Odoo’s well-reviewed POS comes with a free inventory management module, along with other modules for sales forecasting and CRM solutions, to name a few. Using Odoo for your small businesses is a good idea if you value flexibility and the ability to customize—however, this does require some technical know-how.
The system’s automatic stock replenishment and inventory forecasting are advantages for dropshipping businesses with high-volume orders or businesses that need solid warehouse management. Given the system’s double-entry inventory system, tracing stock is also easier for suppliers.
On the other hand, businesses that deal in regulated products will want to consider a different POS, as Odoo doesn’t have features to manage unique industry regulations, such as those for liquor and tobacco. These businesses can check out our recommended vape shop, liquor store, and convenience store POS systems for a better fit.
Odoo’s reporting tools are also fairly basic and may not be enough for multichannel retailers or businesses with extensive inventories. Businesses with these needs may benefit more from POS systems like Shopify POS or Lightspeed Retail.
Odoo Pricing
5.00 / 5
Odoo earned perfect scores for pricing. It is free to use as a starter package with Invoicing and Inventory apps (though there is a monthly fee to integrate it with other Odoo apps, usually starting at $43.50 per user). Most apps that require payments are listed on Odoo’s pricing page.
When you sign up, you get unlimited users, locations, products, and transactions. Right from the start, you’ll also have lots of embedded payment providers available, including Alipay, PayPal, and Authorize.net. 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.
Payments & Hardware
To accept credit card payments in Odoo with an integrated card reader, there are several payment providers you can work with.
For those that have payment providers not on Odoo’s list, Odoo provides a workaround solution: Businesses work with a standalone card reader, copy the transaction total from the Odoo screen into the card reader, and then record the transaction in Odoo. An IoT box (an added charge, which will be discussed shortly) can also provide integration with third-party providers and payment terminals.
If you want more hardware and functionality beyond Odoo’s mobile POS app, you can purchase additional hardware separately. However, the system is compatible with most commercial POS systems, tablets, and computers.
An IoT Box ($20.00/month/box) is a cross-platform hardware solution that lets you use the same USB POS peripherals (input/output) on every device. It is required for some devices, such as weighing scales, customer displays, and payment terminals. It comes fully integrated with all Odoo apps.
Other hardware options include:
- Barcode Scanners: Odoo POS will work with most USB barcode scanners, connected directly to your computer. The Honeywell product line is recommended.
- Weighing Scales: The IoT Box can provide support for the Mettler Toledo Ariva product family and Adam Equipment scales product family (AZExtra Series). The Box allows Odoo POS to integrate with electronic weighing scales.
- Cash Registers: Odoo POS can operate any EPSON-compatible cash register. Odoo recommends the Metapace K-2 model.
- 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; Stripe payment terminals (supported countries and payment terminals)
- IoT Box Required: Ingenico (Belgium, Luxembourg) with a Lane/5000, Desk/5000, Move/5000 terminals; Worldline (Europe) with a Yomani terminal; Vantiv / FIS (USA, Canada) – swipe-only.
Odoo Checkout Features
4.13 / 5
Odoo’s checkout features earned above-average scores. The POS includes essential register and checkout features for your retail business needs. It can handle tipping management and cash tracking. Loyalty features, gift cards, and online ordering functions are available—but if you want to access these, you will need to either pay added fees to get the necessary modules or make manual changes in the POS settings menu.
Other checkout features include:
- Checkout interface, which allows serving multiple customers at the same time
- Barcode scanning to apply discounts, identify loyalty cards, and scan item prices
- Cloud-based with offline mode (for open tickets)
- Split tenders, currency rounding, and tipping
- Customized receipts
- Electronic scale integration is available
- Compatible with iPad and Android tablets (mobile POS)
- Parallel orders (put orders aside and process multiple orders at the same time)
- Built-in search features
Odoo Management Features
3.63 / 5
Odoo makes handling sales, stock management, and accounting easy with its POS/Inventory/Accounting package. Its built-in double-entry inventory system gives it an advantage over other open source POS platforms because it lets you track every stock move from purchase to warehouse bin to sales order. With such a system, your items are moved along the pipeline rather than removed from the system, allowing for easy traceability and fewer errors.
Overall, the Odoo POS, inventory, and invoicing app bundle is a great advantage for businesses because it allows for an efficient workflow across sales tracking, bookkeeping, inventory management, warehouse locations, and product monitoring. Odoo could have earned additional points in this category if more of these functions were available in the base POS, rather than requiring extra modules.
For more management tools beyond the basic package, note that you may need to pay extra fees. Odoo’s management tools for different functions include:
Store Management
- Monitor cash register adjustments at the end of day
- Cashier account assignment with badges or pin codes
- Order history by customer, product, cashier, or date
- Franchise management
Restaurant
- Split bills, kitchen order notes, send orders to bar and kitchen printers
- Floor plans, table mapping, guest tracking for table availability
- Delayed orders (take orders for different courses at once and send them to the kitchen printer at separate times)
Inventory Management
Odoo is our top overall choice for free inventory management software—and for good reason.
