PharmaOS — Point of Sale
THE OPERATIONAL CHALLENGE
Pharmacy workflows are deeply interconnected.
Daily pharmacy operations involve more than checkout. Products, stock, suppliers, receiving, pricing, sales and financial activity continuously affect one another. PharmaOS was structured to bring those workflows into a consistent operational model.

THE SOLUTION
One operational platform instead of disconnected workflows.
PharmaOS organizes the major pharmacy workflows behind clear modules while preserving the relationships between products, inventory and transactions.
Inventory Control
Stock visibility, inventory movements and operational controls built around a centralized inventory boundary.
Purchasing
Supplier purchasing workflows connect receiving activity with stock and operational records.
Pricing & Promotions
Dedicated pricing workflows separate commercial pricing decisions from core product and inventory data.
POS & Sales
A transactional point-of-sale workflow designed for fast daily pharmacy sales operations.
Cashbox Operations
Cashbox and financial-shift workflows provide stronger operational control over daily transactions.
Reporting
Operational reports turn purchasing, stock and sales records into useful management visibility.
Operational History
Historical records preserve visibility across important product, pricing and transactional activity.
01 / PRODUCT & INVENTORY
A structured foundation for pharmacy stock.
Product management and inventory are treated as connected but distinct operational concerns. This makes it possible to maintain product identity while tracking the stock activity that happens around it.

Movement-oriented stock records
02 / PRODUCT MASTER
Products modeled for operational use.
The product master provides a dedicated place for managing the commercial and operational identity of pharmacy products instead of embedding that information directly inside sales screens.
Structured product records
Pricing relationships
Controlled operational data
03 / PURCHASING
Purchasing connected to stock operations.
Purchasing workflows provide structured visibility into supplier activity and receiving, helping maintain a clear relationship between incoming goods and inventory records.

04 / PRICING
Pricing managed as its own operational domain.
Pricing and promotions are separated from basic product records, providing a clearer foundation for commercial rules and historical pricing activity.

ENGINEERING FOCUS
Built around business rules, not just screens.
Inventory integrity
Stock-changing workflows are structured around controlled application boundaries rather than independent UI mutations.
Transactional workflows
Purchasing, sales and financial operations require coordinated changes across multiple records and business rules.
Local operational reliability
The architecture supports local operation with application data persisted directly in SQLite.
