Invoice2pdf is a free Android app developed by dNT that enables small businesses to create PDF invoices quickly and easily. The app is designed for users who send invoices infrequently and includes two types of invoices: SIMPLE, which is an invoice without any taxes, and VAT, which is an invoice with value-added tax used in various countries such as Europe, China, India, Mexico, and Bangladesh.

One of the main features of Invoice2pdf is that it stores your company information locally on your device. This means that you can create and save invoices on the go without needing an internet connection. Invoices are stored in PDF format on your device's SD card, making it easy to share them with your clients via email or other messaging apps.

Although Invoice2pdf is supported by ads (Google AdMob), it doesn't detract from the app's usability. The ads are non-intrusive and don't hinder the app's functionality.

Overall, Invoice2pdf is a useful tool for small business owners who need to create invoices quickly and efficiently. It's easy to use, stores your information locally, and generates professional-looking PDF invoices that you can share with your clients. If you're a small business owner looking for a simple invoicing solution, Invoice2pdf is definitely worth checking out.
