Accounts Receivable for Marketing and Creative Agencies

Marketing, media and creative agencies get paid late mostly because client approval chains are long and agency invoices mix several kinds of charges. A retainer, a project fee, out of scope work and pass through media spend can all land on one bill, and one questioned line holds the rest. The fix is agreeing scope and billing rules before work starts, separating charges so each can be approved on its own, and following up on a fixed schedule so the account team never has to chase a client they also need to keep happy.

Professional services firms, a group that includes agencies, average about 43 days of DSO, with a typical range of 30 to 58 days, and the firms sitting at 55 days or more are usually the ones without automated follow-up after the invoice goes out (Credit Pulse DSO benchmarks). Across US B2B credit sales, 43% of invoice value was overdue in 2025 (Atradius, 2025). For an agency that pays freelancers, production vendors and media owners before the client pays, those days add up quickly.

This page covers how advertising and digital marketing agencies, media buying firms, public relations and content studios, design and branding shops, and video and production companies bill, why their receivables stall, and how follow-up should work for their clients.

Most agencies bill several ways at once, often to the same client in the same month.

Monthly retainers

Retainers cover an agreed scope of ongoing work, billed monthly in advance or in arrears. They are the most predictable invoices an agency sends, until the client starts asking what the retainer covered that month.

Project and campaign fees

Campaigns, rebrands, websites and content series bill by milestone or as a fixed fee split into stages, such as a deposit at kickoff and the balance on delivery. The milestone has to be accepted before the invoice is approved, and acceptance often depends on a creative sign off.

Media spend and production costs

Agencies that buy media or manage production often pay media owners, printers, studios and talent on the client’s behalf, then bill those costs through with a fee or markup. These are often the largest invoices an agency sends, and the agency carries the cost until the client pays.

Hourly and out of scope work

Extra rounds of revisions, rush requests and work beyond the agreed scope are billed hourly or as additional fees. Like change order billing in construction, they are the charges most likely to be questioned when nobody approved them in writing first.

Most late payments in agency work come from approval gaps and billing surprises, not clients refusing to pay. Five causes account for most of the delay.

Creative approval is not invoice approval

The marketing manager who loved the campaign is rarely the person who releases payment. If the invoice does not reach accounts payable with the right PO and an internal approver named, it waits in an inbox.

Out of scope charges nobody agreed to

An invoice that adds revision rounds or rush fees the client did not expect invites a question. The whole invoice can sit while one line is discussed.

Large clients and procurement rules

Brands and enterprise clients often pay on long terms through procurement systems that reject invoices without a matching PO or a completed supplier setup. Our guide to selling to large companies with slow payment systems covers how to work inside those approval chains.

The agency fronts the money

When media or production costs are billed through, the agency has often already paid the vendor. A slow client then becomes the agency’s cash problem, and if a few large clients carry most of the balance, that concentration risk can affect the whole business.

Nobody wants to make the call

Account managers own the relationship and are reluctant to chase payment from the client they also have to pitch next quarter. Follow-up waits, and the invoice ages.
