Providers differ in monthly costs, supported markets, onboarding, reporting, support quality and cancellation terms.

Here is a comparison based on public information from both provider websites, focusing on key details for small and mid-sized merchants.

Both providers do the same core job

All certified Google CSS Partners use the program Google introduced after the 2017 EU antitrust decision. The 20% bidding-power advantage comes from removing the internal margin of Google Shopping.

Choosing between CSS partners comes down to pricing, service levels and operational fit. The features below distinguish both providers in daily use.

Pricing model

csspartner.io costs a flat fee of €29 per month with no setup fees, revenue shares or minimum spend requirements. You can cancel anytime.

Producthero costs €39 per month plus €19 per additional country. A merchant in three countries pays roughly €77 per month (€39 + 2 × €19) through a subscription model.

A flat fee keeps costs predictable as ad spend grows if you only want the 20% CSS bidding-power advantage. Tiered plans suit merchants who also want feed optimisation and bid automation tools.

Supported markets

Both providers cover all Google Shopping CSS markets across the EEA, Switzerland and the UK, currently 21+ countries. A single CSS account covers every supported market.

Either provider can support your entire European Shopping setup across multiple EU markets. Check their website country lists to verify niche market coverage.

Onboarding and migration

Switching CSS partners retains your full Google Ads campaign history. Your Merchant Center sub-account links to the new CSS while keeping existing campaigns, smart-bidding signals and conversion data intact.

csspartner.io completes the guided re-linking within a few business days. Producthero provides managed onboarding via its dashboard alongside self-service linking options.

Switching causes zero downtime when done correctly, allowing your campaigns to run without interruption during the move.

Reporting, support and extra tooling

csspartner.io provides direct Merchant Center linking alongside personal email and phone support from certified Google CSS specialists. You continue working entirely within your standard Google tools.

Producthero includes a dedicated dashboard with feed insights, product-level reporting and higher-tier optimisation tools. Support runs via dashboard and email, with enterprise consulting available.

A lean service like csspartner.io adds minimal overhead if you already manage Shopping campaigns in-house or through an agency. Producthero provides extra built-in tools through a tiered platform.
