Credit control for accountancy practices: the modern playbook

Your clients are bleeding cash to late payment, and your own fees are ageing on the ledger. Both are now an opportunity, not a chore. Here is the modern playbook.

Every accountancy practice runs two credit-control problems at once. Your clients are owed money they cannot get in, and it is quietly wrecking their cash flow and, by extension, their view of you. And your own practice has fees on the ledger that clients have not paid, which nobody enjoys chasing. Both are solvable. Increasingly, both are an opportunity rather than a chore.

The two problems on your desk

Your clients' late payers. Late payment costs UK businesses around £11 billion a year and is a leading reason small firms fail. Clients feel it as stress and overdrafts, and they increasingly expect their accountant to help, not just report the damage after the year end.
Your own aged debtors. Practices are famously bad at chasing their own fees. It feels awkward to send a payment reminder to a client whose accounts you are also preparing, so it slips, WIP ages, and the partners write some of it off.

The old answers to both are creaking.

Why the old model is breaking

For years the choice was: do it by hand (a junior, a spreadsheet, and a stiff upper lip) or outsource to a credit-control agency.

By hand does not scale, is inconsistent, and stops the moment someone is busy or off, which in a practice is always.
An agency is a person you pay to send emails in their name, not yours or your client's, and the good ones are expensive. It also puts a stranger between your client and their customer.

Chasing, meanwhile, stopped being a person-shaped job.

The modern playbook

The practices getting this right treat credit control as a policy that runs itself, with a human in charge:

Set the policy once. Payment terms, when to apply statutory interest, tone, cadence, quiet hours. Written down, applied consistently, to every invoice.
Automate the chasing. The right message to each customer, sent from the business's own name, escalating on a schedule rather than when someone remembers.
Escalate to a real call. The biggest lever most practices are missing. The invoices that ignore three emails get a phone call. Until recently that meant hiring someone. It no longer does.
Keep it in the client's name, and their control. Nothing goes out that they have not set the rules for, and they see every step. You are giving them a credit controller, not handing their relationships to a stranger.
Never touch the money. Payments go straight to the client. The tool chases; it does not become a money transmitter, which keeps everyone clear of the regulatory weeds.

Credit control as a service

Here is the opportunity most practices are sitting on. Cash flow is the number one thing clients worry about, and it is exactly the advisory ground practices are being pushed toward as compliance work commoditises. Offering credit control, run with a tool rather than a team, lets you:

Add a genuinely valued service without building a credit-control department.
Earn advisory revenue on something clients feel every single month.
Make clients stickier. A client whose cash flow you actively protect does not switch over a cheaper quote.

You are not becoming a debt-collection agency. You are giving each client an AI credit controller that works in their name, under rules you help them set.

And yes, your own fees

The same approach fixes the awkward one. Your practice's overdue fees get chased the same calm, consistent, professional way, from your practice's name, without a partner having to make the call. Statutory interest is available to you too. Debtor days come down, WIP stops ageing into write-offs, and no relationship gets bruised, because the chasing was systematic rather than a partner finally losing patience.

What to look for

Xero-native (ideally QuickBooks and FreeAgent too), so it reads the ledger with no data entry.
Sends in your client's name, from their own domain, not a generic third party.
Can actually phone the persistent non-payers, not just email them.
You stay in control, approve-first or fully automated, with a clear audit trail.
Never holds the money. Payment goes straight to the client; the tool is never the merchant of record.

The short version

Credit control stopped being a person-shaped job. For a practice that means two things at once: your clients' late payment becomes a service you can offer rather than a problem you report, and your own aged debtors stop quietly eating your margin. Set the policy, let it run, keep a human in charge.

Frequently asked questions

Will clients mind an AI chasing their customers?

Penny is transparent (she says she is an AI), polite, and works in the client's name under rules they set. Most customers respond better to consistent, professional chasing than to the sporadic, slightly embarrassed kind.

Does this replace our credit-control staff?

It replaces the manual grind, not the judgement. Your people move to oversight and advisory. For smaller practices it means you can offer credit control at all, without hiring for it.

Can we offer it to clients under our practice?

Yes. Through the PennyFlow partner programme each client gets Penny in their own name, with you as the trusted introduction, and you earn on it.

What about our own overdue fees?

Same tool, your practice's name, statutory interest available, and no partner has to pick up the phone.
