Expanding Retail Payment Integration: Developing a Custom Pharmacy Application

Bridging Retail & Pharmacy Systems for Seamless Care

As the lines between grocers and pharmacies continue to blur, grocery retailers with in-house pharmacy networks are expected to deliver seamless, end-to-end healthcare experiences. From walk-in prescriptions to mail-order fulfillment, every touchpoint must be tightly integrated. Yet when core workflows like payment processing are managed through external vendors or disconnected systems, it leads to operational inefficiencies, fragmented customer experiences, and unnecessary costs.

That was the situation facing a national grocery retailer with an in-house pharmacy network. While their EasyFill Pharmacy Retail Network (EPRN) application handled core services like sales, customer tracking, and order fulfillment, their payment systems remained disconnected, managed through an external vendor and a separate tool for postal prescriptions. To provide a more unified customer and pharmacist experience, they needed a custom-built payment module embedded directly into EPRN. Aditi was brought in to design, develop, and integrate the solution.

The Challenge

Disparate Payments, Limited Visibility

The client’s in-store and mail-order prescription services were operationally effective but technically fragmented. Payments were processed through a third-party application that didn’t connect with EPRN, creating delays, manual workarounds, and a lack of real-time visibility into the end-to-end transaction flow.

The client needed to enhance the EPRN platform to support native payment capabilities, removing vendor dependency and streamlining both in-store and postal workflows. The new functionality had to integrate smoothly with the existing infrastructure while remaining agile enough to accommodate evolving requirements during development.

The Solution

Secure & Integrated Development

Aditi deployed a team of developers to handle the end-to-end build and deployment of a new Pharmacy Payment Module—seamlessly integrated into the existing Java-based EPRN environment.

  • Secure, Scalable Architecture:
    The team leveraged tools including Apache Subversion (SVN) for version control, WebSphere Application Server (WAS) for deployment, and Oracle 10g/XML for backend data management. Supporting technologies like Eclipse, JUnit, SoapUI, PuTTY, and Apache CXF ensured robust application development and testing.

  • Flexible, Collaborative Development:
    Aditi embraced an iterative approach, managing ongoing change requests and continuously performing unit and integration testing to ensure functionality and stability. Throughout the process, Aditi maintained a centralized server using WinSCP/FileZilla for real-time updates and deployment readiness.

The Outcome

Empowering Seamless Transactions

The new Pharmacy Payment Module transformed the client’s ability to manage transactions directly within EPRN—removing the need for third-party platforms and eliminating disconnects between systems.

  • Fully Integrated Workflows:
    The application now supports native payment processing alongside order fulfillment and customer tracking, improving speed, visibility, and consistency across both in-store and postal operations.

  • Enhanced System Agility:
    The module was built to accommodate evolving business needs, with support for frequent change requests and rapid QA iterations throughout development.

  • Seamless Knowledge Transfer:
    At project close, Aditi completed a comprehensive knowledge transfer (KT), including detailed documentation and walkthroughs for application usage, future enhancements, and issue resolution—ensuring the client’s internal team could maintain long-term success.
