From a Broken Build to a Live POS Platform in Six Months

1. The Challenge

Our client is a SaaS POS provider serving restaurants and amusement parks, including restaurants operating inside the parks. The product covered slot-based table bookings, park ticket sales, menu ordering and kitchen operations across several channels. When the client came to ThemeMakker, the product was unfinished and could not go live.

• A broken inherited system. The POS and Kitchen Display System (KDS) existed but were not fully functional. The code contained broken business logic and incorrect calculations.
• Modules that depended on each other, but didn't work together. Every module consumes and produces data for the others: bookings feed orders, orders feed the kitchen and inventory, and payments close the loop. The previous developers could not deliver this interdependent flow or build the new user journeys the client needed on top of it.
• Unreliable booking channels. Bookings through the POS, the self-service kiosks and the embeddable web widget all had issues that needed fixing before the product could be used in a live venue.
• Missing operational pieces. There was no working order management, and payment terminals and receipt printers were not yet integrated. Without them, no restaurant or park could run its day-to-day operations on the platform.

2. What We Did

A two-person ThemeMakker team took over the product, diagnosed its failures by root-cause analysis rather than patching symptoms, restructured the system, and completed the missing pieces. The full platform was built on Laravel as a responsive web application, so the POS, kiosk and KDS screens run on any device size.

• Fixed the core booking flows

  We fixed the POS booking, kiosk booking and web widget flows. Guests and venues can book slots through any of the three channels: online through a widget that the venue embeds in its own website as an iFrame, at a self-service kiosk, or through a POS operator.

• Built order management and the Kitchen Display System

  We added order management and a working KDS. Orders placed through the POS or kiosk, from menus generated by the product management system, now flow to the kitchen screens in one connected process.

• Integrated payment terminals and receipt printers

  Guests can pay at the kiosk or through a POS operator using integrated online payment terminals. Receipt printers are connected to the system through port-based communication, so receipts print as part of the transaction.

• Extended product, inventory and floor map management

  Product management and floor map management were already functional. We added new configurations and improved them to the client's requirements, including item availability driven by inventory, so menus only offer what can actually be served.

• One admin panel for the whole platform

  Every component of the system, from booking slots and menus to devices and floor maps, can be configured and managed from a central admin panel.

3. Outcomes

The platform has been live for two years.

• Live MVP in six months: The client went from a broken, unfinished build to a live product in about six months, an outcome the client had considered impossible.
• 30% less operational time at venues: Parks and restaurants using the platform spend 30% less time on operations than with their previous manual approach.
• A complete, connected product: Bookings, ticketing, ordering, inventory, kitchen, payments and printing now run as one system, delivered by two developers in around eight months.
• Stable for two years in production: The platform has run in live venues for two years since launch.
