The problem
Growth that never reaches profit
Revenue and orders grow, profit doesn’t. The data sits in separate places, the work is manual, and decisions are made a month late.
Last month drives the decisions
- You only see profit in the accountant’s report, a month later
- Every system reports its own number — none of them agree
- Discounts, returns and write-offs eat margin unnoticed
- Reporting is manual, lives in spreadsheets and in one person’s head
- Growing means spending more and hoping
Today’s number drives the decisions
- One view shows real contribution margin every day
- Sales, costs, logistics and returns in a single model
- Every product, channel and order ranked by profit
- Reporting arrives automatically, with no manual work
- Growing means knowing which euro comes back
How we work
Three layers, one rhythm
We don’t sell software and we don’t build a platform. We assemble the tools that already exist, configure them around your business and operate them — and when the piece you need doesn’t exist, we build it.
- LAYER 01
Data — one source of truth
We pick the right tools for your business and connect them into a single view. Licences stay in your name, access stays with you.
- Sales, costs, ads, logistics and returns in one model
- CM1 / CM2 / CM3 by product, channel or order
- Automated data flows, no manual exports
- LAYER 02
Method — where profit leaks
A fixed way to find and rank leaks. Every leak gets a euro impact and a cost to fix, so priority is calculated, not guessed.
- Leak map: pricing, channels, funnel, operations
- Every leak with € impact and an effort estimate
- Priority = impact divided by cost
- LAYER 03
Monthly cycle — a decision, not a report
The same rhythm every month: measure, decide, build, verify. A report is not the output — the output is a number that moved.
- Start of month: € impact of the previous cycle
- During the month: automations and tests shipped
- End of month: what moved, what didn’t, and why

We don’t reinvent the wheel
The tools that do most of this work already exist, and they do it better than any agency building from scratch. Our value is the selection, the configuration and the operating — plus the last piece we build ourselves.
As a Klar agency partner we set up and manage your account from one place. Data stays in Europe, under ISO 27001 and GDPR requirements.
Licences stay in your name. The account, the data and the access belong to you even if the engagement ends. We tell you licence costs up front, and if another tool fits your situation better, we recommend that instead.

How we implement our partner toolsOutcome
What this system actually delivers
These are customer stories published by Klar — ecommerce brands that moved decision-making onto contribution margin. Same tool and same method we start with at your company.
From negative contribution margin to profitable new-customer acquisition — pricing, channel truth and a margin view pulled into one model.
- CM3 up 256%
- Customer acquisition cost (CAC) down 23%
- Average order value (AOV) up 21%
Incrementality measurement fixed: ad spend moved to the channels that actually produce profit, then the same model was rolled into a new market.
- CM3 up 70%
- Revenue up 55% YoY
- Customer acquisition cost (CAC) down 27%
- Successful expansion into Spain on the same model
Black Week budget more than doubled without sacrificing margin, because decisions were made on contribution margin instead of platform ROAS.
- CM2 up 120% YoY
- Black Week revenue up 327%
- ROAS improved 35% on +216% budget
- New customers up 44% YoY
The numbers come from customer stories published by Klar and were achieved by Klar together with a partner agency. They are not Efectivum’s own projects — they show what the same profit-led method produces.

Fit
Who this is for — and who it isn’t
An honest filter before the call. Both sides win when a bad fit shows up before the contract, not after it.
A fit if
- Revenue is €1–10M and growth is limited by margin or process, not demand
- You have a P&L, but decisions aren’t made from it
- The owner or a decision-maker is on the call
- You’re willing to change pricing, assortment or process — not just ads
Not a fit if
- You only want a media buyer who buys traffic cheaper
- Growth has to arrive next month without touching the process
- Access to the data isn’t possible or won’t be granted
- Revenue is under €1M — start with the free diagnostic instead

Calculate profitWho does the work
I don’t sell channels. I build profit logic.
I’ve spent twenty years in ecommerce — inside stores and as an outside partner. The picture is almost always the same: revenue grows, the dashboard is green, and at the end of the month there’s no more cash in the account than last year.
The reason is nearly always identical. Decisions are made on platform ROAS instead of contribution margin. Ads, pricing, logistics and repeat purchase live in separate spreadsheets, and nobody sees which order actually makes money.
My job is to assemble that picture: one calculation, one truth, clear next steps. If the numbers say we can’t improve your profit, I’ll tell you that on the first call.
