Sending document on Android
Updated over a week ago

Using your email address

You can send documents from your own email address as PDF files. You may not get opening notifications, depending on your client's mailbox.

Navigate to ⚙️Settings - Client communication and turn on "Send with iOS mail" or "Send with mail app"

iOS: Billdu uses your native iOS mail app to send emails

Android: Billdu checks, if you use Gmail app. Otherwise it opens a dialog with multiple emailing choices

Note: When you use your own email app, invoices and other documents are sent as PDF files by your email app.
