Scope calculator vs. change-order draft: what do you need?

A calculator answers the amount question. A proposed change summary records scope, fee, timing and the request for agreement.

Different outputs solve different problems

A calculator answers “what is this many hours worth at my rate?” A proposed change summary helps communicate “what changes, for what amount, and with what schedule impact?” Neither establishes agreement on its own. If you already have a reliable proposal template, there may be no reason to replace it. Start with the step that actually causes repeated work.

Use a calculator for a rough baseline

For a fictional three-hour request at USD 100 per hour, the baseline is USD 300. That number can help you decide whether to discuss the addition now or keep the original scope. It does not specify the deliverable, the included revision limit, or when the work fits into your calendar. A free calculator is appropriate when you only need the arithmetic.

Use a draft when details keep drifting

Suppose a fee changes during discussion but the old fee remains in an email draft. Bringing scope, amount, and timing into one reviewed workflow can reduce that kind of manual mismatch. AddBriefly uses your estimates and fixed English templates in three tones; it does not interpret the contract, contact the client, or capture a signature. You remain responsible for the proposal and agreement process.

Choose without buying unnecessary software

Stay with the free baseline and your current template for occasional straightforward requests. Consider the paid local tool when preparing these proposals is recurring work and its limitations fit your workflow. If you need team approvals, CRM, invoices, or e-signatures, AddBriefly is not a substitute. Start with the free calculation, then read the product limitations before making a buying decision.
