What Are Change Orders?
A change order is a formal document that modifies the scope, timeline, or cost of a service engagement after the original agreement has been signed. Change orders are the professional mechanism for adapting to evolving requirements without undermining the original agreement or creating disputes.
In the world of service agreements, change is inevitable. Clients discover new requirements, market conditions shift, technical complexities emerge, and priorities evolve. Without a formal change order process, these modifications happen informally — through emails, phone calls, or casual conversations — leading to confusion about what was agreed to, how much it costs, and when it will be delivered.
Why a Change Order Process Matters
Prevents Scope Creep
Scope creep is the gradual expansion of a project beyond its original boundaries. It happens one "small" request at a time, and before long, the provider is delivering significantly more than the agreed scope without additional compensation.
A change order process makes scope changes intentional. Every modification must be documented, evaluated, and approved before work begins. This does not mean saying "no" to changes — it means saying "yes, and here is what it will cost."
Protects Revenue
Without change orders, the provider absorbs the cost of scope changes. This erodes margins, extends timelines, and creates resentment. A formal process ensures that additional work is priced appropriately and approved before it is performed.
Maintains the Paper Trail
Change orders create a documented history of how the project evolved from its original scope. This paper trail is invaluable if a dispute arises about what was agreed to, how much was spent, or why the project took longer than expected.
Keeps Projects on Track
Change orders force both parties to evaluate the impact of each modification on the overall project timeline, budget, and resources. This prevents the accumulation of small changes that individually seem manageable but collectively derail the project.
Change orders are not a barrier to flexibility. They are a framework for managing flexibility. The best client relationships embrace change orders as a collaborative tool rather than viewing them as adversarial.
How to Structure a Change Order Process
Step 1: Request
Either party identifies a desired change and submits a written change request. The request should include:
- Description of the proposed change
- Reason for the change
- Desired timeline for implementation
- Reference to the original scope item being modified (if applicable)
Step 2: Assessment
The provider evaluates the change request and determines its impact on:
- Scope — What additional work is required
- Timeline — How the change affects the project schedule
- Cost — The additional fees for the change
- Resources — Whether additional personnel or tools are needed
- Dependencies — How the change affects other deliverables or project phases
Step 3: Proposal
The provider prepares a change order document that includes:
- Change order number (for tracking)
- Reference to the original agreement
- Detailed description of the change
- Impact on timeline (revised milestones or delivery date)
- Impact on cost (additional fees, revised total)
- Any changes to other terms (resources, assumptions, dependencies)
- Signature lines for both parties
Step 4: Approval
Both parties review and sign the change order before any work begins. The signed change order becomes an amendment to the original agreement.
If the client rejects the change order, the project continues under the original scope. If the client wants to negotiate the terms, the provider revises the change order and resubmits.
Step 5: Execution
Once approved, the provider incorporates the change into the project plan and begins the additional work. The change order fees are added to the project invoicing schedule.
Never begin work on a change order before it is signed. The moment you start work without approval, you lose the leverage to ensure payment for that work.
Change Order Clause Language
Your service agreement should include a change order provision that addresses:
Authority
Designate who has the authority to request and approve change orders on behalf of each party. This prevents situations where a junior team member requests additional work, the provider delivers it, and the client's decision-maker refuses to pay because they never authorized the change.
Minimum Documentation
Specify what a valid change order must contain at minimum (description, cost impact, timeline impact, signatures from authorized representatives).
Pricing Methodology
Define how change order work is priced:
- Hourly rates — At the rates specified in the original agreement, or at a premium rate for rush requests
- Fixed quotes — The provider quotes a fixed price for each change order based on the scope of the modification
- Time and materials with a cap — The provider bills actual time spent up to a maximum amount
Timeline Impact
State that approved change orders may extend the project timeline. The extension should be proportional to the additional work required and documented in the change order.
Cumulative Threshold
Some agreements include a provision that triggers a comprehensive project review if cumulative change orders exceed a certain percentage of the original project value (e.g., 25% or more). This ensures that a project that has fundamentally changed scope is re-evaluated holistically rather than managed through incremental modifications.
Emergency Changes
Address how urgent changes are handled when the standard process is too slow. You might allow verbal authorization for emergency changes, followed by a written change order within a specified period (e.g., 48 hours). Emergency changes might carry a premium rate.
Common Change Order Mistakes
- Making the process too cumbersome — If a change order requires a 5-page document and two weeks of review, both parties will avoid using it and revert to informal changes
- Not pricing change orders appropriately — Change orders should reflect the true cost of the additional work, including the disruption to the existing project plan
- Failing to track cumulative impact — Each change order might seem small, but their cumulative effect on timeline and budget can be significant
- Approving changes verbally — Verbal approvals are hard to enforce. Always get it in writing.
