Best Supermarket Billing Software

Square for Retail is Square's point of sale configured specifically for retail businesses, where the central problem is not taking payment but knowing what is on the shelves. Square puts it as spending less time tracking stock and more time selling, and the product's distinguishing work is inventory management rather than the checkout itself.

Stock updates in real time across every location and sales channel, so a business does not oversell an item or discover a shortage after the fact. Every sale, restock and adjustment appears in one place, which makes trends visible early enough to act on rather than only explaining a stockout afterwards. Inventory can be organised, updated and received across multiple items at once, which matters for any shop receiving deliveries in bulk.

Supplier workflow is handled inside the product. Purchase orders and vendor profiles can be created so ordering, tracking and receiving inventory happen in the same system that records the sales, rather than in a spreadsheet alongside it. Barcode labels can be created and printed using supported label printers, dimensions and templates.

A particularly practical touch is the stocktake tool, which uses an iPhone or iPad camera to update, review and confirm inventory counts, turning a device the shop already owns into the counting hardware. Pricing starts at $0, with Square describing value-packed plans, no hidden fees and no locked-in contracts, cancellable or switchable at any time. Businesses processing over $250,000 per year are directed to Square Pro for custom pricing.

Epos Now supplies point of sale systems to more than 80,000 locations globally, across retail and hospitality. The proposition combines hardware and software in a single bundle: a POS terminal, card machine and printer, described as everything needed to trade, currently advertised from £299 against a list price of £849.

The retail configuration focuses on streamlining operations, automating inventory and supporting marketing. The hospitality configuration syncs front and back of house, integrates with delivery apps and handles fast payment acceptance, which reflects how different those two businesses actually are at the counter. A separate AI-driven multi-site option serves businesses running several POS systems or opening additional locations.

Reporting is real-time and covers staff, customers, sales, margin and stock, accessible from any device so an owner can check the business without being on site. Epos Now emphasises hardware performance in blunt commercial terms, noting that a faster processor means a faster checkout, which serves more customers and avoids losing a sale to a queue.

The system can be used standalone or connected to hundreds of applications including payment systems and accounting software, so it fits alongside tools a business already runs. Buyers should read the bundle terms carefully: the advertised hardware price requires a 12-month payments, care and support subscription starting at £54 per month, and Epos Now states the monthly rate offered may differ from the representative figure. A comparison tool helps match systems and customise a bundle before purchase.

CATAPULT is ECRS's retail POS platform, and its defining technical claim is architectural: the same transactional logic runs across the entire enterprise. ECRS describes this as going beyond unified commerce, and the practical consequence is that checkout lanes, self-checkouts, deli scales, pharmacy, fuel and eCommerce all work as one system rather than as separate systems reconciled afterwards.

For a supermarket that distinction is substantial. A store running a deli counter, a pharmacy and fuel alongside general grocery usually operates several point of sale systems with different pricing engines and separate promotion logic, which is why a promotion can apply correctly at one touchpoint and not another. Sharing one transactional core removes that class of discrepancy rather than reporting on it.

The platform unifies retail operations in real time, eliminating silos and delivering what ECRS calls friction-free automation across every touchpoint, with practical AI and intuitive tools intended to help staff work more effectively and produce a smoother shopper experience. Functional coverage spans real-time inventory, supply chain and category management through to dynamic promotions.

CATAPULT is presented as an end-to-end system that automates critical areas of the business and consolidates essential data into a single integrated system, giving 360-degree visibility across the enterprise. Where native functionality does not reach, built-in point of sale solutions and API integrations unify data from other POS systems, so a retailer mid-migration is not forced to switch everything at once. Pricing is not published; ECRS handles enquiries through a request process.

RetailEdge has supplied point of sale software to retailers since 1989, positioning on being both affordable and powerful. Its longevity shapes what it is: an on-premise system for specialty retailers, explicitly including businesses where cloud-based systems are not an option, such as hospital gift shops and some campus and museum locations.

The product's real distinction is depth by retail vertical rather than a general feature list. Fashion clothing stores get three-dimensional size and colour matrices for managing items, sophisticated discount rules for moving inventory ahead of a new season, and reporting that shows what is selling and what is not. Beer, wine and liquor stores get case breaks, batch billing, age verification and club membership. Bakeries and quick-serve businesses get fast selling to keep queues moving, loyalty and gift card programmes, and mobile tablet POS for deliveries. Gift shops get inventory organisation suited to a diverse and constantly changing product mix.

That vertical specificity is the argument against a general-purpose POS: features like case breaks or a size and colour matrix are either present or they are not, and working around their absence is where retailers lose time daily.

Pricing is transparent and unusually modest. Maintenance runs in three tiers: Bronze is free, Silver is $5 per workstation per month, and Gold is $45 per location per month, with technical support and training attached to the paid levels. A free demo is downloadable before purchase, which suits an on-premise product where evaluation means installing it.
