notice periods on retainers.
  • The kill fee (a percentage of the project fee payable if the client cancels mid‑project).
  • The IP transfer clause (most contracts hold IP rights pending payment; this is leverage).

The IP‑rights lever

Most well‑drafted agency contracts include a clause that intellectual property rights in deliverables transfer to the client only on payment in full. Where the contract has this clause and payment is overdue, the agency retains the IP. The client cannot lawfully continue to use the work in their marketing programme.

This is a powerful commercial lever. A client running a campaign built on agency‑produced creative cannot afford the IP risk of continuing to use unpaid work. We reference the IP clause expressly in Letter I where it is in force. Most clients pay rather than face the IP exposure.

Our approach to agency debt recovery

Our intake form for agency matters asks for the contract or master services agreement, the unpaid invoices, any acceptance or sign‑off documentation, and any objections raised by the client to date. We assess within twenty‑four working hours.

If we accept the matter, Letter I issues the same day. It cites the Late Payment Act, the contractual payment terms, the contractual acceptance process where engaged, and the IP clause where it provides leverage. Recovery costs are payable by the client; the agency is not out of pocket for our fee.

Most agency clients settle within Letter II. The procedural escalation costs them more than the invoice; the reputational risk of a CCJ is unacceptable to most marketing directors. Where settlement is not reached, the matter proceeds to county court claim.


Common questions on agency debt

The client says they are not happy with the work. Do I have to refund?

Almost never, if the client signed off or used the work in their marketing programme. Subjective dissatisfaction raised after acceptance is not a defence to payment. The contract's revisions and warranty processes govern any genuine quality concerns.

The client says they will pay when their next campaign budget is approved. Is this acceptable?

This is the most common stalling tactic. It is not a contractual basis for delaying payment. The Late Payment Act applies regardless of the debtor's internal budgeting. Statutory interest accrues daily.

Can I retain the IP if they have not paid?

If your contract says so, yes. Most agency contracts make IP transfer conditional on payment in full. We reference the clause in our demand letter where it is in force.

What about a kill fee for a project the client has cancelled?

If the contract includes a kill fee clause, the kill fee is a contractual entitlement and recoverable as a debt. Statutory compensation, interest, and recovery costs apply on top.
