How Do We Stop Doing Extra Work for Fixed-Fee Clients Without Charging for It?

Fixed-fee accountancy clients get extra work for free because nobody spots it as out of scope. We build scope tracking and extra work requests tied to each job.

Quick answer — TL;DR

Fixed fees work until the client asks for something outside them and it gets done anyway. We record each client's agreed scope from the engagement against their jobs, give staff a simple way to log extra requests as they come in, route those to the manager to price or waive, and show which clients receive the most unbilled extra work.

"Could you just quickly look at this?"

A monthly fixed-fee client emails: could you just look at this mortgage reference letter, and while you are at it, the bank wants a cash flow forecast. The staff member, keen to help, does it. It takes three hours. Nobody records it as extra work, because nobody is sure whether it is included. Next month it happens again.

By the end of the year, the client's fixed fee covers far more work than was agreed, and the practice only finds out when someone compares recorded time with the fee.

Staff cannot see the scope

The engagement letter sets out what the fee covers, but staff rarely read it when a request comes in. It is a PDF in a folder, and working out whether a request is included means opening it and interpreting the wording. So staff default to doing the work, because saying no to a client feels worse than giving time away.

Even when a staff member suspects the work is extra, there is no simple way to flag it. Raising it with the manager means an email and a conversation, and it often feels easier just to do it.

The clients most likely to ask for extras are often the ones the practice likes most: responsive, friendly, growing. That makes staff even less keen to raise the question of cost.

What scope creep costs

IssueEffect
Scope not visible to staffExtra work done without question
No way to flag requestsExtra work never priced
Fixed fees erodedSome clients cost more than they pay
Found at year endToo late to raise it naturally with the client
Uneven treatmentSome staff charge, others do not

It also creates unfairness between clients. Those who ask for little subsidise those who ask for a lot, and the practice's pricing stops reflecting the work actually being done.

How we make scope visible and extra work visible too

  1. Each client's agreed services and any limits, such as number of payroll runs or included meetings, are recorded as structured data from the engagement, rather than living only in the PDF.
  2. The scope is shown on the client record and next to each job, in plain language staff can check in seconds.
  3. When a request comes in, staff log it with one click from the client record or by forwarding the email. The system marks it as in scope, out of scope or unclear, based on the recorded services.
  4. Out-of-scope and unclear requests go to the client manager to price, include or waive, and the decision is recorded.
  5. If priced, a short quote or additional fee note goes to the client for approval before the work starts, using wording your practice approves.
  6. A report shows each client's extra requests, what was charged and what was waived, which informs the next fee review.

Your practice decides what is in scope and what to charge. The system makes those decisions visible at the point where the work is requested.

Extra work gets noticed

Staff know what a client's fee covers without opening a PDF. Extra requests are logged instead of quietly absorbed. Managers decide consciously whether to charge. Clients get used to being told when something is extra, which usually goes better than a surprise at the fee review. And the practice can see which fixed fees are no longer working.

Is this happening at your practice?

  • Fixed-fee clients regularly ask for extra help
  • Staff rarely check the engagement letter
  • Extra work is not logged anywhere
  • Recorded time on some clients far exceeds the fee
  • Some staff charge for extras and others do not

Ask about your project

Do we need to redo our engagement letters?

Not necessarily. We record the agreed services from your existing letters. Some practices use the exercise to tighten wording, but that is your choice.

Will staff find logging requests a burden?

Logging is one click or a forward, which is quicker than an email to a manager. That is the point.

Does it connect to our practice software?

Where the system has an API for clients and jobs, scope and requests sit alongside the existing record.

What drives the cost?

The number of service types and limits, how engagements are stored today and the systems it links to.
