Reference the engagement letter / SOW
Always include the engagement reference (e.g. "EL-2026-0034") in the Notes section. Large clients reconcile invoices by EL number — without it, payment can sit unprocessed for weeks.

Frequently asked questions
- Should I send a separate invoice for expenses?
- For larger engagements, yes — it makes the audit trail cleaner and many clients pay expenses faster than fees. For small projects, a single invoice with separate lines is fine.
- How do I bill a day rate?
- Set Quantity to the number of days and Rate to your day rate (e.g. Quantity: 5, Rate: 1,500). The tool will calculate $7,500 automatically.
