Price sprints, feature builds, retainers, change requests, maintenance, and IP terms like a pro. Built for programmers and engineers using the Software Developer Invoice Template, clear answers.
Use time and materials. List hours, rate, and deliverables. Example: “Discovery sprint, 20 hrs @ $150/hr: $3,000; Technical brief PDF: $250.”
Show the starting balance, hours used, and remaining credit. Attach the sprint log. Example: “Retainer deposit: $5,000; Sprint 3 usage, 18 hrs @ $140/hr: $2,520; Retainer balance: $2,480.”
Create a separate change order with its own price and approval. Track hours or a fixed add-on. Example: “Change Order #4: OAuth on mobile: 12 hrs @ $160/hr: $1,920.”
State a short warranty window, then bill fixes after. Separate warranty from maintenance. Example: “Maintenance plan, 10 hrs/month @ $140/hr: $1,400; Post-warranty bug fix: 3 hrs: $420.”
Tie each milestone to an acceptance event. Show percent or amount due. Example: “Milestone 2: API integration complete: 30% of $25,000: $7,500.”
Yes, if your contract allows. Note actual cost, markup, and period; tax rules vary—check local rules. Example: “AWS usage July: $610 + 10% admin: $61: Total $671.”
Use a separate rate and clear time range. Include minimums. Example: “Emergency support, Sat 8–10 pm, 2 hrs @ $210/hr: $420; On-call retainer, August: $300.”
Add a license line with scope, term, and territory. Or a one-time buyout fee. Example: “App source code license, perpetual, worldwide: $4,000” or “IP buyout: $12,500.”
