Campaigns end with evidence,
not invoices.
On Admarket the buyer's money is held by the platform until the campaign is proven to have run. Proof of delivery is that evidence — dated, located, reviewable — and approving it is what releases the payment.
How proof settles a booking
Four moves, and the money only leaves holding on the last one.
- 1
The owner submits evidence
As the campaign runs — and no later than the end of the booked period — the owner uploads the proof the format requires, straight into the order. Dates, locations and files are all recorded on the order itself.
- 2
You have seven days to review
Check the evidence against what you booked: the right site, the right dates, your creative, the agreed condition. Approve it, or reject it with a reason. Do nothing and it approves automatically after seven days — proof cannot sit unanswered forever.

Approval releases the payment
The moment proof is approved — by you or by the seven-day clock — the held payment releases to the owner, less the platform's seller-side commission. The order completes and both sides review each other.
- 4
Rejection opens a dispute
Reject the proof and the order goes to dispute: both sides put their evidence in the thread and the platform decides — release, refund, or something in between. The money stays held until it is settled, which is exactly why it was held at all.
What proof looks like, format by format
Each medium has its own natural evidence. The listing states exactly what the owner will submit — this is the standard.
| Format | What the owner submits | What you check |
|---|---|---|
| Billboards | Dated, GPS-tagged photographs — a long shot placing the site and a close-up of the posted creative. | Right location, your artwork, posting date within the booked period, sheet in good condition. |
| Digital screens | Play-out report from the screen's player — loop position, plays per day — plus an on-screen photograph. | Play counts match the booked share of the loop, across the booked dates and hours. |
| Transit | Depot photographs of the wrapped or carded vehicles, with fleet numbers visible and dates recorded. | Number of vehicles agreed, correct routes or depot, fitted for the full period. |
| Radio | Transmission log from the station's play-out system — every spot with its air date and time. | Spot count, dayparts and dates match the booked schedule. |
| TV | Transmission certificate from the broadcaster, plus the as-run log for the campaign window. | Spot count, dayparts and the trading demographic match what was booked. |
| Tear sheets — the actual printed page from the issue, with the cover and issue date alongside. | Right title and issue, agreed position and size, print quality readable. | |
| Cinema | Projection play-out report per screen — screenings, dates and the feature each spot ran before. | Screen count and screening numbers match what was booked. |
| Events | Photographs of your branding in place during the event, wide and close, with the event dates. | Agreed positions and sizes, present for the whole event, visible to the audience as sold. |
Owners who can't shoot their own evidence book proof photography as a service — dated, GPS-tagged shots to this standard, taken by local photographers.
Why it works
Buyers stop buying on trust
You never wire money to a stranger and hope. The payment sits with the platform, and it moves only when the evidence says the campaign ran.
Sellers stop chasing invoices
The money is already there, held from day one. Submit clean proof and the payout follows — no 90-day payment terms, no collections calls.
Nothing hangs unresolved
Seven days to review, then automatic approval; rejection goes straight to a decided dispute. Every order ends — with a payout or a refund.
Questions about proof
Why is the payment held at all?
Because in advertising the product is a promise: space in the future. Holding the money until delivery is proven means the buyer never pays for a campaign that didn't run, and the owner knows the money already exists before a single sheet is posted.
What if I miss the seven-day review window?
The proof approves automatically and the payment releases. The window is there to protect sellers from silence, not to catch buyers out — put the campaign end date in your diary and review early.
Who checks that photographs are genuine?
Proof photography carries capture dates and GPS coordinates, and the platform checks them against the listing's location and the booked dates. Anything inconsistent is flagged before it ever reaches you.
The owner can't photograph every poster — what then?
Owners can book proof photography as a service on the same order: local photographers who shoot dated, GPS-tagged evidence to the platform's standard. It is the owner's cost, not yours.
What happens in a dispute?
Both sides present evidence in the order thread — the proof, the booking terms, the creative approvals. The platform reviews it against what was booked and settles the held payment accordingly: full release, full refund, or a partial split where delivery was partial.
Does proof work the same on an AdExchange swap?
Yes — a swap is two orders, each with its own proof. Each side's payout releases when the campaign on its space is proven, independently of the other half of the trade.
Book knowing the money moves last.
Every space on the marketplace settles this way — evidence first, payment second.
