Welcome to the Community, @jhalpinplasterin. I'll be sharing some insights about customizing invoices using the mobile app.
You can customize an invoice and logo in the template using a mobile app. However, this is only available in IOS. It is still not available in the android version.
If you want to do it on an IOS mobile, follow the steps below:
- Go to Settings, then Sales Forms.
- Choose the Customize Invoice template from the drop-down menu.
- Change your company's default logo, color, and footer message by following the on-screen instructions.
