Hourly, sprint, fixed or retainer
| Model | Line item looks like | Best for |
|---|---|---|
| Hourly | "Backend development, Aug 1–15 — 38.5 hrs × $95" | Open scope; pairs with a time log attached or linked |
| Per sprint | "Sprint 12 (Aug 4–15) — auth & billing epics — $4,200" | Ongoing product work; ticket IDs make it audit-proof |
| Fixed per feature | "Stripe integration per SOW §2 — $3,500" | Well-specified deliverables; changes go on new lines |
| Support retainer | "Maintenance & support — August (up to 10 hrs) — $900" | Keep-the-lights-on work; overage billed hourly |
The sprint line is the developer's superpower: reference the ticket range or epic names and the invoice approves itself — the client's PM already saw the board. Retainer mechanics (including overage wording) are in the retainer guide.

Meetings, reviews and the lines clients question
- Meetings and code review are billable work. Don't hide them in inflated dev hours — name them: "Sprint ceremonies & code review — 4.5 hrs × $95". Named lines get paid; padded ones get audited.
- Urgent fixes carry their own rate. "Production incident, Aug 9 (off-hours, 1.5× rate) — 3 hrs × $142.50" — agreed in the contract, visible on the invoice, never a surprise.
- Scope changes become numbered lines. "CR-3: switch to multi-tenant per Aug 12 call — $1,100". The number points to a written agreement; that habit ends most disputes.
- License and infra pass-throughs at cost. "API credits, August (at cost) — $86.40" — margin on your work, not on someone else's servers.

Ticket ranges, an incident with its agreed multiplier, and the retainer as a flat line — nothing to question. Field basics live in how to create an invoice.
Developer invoicing FAQ
Hourly or fixed price — what should I invoice?
Invoice whatever the contract says, but structure it honestly: hourly needs a period and a rate on the line; fixed needs the deliverable named exactly as scoped. Mixed models work fine as separate lines on one invoice.
Do I bill for standups, planning and code review?
Yes — it's engineering work. Put it on its own line so the client sees the real cost of collaboration instead of suspecting padded dev hours.
Should I take a deposit from a new client?
For fixed-price projects with new clients, 25–50% upfront is standard. For hourly, a shorter first cycle (invoice after week one) does the same job — limits your exposure while trust builds.
My client is overseas — currency and details?
Agree one currency per engagement and keep every invoice in it — the generator supports 159 currencies with correct formatting. Put full transfer details in the notes.
The client wants the invoice to match their PO — how?
Put the PO number next to the invoice number (rename any label on the sheet if needed) and mirror the PO's item wording. Enterprise accounts payable matches documents by reference, not by memory.
