What to include in this invoice format

  • Retainer period and service scope
  • Campaign/project-specific line items
  • Tax, discount, and reimbursement sections
  • PO/reference number where required
  • Payment instruction and reminder terms

How to prepare this invoice

  1. 1Get the client PO number before invoicing. An agency invoice without one is the single most common reason payment stalls in procurement.
  2. 2Split the retainer and any overage onto separate lines. A client who sees one lump sum disputes the whole invoice; one who sees the overage line disputes only that.
  3. 3Use SAC per service — 998365 for advertising, 998311 for consulting, 998391 for design. An invoice mixing them needs a line each, not one code for the whole.
  4. 4Show reimbursed costs at cost on their own line. Media spend passed through at cost is not your revenue and should not inflate your turnover.
  5. 5Send it to the finance contact and copy the account contact. Chasing the person who briefed you is chasing someone with no authority to pay.
