Profit ROAS · Acquisition
The ROAS that counts
the costs behind the order.
Every channel measured against the return it needs to break even after VAT, goods, shipping, packaging and fees — so a busy ad account and a profitable one stop being the same thing.

VAT, goods and feesThe ad spendWhat stays
Each platform claims revenue. Take out the VAT inside it, the goods and the fees, then the ad spend, and what is left is what the channel made. Break-even here is 1.93× — the return a channel must show before it makes anything — and all three clear it.
01 / The case for it
Revenue ROAS counts money that was never yours.
Without it
An ad platform divides attributed revenue by spend and reports a number. That revenue still owes the tax inside it and the cost of the goods it sold — so a campaign can clear 3× on the dashboard and lose money in the accounts.
What Profflow does
Measured against what the advertising has to come out of.
Advertising is paid for out of contribution — what is left after tax and the cost of goods — not out of the headline. That is the figure Profflow divides by, which is why it and the ad platform disagree.
02 / Worth understanding
The number an ad platform will never show you
ROAS is measured against revenue, and revenue is not yours
A 4× return sounds decisive until you take out the VAT inside the price, the goods, the shipping and the payment fee. What is left decides whether the campaign made money, and the ad platform has never seen any of those numbers.
Break-even is per channel, not per account
Channels sell different products at different margins. One break-even figure for the whole account hides the campaign that sells your thinnest-margin product and looks fine on a blended chart.
Attributed revenue is a claim, not a measurement
Meta and Google both count the same order. Profflow reports what each platform claims, plainly labelled, and measures the channel against contribution — it does not add the claims together and call the total revenue.
03 / What it lets you do
What follows from getting Profit ROAS right.
Break-even after every variable cost
The return each euro of spend needs once VAT, goods, shipping and fees are paid.
Profit ROAS, not gross
Acquisition measured against contribution, not attributed revenue.
Channel winners and losers

Measured spend
Uses the spend posted by the ad account where it is connected.

[ Asked of the figures ]
Which channels are actually paying for themselves?
After every variable cost, €1 of spend has to bring €1.93 of sales to break even. In the sample month all three channels clear it; TikTok by the least, at 3.58×, leaving €102 after its own €120.
How Profflow reasons06 / How the figure is kept honest
The same four rules,
on every screen.
- Read-only, on every plan
Profflow observes the accounts it is connected to. It does not write an order, a price, a campaign or a payout back to any of them.
- Measured stays measured
A charge read from an account is labelled measured. Anything modelled — a forecast, a projection, a filled gap — is labelled as such on the screen it appears on.
- Every figure opens
Follow any number to the dated rows underneath it. A figure nobody can check is a figure nobody acts on.
- You approve
The product prepares a decision and shows the evidence. Nothing consequential happens until you say so.

Because VAT, cost of goods, shipping, packaging and fees all come out of the same euro before it pays for advertising. A line drawn from COGS alone sits far too low.
Measured where an ad account is connected; typed figures are used until then and are labelled as such.
No. Attributed revenue and business contribution are different signals and stay distinct.
The model works from spend and attributed revenue per channel; connected ad accounts add measured daily spend.
