Any way for the program ETO to communicate with ETO?Can ETO communicate with ETO to create invoices?

Thanks for checking in with us. cc_staff.

All third-party applications (non-intuit) will no longer have access to their software. I'd suggest getting in touch with the ETO Support Team.

They'd be able to provide you with the steps on how to communicate and create invoices using their program.
