Scope creep

What it is#

Scope creep is the slow, mostly unannounced expansion of what an agency actually does for a client beyond what the engagement was sold to cover. It rarely arrives as one big request. It arrives as a series of small ones — "can you also look at…", "while you're in there…", "quick favor…" — each individually reasonable, collectively a second unbilled retainer.

It is distinct from a deliberate scope expansion, which is negotiated and repriced. Scope creep is the version nobody decided on.

Why it matters for agencies#

Scope creep is one of the primary ways a profitable retainer quietly becomes an unprofitable one. Because the extra work is unbilled and untracked, it doesn't show up in any report — it shows up as a team that's always busy, margins that drift down, and a client who now considers the expanded scope to be the normal baseline.

The defenses are all about visibility:

• A specific statement of work that says what is and isn't included, in writing.
• A regular status cadence that surfaces requests as they arrive, while they're still small enough to flag.
• A reporting habit that makes delivered work visible, so "everything we did this period" is on the record and out-of-scope work can be named as such.

In SendBriefs specifically#

A recurring status brief makes the delivered-work record explicit every cycle. When out-of-scope requests are visible in the brief next to the contracted work, the scope conversation can happen early and calmly — not at renewal, as a grievance.
