Use a brief before issuing an invoice.
A change brief describes proposed work and its commercial terms. An invoice requests payment for an agreed charge; it should not be the first place a client discovers that the scope or fee changed.
“Change order,” “scope addendum” and “change brief” can mean different things in different agreements. Use the name that fits your process. The content and approval record matter more than the label.
This is a practical drafting template, not a legal contract or a guarantee of enforceability. Adapt it to the original agreement, the project and the requirements that apply to your business.
Copy the template and add the actual details.
CHANGE BRIEF · [reference] · [revision] Prepared on: [date] Project: [name] Prepared by: [agency and contact] Prepared for: [client and contact] Original agreement: [reference / date / relevant scope] REQUEST [What changes and why.] DELIVERABLES [Specific work you will produce.] EXCLUSIONS [Work not included in this change.] DEPENDENCIES AND ASSUMPTIONS [Inputs, access, decisions or approvals required.] FEE Net additional fee: [currency and amount] Tax: [label, percentage and amount, if applicable] Client total: [currency and amount] Payment terms: [agreed terms] DELIVERY Additional delivery days: [number and day basis] Delivery implications: [effect on dates and dependencies] APPROVAL [Who confirms scope, fee and timing; how and by when.] [Which original terms continue to apply.] SIGN-OFF, IF REQUIRED Prepared by: [name / role / date / signature] Accepted by: [name / role / date / signature]
Remove fields that are irrelevant, but do not remove a real dependency or approval requirement just to fit the document onto one page.
A worked website change.
Aster Studio is preparing a journal collection for Harbor’s website. This is an illustrative scenario, not a real customer case study.
Harbor / Website — journal collection
Scope: Add a journal section using the existing visual design and content system.
Deliverables: One collection, one reusable article template and one listing page. One review round covers the templates.
Exclusions: Copywriting, bulk content entry and additional integrations.
Dependency: Harbor supplies approved copy and images before the build begins.
Fee: USD 800.00 excluding tax. At an illustrative 5% rate, tax is USD 40.00 and the client total is USD 840.00.
Delivery: Two additional business days; confirm the revised date after the required content is received.
Approval: Confirm scope, fee and dependencies in writing before additional work begins. Remaining original terms continue to apply.
Use the actual applicable tax treatment and agreed payment terms. Do not copy the example’s tax rate without checking it.
Review the terms before sharing.
- Client, project, reference and revision match the proposed change.
- Deliverables are specific enough to establish what “done” means.
- The fee says whether tax is included or added, and totals agree.
- Additional days say whether they are business or calendar days.
- Dependencies explain what can affect the revised date.
- The authorized approver and approval method are identified.
- Signature images have not been mistaken for recorded approval.
- Internal cost or margin notes are absent from client-facing text.
For a scope exchange, list removed work and replacement work. For a deferred request, avoid wording that accidentally commits a price or delivery date.
Inspect the public demonstration PDFs.
The samples show how a brief and an invoice present scope and fees at different points in the workflow. They do not show approval by a real customer.
The free workspace includes document previews. Protected customer PDF exports require activated export services, which are not yet enabled on the public deployment.
Try the workflow with the sample project.
Compare an agreed baseline with a new request, review the costs, choose a response and inspect the client document preview.
The public release currently offers a free demo. Checkout, license activation and protected customer PDF exports are not yet enabled. Planned lifetime prices are USD 49 for one activated browser/device and USD 99 for five independent browsers/devices. Team data does not synchronize.
