Prompt of the Week 🧠

Scope Creep Shield → Turn “quick favor” requests into paid work without losing the client.

Every service business bleeds margin through small “can you just…” asks that never hit an invoice. This prompt turns your project scope into a decision system: it classifies each request, prices the real cost of a free yes, and writes the exact reply for either path.

Prompt:

You are my scope management assistant. I run a service business and I want to handle out-of-scope client requests professionally, without doing free work or damaging the relationship.

Here is the agreed scope for this client (proposal, contract, or SOW):
[PASTE YOUR SCOPE]

Here is the client's new request:
[PASTE THE REQUEST: email, Slack message, or call notes]

Do the following:

1. CLASSIFY THE REQUEST
Compare the request against the agreed scope and label it:
- IN SCOPE (covered, just do it)
- GRAY ZONE (arguably covered, explain both readings)
- OUT OF SCOPE (clearly new work)
Quote the exact scope language that supports your call.

2. ESTIMATE THE TRUE COST
Estimate the hours involved plus the hidden costs of saying yes for free: context switching, delayed milestones, and the precedent it sets.

3. DRAFT 3 RESPONSE OPTIONS
- The Free Yes: for when absorbing it is worth the goodwill. Include one line that frames it as a one-time courtesy so it does not become the default.
- The Paid Yes: a short, friendly reply that welcomes the request and attaches a price and timeline. Draft the actual change-order wording.
- The Redirect: a reply that offers an in-scope alternative or parks the request for a future phase.
Each option should be 3-5 sentences, warm and confident, with zero apologizing.

4. UPDATE MY GUARDRAILS
Suggest one sentence to add to my future proposals that would prevent this exact type of creep.

Tone: collaborative, not defensive. The client should feel taken care of, never nickel-and-dimed.

Where to use it: Perfect for agencies, consultants, freelancers, and fractional operators, or anyone who bills for scoped work. Run it in ChatGPT or Claude the moment a “tiny ask” lands in your inbox, before you reply.
