Odoo Point of Sale

Odoo is a Belgian software company headquartered in Grand Rosiere and founded by Fabien Pinckaers. It builds a suite of open source business apps covering CRM, e-commerce, accounting, inventory and point of sale, reports more than 28 million users and has Asian offices in India, Hong Kong and Jakarta.

Odoo Point of Sale runs on tablets, laptops, desktops and industrial machines and works online or offline, syncing payments when the connection returns. Because it shares one database with Odoo Inventory, Accounting, eCommerce and loyalty tools, stock, promotions, gift cards and invoices stay consistent across stores and the webshop. Separate shop and restaurant flavours add self-ordering kiosks, click and collect, preparation displays and IoT links to scanners, scales and payment terminals. Twice-yearly releases add country localizations, including Vietnamese e-invoicing.

• Flexible checkout: Supports multiple cashiers with badge or PIN login and invoices by email or QR code.
• Offline mode: Keeps selling without internet and syncs payments later.
• Loyalty and promotions: Manages points, gift cards, coupons and eWallet refunds.
• Self-ordering: Lets customers order and pay on a kiosk or smartphone.
• Click and collect: Takes online orders for store pickup with preparation displays.
• Integrated back office: Shares data with Odoo Inventory, Accounting and eCommerce.

A Vietnamese bookstore or homeware chain can run store checkout, stock and accounting in one Odoo database and issue e-invoices via SInvoice. A bakery chain can add self-ordering kiosks and click and collect for online orders. A distributor with showrooms can sell to both walk-in and B2B customers from the same POS.

The first Odoo app is free with unlimited users, hosting and support, so a single store can start POS without licence cost. Sharing one database with inventory, accounting and e-commerce removes double entry between store and back office. Offline mode keeps stores selling during outages. Localization updates, such as POS e-invoices via SInvoice in Vietnam, help chains stay compliant as tax rules change.

Small and mid-sized retailers in Southeast Asia want POS that is part of a wider ERP rather than a standalone register, so store sales flow directly into stock and accounting. In Vietnam, the shift to e-invoices generated from cash registers since 2025 increases demand for POS with built-in local e-invoice connectors.

Odoo S.A. is headquartered in Grand Rosiere, Belgium, led by founder and CEO Fabien Pinckaers. Reports 28 million+ users and 8,000+ employees, with Asian offices in Gujarat (India), Hong Kong and Jakarta. Code is open source on GitHub.
