What to include
What goes on a Marketing & Advertising invoice?
📈
Services vs. ad spend
Always separate your management fees from ad spend. Ad spend passes through at cost and should never be mixed with your agency fee. Keep them as distinct line items or separate invoices.
📋
Deliverables for the period
List what was delivered - number of campaigns, posts, emails, reports, or ad sets. Clients want to see outputs, not just "monthly marketing services."
📅
Billing period
Include the exact billing period (e.g., Apr 1–30, 2026) so clients can reconcile the invoice against their calendar and there's no ambiguity about what month is covered.
📊
KPIs or performance summary
A brief note on results (e.g., "Campaign delivered 2.4x ROAS") builds trust and reinforces the value of your retainer. Even a one-liner improves client relationships.
Pro tips
Marketing & Advertising invoicing tips that get you paid faster
Invoice retainer clients on the 1st of the month or at the start of the service period, not at the end.
Keep ad spend completely separate from your management fee - co-mingling these is a common billing mistake.
Include a one-sentence performance note on every invoice to reinforce value and reduce cancellation risk.
For project-based campaigns, invoice 50% before campaign launch and 50% on delivery of results.
Auto-reminders are critical for agency invoices - marketing teams are busy and often miss payment due dates.
FAQs
Common questions about marketing & advertising invoices
What should a marketing invoice include?
A marketing invoice should separate your management fees from ad spend, list specific deliverables for the period (campaigns, posts, emails, reports), state the billing period, and include your payment terms.
Should marketing agencies invoice before or after the month?
Most agencies invoice in advance (at the start of the month or project) for retainer work. This ensures cash flow and signals that the work is pre-authorized. Project-based campaigns are usually billed 50% upfront and 50% on delivery.
How do marketing agencies handle ad spend on invoices?
Ad spend should be billed separately from management fees, always passed through at exact cost with no markup (unless your pricing model includes a markup, which should be disclosed). Many agencies issue two separate invoices: one for fees, one for ad spend.
What payment terms work best for marketing agencies?
Net 14 is most common for retainer invoices. Project-based work often uses milestone billing. Net 30 is acceptable for larger clients but can strain cash flow for smaller agencies.
