Why is a annual fee increase letter important?
Using a formal annual fee increase letter ensures that both you and your client have a shared understanding of the work to be performed, the fees involved, and the legal responsibilities of each party. This reduces the risk of disputes and scope creep.
How to customise this template?
Open the template and replace the bracketed placeholders like [Client Name] and [Firm Name] with the relevant details. Ensure you review the legal clauses to match your firm's specific terms and conditions.

Frequently asked questions
Is this template legally binding?
While this template covers standard professional requirements, it should be reviewed by your legal counsel to ensure it meets your specific firm needs and current legislation.
Can I use this for all clients?
Yes, but you should tailor the specific service schedules and fee structures to each individual engagement.
How often should I update it?
We recommend a full review of your engagement documents at least annually or when professional body guidance changes.
Is a digital signature sufficient?
Yes, digital signatures are widely accepted in the UK for these types of professional agreements, provided there is a clear audit trail.
What if the client wants to change terms?
Any changes to these terms should be mutually agreed and documented in writing as an addendum or a revised letter.
Does this cover AML requirements?
Yes, specific clauses regarding Anti-Money Laundering (AML) compliance and the client's duty to provide ID are included.

Why organised billing matters for accounting firms
Late or missed invoices quietly damage cash flow. Linking billing to the services you have agreed with each client makes it easier to charge for all the work you deliver.
Healthier cash flow
Invoices raised on time, with a clear record of what is outstanding, reduce the time spent chasing payment.
Fewer missed charges
When fees are tied to agreed services, one-off extras and recurring work are less likely to be forgotten.
Fewer fee disputes
Clients who signed a proposal or engagement letter setting out the fee are less likely to challenge an invoice.
Better pricing decisions
Seeing what each client pays alongside the work involved shows where fees need reviewing.
Practical tips from UK practice
- Agree fees in a signed proposal or engagement letter before work starts.
- Keep your services catalogue up to date, so prices on new proposals are consistent.
- Review unpaid invoices every week, not only at month end.
- Review fees annually, and be ready to explain changes in scope.
