We covered the initial creation and design of the app, and now we’re ready to take it to the next level. In this follow-up article, we will discuss the implementation of additional features such as payment history tracking, inventory management, and overall optimization to enhance the app’s performance and usability.
Adding a Payment History Feature:
To help users keep track of their transactions, I’d a payment history feature to the POS app. This feature will display a list of all completed transactions, including details such as date, time, items purchased, and the total amount paid. To achieve this, we will create a new screen with a list view that fetches data from the app’s database and displays it in a user-friendly format. Users can also filter the list by date, payment method, or other criteria to easily find specific transactions.
Implementing the Order Feature:
The order feature allows users to create and manage a list of items that customers want to purchase. This is a crucial aspect of any POS app and will help streamline the transaction process.
The invoice will be sent to the customer’s email, thereby reducing paper usage. If tap “Place New Order” will be back home page.
