POS System for Takeaway

Need a simple takeaway POS for my existing Windows 11 touchscreen till, connected to an ordering website on my own domain. The system must support touchscreen food buttons, sizes and extras, walk-in and telephone orders, and customer name, phone, and delivery address. Website orders should appear automatically on the same till with an audible alert and kitchen printing, if printer compatible. Payments are cash on delivery or collection; my separate myPOS card terminal does not need integration. I must be able to edit menu items and prices myself. Please use an existing reliable system, not expensive custom development. Target setup budget is €300–€400, with no compulsory monthly subscription or per-order commission. Disclose all hosting, licence, and renewal costs. Include installation, testing, training, and full admin access, and show a similar working system before starting.
