About this app

Proteus POS turns an Android phone or tablet into a register for your Proteus ERP account. Sell from your live product catalog, take cash and card payments, print receipts, and keep selling when the internet drops.

A Proteus ERP account is required. Sign in with your company account and staff login.

RING UP SALES FAST
• Browse your catalog by category, search by name, or scan a barcode with the camera
• Apply line-item and whole-order discounts
• Look up customers and attach them to the sale

TAKE PAYMENT YOUR WAY
• Cash, with change calculated for you
• Card payments through a connected card reader, with tips
• Gift cards
• Split one sale across several payment types

BUILT FOR RESTAURANTS
• Open tabs and checks, named or by table
• Seat numbers, courses and special instructions sent with each order
• Item modifiers with surcharges
• Items 86'd in the ERP show as unavailable on the register right away

COMPLIANCE BUILT IN
• ID scanning and age checks before a sale
• Daily purchase limits enforced at checkout
• Package tracking for inventory that has to be accounted for item by item

KEEPS WORKING OFFLINE
Products, prices and settings are stored on the device. If the connection drops, sales are saved on the register and sent to Proteus ERP automatically when it comes back. From the Transactions screen you can see every sale, retry one that did not go through, and reprint any receipt.

RECEIPTS AND CASH DRAWERS
• Print to a networked Epson receipt printer, or to any printer through Android's print dialog
• Assign the register to a location and cash drawer so every sale lands in the right place

EVERYTHING STAYS IN SYNC
Sales, inventory and customers go straight into Proteus ERP, so the back office, reports and stock levels are always current. There is nothing to export or re-key.
