Free POS Software in Vietnam 2026: VietQR, MoMo, ZaloPay

In Vietnam, the tạp hóa (neighbourhood grocery) is the backbone of everyday retail — and the phone has become the cash drawer. Customers increasingly pay by scanning a VietQR code or tapping MoMo and ZaloPay instead of handing over notes, in Hồ Chí Minh City, Hà Nội, Đà Nẵng and the provinces alike. QR acceptance among merchants has reached around 85%, and digital wallets now take a third of the payment market — a shop that only takes cash is starting to lose sales.

So the right till must do four simple things: record each payment method cleanly (cash, VietQR, MoMo, ZaloPay kept separate), handle the đồng (VND, ₫), work offline when the signal drops, and cost nothing per month. That is exactly what a small Vietnamese shop needs — and rarely what traditional POS terminals offer, since most come bundled with hardware and a monthly subscription.

The smartest move in Vietnam is to lean on VietQR, the national QR standard run by NAPAS (the National Payment Corporation of Vietnam) over its NAPAS 247 instant-transfer rails. Its big advantage: it is interoperable — a customer paying from any of 40+ banking apps, or from MoMo, ZaloPay or ShopeePay, scans the same VietQR code. One sticker handles every bank and wallet, instead of a separate QR per app.

For a business, you can get a VietQR code tied to your bank account, and add merchant accounts on MoMo and ZaloPay if you want their wallet flows too. Then the critical step is recording the sale at the till:

- The customer scans your VietQR code (or your MoMo/ZaloPay merchant QR). - You wait for the payment confirmation on your side — the bank/wallet notification, not the customer's screenshot, which is easily faked. - You log the sale with the right method, so your end-of-day report clearly splits cash, VietQR, MoMo and ZaloPay.

Without that discipline, reconciling your bank and wallet statements against the drawer is guesswork. A till that creates one payment method per channel turns it into a clean daily report.

digabloPos is free for life on its core POS:

- Records VietQR, MoMo, ZaloPay and card as separate payment methods, so your daily report splits cash from each wallet — no more guessing what landed where. - Native đồng (VND). Prices, receipts and reports in đồng, with no decimals and thousands separators the way your customers read them (e.g. 25.000 ₫). - Works offline. Sell, track stock and print receipts with no signal; everything syncs when the connection returns. Built for patchy data and busy market hours. - No monthly fee. Unlimited sales and products, two staff, receipts, reports — free. Optional modules only if you grow. - Any Android phone. No expensive terminal; an optional Bluetooth thermal printer for printed receipts. - Customer credit (bán ghi nợ / mua chịu). Track credit sales and each regular's outstanding balance — the notebook tab, but clean and tallied.

Vietnam has a strong local POS market — but most of the well-known names are paid monthly subscriptions. Here is where they sit:

- digabloPos — free for life, offline-first, đồng, records VietQR/MoMo/ZaloPay, on any Android. Best for zero recurring cost and no dependence on the signal. - KiotViet — the dominant local POS for shops, cafés and street vendors; affordable but a paid monthly plan per store (and per branch as you add them). - Sapo — multichannel POS popular with sellers who also list on Shopee and Lazada; subscription-based. - iPOS.vn / MISA CukCuk / POS365 — capable F&B systems (table management, kitchen tickets) aimed at restaurants and chains; paid plans, premium tiers around 370.000 ₫/store/month. - Loyverse — a genuinely free mobile POS (free core, paid add-ons), a solid free alternative too.

If your checklist is "no monthly fee + offline + đồng + VietQR/MoMo/ZaloPay," digabloPos and Loyverse are the strongest free starting points; the local subscription suites complement them when you need deep F&B or marketplace features.

The same free core adapts to most Vietnamese trades:

- Tạp hóa (grocery / convenience). Barcodes, real-time stock, credit tracking for regulars, and clean VietQR/MoMo reconciliation. - Quán ăn and quán cà phê (eatery and coffee shop). Quick item buttons, send orders to the kitchen, and VietQR at the counter or table. - Nhà thuốc (pharmacy). Batch and expiry tracking, scan the box to identify the product automatically. - Chợ vendor (market stall). Everything on the phone, offline, no hardware: you sell even with no signal and it all syncs later.

You start with the free till and only switch on a module (kitchen, batches, multi-store…) the day you actually need it.

An honest, important note for Vietnam. A free till covers your day-to-day operations — recording sales, tracking stock, reconciling wallets and producing a clean sales report. That is the operational backbone most small shops need.

But the electronic invoice (hóa đơn điện tử) is a separate, regulated layer run by the General Department of Taxation (Tổng cục Thuế / GDT). Under Decree 70/2025/ND-CP (in force since 1 June 2025), business households and individuals with annual revenue of VND 1 billion or more, plus consumer-facing sectors (restaurants, supermarkets, hotels, retail and more), must issue e-invoices generated from cash registers (máy tính tiền) connected to the GDT, in the official signed XML format, transmitted to the tax authority. On VAT (GTGT): the standard rate is 10%, with a temporary 8% rate applying to most goods and services through 31 December 2026 (Resolution 204/2025/QH15).

So treat digabloPos as your store-management and reporting system — it is not a GDT-certified hóa-đơn-điện-tử issuer. The legal e-invoice must go through an authorized e-invoice provider / the GDT system; keep that running alongside your till. The clean sales base digabloPos gives you makes that reporting far easier — and always confirm the requirements for your revenue level with the GDT.

1. Download digabloPos on your Android phone (or open it in a browser). 2. Add your products (or import a list) and set the Vietnamese đồng (VND). 3. Add VietQR, MoMo and ZaloPay as payment methods. 4. Make your first sale — pair a Bluetooth printer if you want receipts.

No contract, no monthly fee, and it keeps selling when the signal drops.
