Hi Randolph,
The web version of MYOB AccountRight doesn't have a feature to manually set a primary attachment or reorder documents once they're uploaded to a bill. We understand how important it is for the invoice to show up clearly, especially when multiple files are attached.
As a workaround, you could try uploading the invoice last (after all supporting docs), as sometimes the system picks the most recently added file to show first, though we know this isn't always consistent.
If this feature is essential to your workflow, we'd definitely recommend submitting it to our Ideas Board. That's the best way to get in front of our product team and help influence future updates.
Regards,
Sai
