A marketing agency invoice bills a client for a monthly retainer, a project, or both, itemized by channel or deliverable so the client can see what each part of the fee covers. It differs from a generic invoice mainly in how it's itemized — bundling everything into one line invites the question "what exactly did I pay for."
Channel-by-channel line items
Break the retainer into its component services (paid social, SEO, content, email) rather than one total, so the client can map the invoice to the reporting conversation.
Billing period
Which month this invoice covers, especially for a recurring retainer.
Ad spend, if applicable
Kept as its own line, separate from the management fee, whether passed through at cost or marked up.
Retainer reference
A reference to the signed retainer agreement, so the scope backing the invoice is traceable.
Copy this into your own document, or open it directly as a branded starting point in Hanko. Bracketed text like [Client Name] is a placeholder to fill in.

It can be, but keep it as a separate line item — bundling it in makes both the management fee and the media cost harder for the client to evaluate.
As a separate invoice or a clearly separated section, since project work and the retainer usually have different payment terms and shouldn't be confused for scope creep on the retainer itself.
