I am finishing a restaurant POS that runs on a multi-terminal setup all connected to a single server, and I need the cashier component wrapped up tonight. The whole solution is written in .NET MAUI, so I am only interested in someone who has already delivered at least one MAUI-based POS before; you should be comfortable configuring multiple front-of-house terminals that talk to a central back-office database in real time. Scope of this sprint The piece still missing is the cashier screen and its service layer. It must let the user create and manage dine-in or take-out orders, accept credit/debit cards and cash, close tickets, and instantly push stock deductions to the existing inventory management service. Once payment is confirmed the app needs to generate and print or email a receipt. All calls to the server are done through REST endpoints that are already in place; you only need to consume them. Deliverables for tonight • MAUI solution or project folder containing the new cashier module with clear build instructions • UI ready for a 10-inch Android tablet (XAML layouts only; styles already defined in the shared resource dictionary) • ViewModels and service calls wired to my existing API interfaces • Simple mock objects for card processing so I can swap in the live provider later • A quick read-me describing setup and how to run a multi-terminal test Acceptance checks 1. I can open the solution, restore NuGet packages, press run, and the cashier screen appears without errors. 2. Creating an order, adding two items, and closing it with “Cash” updates inventory and returns a receipt number. 3. Switching payment type to “Card” calls the provided ICardProcessor stub and still completes the sale. 4. Any change on one terminal is visible on a second emulator session within five seconds via SignalR push (already configured in the shell). If you are confident you can get this done before midnight (UTC-5) and have real MAUI POS experience, send the git link to one comparable project in your first reply and I will share the repo URL and credentials right away.
