Inventory Control

We sell pavers, travertine, stone, take a look https://www.vegasstonebrokers.com/stone-pavers#ConcretePavers. I need a basic app to get and display data from QuickBooks, this app will be used to check availability of materials and as well to check the price of items. preferred tools, native react and for database PostgreSQL. This app will be used to post materials to QuickBooks, only admin users will be able to perform this task. I want the search bar to be the main method to find information on the app, there will be buttons as well. The idea is like this, we get a truck full of pallets, people get out of the office to check if the loads are correct and later they will insert it manually on quickbooks, I want simplify this by just unlocking the phone, open the app, press a add button go to the search bar, type the product name, select the product, and add to the existing quantity, IMPORTANT, we need a date field to register the date of the increase. I have some pictures and ideas, I developed the design, but i am open to suggestions.
