Ten per cent, and here is everywhere else the money goes.
The platform fee is 10% of media spend, disclosed on every line, with no spread and no undisclosed margin anywhere in the path. Above £25,000 of trailing 30-day spend it drops to 5% plus a £749 monthly platform fee.
AI asset production is charged separately at a published rate and is never blended into the media fee. Those are all the fees there are, and the rest of this page is about the ones that are not ours: channel floors, data CPM uplifts, and the budget below which none of this is worth doing.
One rate on media, and a second that switches on when your spend does. Both are charged against a ledger entry per delivery row rather than summarised at the foot of a statement.

Up to and including £25,000 of trailing 30-day media spend
One fee ledger entry accrues per delivery row, carrying the date, the campaign, the channel, the spend and the fee. The fee is visible against the media it was charged on rather than summarised at the bottom of a statement.
Scale

When it applies
Strictly above £25,000 of trailing 30-day media spend
The tier is evaluated on trailing 30-day spend, so it switches on when your spend does rather than at a contract renewal. The monthly fee is charged for any month in which the scale tier was active on any day, and it appears as its own statement line.
// the tier is evaluated on trailing 30-day media spend, and the comparison is strictly greater than £25,000. At exactly £25,000 the standard rate still applies.
If the tier boundary lands awkwardly against how you actually phase spend, bring the shape of it to the 45-minute working session and we will work it through.
Four monthly budgets, the tier each falls in, and the arithmetic that produces the figure. The second row is the boundary condition, and it is on this page rather than on your first invoice.

None of these figures include media. The spend column is what the sellers receive; the fee column is what we receive on top of it, and it is the only thing on the statement that is ours. What the sellers charge, and the floors they enforce before a plan will build at all, are set out further down.
assets
AI asset production, charged separately on purpose
Finished assets are a distinct hard charge, priced at an 80% margin on raw provider cost — retail is cost divided by one minus the margin, so 5× cost, floored at 50p — debited from the wallet at submit and automatically refunded if the provider fails. It never touches the media fee.

Blending asset costs into a media percentage is how an ad-tech margin becomes invisible. Keeping them apart costs a simpler headline and buys a statement where every line can be checked against something.
two caveats on the numbers to the left
Two caveats, both from us. The cost bases these prices derive from are unverified — the configuration template says in capitals that they have not been reconciled against a live provider invoice and must be before real customers are charged. And the 80% is a pricing rule computed against raw provider cost, excluding storage, compute, egress, support and overhead, so it is not an achieved gross margin. The ladder reprices from configuration at run time, so treat these as a current default rather than a committed price list.
and one number that is not here
There is deliberately no "versus traditional production" figure here. We used to carry one, deleted it as unsourced, and added a test that fails if it comes back. Repeating it on a website would be reintroducing a number nobody could stand behind.
how the charge behaves
Debited from the wallet at submit, because a real provider cost is incurred the moment the job goes out, and refunded automatically on a definite provider failure. An ambiguous outcome is treated differently: the charge is retained and retry is disabled, so a duplicate render cannot be produced and billed, and it is cleared by a named human with reconciliation rights rather than on a timer.
Asset production is the one line on this page carrying a margin, so it is the one most worth arguing about. Bring a real creative requirement to the 45-minute session.
Media spend and asset charges both run against a prepaid balance. Seven properties of that balance, each of which is a rule enforced in code rather than a promise in a contract.
01
£100 minimum top-up
The smallest credit the buyer-facing top-up contract accepts. Top-ups, spend, asset charges, asset refunds and the platform fee are five distinct entry kinds in one ledger, so a statement reads as a sequence of events rather than a total.
02
A launch reserves the fee as well as the media
The funding check at launch covers the media and the maximum platform fee on it, not just the media, so a campaign cannot go live with enough money for the buy and not enough for the fee. If the wallet is short, the refusal names the exact amount: "wallet is £X short of the launch commitment", rather than a generic decline you have to work backwards from.
03
Media spend fails closed
A launch that the wallet cannot fund does not launch. The check is enforced by default and callers may only opt into warn-only behaviour for sandbox previews, which is the right way round: a preview that warns is useful, a live buy that warns is a bill.
04
Asset charges are a hard gate with no override
A real provider cost is incurred the moment an asset job is submitted, so there is no warn-only path for assets at all. If the wallet cannot cover it, it does not submit.
05
Funds stay held through the pause boundary
On a live line, a reservation is not released until spend has been reconciled to the provider's own invoice or account export, and the final match is rechecked inside the same transaction as the release. Missing, mismatched or stale evidence keeps the money held.
06
Sandbox credit is not money, and cannot become money
Without a payment key, a sandbox top-up credits the wallet with no payment and no network call at all. Live execution refuses a wallet containing sandbox-minted credit outright, so a sandbox balance can never be spent on real media.
07
GBP only, and VAT is not modelled
The entire money surface is sterling. VAT is not modelled anywhere in the platform and remains an open business decision rather than a configured rate.
// top-ups, media spend, asset charges, asset refunds and the platform fee are five distinct entry kinds in one ledger, so a statement reads as a sequence of events rather than as a total.

