Cash Receipt is a free mobile application developed by HuPaiWen for Android devices running on Android 4.4 or later. This app replaces traditional receipt books with digital receipts, allowing you to create, store, and send receipts on your phone or tablet. The application generates two versions of each receipt - a graphic receipt intended for sending as an attachment via email, messaging applications, or sharing files, and an SMS message optimized for sending using your device's SMS application.

Cash Receipt allows you to filter your receipt list by "received from," "received for," and date. It also supports English, Brazilian Portuguese, and Latin American Spanish languages. You can customize the receipt style, include an image as a logo/letterhead, add a header and footer, including the tax on MULTI-ITEM receipts, and set up a preset signature or sign each receipt separately. The application also allows you to export receipts to .CSV format and share them via file sharing, messaging, etc.

Overall, Cash Receipt is an excellent tool for small business owners and individuals who want to keep track of their financial transactions paperless and efficiently. However, it's worth noting that the app does not provide any warranty or guarantee of fitness for a particular purpose.
