It's good to see you here in the QuickBooks Community, @Erics29.
I'll share some information about managing invoices with the ACH link and help you from there.
When you process online invoice payments, the ACH link will only be available if you create and send the invoice within your QuickBooks Desktop (QBDT) company file. Thus, imported invoices don't include the ACH link when sending the invoices to your customers.
I understand that you have a lot of invoices to import and its time consuming to send them one at a time to your customers. Therefore, you'll need to create and send the invoices within QuickBooks to include the ACH link.
You can check out this article to learn more about processing payments in QBDT: Take and process payments in QuickBooks Desktop.
Just in case you want to know when QuickBooks deposits customer payments into your bank account, feel free to read this article for more information: Find out when QuickBooks Payments deposits customer payments.
