How to choose and set up a point of sale (pos) system

To get your shop up and running, you need a POS system that combines ease of use with robust inventory tracking. For most new UK retailers, the most efficient approach is a cloud-based system that runs on a tablet, allowing you to manage sales, track stock levels, and process VAT-compliant receipts from one central hub.

Choosing the right POS software

In the UK market, you have several excellent options such as Square, Zettle, Shopify POS, or Lightspeed. When comparing systems, look beyond the monthly subscription fee and consider the "payment processing fee" (usually a percentage of every sale). Choose a system that integrates seamlessly with your accounting software to make your tax returns easier later on.

Consider these essential features during your search:

• Inventory Management: Does it allow for size and colour variations?
• Reporting: Can you see which items are your bestsellers at a glance?
• Connectivity: Does it work offline if your shop's Wi-Fi drops out?
• VAT Compliance: Can it automatically apply the correct 20% VAT to your sales?

Sourcing your hardware

Modern POS systems are modular, meaning you can often buy the components separately or as a bundle. At a minimum, a standard clothing or gift shop will require the following hardware:

Hardware Item	Purpose
Tablet or Terminal	The main interface where you and your staff input sales.
Card Reader	Must support Chip & PIN, contactless, and mobile payments (Apple/Google Pay).
Thermal Receipt Printer	To provide customers with physical proof of purchase.
Cash Drawer	To securely store notes and coins for cash transactions.
Barcode Scanner	Speeds up the checkout process and reduces manual entry errors.

Configuring the system

Once your hardware arrives, follow these steps to get the system ready for your first customer:

1. Connect your hardware: Plug in your printer and cash drawer. Pair your card reader to your tablet via Bluetooth or Wi-Fi.
2. Import your products: Use a CSV file (a type of spreadsheet) to bulk-upload your products. Include the item name, price, SKU (Stock Keeping Unit), and current stock levels.
3. Set up your tax: Ensure the system is set to the standard UK VAT rate (20%) or "Zero Rated" for items like children's clothing where applicable.
4. Customise your receipts: Add your business logo, shop address, VAT registration number (if you have one), and your returns policy to the bottom of the receipt.

Pro Tip: Always run a "penny test" before you open your doors. Process a transaction for £0.01 using your own card to ensure the money reaches your account and the receipt prints correctly.

Training and staff access

If you have a team, create individual staff accounts with unique PINs. This allows you to track who processed which sale and prevents unauthorised staff from issuing refunds or seeing sensitive financial reports. Keep a simple "cheat sheet" near the till for common tasks like processing a return or applying a discount code.
