  • Show expenses as separate lines with "receipts attached" notes.
  • For retainers, show the retainer credit and the remaining balance.
  • Reference the statement of work or engagement letter.

Frequently asked questions

How do consultants invoice retainers?

Show the retainer amount paid, deduct the work performed against it, and carry the remaining balance forward. Itemize any overage separately.

Should consultants bill expenses separately?

Yes — list reimbursable expenses as their own line items marked at cost, so the client sees exactly what they are paying for.
