Unable to create e-invoice with "Pay Now" link. I'm not having an issue sending the invoice to Outlook.

Hello efarmer,

Thanks for reaching out to us here in Community.

If you are wondering why you keep on getting this error, you can try to update QuickBooks Desktop to the latest release.

Since you're running QuickBooks 2015, you need to be at least on release 6 or higher to let the customer pay online. You can click Help> Update QuickBooks and install any available updates Quickbooks 2016 has the ability to e-invoice from R1 and up.

When creating the invoice, you need to make sure to enable it for online payment. This can be done in the preferences as well under the Payments option.

You can check out this article for more information: “View and Pay Invoice” button missing when emailing e-invoices from QuickBooks 2015 and 2016?

Feel free to leave a comment if you need anything else.

Server Connection Error - Something went wrong. Try again to send an e-Invoice. Alternatively, you can choose to send a regular invoice without the "Pay Now" Link. I had this same issue and after a lot of trial and error, figured out that it was because my client had a prior merchant account that was replaced with a new merchant account. The invoices that were created while the prior merchant account was active and linked to the QB database would yield the Server Connection Error message while the invoices that were subsequently created after the new and current merchant account was linked to the QB database would not yield that error. The solution was to go back and delete and recreate the invoices that were created under the prior account (can duplicate invoices and delete originals). The recreated invoices were able to send out without the error. Sure wish the error would have been a little more helpful in figuring out the true issue we had.
