Calc Bill POS by ShanApps

Running a shop, stall, or small business? You don't need a separate billing machine, a printer terminal, or an expensive POS system. Shan Calc Bill POS turns your Android phone or tablet into a complete billing counter — calculator, receipt printer, stock tracker, and customer credit book, all in one app.

It's built for how real shops actually work. Fast, offline, and practical.

WHAT YOU CAN DO WITH IT
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

⚡ Calculator + Live Billing Tape
Type your amounts like a regular calculator. Switch to billing mode and every line becomes an itemized bill entry — with item names, quantities, prices, and tax all sorted out automatically. No re-entering, no double work.

🖨️ Print on Any Bluetooth Thermal Printer
Pair once with any 58mm or 80mm ESC/POS Bluetooth printer and you're set. Bills print instantly — with your shop name, contact details, item breakdown, tax summary, and footer message. One tap and it's done.

💰 GST, VAT & Custom Tax on Each Item
Set tax rates globally or per item. Works with inclusive and exclusive tax modes. If some items are exempt (like certain food items), mark them and the app handles it automatically. Every receipt shows the exact tax breakdown.

📒 Customer Credit Book (Udhar / Khata)
Keep track of who owes what. Record credit sales, log cash or UPI payments, and see each customer's full transaction history. No more paper notebooks — everything is right here.

📦 Product Catalog with Stock Alerts
Save your commonly sold items with prices, codes, and default tax rates. When stock runs low, you get an alert. Checkout from the quick-tap grid without typing the same items every time.

📸 Digital Receipts via WhatsApp, SMS or Email
Don't have a printer around? Save the bill as an image or PDF and share it directly. Customers get their receipt on the spot.

☁️ Works Offline, Syncs When You Want
No internet needed for day-to-day use. All your data lives on your device. If you run multiple counters or want cloud backup, connect to a PocketBase server and sync across terminals.
