Everything a retail shop needs
NodeDR POS ships all the core POS features in one Docker Compose stack — no plug-ins, no paid tiers, no feature gating.
Barcode-driven checkout
Scan to add items, scan again to bump quantity, press Enter to finalize. Unknown barcodes surface a clear toast — no register blocking. Works with any USB HID barcode scanner out of the box.
GST billing & compliance
Per-product GST rates with HSN/SAC codes. MRP is treated as GST-inclusive as required by Indian law — CGST/SGST are broken out on every receipt. Live GSTIN and PAN format validation built in.
Cash, UPI & card payments
Multiple payment methods at checkout — cash (with change calculation), UPI, and card. Mixed payment is supported. Payment method mix is visible on the sales dashboard.
Thermal receipt printing
Three print paths: browser print dialog (any CUPS/OS printer), server-side PDF download, or direct ESC/POS over USB — receipt cuts off the roll without a dialog. Auto-print after every sale is one setting toggle.
Loyalty & customer dues
Customers earn points on every purchase, redeemable at checkout. Udhaar (credit) sales track dues against a customer with full payment history. Top customers ranked by point balance on the dashboard.
Offline barcode generator
No barcode on a product? Generate a valid EAN-13 using the GS1 internal-use prefix range, or print a QR label — all client-side, no network call. Works fully offline.
Returns & exchanges
Look up any past bill by invoice number from the register, queue lines to return, and settle as a refund or fold straight into a new exchange sale. Returned stock auto-restocks. A unit can never be returned twice.
Inventory management
Scan to edit stock, auto-fill new product form on unknown barcode, low-stock dashboard alerts, per-product discount %, and an optional 'allow negative stock' mode to keep the register open when counts lag reality.
Sales dashboard & CSV export
Revenue trend, best sellers, payment method mix, top loyalty customers, and today's totals. One-click CSV export of full sales history. Searchable invoice history with reprint from any past sale.
Staff accounts & roles
Admin and cashier roles. Cashiers run the register; admins manage staff, settings, inventory, and exports. Bcrypt-hashed passwords and HttpOnly JWT sessions.
Works on LAN tablets & phones
Access at http://machine:1994 from any device on the shop network — the nav collapses to a slide-out drawer on mobile. No per-device install needed.
Zero external calls at runtime
Once the Docker stack is up, the app never phones home. No analytics, no telemetry, no cloud dependency. Your sales data never leaves the shop.

Built for shops everywhere
NodeDR POS supports 20+ currencies out of the box and works with any tax system — VAT, GST, sales tax, or none. Switch currency in Settings and every screen, receipt, and report adapts instantly.
+ any currency your business needs — fully configurable
Any device on your network
NodeDR POS runs in any browser — desktop or mobile. Open it from the shop computer, a counter tablet, or a phone on the same Wi-Fi. No app installation, no internet connection.
We’re building installable native apps so you can launch NodeDR POS without a browser tab or terminal — double-click to open, auto-start on boot, system tray icon.
How it works
One port exposed. The frontend proxies API calls to the backend over the internal Docker network — the backend never touches your LAN.

SQLite (Docker volume)
Your data never leavesOne port, one origin
Port 1994 is the only exposed port. No CORS complexity — session cookies are first-party and the API isn't exposed on your network.
LAN access built in
Any tablet or phone on the same network can open the register in a browser. No per-device app or install needed.
Data in a Docker volume
SQLite lives in the nodedr-pos_data named volume. Containers restart and rebuild; your data stays untouched.
How NodeDR POS stacks up

Up and running in under 10 minutes
All you need is Docker. The installer handles the rest — no manual database setup, no config files to edit.
Clone and run the installer
One command clones the repo and runs the installer script. It checks for Docker, builds both images, starts the stack, and prints the URL when ready.
git clone https://github.com/Raktim94/nodedr-pos.git && cd nodedr-pos && ./install.sh
Complete guided onboarding
First launch shows a setup wizard: create your admin account, enter your shop name, address, currency, and optionally GSTIN. Takes about 2 minutes.
# Open in browser: http://localhost:1994
Add products and start selling
Add inventory by scanning barcodes or typing. Then go to POS, scan items to add to cart, select payment method, and print the receipt. Done.
# Access from any LAN device: http://<your-machine-ip>:1994
./install.sh — it rebuilds images and restarts the containers. Your data in the Docker volume is never touched.What’s coming next
