uniCenta oPOS

Overview

uniCenta oPOS is open-source point-of-sale software for retail and hospitality, with versions for desktop use and a browser-based option. It suits businesses that need more than checkout, particularly stock control, restaurant workflows or support for multiple locations. Its broad feature set and free download are compelling, but the subscription tiers and reliance on third-party hardware deserve a close look before adoption.

Founded in 2010 and headquartered in London, its maker describes the software as commercial-grade. Version 5.0 is free to download under the GNU GPL3 license. Retail, hospitality, mixed-use venues and specialist businesses are among its intended settings, so it is aimed at operators whose sales floor or service model needs dedicated POS workflows.

Key features

Checkout supports barcode scanning, customizable receipts, multiple payment methods and terminals, and secure user logon. Restaurant and retail modes, table management, split receipts, refunds and discounts let it address both counter sales and table service. That breadth is useful for mixed-use venues, though businesses should weigh it against the setup they need rather than assume every workflow is equally suited to every operation.

Stock management includes multiple warehouses and stores, while sales reporting, employee permissions and multi-location support extend the system beyond a single till. These capabilities make it a stronger fit for operators coordinating inventory and staff across sites than for a business seeking only a lightweight checkout tool.

WooCommerce can connect to retrieve customers, orders and products, including for table ordering and click-and-collect use. Customer, order and product APIs support synchronization and connections to other applications. Integrated card payments are advertised for the UK, EU and USA as secure EMV/PCI payments. Hardware support is third-party, so operators should confirm their equipment requirements before choosing it.

Pricing

The model is freemium: version 5.0 is free to download, and paid subscriptions start at £6/mo (annual). Paid plans chiefly add update and support provisions, API access or hosted operation; they do not change the core case for choosing the free software. The downloadable plans are a better match for businesses prepared to manage their own installation, while HOSTED is for those who value managed hosting and backups.

• BASE: £6 per month charged yearly (£72). It includes downloads and source code, update notifications, web reporting, standard forum support, user and developer guides, and API access. It is the lower-cost subscription for operators who want the software and basic support resources; API access is not unlimited.
• PLUS: £12 per month charged yearly (£144). It adds priority forum support, limited developer support and unlimited API access, alongside downloads, update notifications, reporting, and guides. Choose it when integrations or faster forum assistance matter; it still leaves hosting to the subscriber.
• HOSTED: £15 per month charged yearly (£180). It includes everything on Plus, cloud hosting, a custom URL with HTTPS, daily backups, email support, a built-in web firewall and automatic upgrades. It runs on iPad, Android tablets and most browsers, making it the clearest fit for businesses that want hosted access without setting up hosting themselves.

All three prices are billed yearly, so the monthly figure is not a month-to-month commitment. The software continues working after a subscription expires, though the subscription's services are the reason to pay. Remote Order Display is in beta and available to Plus subscribers.

Platforms

Installers are listed for Windows, Linux and Apple Mac OS X. The software can also run in a browser on Android or iOS devices; the hosted tier specifically supports iPad, Android tablets and most browsers. This gives businesses a choice between local desktop installation and browser access, with cloud hosting confined to HOSTED. The range is useful, but third-party hardware support means device compatibility remains an important part of the decision.

Who it's for

uniCenta oPOS is best suited to retail and hospitality operators that need inventory tools, staff permissions, reporting and multi-store or multi-warehouse workflows, especially those willing to work with open-source software. HOSTED is more appropriate for teams that want cloud access, backups and automatic upgrades bundled together. A business looking for a simple, fully managed till with confirmed first-party hardware compatibility should consider other options.

Pros and cons

• Pros: The free GNU GPL3 version gives businesses an open-source way to access retail and hospitality POS workflows without a paid subscription.
• Pros: Table service, split receipts, refunds, discounts, and stock across warehouses and stores serve varied operating models.
• Pros: APIs and WooCommerce connectivity support syncing products, customers and orders with other systems.
• Cons: Hardware support is third-party, so businesses must check that their equipment needs can be met.
• Cons: BASE, PLUS and HOSTED are billed yearly; buyers wanting hosted operation must pay £180 per year for HOSTED.
• Cons: Community forums are free but unsupported; subscribers receive online support and a knowledge base, with email support included on HOSTED.

Alternatives

RetailPOS is worth considering for a free, self-hosted option with no monthly fees, particularly if Apache 2.0 licensing is preferable.

Loyverse is another freemium POS option; its paid Unlimited sales history plan costs $5 a month per store, while its free POS plan has 31 days of sales history.

Heartland Retail is an alternative for readers considering a freemium retail POS with a paid starting price of $89 a month.

Posnic POS may suit readers comparing another open-source option: its desktop application source is published under AGPL-3.0-only.

Erply is a paid alternative with a listed Growth Plan at $1,000 a month.

NCR Voyix POS, Oracle Retail Xstore Point-of-Service and Cegid Retail are additional paid alternatives with custom pricing.

Verdict

Choose uniCenta oPOS if your retail or hospitality operation needs an open-source POS with stock, service and multi-location capabilities, and you can take responsibility for hardware fit and deployment. The free download is its strongest draw; look elsewhere if you need a simpler commitment, month-to-month pricing, or confirmed first-party hardware support.
