Pharmacy point of sale

In development

An offline-first POS for pharmacies. Everything runs on the shop's own network, so a dropped internet connection doesn't stop sales. The cloud is an add-on, not a dependency.

Counter PCsElectron thin clients
Shop serverNode.js + PostgreSQL
Owner dashboardCloud
  • A single installer sets up Node.js and PostgreSQL on the shop's server
  • Counter machines run Electron thin clients over the local network
  • Phase 2 adds a cloud dashboard so the owner can follow the shop remotely
