What Should Happen When a Client Leaves Our Bookkeeping Firm, and Why Do We Keep Missing Steps?

Bookkeeping firm offboarding is done from memory, so access, fees and handover steps get missed. We build a leaving checklist that runs across all your systems.

Quick answer — TL;DR

When a client leaves, a dozen small steps across different systems need doing, and without a routine some are always missed: access left open, a direct debit still running, an agent authorisation never removed. We build an offboarding checklist triggered from your practice tool that works through each system, does what can be automated and gives people a list for the rest.

The client left, but not everywhere

A client moves to another firm in the spring. You send a polite email and the new firm takes over. Six months later you notice you are still paying for their ledger subscription on your partner plan. Their direct debit was cancelled but a final invoice was never raised. Two former staff still have access to their file. Your firm is still listed as their agent for VAT.

None of it is dramatic. It is just untidy, and some of it costs money or creates risk.

Why offboarding is so patchy

Clients leave rarely compared with the daily work, so nobody gets practised at it. The steps are spread across many systems: the practice tool, the ledger, subscriptions, billing, HMRC authorisations, the client portal, the document store, the password manager, any add-on apps. Each has its own way of removing a client, and there is no single list.

It also happens at an awkward time. Leaving is often unexpected, sometimes after a disagreement, and the person who looked after the client may be the last one wanting to spend time on it.

What loose ends cost

Subscriptions and add-on apps keep charging the firm. Final work goes unbilled. Access that should have been removed stays open, which is both a data protection concern and a professional one. The new firm asks for handover information and gets it late or incomplete, which reflects on you. And your client list becomes cluttered with half-closed records that distort workload and reporting.

Ledger subscriptionTransferring or cancelling the plan the firm pays for
Add-on appsReceipt, payroll or reporting apps still billed
BillingFinal invoice and stopping recurring fees
HMRC and other agent linksAuthorisations left in place
Staff and portal accessOld users still active on the file
DocumentsHandover pack and retention record

How we build offboarding that finishes the job

  1. Marking a client as leaving in your practice tool starts the offboarding run, with the leaving date and the new firm's details if known.
  2. Automated steps run where systems have APIs: stopping recurring invoices, scheduling the final invoice, listing active subscriptions and add-ons linked to that client, and listing every user with access to the file.
  3. Steps that need a person, such as removing agent authorisations or confirming a subscription transfer with the client, appear as tasks assigned to the right role, with instructions.
  4. A handover pack for the new firm is generated from the ledger and your records, so their professional clearance request can be answered promptly and consistently.
  5. The client's records are marked for your retention policy, so documents are kept or deleted on the right date rather than forgotten.
  6. The run is not closed until every step is ticked, and a manager sees any offboarding still open after a set time.

What you are required to keep and for how long is your policy, set with your advisers. The system follows the dates you give it.

Leaving done properly

Every client who leaves goes through the same steps. Costs stop on time, access is removed, the final invoice goes out, and the new firm gets what it needs. Your client list stays clean. And the whole thing takes less of anyone's time, because the tedious parts are done by the system and the rest arrives as a clear list.

Could loose ends be costing you?

  • You have found subscriptions still running for former clients.
  • Former staff or clients may still have access to files.
  • Final invoices for leaving clients are sometimes missed.
  • Professional clearance requests take a while to answer.
  • There is no written offboarding checklist.

FAQ

Frequently asked questions

The questions readers ask us after this guide.

Still have a question?

Ask us directly — a senior engineer will get back to you.

Ask about your project

Can it remove HMRC agent authorisations automatically?

Not all of these can be done through an API. Where they cannot, the system creates a task with the exact steps and tracks it to completion.

Does it delete client data?

Only on the date your retention policy sets, and only after a person confirms. Until then it marks records as belonging to a former client.

What if a client comes back?

The record is archived, not destroyed, until the retention date, so it can be reopened.

Which practice tools can trigger it?

Any tool with an API or webhook for client status, such as Xero Practice Manager or Karbon. A simple form works otherwise.
