Point of sale system - Angular

We are looking for a point of sale system. The design should be similar to vendhq. This is purely a front end system. It does not need to communicate with a backend like a server/php/mysql. Requirements • Store all data in IndexedDB storage in browser. • Built using Angular • Separate component files for all modals and parts of the screen – the main screen should have at least 4 separate components (for the menu, categories, cart, menu bar) and the modals should be in separate files • Index/table stores should be branches, terminals,products, categories, users, payment methods, tables, discount_reasons, wastage_reasons, bills, items in bill, customers and anything else that is relevant Features • First modal – select branch (so one business has many branches like mcdonalds) then select terminal (mcdonalds will have at least 3 terminals etc) • Operator logins in via PIN code using a number pad (modal) on here display time current time • Select a department (top level menu) – so like the main menu, or takeaway menu, drinks menu • Then show the main screen (with categories/items, like pizza, burgers, and the items are aloo tikki burger etc) • Operator places an order • They can assign orders to a customer (modal) • They can assign orders to a table (modal) • They can increase/decrease the quantity of items • They can add product options (like sizes, like pizza toppings) • They can save order • They can reopen orders to add/edit/delete/void items • New items should have a flag, to distinguish what is already added to bill • Can discount bill with % and an absolute amount • They can pay off the order – so select to pay via cash or card (can select multiple tenders, so a $15 bill can be $10 cash, $5 cash) • Refund functions • They can print a bill (this will bring a modal showing the bill, doesn’t need to print). • Merge and split bills (for example, you might have 2 bills that you want to merge into 1 bill, or 1 bill that you want to split into 2 bills, with some items on one bill, and some items on another bill) • Can move bills to different tables • Bills can be paid off immediately or stored for later use etc. Ideally we want someone who has done something similar. If you have please post a short video demo. There are multiple phases to this project, we believe this phase will take 72 hours and then we will proceed to take phase. If you understand – please write in brief “I understand and have done a similar project before. I will complete in max 72 hours, I will send a demo of previous work. I will complete in Angular (NOT ANGULAR.JS) and use indexeddb”
