Accounts Receivable Retry

Orders that have declined payments can automatically route to your Accounts Receivable. UltraCart will automatically email the customer letting them know that there is a problem with their payment and provide a link to self-service update the information. In addition to emailing the customer UltraCart can automatically re-attempt the payment on a schedule that you define. Often times orders will go through on an automated attempt the next day.

Just wanted to let you guys know that CenterForLit.com has been an UltraCart customer for nearly ten years. All it ever does is exactly what I want and more. I couldn't be happier.

Ultracart integrates nicely with our website, and handles all of the transactions. We've written a script that pings the UC API and gets us pertinent data for our CRM.

Eric Somido

When we switched to UltraCart, we experienced a substantial increase in sales within two months which we attribute to the added capabilities that we obtained by using UltraCart.
