The easier you make it for your customers to pay, the easier you can collect.
SL QuickCollect is payment solution for Dynamics SL that allows you to email or SMS message out a simple link to your customer as a request for payment. The customer can then click on the link and are sent to a PCI compliant payment page without any portal login required. Everything integrated directly with Dynamics SL.
