Reducing write offs and scope creep, the invisible cost

Introduction

Every professional firm produces work it does not bill. Hours recorded and then written down, matters that ran twice as long as quoted, questions answered for free because raising a charge felt awkward.

It rarely appears as a line anyone examines. It is simply absorbed into a lower realisation rate, and it is frequently larger than the firm's entire marketing budget.

1. Reducing write offs and scope creep starts with measuring them by matter type

An overall realisation figure tells you there is a problem and nothing about where.

Split write-offs by matter type, by fee earner and by client. The distribution is never even — a small number of categories or clients usually accounts for most of it, and that is where the fix belongs.

2. Separate the four causes, because they need different responses

Under-quoting, where the original estimate was optimistic.

Scope creep, where the work expanded and nobody re-priced it. Inefficiency, where the matter took longer than it should have. And discomfort, where the time was legitimate and somebody chose not to bill it. Each is fixable and only by a different action.

3. Attack scope creep with the engagement letter

The largest single cause in most firms.

Define the included work specifically, name the exclusions, and state that additional work will be quoted and agreed separately. Then actually invoke it. A clause nobody refers to protects nothing.

4. Raise variations at the moment they arise

Scope creep is not a single event. It is thirty small ones nobody mentioned.

The discipline is to say something the first time: this is outside what we agreed, here is what it would cost, shall we proceed. Raised immediately it is routine. Raised at billing it is a dispute.

5. Stop the free advice from becoming the relationship

Short questions answered without charge are good practice. Twenty of them a month for one client is a business model problem.

Either price the client on an arrangement that includes reasonable contact, or be straightforward that a substantial question requires opening a matter. Ambiguity here is what produces the client who consumes hours and generates no revenue.

6. Fix chronic under-quoting with your own data

Estimates in professional firms are frequently optimistic in a consistent direction.

Compare quoted against actual on completed matters by type. If a category consistently runs over, the estimate is wrong rather than the matters being unusual, and adjusting the standard quote is the entire fix.

7. Deal with the client who is genuinely unprofitable

Some clients consume disproportionate time, supply information late, change instructions and query every invoice.

Re-price them, restructure how they are served, or let them go. Firms carry these relationships for years out of loyalty or inertia, while the write-offs they generate subsidise nothing.

8. Give fee earners permission and a route to escalate

Much unbilled work exists because someone junior did not feel able to raise it.

Make it explicit that identifying out-of-scope work is expected rather than awkward, and give them a defined route: flag it to a partner, who has the conversation. Removing the personal discomfort removes most of the leakage.

9. Report write-offs monthly, by matter type

Not as a punishment measure, as information.

Reviewed monthly with the four causes distinguished, it becomes a list of specific process fixes rather than a vague sense that things run over. Firms that do this for a year typically recover more margin than any fee increase would have produced.

Conclusion

Measure write-offs by matter type, fee earner and client, because the overall realisation figure conceals where the loss actually is.

Separate under-quoting from scope creep from inefficiency from reluctance to bill, use the engagement letter against scope creep and actually invoke it, raise variations the first time they arise, define how free advice is handled, correct chronic under-quoting from your own quoted-versus-actual data, address genuinely unprofitable clients directly, give junior staff permission and a route to escalate, and report write-offs monthly by cause.