Right off the bat, with the free version of the app, you’ll get an inventory management module with unlimited products and locations, making it a great feature regardless of your business’ inventory size. Built-in expiration date tracking minimizes your wasted stock and can help prevent over-ordering. Inventory forecasting and automatic purchase orders from suppliers are also at your fingertips, ensuring that you can optimize your inventory from all angles and never miss a beat—whether for maintaining adequate stock levels or planning for the growth of your business.
Other handy features that make Odoo great at inventory management include:
- Double-entry, immediate updates across all stores, and programmable reorder points
- Dropshipping, multiple warehouses, and inventory reports
- Refund claims, schedule delivery, warranty tracking
Product Management
- Categories, search, measuring units, product variants
- Support for large product counts—over 100,000 products
Accounting
- Invoicing—quotes-to-invoices and sales analysis reports
- Payments are directly integrated into Odoo Accounting for efficient bookkeeping
CRM
While Odoo does include a CRM feature (it made our guide to the best open source CRM software), you will need to obtain the appropriate module to unlock specific CRM functions. This module will be free to use for about two weeks, after which you will need to pay for a subscription.
Odoo’s CRM feature lets you create a detailed plan for generating leads. You can set the number of companies and contacts that you intend to reach out to, choose from an extensive list of industries, and specify a sales contact from your own business. This level of detail ensures that you have a crystal-clear picture of the businesses you’d like to connect with, along with maintaining accountability from your sales team.
If you need more help maximizing the CRM feature, you can read extensive documentation for this on Odoo’s site.
Odoo Ease of Use
4.00 / 5
Odoo scored well for ease of use, with highlights including its cloud-based nature and offline mode. A small deduction was given for its somewhat limited customer service hours.
Since Odoo is developed on an open source platform, expect a more extensive setup that might require a developer if you are not tech-savvy. However, if you know how to navigate your way through the tutorials and documentation, Odoo’s knowledge base and community forum are comprehensive and regularly updated. It provides email support and live chat, but no phone support, and some user reviews online lament its poor customer service.
Odoo Setup & Installation
While setting up an open source POS such as Odoo can be more challenging than downloading a pre-built POS app, Odoo provides a detailed step-by-step guide on its website. There are also plenty of how-to videos available to help you.
To summarize the process of software installation:
- Install POS app
- Add products and make them available
- Configure payment methods
- Open and close sessions/transactions as needed
Odoo Expert Score
4.00 / 5
We considered any unique or standout features, the overall value that Odoo provides, user reviews for the POS, and feedback based on our experience testing the system.
Odoo is the most popular of all the open source POS systems we have evaluated, and its popularity is strengthened by the majority of user feedback. Having tested dozens of POS systems (open source and standalone software), we find Odoo’s feature tool set enough to meet a small business’ POS needs.
Odoo’s open source nature is a double-edged sword, depending on your business needs as well as your level of technical expertise. If you operate a small business and don’t need much beyond the basics, then you will probably appreciate Odoo’s simple yet functional starter package. It contains essential functions such as invoicing and inventory, and can be set up just the way you want. However, if you’re running a quickly-growing business and anticipate a need for more complex features like product lifecycle management, ecommerce, and subscriptions— then you might find the costs piling up as you add more and more of the required apps and modules to the basic POS. Having to continuously adjust settings as you accumulate modules might also become frustrating for users who aren’t very tech-savvy.
What Users Say in Odoo Reviews
Most Odoo reviews we have 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, while there are some that like the open-source flexibility Odoo gives, many still left feedback that it is not easy to set up and the user interface is unintuitive. Many also complained that its customer support team takes a long time to respond to requests.
At the time of publication, Odoo reviews earned the following scores on popular user review sites:
- Capterra: 4.1 out of 5 based on over 600 reviews
- G2: 4.3 out of 5 based on more than 10 reviews
Here are Odoo users’ commonly cited likes and dislikes about the software:
| Users Like | Users Don’t Like |
|---|---|
| Strong inventory, warehouse, and ecommerce features | Customer support somewhat limited and takes a while to respond |
| Open source nature gives more flexibility for customization | Can be difficult to set up for the not-so-tech-savvy |
| Add-on apps/modules cover almost everything you need or want to do | Coordination between different apps/modules is sometimes lacking |
| Offline mode is available and reliable | Adding functions via apps/modules can quickly become costly |
Methodology—How We Evaluated Odoo
Odoo Frequently Asked Questions (FAQs)
Is Odoo totally free?
Odoo’s POS app is free to use as a starter package; you’ll have immediate access to its invoicing and inventory functions. But if you need additional business features like a CRM system or time sheets, you will need to integrate with other Odoo apps or modules. These come with integration fees, usually starting at $43.50 per user.
What are the disadvantages of Odoo?
Odoo works exclusively with apps in its ecosystem. Therefore, you are limited to working with its other apps if you need more business features. Most of its apps also come with separate fees, which add to your business costs.
What are the differences between Odoo POS on a computer versus the mobile app?
Both perform essentially the same functions and can be linked so actions you perform in one will be reflected in the other. Note that the interface of the computer version looks quite different from the mobile version, which can lead to some confusion if you are constantly switching between the two.
Bottom Line
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; however, there is definitely enough of everything for most businesses to start with (and eventually scale).
