Checklist
- Match each line to SOW, PO, or change order reference

Frequently asked questions
- How many line items should a freelance invoice have?
- Use as many as needed for clarity—often three to eight for a milestone bill. One vague line is worse than several specific lines that map to contract sections.
- Should I combine hours and expenses on one line?
- Separate them. AP often routes expenses to different GL codes and may require receipts for reimbursement lines.
- Can I invoice multiple projects on one PDF?
- Only if the client agrees. Otherwise split invoices per project code to avoid rejection.
- What if the client wants SKU or GL codes?
- Ask during onboarding and add a column or prefix to descriptions. Missing codes delay payment more than extra detail.
- Do I show tax per line or on the total?
- Follow your CPA's advice and client state rules. Many service invoices show tax once at the bottom when applicable.
- Should line items match the proposal exactly?
- They should match the signed contract or SOW, which may differ from an early proposal. Always bill against signed documents.
- How do I line-item a rush fee?
- Add a separate line referencing written approval: "Rush delivery fee — approved via email 03/28/2026."
- Is it okay to round hourly totals?
- Round only per your contract (e.g., nearest quarter hour). Show math so the client can reconcile to your timesheet.
- What attachment should I include?
- Include timesheets, milestone sign-off, or delivery proof when the client requires them; otherwise keep the PDF invoice self-explanatory.
