The problem

Tạp hóa and small workshops track stock in their head or a shared notebook. Cloud inventory SaaS is monthly-priced and needs internet the shop doesn't reliably have.

The solution

• Add/edit products with stock codes; every nhập/xuất is logged with reason and time
• Rows below the alert level turn red and the status bar tells the owner it's ordering time; trying to sell more than in stock is blocked
• CSV export with Excel-friendly Vietnamese (UTF-8 BOM); full in/out history window

Result

Real desktop software, zero pip installs, data in one .db file — the honest version of "phần mềm quản lý kho" for a shop that just needs stock tracked, not an ERP.
