What We Recommend Odoo For
Odoo’s POS app (which this review focuses on) is our top-recommended open-source POS system, earning a 3.91 out of 5 score based on our evaluation criteria. Its biggest advantage is having built-in solutions for inventory and invoicing modules, allowing for an efficient workflow across sales tracking, bookkeeping, inventory management, warehouse locations, and product monitoring.
In short, Odoo is best for:
- Small businesses needing a customizable all-in-one business software: Odoo’s well-reviewed POS comes packaged with its excellent free inventory management, material planning, sales forecasting, and CRM solutions to name a few.
- Warehouse management and dropshipping businesses: Odoo’s automatic stock replenishment and inventory forecasting are advantages for dropshipping businesses with high-volume orders. Tracing stock is also easier for suppliers—given its double-entry inventory system.
When Odoo Would Not Be a Good Fit
- Regulated industries: Odoo doesn’t have features to manage unique industry regulations, such as those for liquor and tobacco. Check out our recommended vape shop, liquor store, and convenience store POS systems for a better fit.
- Large retail stores needing multichannel sales tools, CRM features, and thorough business analytics: Odoo’s reporting tools are basic and may not be enough for multichannel retailers or businesses with extensive inventories.
|Free POS, Invoice, and Inventory||No available third-party integrations|
|Modules for stores, restaurants||Paid Odoo integrations—these can add up fast when adding modules|
|Inventory forecasting||Ecommerce excluded|
|Stock replenishment automation||Implementation and customization are unintuitive|
|Double-entry inventory system|
Odoo’s POS app is free to use as a package with Invoicing and Inventory apps. However, there is a fee to integrate it with other Odoo apps, and monthly fees usually start at $42.50 per user. When you sign up, you get unlimited users, locations, products, and transactions.
Most apps that require payments are listed on Odoo’s pricing page. Some are also offered for free (such as Survey, Discuss, Notes, Chat, and Employees). However, note that other apps are already bundled within others (like Blog, Forum, Live Chat, and Slides are within the Website App).
Signing up for Odoo gives you access to its platform—including hosting, daily backups, email integration, 24/7 monitoring and security, and a control center.
Odoo POS Payments and Hardware
To accept credit card payments in Odoo POS with an integrated card reader, you have to use MercuryPay and sign up for its merchant account. It operates only with US and Canadian banks, making this set up exclusive for North American businesses.
However, Odoo provides a turnaround solution: businesses work with a standalone card reader, copy the transaction total from the Odoo POS screen into the card reader, then record the transaction in Odoo POS. An IoT box (an added charge, which will be discussed shortly) can also provide integration with third-party providers and payment terminals.
In our evaluation of Odoo for the best open-source POS software, the lack of direct payment processing integrations prevented it from getting a perfect overall score, as it really limits options for integrated payment processing.
For hardware equipment, these can be purchased separately. However, the system is compatible with most commercial POS systems, tablets, and computers.
An IoT Box ($20.00/month/box) is required for some devices, such as weighing scales and a customer display. It is a cross-platform hardware solution that lets you use the same USB POS peripherals (input/output) on every device.
- Barcode Scanners: Odoo POS will work with most USB Barcode Scanners, connected directly to your computer. It recommends the Honeywell product line.
- Weighing Scales: The IoT Box can provide support for the Mettler Toledo Ariva product family and Adam Equipment scales product family (AZExtra Series).
- Cash Registers: Odoo POS can operate any EPSON compatible cash register. It recommends the Metapace K-2.
- Receipt Printers: Odoo POS can print on any web browser-compatible printer (inkjet, laser, and thermal).
- Payment Terminal:
- No IoT Box Required: Adyen (supported countries) – swipe, EMV, contactless; SIX (Europe) with a Yomani terminal
- IoT Box Required: Worldpay / FIS (USA, Canada) – swipe-only

While setting up an open-source POS such as Odoo can be more challenging than downloading a cloud-based POS app, Odoo provides a detailed step-by-step guide with illustrations on its website. There are plenty of how-to videos to help you, but as an overview, here are the steps:
- Connect peripheral devices
- Power the POSBox
- Set up the Point of Sale
- Configure the Wi-Fi
- Install POS app
- Add products
- Configure payment method and points of sales
Once you have set up Odoo, you can simulate a new order by clicking on New Session.

Odoo makes handling sales, stock management, and accounting easy with its POS/Inventory/Accounting package. Its built-in double-inventory system gives it an advantage over other open-source POS platforms because it lets you track every stock move from purchase, warehouse bin, to a sales order. With such a system, your items are moved along the pipeline rather than removed from the system, allowing for its easy traceability.
Take a look at the rest of its features below so that you can decide if it’s a perfect fit for your business.

Since Odoo is developed on an open-source platform, expect a more extensive setup that might need the help of a developer if you are not tech-savvy. However, its knowledge base and community forum are comprehensive if you know how to navigate your way through the set up guide. It doesn’t provide phone support, and the user reviews I have read online lament its poor customer service.

What Users Think About Odoo
Most Odoo reviews I read online are positive, with a majority of users saying that Odoo is a complete system for their business—ecommerce, accounting, POS, HR, and ERP. They particularly like Odoo’s inventory and accounting features, remarking that these provide the most value.
However, Odoo’s open-source platform is a double-edged sword. While there are some that like the flexibility it gives, many still left feedback that it is not easy to set up and that the user interface is unintuitive. Many also complained that its customer support team takes a long time to get back to their requests.
At the time of publication, Odoo reviews earned the following scores on popular user review sites:
When reading through user reviews, I noticed some of these trends:
Users Don’t Like
Strong inventory, warehouse, and ecommerce features
Customer support isn’t as helpful and takes a while to respond
Open source gives more flexibility for customization
Difficult to set up for the not-so-tech-savvy
Built-in apps/modules cover almost everything you need or want to do
User interface is not intuitive
Odoo’s free POS provides all the basic features most small businesses need for running a retail shop or restaurant. If you are in need of a specific feature such as ecommerce, it is most likely available as a paid add-on. Odoo’s add-on apps can be pricey when stacked up and Odoo has limited payment processing integrations; however, there is definitely enough of everything for most businesses to start with (and eventually scale).
