Real attribution. A price you can see
Most tools make you choose: traceable numbers or a fair price, local support or every feature. Here is how BOLZ Base fits in.

Keep GA4. Decide with BOLZ Base
GA4 is free and good at what it does. But it models what it cannot see, reports inside Google's own world, and does not know your refunds, your VAT or your Bol.com spend.
Orders, not estimates
BOLZ Base counts the orders from your shop and links them to visits, instead of modelling conversions.
Every platform's spend
Google, Meta, Bol.com and Etsy side by side, so ROAS is calculated the same way everywhere.
Built for the morning
Three answers before you scroll, instead of a report you have to build first.
