Case Study: JamDoughnut boosts Pay by bank conversions with TrueLayer

JamDoughnut High-converting Pay by bank option wins over shoppers

JamDoughnut, a UK cashback and rewards app, needed a fast, reliable open banking payment method to support its high-volume checkout flow, especially for supermarket shoppers paying in a hurry. As the business scaled and handled around one transaction per second, it turned to TrueLayer for a Pay by bank solution that could deliver speed, simplicity, and dependable performance.

TrueLayer implemented JamDoughnut’s Pay by bank checkout using its hosted payment journey, along with verification and payments APIs for refunds. The result was over 90% of payments being processed through Pay by bank, with more than 90% conversion on the first attempt and about 85% of transactions coming from returning customers. TrueLayer also helped JamDoughnut with integration support and real-time reporting, giving the team confidence to keep improving the customer experience.
