You're scaling ads with a ROAS that looks fine. You're quoting a day rate that feels right. But once you factor in fees, refunds, shipping, idle time — the margin tells a different story.
Billnode is a set of fast, honest calculators for operators who need to make a call — not a dashboard to log into.
Enter your ad spend, revenue, COGS, fees and refund rate. Get your real net margin, break-even ROAS, and a plain verdict on whether to scale or pause.
Start from COGS, add your margin target and marketplace fees, get the minimum price that keeps you profitable on every channel.
See exactly how many euros your refund rate burns per month — and what reducing it by 1% is actually worth.
Income target + weeks worked + real utilisation rate → the day rate you actually need to charge.
Quoted price vs. hours logged vs. your blended rate. Know before you invoice whether you made or lost money on a project.
Side-by-side: retainer vs project-by-project economics. Accounts for scope creep, payment timing, and overhead.
