What Is a Change Order?
A change order is a written amendment that prices new work added after a contract is signed, typically billed at the freelancer's standard rate plus a 10–25% integration premium.
How change order works
A change order prices new work at the freelancer's standard rate plus a 10–25% integration premium, formalized as a signed written amendment before the added work begins. It applies whenever a client requests anything outside the original scope of work: extra pages, a new feature, an additional revision round beyond the agreed limit, or a reversed earlier decision. The freelancer documents the new task, attaches a price, and requires the client's signature, which converts informal "quick favors" into billable, enforceable line items. The integration premium exists because added work mid-project costs more than the same work quoted upfront; it forces context-switching, re-testing against existing deliverables, and rework of already-completed pieces. A developer charging $100 per hour bills change-order work at $110–$125 per hour. The practical implication for pricing is that change orders convert scope creep from an unpaid liability into a revenue stream. A freelancer who silently absorbs three "small" requests donates 6–10 unbilled hours; a freelancer who issues a change order for each captures that time at a premium and trains the client to batch requests instead of drip-feeding them. Change orders also protect the timeline: each signed amendment can extend the deadline, so the freelancer is not held to the original delivery date while doing 30% more work. Write the change-order process directly into the contract, specifying that any work beyond the documented scope requires a signed amendment at standard rate plus the stated premium. This single clause is the difference between a profitable project and one that quietly erodes the effective hourly rate to below the floor.
Example
Adding a payment integration to a flat-fee website build
Maya quotes a $6,000 flat fee for a 5-page small-business website, with a scope of work covering design, build, and one revision round. Her standard rate is $100/hour. Three weeks in, the client asks her to add Stripe checkout and a products page, which were never in the original scope. Maya estimates the work at 12 hours. Instead of absorbing it, she issues a change order: 12 hours x $100 = $1,200, plus a 20% integration premium ($240) to account for re-testing the new checkout against the existing site, for a total of $1,440. The change order also extends the deadline by one week. The client signs, and the project total rises from $6,000 to $7,440. Had Maya done the work as a 'quick favor,' she would have donated $1,440 of labor and effectively dropped her rate on the project from $100/hour to roughly $79/hour.
