Hi there, stuart14.
I'm glad to have you here and be able to share some information about adding an attachment in expense via mobile app.
It’s never been easier to take control of your documents and put them all in one place, so you can access them anytime and anywhere. Sounds great that you already know the file of the images of your phone. However, we can only view the attachment in the maximum size indicated to QuickBook after we upload it in QuickBooks.
Also, we have limited file types that you can use to the images: Here are they:
- PDF
- JPEG
- PNG
- DOC
- XLSX
- CSV
- TIFF
- GIF
- XML
I would like to add this article: Attachments in QuickBooks Online. We can surely get additional information about editing, deleting, and adding them to a type of transaction.
If you need further help with it, please let me know by commenting below. I'm always around to guide you and provide some information that you need. Thanks for dropping by. Take care!
