Definition
A Change Order (or Change Request) is a formal, written amendment to an existing [Statement of Work (SOW)](/glossary/sow) that alters the project's scope, timeline, or budget. Once signed by both parties, it becomes legally binding.
Explanation
If the SOW is the shield, the Change Order is the sword.
In [Fixed Price Contracts](/glossary/fixed-price-contract), clients frequently ask for "small favors"—an extra revision, an additional report, a slightly different feature. If the delivery team agrees to these without a Change Order, they are engaging in [Scope Creep](/glossary/scope-creep) and causing immediate [Margin Leakage](/glossary/margin-leakage).
A Change Order process forces the client to acknowledge that their request has a commercial impact. Often, when a client is told that their "small tweak" will cost $5,000 and delay the project by two weeks via a Change Order, they decide the tweak isn't that important after all.
The Zero-Dollar Change Order
Not all Change Orders increase the budget. A "Zero-Dollar Change Order" is used to formally document a change in scope that offsets itself (e.g., "We will build Feature A instead of Feature B, for the same price") or a change in timeline caused by the client (e.g., "The client was two weeks late providing API access, so the final delivery date is pushed back two weeks at no extra cost").
Commercial Checklist for Change Orders
- SOW Foundation: Does your original SOW explicitly define the Change Order process? If it doesn't, you have no contractual mechanism to enforce one.
- Stop Work Clause: Does the contract state that work on the new scope will not begin until the Change Order is signed?
- Margin Protection: Are Change Orders priced using the standard [Rate Card](/glossary/rate-card), or is there a premium attached for disrupting the delivery schedule?

When should you issue a Change Order?+
Immediately when a client requests work that is outside the bounds of the original SOW. Do not do the work first and ask for a Change Order later.
Why do Project Managers avoid Change Orders?+
Because they are socially uncomfortable. It requires telling a client 'No, that will cost extra.' Strong commercial organizations train their PMs to view Change Orders as revenue opportunities, not conflicts.
