A point-of-sale (POS) system records sales and supports the steps around a transaction. Depending on the product, it may connect payments, receipts, product information, stock, staff access and reporting. The five types below describe both how a POS is deployed and the business workflow it serves. They are not mutually exclusive: a restaurant POS, for example, may also be cloud-based and run on tablets.
1. Countertop or fixed-terminal POS
A fixed POS is used at a checkout counter with suitable terminals and peripherals such as a receipt printer or barcode scanner. It can suit a business with a stable payment point and high transaction volume. Check hardware compatibility, support arrangements, offline behaviour and how records are backed up before choosing a setup.
2. Cloud-based POS
A cloud-based POS stores or synchronises data through an online service, allowing authorised staff to view sales and manage settings across locations where the product supports it. Compare how it works during an internet outage, where data is held, the subscription terms, user permissions and how data can be exported if you later change systems.
3. Mobile POS
Mobile POS systems use a phone, tablet or portable terminal so staff can take an order or complete a sale away from a fixed counter. They can be useful for pop-up events, field sales, queue reduction or table service. Confirm the supported devices, payment method, receipt options, connectivity and device-management process.
4. Restaurant and food-service POS
Food-service workflows may need menus, modifiers, table or queue management, kitchen order routing and split bills. A takeaway outlet, café and multi-site restaurant will have different needs. Walk through a real order, including changes and refunds, to see whether the POS fits daily operations and connects to any delivery or accounting tools you use.
5. Retail POS
A retail POS commonly focuses on product catalogues, prices, promotions, returns and stock movements. Businesses with more than one store or an ecommerce channel should check how item codes, stock balances and sales data stay consistent. Ask how the system handles exchanges, partial returns and stock adjustments, not just a straightforward sale.
What to compare before selecting a POS system
- Sales workflow: test common transactions and exceptions, including refunds and cancelled orders.
- Stock: decide whether basic item balances are enough or a separate inventory or warehouse system is needed.
- Integrations: confirm the actual connection to accounting, ecommerce, CRM or other existing software.
- Access and reporting: define who can change prices, issue refunds and view sales data.
- Costs and ownership: compare hardware, subscriptions, payment fees, migration, support and access to your records.
A POS is only one part of a wider business workflow. If sales, stock and purchasing are managed in different systems, decide which one owns each record and when updates should be exchanged. For larger warehouse processes, see our guide to inventory software and our warehouse management system service.
When custom integration may help
ADSM Tech develops business management systems and integrations for workflows that standard tools do not cover well. If your POS needs to exchange information with an existing ERP, distributor process or custom application, the first step is to map the data and available integration methods. The right approach depends on the POS provider’s capabilities and your operational requirements.
