The company develops its platform, PrimeRx, which serves a diverse range of pharmacy settings, including retail pharmacies, specialty pharmacies, long-term care facilities, compounding pharmacies, health systems, 340B programs, mail-order pharmacies, and physician offices. PrimeRx helps build and sustain healthy communities by integrating patient, provider, payer, and carer data. One of the firm's key strengths is its user-friendly interface, which allows pharmacy staff to learn and navigate the system.

These features are designed to streamline pharmacy operations, improve efficiency, and enhance the overall patient experience. PrimeRx generates revenue through licensing and subscription fees for its pharmacy management software platform, which supports prescription processing, workflow management, inventory, compliance, point‑of‑sale, and patient engagement. Revenue is derived from recurring contracts with independent pharmacies and pharmacy chains using on‑premises and cloud‑based.
