Is there a way to add payment details to invoices permanently so I don't have to write it in everytime?

Yes. You can add payment details to invoices permanently, but only through the web and not through the mobile app.

However, once set up on the web, those settings carry over to invoices sent from the mobile app. Here's how:

1. Click the Gear icon (⚙) and select Account and Settings.
2. Select the Sales tab on the left menu.
3. Click the Pencil icon to edit the Invoice payments section.
4. Enter your bank routing/account numbers, or other instructions in the Payment instructions box.
5. Click Save.
