How to invoice as a marketing agency

Agency invoices mix a monthly retainer, project or campaign fees, and pass-through ad spend that should never look like agency revenue. Separating managed spend from your fee is essential — finance teams reject invoices that blur the two.

This template opens with retainer, campaign and ad-spend lines. Add a PO number, apply tax, and produce a PDF that an accounts-payable team can approve without questions.

What to include

Client name and PO number
Monthly retainer / management fee
Project or campaign work
Ad spend, passed through at cost
Billing period and tax details

Typical terms: Net 30 · ad spend billed at cost

Frequently asked questions

How do I separate ad spend from agency fees?

List managed ad spend as its own pass-through line at cost, clearly labelled, and keep your retainer and project fees on separate lines. Finance teams need that split to process the invoice and to treat the spend correctly.

Does the template support a PO number?

Yes — there is a field for a purchase-order number, which most agency clients require before accounts payable will release payment.

Is the marketing agency invoice template free?

Yes — create and download it with no account. A free account adds saved clients, reusable invoices and payment tracking across retainers.

Is this invoice generator free?

Yes — CalculatorAI's invoice generator is completely free. You can build, customise and download as many professional PDF invoices as you want, with no signup, no watermark and no trial limit. A free account simply adds extras like saved clients, invoice history and the Invoices Tracker.

Do I need an account or a credit card to make an invoice?

No. You can generate and download an invoice without an account and without entering any payment details. Signing up is free and unlocks saved client details, reusable invoices and payment tracking — but it is never required to create an invoice.

Track every invoice you send

Turn this template into a system. The Invoices Tracker keeps your clients, payment status and totals in one place — so you always know who has paid and what is overdue.