Every charge is now on this page. The rest is caveats.

the only comparison on this page
Against a modelled agency fee
The same four budgets, with the fee a typical agency model would produce beside them. The model is ours, which is exactly the problem with it, so the note beside this table is not a footnote and is worth more than the numbers are.
Monthly media spend, the AdBuyMCP fee derived from the published rates, and an illustrative agency fee at 15 per cent of media with a £750 monthly minimum.

the awkward part
Four reasons this might be the wrong purchase
Each of these is drawn from our own go-to-market review, which was written to be read internally and is harder on the product than a marketing page usually is. Three of the four are things you would work out inside the first month, and a supplier who named them in advance is in a different position from one who did not.
01
Below about £10,000 a month, this is the wrong product
The published band starts at £2,000, and at that end the maths does not work for either of us. A 10% fee on £2,000 is £200 a month against a buyer who needs the most support, and a seven-channel plan at that budget is operationally and statistically weak — too thin to pace properly and far too thin to power a lift test. If your total monthly media is under £10,000, buy search and social directly, and come back when you have a second channel worth funding.
02
The fee is not the whole cost of the media
Data segments carry their own CPM uplift — around £2.50 per thousand on Bombora topics and £3.00 on Dun & Bradstreet — and every channel has a plan floor enforced when the plan is built: £100 on search and DOOH, £140 a week on CTV, £250 on audio and social, £500 a week on cinema, £1,000 on addressable TV. Vendor-side minimums are separate and bite later; Sky AdSmart's £3,000 burst is the one most likely to surprise a first plan. Those are the sellers' costs rather than ours, and you see them before you approve rather than in the reconciliation afterwards.
03
You cannot fund a live campaign here today
No buying rail has reached spend-tested or report-verified on our own evidence ledger, so live spend runs inside a design-partner engagement rather than from a self-serve top-up. No fee has ever been charged to a real customer. The sandbox is complete and free, and the supply page grades every rail.
04
There is no published customer outcome yet
No case studies, no reconciled outcome study, no named reference. That is where a product recruiting its first design partners actually is.

The six you ask before you will read anything else on this page.
What does AdBuyMCP cost?
10% of media spend, disclosed per line, with no spread. Above £25,000 of trailing 30-day spend the rate drops to 5% and a £749 monthly platform fee applies. AI asset production is charged separately at a published rate — 50p for an image, £1.25 for a voiceover, £6.00 for ten seconds of standard video — and is never blended into the media fee. There is no subscription and no seat fee at the standard rate. What you do fund up front is the wallet, which is prepaid with a £100 minimum top-up, and above the threshold that monthly fee is a fixed charge rather than a usage one. A per-channel plan floor is enforced when the plan is built.
Is there a hidden margin on the media?
The commitment is that there is none: the fee engine is built with no spread, one ledger entry accrues per delivery row carrying that row's date, campaign, channel, spend and fee, and the terms commit to media passed through at cost with no undisclosed margin, rebate or arbitrage. Being precise about the status of that: it is a contractual commitment and a design property, not yet a demonstrated practice, because no rail has ever spent and therefore no invoice has ever been reconciled against it. The one place a margin does exist is AI asset production, at an 80% margin on raw provider cost — five times cost — published and charged as its own line.
Why is asset production charged separately rather than included?
Because bundling it is how a margin becomes invisible. It is a genuinely harder sell — Universal Ads and Global AdPower both include AI creative — and the honest case is that a separately charged line you can audit is worth more than a free one you cannot. What this page will not do is quote a saving against traditional production to make £15.60 look generous: the platform carried such a figure, deleted it as unsourced, and added a test to stop it returning. There is no sourced production-cost comparison here.
What is the smallest sensible budget?
Around £10,000 a month across everything, and the published floor of £2,000 is lower than that for reasons of packaging rather than sense. At £2,000 the fee is £200, the support requirement is at its highest, and a multi-channel plan cannot carry enough weight on any single line to pace or to prove anything. Two channels funded properly beats a token line on all seven.
Do I pay for the sandbox?
No. The whole loop — brief, persona, seven compiled plans, creative, approval, launch, delivery, measurement, journeys, optimisation — runs with no credentials and no card, and the data it returns is realistic and repeatable rather than a scripted demo. Charges begin at real media and at real asset generation, both of which incur a real cost to somebody.
What happens to my money if a supplier fails?
It stays held. A wallet reservation is only released once spend has been reconciled to the provider's own invoice or account export, and that final match is rechecked in the same transaction as the release. An asset charge is refunded automatically on a definite provider failure — but an ambiguous outcome is different: the charge is retained and retry is disabled, to stop a duplicate render being produced and billed, and it is cleared by a named human with reconciliation rights rather than automatically. An ambiguous supplier outcome is never retried blindly either; it stops the run.
