Agencies are often owed for retainers, completed projects and media spend they fronted for a client. We collect using statements of work, approvals and delivery records, in a tone that does not damage your reputation.
Why marketing & creative agencies invoices go unpaid
- Clients going silent after delivery
- Disputes about scope or results
- Media spend advanced on the client's behalf
Scope disputes
Approval emails and delivery records usually settle "we never agreed to that." We assemble them before the first contact.
Agency work is approved in many small steps: a creative brief, round-one concepts, revisions, a final sign-off in Slack or a project tool. We export those approvals into a simple timeline so the client sees, in its own people's words, that the work was requested and accepted.
How agency billing breaks down
Agencies usually bill a monthly retainer, project milestones, or hours against an estimate, plus pass-through costs such as paid media, printing, stock licenses or influencer fees. Pass-through costs are where the most money is at risk. An agency that places a media buy in its own name may owe the publisher or ad platform whether or not the client pays, so a client that stops paying turns a margin problem into a cash emergency.
Retainer clients fall behind quietly. The marketing lead who hired you leaves, the new CMO pauses all vendors for review, and invoices sit unapproved. Project clients tend to dispute at the end: the website launched, the campaign ran, and the final milestone payment is suddenly in question.
What clients say, and how we respond
- "The campaign didn't perform." Unless your contract ties fees to results, the client paid for the work, not a guaranteed outcome. We point to the scope of work and the deliverables.
- "This was out of scope." We match each disputed item to a change request, estimate approval or email asking for the extra work.
- "We never approved that media spend." We produce the signed insertion order, media plan approval or the budget email.
- "The new team doesn't know about this contract." The agreement binds the company. We send it with the invoices to the current decision-maker.
- "We're unhappy, so we'll pay half." We separate any specific complaint from the undisputed balance and push for payment of what is not in question.
Ownership of the work as leverage
Many agency agreements say that ownership of creative work, code or brand assets passes to the client only on payment in full, and that the client gets a license in the meantime. If your contract says this, a client using your unpaid logo, website or campaign assets may be using them without the rights it thinks it has. We raise this carefully and only where the contract supports it, because it is a serious point and should be stated accurately.
Agencies also often hold practical access: ad accounts, domains, hosting or analytics set up under the agency's login. Before you change access, check your agreement and get advice. Locking a client out of its own accounts can create a counterclaim that is worse than the unpaid invoice.
Contract terms that prevent the next unpaid retainer
- Bill retainers in advance, not in arrears
- Require the client to pay media and pass-through costs before you place the buy, or to contract directly with the platform
- State that ownership of deliverables transfers on payment in full
- Define a revision limit and a written change request process
- Allow work to pause after a set number of days past due
- Name a billing contact as well as the marketing contact
A typical agency collection timeline
On day one we review the contract, statements of work and approvals, and identify who controls payment at the client, which is often the CFO or controller rather than the marketing lead. The first demand goes to both the same day. Most agency clients respond within two to three weeks, often with a request to pay over a few months. If the client disputes everything or goes silent, we send you a written recommendation with the evidence, the cost of suit and a realistic view of the client's ability to pay. Nothing is filed without your approval.
Documents that make your claim collectible
- Contract and statements of work
- Approval emails and deliverables
- Invoices
- Media receipts
Frequently asked questions
The client says the results were poor. Do they still owe us?
Most service agreements pay for work performed, not for outcomes. If the work was delivered as agreed, the invoice is usually collectible.
Can you recover media spend we fronted for a client?
Yes, if the client approved the buy and agreed to reimburse it, which most agency agreements and insertion orders provide. We collect it with the media receipts and approvals, and it often carries more urgency than the fee portion.
We only had an email agreement. Is that enough?
Often it is. A clear email exchange about scope and price, followed by delivery and approval of the work, can form a binding agreement. We gather the thread and the delivery record and treat it like any other contract claim.
Will the client know we used a collection agency?
Yes, our notices identify us as acting for you. Our tone is professional, and many agencies find that a third-party demand gets an answer from finance that months of reminders to the marketing team did not.
Can you collect a kill fee when a client cancels a project midway?
Yes, if your agreement provides a cancellation or kill fee, or if work was completed before cancellation. We bill for the work delivered and the agreed fee, supported by the files and approvals from before the cancellation.
