Custom POS software development

Point-of-sale software, also known as POS software, is the system you use to take payment at the counter or table. It handles items and prices, calculates discounts and VAT, prints or emails the receipt, controls the payment terminal and records the sale against your stock. A good POS system connects the shop floor to your product management, inventory, reporting and accounting, so you always know what has been sold and what is in stock. Custom POS software lets you set this up around your own range, sector and way of working, rather than adapting your processes to a standard package.

We build custom solutions. A specialist shop with standardised products, a hospitality business with table management and a chain with dozens of branches all have very different requirements for a till system. Custom till software is matched to your range, pricing structure, discount rules and branch setup, and can grow with you if you expand or add a webshop. After an initial consultation, we agree together which functionality matters most and in what order to develop it, without promising a fixed timeline or price we cannot yet substantiate.

We integrate the till with the payment methods your customers use: card and contactless payments via a payment terminal, iDEAL and online payments via a payment service provider (PSP) such as Mollie, Adyen or Stripe, and of course cash. The payment terminal is controlled directly, so the amount appears automatically on screen and typing errors are avoided. Card details never reach the till unencrypted; payment traffic runs through PCI DSS-certified parties and in line with PSD2.

Yes. A till must keep working even if the internet or the central server goes down. We build an offline mode in which the till continues to work locally: you can take payments, print receipts and update stock. Once the connection is restored, the till automatically synchronises transactions with the central system, so revenue, stock and reporting are correct again. How robust the offline mode needs to be depends on your situation and the number of tills, which we determine together with you.

Yes. We integrate the till with your accounting package, for example Exact Online, Twinfield or Moneybird, so that revenue, VAT and end-of-day closings are posted automatically. For omnichannel, we connect the till to your webshop, such as WooCommerce, Shopify or Magento, so that items, prices, stock and customer data are shared between the shop and the webshop. That way you sell the same item only once and stock remains up to date across all channels.

The receipt shows the items sold, the prices, any discounts applied and the VAT, split by the standard and reduced rates where applicable. Transactions, receipts and daily closings are recorded and retained in line with the statutory retention requirement for your records, so that your sales administration remains complete and verifiable for HM Revenue & Customs and your accountant. We agree the set-up of VAT rates, returns and corrections with you and your accountant.

Yes. We build till software that grows with you from a single till to multiple tills per site and multiple branches. You manage products, prices and discount rules centrally and roll them out to all sites, while you can set different prices or promotions per branch. You see stock, turnover and daily closings in real time per till and per site, with consolidated reporting for the chain as a whole.

Payment traffic runs through PCI DSS-certified payment providers, so card details never end up unprotected in your till system. We process customer data for loyalty cards and reward schemes in line with the UK GDPR, with data minimisation, role-based access and logging of who views which data. Data is encrypted in transit and at rest, and we work to OWASP security standards with automated testing and monitoring.
