My supplier sends me invoices for material via email. am i able to automatically sync that with quickbooks to show me which invoices are outstanding?

Hi there, @userliamveryard.

It is not possible to sync your supplier's invoices to your QuickBooks account via email. You'll have to manually create bills to record these transactions in QuickBooks Online (QBO). 

Let me show you how:

1. Click the +New icon and select Bill. 
2. Choose a vendor in the Vendor drop-down list.
3. Select the category in the CATEGORY drop-down menu and enter the amount.
4. Fill out the rest of the fields and select Save.
5. Repeat these steps to record the rest of invoices that was sent to your email.

If you already paid the invoice, simply select Mark as Paid in the Bill window. Then, select Save and close.

In addition, you can run the Bills and Applied Payments report in QBO. This will show you the list of payments you’ve made and the bills that go with them. Just go to Reports and look for the Bills and Applied Payments report.
