Hi there. Does anyone know a good plug-in or software that can allow customers to pay via clicking a link that will work well with NetSuite? What I am hoping to do is to attach a link in the invoice which will allow customers to key in their credit card information and make payment. As an added bonus, this software would be able to automatically apply payment in NetSuite or via a workflow.

I've run across this solution from Prolecto before https://blog.prolecto.com/2018/06/09/netsuite-video-demonstration-accept-credit-cards/

I think stripe offers this functionality, but I haven't used them so can't comment 100%

There is also EzyCollect / SimplyPaid which I have come across in the last but haven't personally used

I used PayStand at my old company, haven't used it in depth because I left right after we got it, but from what I saw it was pretty neat

tipalti is a thing, although I've only played with it

A friend designed a solution for this.

SCSCloud.com has a ePay email solution for Invoices and Sales Orders either manually or auto send. The actual CC processing is done in your NS account and a Payment record created on the Invoice or a Customer Deposit on the Sales Order.
