The best POS billing app for SUNMI devices
SUNMI sells the terminal. It does not sell your shop software — you choose that. MCPOS Cloud turns a SUNMI handheld or desktop terminal into a complete point of sale: billing and tax invoices, orders, purchases, stock, accounting, staff, e-invoicing and AI insights, printing straight on the built-in printer and working with no internet.
Quick answer
Yes — MCPOS Cloud runs on every Android SUNMI terminal, from the V2 and V2s PLUS handhelds to the T2, T3 PRO and D3 MINI counter machines. Install it from Google Play, create your business, and bill in minutes.
The SUNMI built-in printer appears as a paired Bluetooth printer called InnerPrinter, so MCPOS prints 58 mm and 80 mm receipts, kitchen tickets and barcode labels on it with no extra driver app. Billing keeps working with no internet and syncs when the SIM or Wi-Fi comes back.
How to put MCPOS on a SUNMI terminal
- Install the app. Open Google Play on the terminal and install MCPOS Cloud. If the terminal has no Play Store (some payment terminals ship with the acquirer's own app market), write to us and we will send the APK for your model.
- Create your business. Sign up free inside the app, or on mcpos.mycodlabs.com, and add your products, taxes and outlet.
- Pick the printer. Settings → Printers. On SUNMI, pick the paired Bluetooth printer named InnerPrinter — that is the printer inside the terminal.
- Start billing. Scan or tap an item, take cash, card, UPI or credit, print the bill. The same business opens on the owner's phone, the back-office computer and the web.
MCPOS needs Android 6.0 or newer and about 150 MB free. It bills with no internet at all and syncs when the terminal gets Wi-Fi or a SIM again — which is what most SUNMI terminals are used for.

Printing bills on SUNMI
This is the part people worry about, and on SUNMI it is the easy one. SUNMI exposes the built-in thermal printer as a Bluetooth device called InnerPrinter, already paired at the factory. In MCPOS you go to Settings → Printers, add a Bluetooth printer, choose InnerPrinter, set 58 mm (handhelds) or 80 mm (T2 / T3 counter machines) and print a test bill. No driver app, no cable, no extra licence.
The same printer prints your kitchen tickets (KOT), the ZATCA or UAE e-invoice QR code, and barcode labels from the MCPOS Label Studio — labels print as a bitmap, so Arabic, Hindi and Malayalam come out exactly as they look on screen. A second printer in the kitchen or the back office can be added over Bluetooth, USB or the network at the same time.
What you can run on a SUNMI terminal
A SUNMI terminal is a small Android computer with a printer attached. Once MCPOS is on it, it stops being a billing machine and becomes the whole back office of the shop:
Billing & invoices
Barcode or touch billing, held bills, split payment, cash / card / UPI / credit, tax invoices, 80 mm and 58 mm receipts and A4 invoices, sales returns and refunds.
Orders & tables
Take-away and dine-in orders, tables and floors, KOT printing to the kitchen, split bills, service charge and tips, QR menu ordering (Restaurant plan).
Purchases & suppliers
Purchase orders, goods receipt, purchase returns, landed cost, supplier dues and payments — so your cost price and profit are real, not guessed.
Stock & inventory
Batches and expiry, variants and units, racks, multi-warehouse stock, transfers, adjustments, stock value and a full stock ledger.
Accounting built in
Every bill posts itself: ledgers, journal, trial balance, P&L, balance sheet, cash drawer, bank accounts, expenses and fiscal-year close.
Staff & HR
User roles and permissions per counter, shifts and attendance, salary, payouts, commissions and an employee self-service app (Advanced plan).
Tax & e-invoicing
GST / VAT with inclusive or exclusive prices, tax breakdown on the bill, Saudi ZATCA and UAE VAT e-invoicing with QR (Advanced plan).
AI that works for you
Ask your data a question in plain English, AI sales insights and stock alerts, AI-written WhatsApp and campaign messages, AI reports you can export (add-on).
The same business also opens on iPhone, Windows, macOS, Linux and the web — so the owner can watch the SUNMI counter from anywhere. See everything in MCPOS Cloud.
SUNMI for restaurants and cafés
A T2 or D3 PRO on the counter and a V2s PLUS in the waiter's hand is the most common restaurant setup we see. MCPOS gives you tables and floors, dine-in and take-away orders, KOT printing to the kitchen printer, split bills, service charge and tips, and a QR menu your customer scans at the table. The bill, the stock and the accounts all move together. See the restaurant POS system page for the full list.
Billing when the internet is down
SUNMI terminals are often used in markets, vans and stalls where the network comes and goes. MCPOS keeps a complete copy of your shop on the device: products, prices, customers, dues and today's bills. You can bill, print, take returns and close the day with the SIM removed. When the terminal reaches Wi-Fi or mobile data again, everything syncs to the cloud and to your other devices — no re-typing, no lost bills.
One business, many SUNMI machines
Two counters, a kitchen and the owner's phone can share one business. Each staff member gets their own login and their own permissions — a cashier can bill but not change prices, a supervisor can give discounts, the owner sees everything. Stock moves between branches and warehouses, and the day-end cash drawer is counted per till, per device.
SUNMI POS app — frequently asked questions
Does MCPOS work on the SUNMI V2 PRO?
Yes. Install MCPOS Cloud from Google Play on the V2 PRO, create your business and start billing. The built-in printer works as the paired Bluetooth printer InnerPrinter, and the scanner and camera work for barcodes.
How do I print a bill on a SUNMI terminal?
In MCPOS go to Settings, Printers, add a Bluetooth printer and choose InnerPrinter, which is the printer inside the SUNMI. Set 58 mm on handhelds like the V2 series and 80 mm on counter machines like the T2 or T3 PRO, then print a test receipt.
Is there a free POS app for SUNMI?
MCPOS Cloud is free to start — you can create a business and bill without paying. Paid plans start at 26 US dollars per user per year and add accounting, e-invoicing, HR, the online store and the restaurant features.
Can MCPOS print KOT to a kitchen printer from a SUNMI?
Yes. The SUNMI inner printer can print the customer bill while a separate Bluetooth, USB or network thermal printer in the kitchen prints the KOT. Both are set up in MCPOS Settings, Printers.
Will MCPOS work on a SUNMI without internet?
Yes. MCPOS bills fully offline on the device and syncs later. This is normal use for SUNMI handhelds in markets, vans and outdoor stalls.
Does MCPOS support the SUNMI T3 PRO and D3 MINI?
Yes. Both are Android desktop terminals and run MCPOS like any other Android device. The T3 PRO usually prints 80 mm receipts and the D3 MINI 58 mm or 80 mm depending on the model you bought.
