Calculate what your own White Label CSS earns every month

A CSS is a Google-approved price comparison service through which merchants can run their product data in Google Shopping. Instead of booking ads through Google Shopping directly, they run through the CSS as an intermediary. Nothing visible changes for the merchant — the ads appear in the same places — but the way click prices are settled does. The CSS operator maintains the connection to Google and is the approved partner on Google's side.

With white label you use an existing, Google-approved CSS infrastructure while appearing entirely as your own provider: your brand, your domain, your panel and your invoice to the merchants. Technology, the Google connection and day-to-day operations stay with the provider in the background. You handle sales, pricing and customer care — the parts that actually earn you money.

It is a classic reseller calculation: you pay a fixed monthly fee for the white label CSS and resell access to your merchants, for example at €39 per merchant per month. The difference between your income and that fixed fee is your profit. Because the fee doesn't grow with volume, your margin increases with every additional merchant while your cost stays flat — the effect becomes clearly visible once you pass a couple of dozen merchants.

That depends on the provider. Many white label models use a fixed monthly fee with no merchant limit, so mathematically it makes no difference whether you serve 5 or 500 shops. Others tier by merchant count or data volume. Clarify this before you start, because a limit or a tier changes your calculation and therefore the price you can offer your own customers.

This also varies by provider. The model worth looking for is a fixed monthly fee with no share of your selling price and no extra per-click or per-account fees. Only then do you know your costs upfront and can quote reliable prices to your merchants. With revenue-based models the provider's cut grows with your success, so check carefully what the monthly fee actually includes.

Usually yes. Merchants running through a CSS often pay up to 20% less for Google Shopping clicks than via Google Shopping itself, because bids are settled differently. How large the saving actually is depends on the vertical, the competition and the campaign structure. For you this is the strongest sales argument: the merchant often saves more on click costs than they pay you each month.

No. Approval as a Comparison Shopping Service sits with the CSS operator whose infrastructure you use under white label. You don't go through Google's review process, don't have to run a comparison platform and don't have to meet Google's technical requirements yourself. That shortens the start considerably — instead of months spent on approval you go straight to brand, pricing and your first merchants.

Brand, domain and the technical setup are clarified first, followed by the panel, invoicing and connecting the first merchant accounts. In practice your CSS is usually ready within a few days. The real time factor is rarely the technology but your own preparation: price list, contract documents and a clear offer for the merchants you want to approach.

Existing campaigns stay in place. Switching CSS only affects which service serves the Shopping ads, not the structure of the Google Ads accounts, campaigns or bidding strategies. History and optimisation data are not lost. For the merchant the move is therefore an administrative step, not a rebuild of the account.

Revenue is your price per merchant multiplied by the number of merchants. Your provider's fixed monthly fee is subtracted from that, and the result is your profit. Both are shown per month and — multiplied by twelve — per year. Individual extra costs such as marketing, support effort or taxes are deliberately not included; the calculation shows the pure margin of the model. For csspartner.io the yearly figure also includes the one-off €499 setup, so it shows the first year. If you pay yearly, you pay ten instead of twelve monthly prices; the calculator conservatively assumes monthly payment.
