AI automation for accountants: how UK practices are spending less time chasing clients and more time on billable work

The average UK accounting practice spends 3 to 5 hours per week chasing clients for bank statements, receipts, and signed documents. That is entirely non-billable time. There are tens of thousands of accounting practices in the UK, mostly small with 1 to 10 staff, and document chasing is consistently the most complained-about admin task. AI automation replaces manual chasing with automated reminder sequences triggered by deadline, not by a staff member remembering to send a follow-up.

How to automate client document chasing for tax returns and year-end

The most effective document request sequences run backwards from the filing deadline: an initial request 8 weeks out, a first reminder at 4 weeks, a second at 2 weeks, and a final prompt 1 week before. Each message stops automatically when the client confirms documents have been sent. Make.com connects to Gmail and Google Drive so the trigger fires when a filing deadline is entered in a spreadsheet or your practice management system.

If you use Practice Ignition or Karbon, both integrate with Make.com. The sequence is built once and runs for every client on the list without manual intervention. The practice manager reviews exceptions, not the entire list.

How to automate VAT return reminders and HMRC deadline alerts

VAT returns recur quarterly for every VAT-registered client on your books. The deadline is fixed; the reminder should be automatic. An automated sequence per client, triggered from a calendar or spreadsheet with their quarter-end dates, removes the manual chase list entirely.

For practices moving clients to Making Tax Digital (MTD), the same automation logic applies to quarterly reporting obligations. The trigger changes; the sequence structure remains the same.

How to onboard new accounting clients automatically

A new client onboarding sequence sends the engagement letter automatically on sign-up, followed by a document checklist, a reminder if the letter has not been signed within 5 days, and a welcome message once everything is received. DocuSign or Adobe Sign connect to Make.com so the signature status triggers the next step without any manual checking.

The time saving on onboarding alone is typically 45 to 60 minutes per new client. For a practice taking on 30 new clients a year, that is 22 to 30 hours recovered per year from one automation.

What does automation cost a UK accounting practice?

Make.com starts at £9 per month. Google Drive is typically already in use. DocuSign costs from £10 per month per user. A three-workflow package built by a specialist takes roughly 30 days to go live and costs from £395 setup plus a monthly management fee. The ROI is straightforward: if 3 hours of non-billable document chasing per week are recovered and billed at £75 per hour, the monthly value recovered is around £975.

Frequently asked questions

Will it work with Practice Ignition or Karbon?

Both integrate with Make.com. Practice Ignition has a native API. Karbon connects via webhook or email triggers. A specialist can map the integration during setup.

Is client data GDPR compliant?

Make.com offers EU data hosting and provides a Data Processing Agreement. Client data passing through an automation is typically transient: a name, email, and deadline date. Your data processing agreement with Make.com covers this. Review it alongside your existing client data handling obligations.

Can it send reminders via WhatsApp as well as email?

Yes, via Make.com connected to WhatsApp Business. Some clients respond faster to WhatsApp than email, which can improve document receipt times further.

What about MTD compliance?

Automation does not file anything on a client's behalf. It sends reminders and collects documents. All filing remains with the accountant. MTD compliance is not affected by automating the chasing workflow.
