What We Recommend uniCenta For
uniCenta made it to our best open source POS software list, scoring a 3.54 out of 5 based on our criteria. It is the only platform we have reviewed among the many open source apps that support multiple languages, currencies, and locations. It also has excellent customer management features—loyalty and VIP programs, customer information, transaction history, credit limits, and more. However, we found no way to perform program tipping or payroll processing in its backend or see a mention of them in the online resources or demos.
In short, uniCenta is best for:
- Global businesses: If you operate internationally, you will find uniCenta’s multi-currency and multilanguage features an advantage. It also can support multiple locations—terminals, stores, and warehouses—so you can have a single system throughout.
- Businesses that give out loyalty and VIP rewards programs: uniCenta is one of the few open source POS platforms with built-in CRM features. You can assign unique barcodes, discounts, and credit limits to customers and view their transaction histories.
When uniCenta Would Not Be a Good Fit
- Stores wanting employee management tools: uniCenta lacks specific tools for employees, such as tipping management and payroll processing. While it does have time tracking, it doesn’t provide time scheduling. If you need time tracking and payroll management, try Square.
- Stores that need a mobile app: While uniCenta works with mobile devices and tablets, you need a remote desktop protocol (RDP) client to connect to; it might be a bit of a workaround for those who are not tech-savvy. Consider any of our top-recommended mobile POS apps for Android or iOS such as Square and Lightspeed. If you are looking specifically for those that work with iPads, then check out our top picks for the best iPad POS systems.
- Convenience and liquor stores: You’ll want specialized features to handle things like age verification and bottle tracking. See our recommendations for the best convenience store POS systems and best POS systems for liquor stores.
If you are unsure of what to look for, then read our article on what is a POS system and how to determine which is best for you. We also have a guide to the best POS systems for small businesses to help you find a solution that matches your needs. If you are on a budget but do not want the complexities of an open-source product, several free commercial POS systems are available.

uniCenta Features
While setting up an open source POS is more complicated (at first) than using cloud-based software, uniCenta provides an installation guide and video library to walk you through the process. You just need to download uniCenta’s installer, MySQL server, and the latest version of Java. After installation, you can configure your POS. An overview video is available on the provider’s website. We have summarized the steps below:
- Go to general settings
- Set up local settings: currency, language, and location (dates and number formats)
- Specify payment methods (card reader and gateway)
- Connect peripherals (printers, scanners, and more)
- Set advanced features such as keyboard shortcuts, automation, etc. (optional)
- Set up ticketing system (number of orders and receipts)
- Input company details and ticket message
- Create and set up a database, then click Connect.
Once connected, you can start using your uniCenta POS program.

uniCenta offers basic restaurant features that can help you process orders from the kitchen or store. However, we did not find tip management features, which are important to many restaurant and hospitality businesses. If you need restaurant-specific features, choosing from our top-recommended restaurant POS systems might be a better choice.
uniCenta Inventory
- Categories
- Multistore, multiwarehouse
- Bundles
- Stock management
- Supplier assignments
- Stock transfer
Granular inventory such as variants, bundles, and categories can be configured in uniCenta. Since it can also support multiple locations, you can track stock inventory across different places, like stores and warehouses. While you can set minimum and maximum stock levels per product, it does not seem to offer low-stock alerts. We also did not see purchase order and COGS reporting features—essential inventory management features if you want to monitor sales and profit in real time. If you need more advanced inventory management features in a POS system, our best POS inventory systems guide can help you.
uniCenta Customer Management
- Credit limit
- Customer information
- Transaction history
- VIP
uniCenta provides strong customer management features that let you engage with customers better. Along with customer information, you can upload a photo in their profile to easily identify them. Their transaction history is also attached to their profile so that you can identify their spending habits and product preferences. You can also assign a VIP status to select customers—and uniCenta will trigger an in-sale VIP pop-up notice when a customer is assigned to a ticket.
We did not see management or employee features such as payroll processing. While it has employee reports, it only covers performance evaluations and security information.
uniCenta Ease of Use
- Self-service onboarding
- FAQ section
- Community forum
- Video library
- Developer section
uniCenta provides a list of compatibility requirements for hardware and minimum operating system standards before you install the program. While it doesn’t have a knowledge base available to the public, uniCenta has a library of videos you can refer to for installation and setup. It also refers users to its community forum and developer section.
For its free users, uniCenta does not provide customer support. If you need one-on-one help, then you need to sign up for an annual support membership; this enables you to speak with its experts for guidance and troubleshooting.

What Users Think About uniCenta
At the time of publication, uniCenta has very few and outdated reviews on popular user review sites. However, other critics have reviewed its POS application. PAT RESEARCH gave uniCenta a 9.5 editor rating and a 6.5 aggregated user score based on 13 ratings. Editors rated its performance the highest—a 9.6 score—while users rated its ease of use a 5.0.

Bottom Line
uniCenta is one of the most popular open source platforms we have reviewed, and rightly so. Its built-in features, especially its CRM and multilingual support, are definitely something we don’t usually see offered (and if they are, they are premium add-ons). We don’t recommend uniCenta for those who are not tech-savvy, as it doesn’t provide customer support unless you sign up for a paid subscription. However, if you want to customize your POS platform and have a tech developer to do it to support your business operations—mainly if you operate internationally—uniCenta is an excellent option to consider.
