Meridian is a Windows desktop system for a shop or small warehouse: stock and stocktaking, purchases, sales, a scanner-driven cash desk with 20+ discount types and loyalty rules, customer cards and documents.

• The database runs on your own PostgreSQL server (version 12 or newer)
• Several workstations share one database, with per-employee roles and permissions
• 10 seats free forever; 25, 50 and 100 seat packs are one-time purchases with a year of updates, and the software keeps working after support ends

Windows 10/11 (x64). The interface is currently English and Russian.
