The Goldshop Manager App is a software tool designed to assist goldshop owners in managing their business operations. The app includes an inventory system that allows users to keep track of their stock of gold, as well as the current market value of their gold. The inventory system can also be used to track the amount of gold that has been sold or mortgaged, as well as any other transactions that have taken place.

The app also includes a mortgage system that allows users to enter the details of a mortgage, including the amount of gold being mortgaged, the duration of the mortgage, and the interest rate. The app will then calculate the total amount of interest owed over the course of the mortgage, as well as the final amount that must be paid in order to redeem the mortgaged gold.

In addition to the inventory and mortgage systems, the app also includes a selling system that allows users to enter the details of a sale, including the amount of gold being sold, the current market price, and any applicable taxes or fees. The app will then calculate the total amount that must be paid by the buyer, as well as the profit that the goldshop owner will make on the sale.
