POS. Upgraded.

A POS system is the combination of hardware and software that businesses use to complete transactions, manage sales, and track payments. It includes features such as order processing, payment handling, and analytics, helping businesses streamline their sales operations and customer interactions. Today, POS systems encompass a variety of functions, including processing orders, taking payments, providing sales analytics, generating receipts, and more.

Whether you’re running a small market stall or a multi-venue operation, your point-of-sale will be the hub of your business that keeps everything running smoothly. Ultimately, it speeds up transactions — reducing queues and improving the customer experience — and tracks inventory and sales in real-time, giving you valuable insights into what’s selling and where so you can optimise stock levels and maximise profits.

POS systems come in various forms, and choosing the right one will depend on your business needs. Consider what hardware you’ll require — like a card machine, receipt printer, or barcode scanner — and the software features specific to your industry or business size, such as loyalty programs or table management. Other key factors to assess when selecting the best POS system are ease of use, integration with your current providers (accounting, payments, or e-commerce), how easily you can access customer support, and cost.

The only ongoing cost is a low 1.1% transaction fee on Visa and Mastercard domestic card payments accepted through Zeller Terminal, with no hidden charges for refunds or chargebacks.

Zeller POS Lite is free and comes built-in to Zeller Terminal , with no lock-in contracts, setup fees, or monthly charges. Simply purchase a Zeller terminal to get started. You’ll benefit from low transaction fees, an award-winning design, and 24/7 support.

To use the Zeller POS System, merchants require at least one Zeller Terminal, available for a one-time purchase price. An iPad or Android tablet or smartphone with the free Zeller POS app installed is required. A LAN-connected receipt printer and cash drawer are optional additions for businesses who need to print receipts, order tickets, or accept cash payments.

Zeller POS Lite comes built-in to Zeller Terminal and App, and is also free. To get started, simply purchase a Zeller Terminal from the Zeller Shop, connect it to Wi-Fi or a Zeller SIM card, and follow the instructions to create an item library either from Zeller Dashboard, Zeller App, or directly on Zeller Terminal.

Zeller POS runs on any modern iPad or Android tablet, paired with Zeller Terminal to process card payments. It supports any LAN-connected ESC-P compliant receipt printer — including the Star Micronics TSP143III and Epson TM-m30 — with cash drawers connecting to the receipt printer via an RJ12 cable.

A traditional cash register is a standalone device designed to process cash transactions and store money securely. It calculates totals, opens a drawer, and prints a receipt, but it has no visibility into what's selling, no connection to your inventory, and no ability to accept card payments without a separate terminal alongside it.

A modern POS system does all of that and considerably more. It processes payments across multiple methods (card, contactless, mobile wallets, and cash), while simultaneously updating your inventory, recording the transaction against your sales data, and making that information available in real time through a dashboard or app. It can manage your item catalogue, generate reports, handle refunds, print kitchen dockets, manage staff access, and integrate with your accounting software.

Most cloud-based POS systems offer some form of offline functionality, typically allowing you to continue processing cash sales and storing transaction data locally, which then syncs back to the cloud once your connection is restored. However, card payments almost always require an active internet connection to process, since they rely on real-time communication with payment networks.

Some systems (including Zeller POS) use a local-first architecture, meaning your product catalogue and core functions remain accessible even when connectivity drops, so staff aren't left staring at a blank screen, however you will not be able to accept card payments while offline. However, Zeller Terminal offers multiple connectivity options (Ethernet, WiFi, and 4G SIM), so if your WiFi drops out, you can switch to mobile data to continue accepting payments.

Cost and contracts: Square, Lightspeed, and Shopify charge ongoing monthly subscription fees, while Clover is frequently sold on long-term contracts that are costly to exit. Zeller POS is free to download and free to run, with no subscription, no licence fee, no lock-in contract, and no cancellation fees.

Transaction fees: Square and Clover fees vary by plan, card type, or reseller. Shopify and Lightspeed impose additional fees on merchants who don't use their preferred payment processors. Zeller charges 1.3% for domestic Visa and Mastercard payments, with no hidden charges for refunds or chargebacks.

Hardware flexibility: Clover, Lightspeed, Shopify, and Square use hardware tied to their own ecosystems — switch providers and your terminal typically can't come with you. Zeller POS runs on any iPad or Android tablet, and Zeller Terminal integrates with leading third-party POS systems, so it stays useful even if you ever change your POS software.

Features and add-on costs: Clover, Lightspeed, and Shopify often require paid add-ons or higher-tier plans to unlock advanced features. Zeller POS includes kitchen printing, cash drawer connectivity, notes, pricing controls, inventory management, staff access management, and reporting — all included, at no extra cost.

Built for retail and hospitality: Shopify is primarily an ecommerce platform, and several competitors require additional integrations to support hospitality workflows. Zeller POS supports kitchen docket printing, cash drawer connectivity, item and order-level notes, and variable pricing out of the box.

Customer support: Square, Clover, and Shopify have faced widespread criticism for slow response times and difficulty reaching a human agent. Zeller offers 24/7 support via phone, email, and SMS, with local account managers available for on-site assistance.

Fund settlement: Square and Shopify settlement times vary by plan. Clover merchants have reported difficulties accessing funds. Zeller settles funds nightly into a merchant's Zeller Account, every day without exception.

All your business finances in one place: Clover, Lightspeed, and Shopify focus primarily on POS and payments. Zeller combines POS, payments, a business account, corporate debit cards, and online invoicing into a single platform — one login, no reconciliation across separate systems.

Zeller POS is an electronic point-of-sale system (ePOS) designed to help businesses take orders, process payments, manage products, and track sales from one place. Its intuitive interface makes it easy for new staff to learn, while features such as item-level notes, discounts, price overrides, and fast product search help teams serve customers quickly and accurately.

Switching from another ePOS system is simple, too. Import your existing product catalogue using a CSV file, then manage products, prices, SKUs, and categories from Zeller Dashboard. Real-time sales reporting gives you an up-to-date view of revenue, best-selling products, and trading performance from any device.

Zeller POS also connects your point-of-sale system with your wider business finances. Manage payments, sales, refunds, invoices, and business banking from a single Zeller account, with funds settling directly into your Zeller Business Account.

An ePOS system for hospitality businesses

Zeller POS is built for cafés, coffee shops, restaurants, pubs, and bars. Take orders quickly, add item modifications and special instructions, and send orders directly to the kitchen with automatic docket printing and order numbers. 

Connect compatible cash drawers and printers, while item and sale-level notes help front-of-house and kitchen teams communicate clearly. Zeller’s ePOS system also supports features such as variable item pricing, discounts, and manager-authorised price overrides, giving hospitality teams greater control at the point of sale.

An ePOS system for retail businesses

Zeller POS helps retail businesses manage products, process sales, and keep track of performance from one intuitive system. Search products by name, category, SKU, or barcode, while product variants, discounts, and price overrides make it easier for staff to manage different products and pricing at the register.

Beyond your POS system, Zeller gives you access to business tools including invoicing, business accounts, and debit cards. Funds from your Zeller payments settle directly into your Zeller Business Account, helping you manage more of your business finances from a single platform.

When you choose Zeller POS, help is available 24/7 by phone, email, and SMS. You can speak to a real person whenever you need support, including outside standard business hours.

Zeller POS is also designed for a straightforward setup, with no technician required. Most businesses can get their POS system up and running and start taking payments on the same day they sign up. Local account managers are also available to provide hands-on support when required.
