View source →Built around the scan.
Every item has a barcode or a printed QR label. Point your phone, scan, and the system handles the rest.
Scan
Camera-based barcode and QR reading. Factory UPC or self-printed SKU label. No dedicated hardware needed.
Track
Every check-in and check-out is an immutable transaction. Atomic database updates — no conflicts when multiple staff scan at once.
Alert
Per-item low-stock thresholds. When quantity drops below the line, it shows up on the reorder list automatically.
Report
Full inventory, reorder list, category summary. Print or save as PDF. Activity log shows who moved what and when.
What's in the box.
Barcode + QR Scanning
Uses the device camera. Reads factory UPC and self-printed QR labels. No app install — runs in the browser.
Atomic Stock Updates
Database-side increment/decrement. Multiple staff scanning at the same time won't clobber each other's changes.
Activity Log
Every movement is an immutable transaction row. Who checked what in or out, when, how many. Full audit trail.
Label Printing
Generate QR labels for items without factory barcodes. Auto-assigned SKU codes. Print and stick.
Low-Stock Alerts
Set a threshold per item. The reorder report surfaces everything that needs restocking with suggested quantities.
Self-Hostable
Supabase is open source. The whole stack runs on a mini-PC if you want it to. No vendor lock-in.
