What to include

A strong consultant invoice should make the work, date, amount, and payment terms obvious. Include your business name, client name, invoice number, invoice date, due date, line items, tax if applicable, total due, and payment instructions.

Example line items

  • Strategy workshop
  • Research and analysis
  • Implementation support
  • Monthly advisory retainer

Template note

Separate advisory time from deliverables so the invoice matches the engagement letter.

Suggested payment wording

Net 15 or Net 30 depending on client size. Retainers are best billed in advance.
