Exoft helped a US healthcare technology company develop and scale a B2B marketplace for buying and selling surplus medications. Our work covered full-stack development, payment integrations, pharmaceutical traceability, an AI assistant, QA, and DevOps. We also introduced AI-assisted development and testing practices to help the team deliver new features faster. During the partnership, the client’s network grew from 100 to over 2K pharmacies, while the platform expanded to serve larger pharmacy operators and healthcare organizations.

Client: US Pharma Technology Company

Our client is a US pharma & healthcare technology company operating a B2B marketplace where pharmacies buy and sell medications.

They help with a specific pharmacy challenge: excess inventory. Unsold medications tie up capital and risk expiring, while other pharmacies need the same products but must buy them from wholesalers at higher prices.

The client’s platform connects these pharmacies, letting sellers recover money from surplus inventory and buyers source medications at competitive prices.

Challenge: Expand a Pharmacy Marketplace in a Steep Competition

The client wanted to turn its early-stage pharmacy marketplace into a scalable, competitive product. That introduced some challenges they needed to solve together with Exoft team:

  • Pharmaceutical regulations. Transactions required drug traceability records, pharmacy verification, and trading restrictions that differed across US states.
  • Payment processing. Changes in payment providers forced the client to migrate its payment system twice, with only one month available for the second migration.
  • Growing product complexity. Larger pharmacy clients needed more advanced purchasing workflows, administrative controls, and integrations.

Cooperation: A Long-Term Technical Partnership

Exoft joined the project in 2021 and scaled the team in 2023, when the client secured its first investments. As the product grew, our team scaled from a few developers to approximately 19 specialists covering frontend and backend development, QA, DevOps, AI, and full team management.

We work closely with the client’s management team to understand business needs and turn customer feedback into features and improvements. But it’s not just development that we cover. Exoft takes part in technical planning, recommends implementation approaches, and adjusts priorities to meet critical business deadlines.

Quick Recap of Scope:

  • Product Development: Expanded the marketplace with new modules and features based on pharmacy needs and customer feedback.
  • Payment Integrations: Migrated between payment providers, covering highly complex business verification and transaction processing. Did so faster than all competitors, winning a significant market share as a result.
  • Pharmaceutical Compliance Implementation: Implemented EPCIS-based drug traceability, state-specific restrictions, and transaction rules.
  • AI Development: Built an AI assistant that helps users search medications and complete marketplace tasks quicker (lowering the learning curve).
  • Quality Assurance: Established manual and automated testing processes to improve product quality and catch regressions.
  • DevOps: Set up CI/CD pipelines, automated checks, and streamlined deployments.
  • AI-Assisted Engineering: Improved development workflows, task documentation, and AI-assisted coding practices to support faster delivery (3x-5x faster that with traditional engineering for different tasks)

Solution: Pharmacy Marketplace with Integrated Payments, Traceability, and AI

Pharmacy-to-Pharmacy Trading

The application supports medication listings, product searches, purchasing, payments, shipping, and returns within one system. Additional functionality includes:

  • In-platform messaging between pharmacies to discuss orders and availability.
  • Shipping integrations with tracking statuses visible to both buyers and sellers.
  • Barcode scanning through mobile cameras and external scanners.
  • Transaction history, financial information, and administrative controls.
  • Payment recovery workflows to handle failed operations or issues with external services.

Pharmaceutical Traceability and State-Specific Rules

Our engineers developed functionality for processing and generating EPCIS (Electronic Product Code Information Services) records. These records support medication traceability by documenting product information and transfers between trading partners.

The system also needed to account for differences between US states. Certain products and transactions are subject to restrictions depending on the location and status of the buyer or seller. We implemented state-based rules and transaction restrictions to help the platform enforce them.

AI Assistant for Pharmacies

To simplify common operations, we developed a Claude-powered AI assistant connected to the marketplace through MCP and internal APIs. Instead of manually navigating multiple screens, pharmacy representatives can use natural language to:

  • Find medications available for purchase
  • Check product information and compare available prices
  • Help create purchase orders and medication listings
  • Retrieve information about supported marketplace operations

The assistant follows existing user permissions and only accesses approved platform functions. Three engineers developed its first working version in approximately one month, ahead of an industry conference.

Results: Winning the Market Competition

By scaling the development team and releasing new features quickly, we helped the client strengthen its position in the pharmacy-to-pharmacy surplus inventory market. During our engagement, the platform’s network grew from approximately 100 to over 2K pharmacies.

  • 10x+ year-over-year growth for the company
  • Business continuity during payment changes, which helped win over new customers
  • AI assistant launched in approximately 1 month, demonstrated on time for the largest industry conference
  • 3x faster development and releases with AI-assisted coding and automated pipelines

As the business expanded, we continued adding new capabilities and adapting the platform to support larger pharmacy operators and healthcare organizations. As the platform expanded, the client publicly reported month-over-month transaction volume growth of 50% in mid-2026.
