Like knowing you have a ‘terminal illness’, so is the upcoming demise of the Intuit Payment Network (IPN). On May 31, 2016, the ability to send invoices containing an IPN payment link and send payments with the Pay Vendor tool will come to an end, and the beginning of the IPN ‘death spiral’ will swirl for roughly another month as customers will still be able to pay any open invoices through your Pay Link until June 30, 2016. You will also be able to download IPN payments posted to your account and review all past transactions until that same June 30th date.
Intuit’s response to this change (on their part) is to suggest that you first consider switching to QuickBooks Online and begin using eInvoicing. If you only make use of the IPN Website, then you can start a new QBO (from scratch) file. For those using QuickBooks for Mac they can either transfer their Company data to QBO, or start a new file from scratch.
For those using QuickBooks (desktop), they will need to upgrade to a member of the QuickBooks (Windows desktop) 2016 product line so they too can make use of eInvoicing including the ‘Pay Now’ button technology for Invoices.
If you don't want to find yourself without electronic payment for invoicing capability they you may want to check out the Intuit Support Document for more details about this latest change, or contact Intuit Payments for more information about QuickBooks Payment Options that may fit your needs.
