We are excited to announce a new partnership between Kustom, one of the leading checkout and payment providers in the Nordics, and Pertento, the experimentation platform built for modern e-commerce.
Through this partnership, Kustom will use Pertento to help merchants measure the real business impact of their checkout solutions. The goal is simple. Replace assumptions with statistically sound experiments that show how payment experiences affect conversion, revenue, and customer behavior.
Together, we continue our ambition of making payment performance transparent, measurable, and driven by data.
Why payment experiments matter
The checkout is one of the most business-critical parts of the customer journey. Even small differences in the payment experience can influence:
- Checkout conversion rate
- Completed transactions
- Average order value
- Payment method adoption
- Customer satisfaction and repeat purchases
Yet payment providers are often evaluated based on pricing, features, or industry benchmarks rather than how they actually perform for a specific merchant.
The reality is that no two stores are identical. Customer behavior, product mix, brand trust, and purchase intent all influence which checkout solution performs best.
With experimentation, merchants can answer that question using their own data.
Using Pertento, merchants can compare different checkout solutions or payment configurations in controlled experiments while everything else in the customer journey remains identical. This makes it possible to isolate the true impact of the checkout on conversion, revenue, and overall business performance.
Full conversion transparency without personal data
Measuring checkout performance accurately has traditionally been difficult. Many analytics and experimentation tools rely on cookies or personal identifiers, meaning a significant portion of conversions may be lost due to consent requirements or tracking limitations.
Pertento takes a different approach.
Because the platform does not rely on personal data, experiments capture the complete set of conversions regardless of consent choices. Merchants therefore gain an accurate understanding of how checkout changes affect revenue and conversion.
For Kustom and its merchants, this means decisions can be based on complete data rather than incomplete attribution.
Better decisions through experimentation
Whether evaluating a new checkout solution, introducing new payment methods, or optimizing an existing payment flow, experimentation provides an objective framework for decision making.
Instead of relying on assumptions or external benchmarks, merchants can validate changes with real customer behavior and measurable business outcomes before rolling them out to everyone.
This reduces risk while ensuring that checkout improvements genuinely improve performance.
Raising the standard for payment evaluation
Payment providers have traditionally been difficult to compare objectively because every merchant’s business is different.
By combining Kustom’s checkout platform with Pertento’s experimentation capabilities, merchants gain a practical way to evaluate checkout solutions using controlled experiments and statistically reliable results.
We believe payment decisions should be based on evidence, not assumptions.
This partnership represents another step towards a more transparent e-commerce ecosystem where merchants can confidently optimize one of the most important parts of the customer journey using real performance data.
We look forward to helping merchants unlock measurable improvements together with Kustom.
