Primer, the unified infrastructure for global payments, has teamed up with BUT, the French retail giant, to strengthen its online payment stack, optimize performance, and reduce complexity—all while delivering an enhanced customer experience.

As part of this partnership, Primer has expanded its capabilities to support BUT’s online marketplace. This enables the retailer to manage all payments through a single, unified infrastructure. 

Strengthening BUT’s payment stack

To meet the demands of its expanding ecommerce business, BUT needed to build resilience into its payments to mitigate against the risk of any single payment processor having downtime. With Primer, BUT can add additional payment service providers (PSP) to its payment stack with minimal engineering effort.

In addition to this, BUT will be adding new payment methods to its checkout. With Primer, these can be added to the checkout with no additional development effort and help BUT enhance the customer experience, drive higher conversion rates, and meet the diverse needs of its shoppers.

Optimizing performance

As part of its payment transformation project, BUT will leverage Primer’s suite of optimization tools to enhance its payment performance. One of the major enhancements includes 3DS optimization, notably offering better support for Cartes Bancaires transactions and improving authorization rates in the French market.

BUT will also leverage Primer Fallbacks to recover potentially lost transactions by automatically retrying failed payments through alternative PSPs. This solution is invaluable in recovering lost revenue, making it a crucial component for ensuring higher success rates in payments.

Additionally, fraud protection has been integrated through Forter, providing an added layer of security and helping BUT minimize chargebacks and fraudulent activity. With Primer Workflows, BUT can trigger these fraud checks directly, dynamically routing transactions based on risk signals without additional engineering effort.
