How do we prove scope creep on a design contract?

Scope creep is slow. Small requests add up, and no single one feels worth a fee. The proof comes from the total, so a running list matters.

Start with the fee proposal, the brief and the deliverables list. Then add the later emails, meeting notes and file versions. Mark each item as inside scope, outside scope or unclear.

Be fair about the unclear items. A claim that admits what is arguable is more believable than one that treats everything as extra.

Present the result as a table with item, date, requester, hours and fee. Use it in the next client talk or in a formal claim.
