Thank you for reaching out to us, @Direction.

I'll be happy to provide a bit of advice on your invoices related to SaasAnt. Since it is a Third-party application, I would suggest contacting SaasAnt in this way, we can verify if the connection can be automated with QuickBooks Online.

You can also check on this article: Create recurring transactions in QuickBooks Online for more information about invoices.

We're always here in the Community to help if you have other questions related to QuickBooks. Stay safe!
