About UPTECH Smart Shop Management (Inventory - POS - Invoice)
UPTECH Smart Shop Management is an Electron desktop application that runs a complete retail or super shop operation: barcode point of sale with thermal receipts, inventory tracking with product photos, purchase orders, customer loyalty and credit, supplier payables, expense tracking and eight business reports. The system uses the shop owner's own Google Sheet as the shared database via an included Apps Script backend, so multiple PCs work on live data without a server to rent or maintain. Three PIN-protected roles (admin, manager, cashier) control access to sensitive functions. The same codebase also runs as a static website for browser-based demos.
Why UPTECH Smart Shop Management (Inventory - POS - Invoice)
What makes it better
than the alternatives
- 01
Google Sheets backend
Multi-PC shared data with zero server cost; shop owners control their data in their own Google Drive, synced via an included Apps Script Web App
- 02
Product photos in the sheet
Upload, auto-crop and shrink product images to ~5 KB thumbnails that sync through Google Sheets alongside SKU, barcode, cost and price
- 03
Thermal receipt printing
Silent 80/58 mm receipt printing from Electron's native print API; also generates A4 PDF invoices for email or archiving
- 04
Offline-first with outbox sync
Local JSON cache persists every transaction immediately; changes queue in an outbox and push to the sheet when online, with conflict-free last-write-wins merge
- 05
Zero runtime dependencies
Vanilla JavaScript with no framework, no bundler, no npm packages shipped; 9,496 lines of audited code in 144 files

Quality report
Manually reviewedHow to read the quality report
What this is. Every project on Vibe96 goes through an automated audit of its source code before a reviewer in Dubai checks it by hand. The score is out of 100; 75 is the minimum to be listed, and any single failing check blocks a listing regardless of the score.
- Security
- No real credentials in the code, every data-changing route protected, admin areas role-gated, no SQL built from user input.
- Code structure
- A developer can navigate and extend it: clear module boundaries, no giant files, little copy-paste.
- Docs & completeness
- The setup guide, example config, schema and required files the builder committed to are actually in the archive.
- Dependency health
- Packages pinned, no known critical vulnerabilities, no abandoned libraries in production paths.
- Build & deploy
- A clean machine can restore, build and start it by following the shipped instructions.
Warnings are problems that didn't block the listing; they stay visible here until a later version clears them. The audit reads the code — it does not run it — so always try the live demo before you buy. Lines of code are counted from the same audited archive.
Reviewer notes (5 minor)
Dev dependencies outdated; no runtime dependencies; no critical vulnerabilities; moderate duplication and some oversized files; module boundaries mostly sound. None of these stop the software from working; the developer has been told and improvements come in a future update.
