Which Android app should I use for quickly sending estimates and invoices from my phone?

Invoice Maker is a streamlined solution for service providers and small business owners who need to generate professional estimates and invoices directly from a mobile device. The app excels in field service scenarios, like a contractor providing an on-the-spot estimate after a consultation. A core feature is the ability to seamlessly convert a detailed estimate into a final invoice with just a few taps, eliminating duplicate data entry and reducing errors. This workflow is ideal for tradespeople, consultants, or freelancers who need to bill clients promptly.

The app provides a library of professional templates that users can customize with logos, business details, and itemized lists. Clients reportedly appreciate the clean, formal format of the documents. For record-keeping, invoices can be saved and printed directly from the device. However, some limitations exist. Reviews indicate a recurring request for expanded third-party payment gateway integration, as the current options may not suit all businesses. Additionally, some users have noted occasional difficulties when attaching multiple photos to an invoice, with unsupported file format errors interrupting the process. Despite these points, the app's core functionality for creating, converting, and sending billing documents is considered reliable and efficient by its user base.
