AT A GLANCE

An e-retailer partnered with Zemoso Labs when its existing payment system no longer met the needs of its growing and rapidly evolving business. They needed to support new use cases, improve merchant experience, and service customer needs differently. They decided that an in-house payment system that adapts and scales faster was the way to go. The client chose Zemoso for our ability to execute product development collaboratively with their team, leveraging structured frameworks and mature engineering practices. Zemoso partnered with them on specific go-live elements that were mission-critical, had hard deadlines, and required a lot of quick discovery and solutioning.

CORE CHALLENGEs

The e-retailer's existing payment system was complex and expensive to maintain, lacked dedicated features like subscription-based billing for evolving customer segments, and relied on periodic batch processing that delayed real-time revenue realization and drove up bad debt. Re-architecting it meant navigating a codebase heavily dependent on the existing architecture, plus tightly coupled third-party integrations and plugins, all while keeping the business running without disruption.

the engineering approach

We helped our client succeed by leveraging our battle-tested innovation and execution frameworks, proactively managing risks throughout the process. 

We collaborated with stakeholders consistently through knowledge transfer sessions, backlog grooming, sprint planning, and sprint demos practices. These played a pivotal role in understanding customer requirements and adjusting to scope changes iteratively.

  • System re-architecture: A pure microservices architecture, in its current form, would not be able to deliver on the configurability and adaptability requirements of the clients. We augmented the existing structure by redesigning their data stores. This enhancement improved system adaptability and made it easier to debug and identify points of failures quickly. 
  • Migration roadmap: We created a launch and migration roadmap that allows the new and old systems to work parallelly, interact with each other, until the full transfer was complete.
  • Accelerated deployment: Zemoso accelerated development timelines, enhanced productivity, and facilitated the smooth deployment of the modernized system.
bottom line

Zemoso's expertise in application modernization empowered the client to replace its rigid, expensive payment system. As a result, the client can roll out new business models, run real-time invoice reconciliations, and deliver a better merchant and buyer experience.
