Pricing Mechanics
Change Order
A formal, priced amendment to a project's scope, timeline, or budget that converts out-of-scope work into billed revenue instead of absorbed cost.
Definition
A change order is the single most important contractual tool for preventing margin loss from scope creep. It transforms an informal client request into a documented, priced, and approved amendment to the original agreement. Without a change-order process, every "small additional request" is a direct margin deduction.
Effective change orders include: (1) a clear description of the requested change and its impact on scope; (2) the additional cost (hours or fixed fee); (3) timeline implications; (4) signature or approval field; and (5) a note that work on the change begins only after approval.
Agency research consistently shows that firms with a formal change-order process experience 60-70% less margin erosion from scope creep than those operating informally. The process doesn't need to be bureaucratic — a structured email template with price, scope delta, and approval required is sufficient for projects under €50k.
