The starting point
Most restaurant POS systems on the Hungarian market are subscription-based and run in the cloud. For small cafés, eateries, pizzerias, snack bars and food trucks we wanted a system that costs less, runs on your own hosting or on the computer behind the counter, and still does everything daily operation needs. Not a copy of a big system, but a deliberately smaller and simpler one.
What we built
- POS: basket, VAT by eat-in or takeaway, sizes and toppings, tips, discounts, five payment methods (cash, card, SZÉP card, voucher, transfer), split bills and partial payments.
- Floor plan editor: rooms and tables by drag and drop, moving and merging tables.
- Menu: groups, categories, photos, allergens, options, and a drag-and-drop menu designer.
- Kitchen display: colour by delay, "done" per item, sound alerts.
- QR table ordering with waiter approval, and a printable photo menu with QR code, in several languages.
- Online table booking, approved by staff.
- Online ordering: customer accounts, pick-up or delivery, card payment, notifications.
- Delivery: zones and fees by postcode, a courier app, live tracking for the guest.
- Pager: for self-service pick-up, as a phone-based and a physical version.
- Printing and closing: 58/80 mm receipts, cash drawer, daily financial close by VAT, payment method and channel, with export.
- Roles and permissions, automatic and manual backups.
The system issues non-fiscal receipts; it does not replace the cash register but works alongside it.
Integrations and technology
PHP 8 and SQLite with no framework and no build step, as an installable web app. It runs in two ways: one folder per restaurant with its own database, or on the rendella.hu platform, where the code is shared but each restaurant's database and files are separate, and an operator console manages subscriptions and backups. Integrations: SimplePay card payments with each restaurant's own merchant account, Telegram and SMS notifications, silent receipt printing via QZ Tray, OpenStreetMap-based maps, machine menu translation.
How it went
The first working version was ready on 20 May 2026. QR ordering followed at the end of May; on 3 June the multi-restaurant rendella.hu platform went live; by mid-June booking, print control and the full online ordering chain, from payment to the courier app, were in place. Every module started with a written specification.
Where it stands
The rendella.hu platform is running with a public demo restaurant, and the system is currently in test operation; no restaurant uses it in production yet. Every item of the first phase is done. Next up: reporting to the national tourism data system (NTAK), invoicing software integration, a loyalty programme and inventory.
