The Challenge
The existing checkout couldn't support multi-currency transactions or modern payment methods, causing high cart abandonment among enterprise buyers.
Internal teams were fully allocated to core platform work and lacked Stripe integration expertise.
Our Approach
We scoped a fixed-price agency engagement with 2 backend, 1 frontend, and 1 QA engineer, led by a Fractional CTO.
The team worked in 2-week sprints with weekly demos, integrating Stripe Connect, webhooks, and a new React checkout flow.
The Outcome
New checkout live in 12 weeks with 22% conversion improvement and €2M processed in the first month.
Zero payment incidents post-launch with full documentation and knowledge transfer completed.
