Why businesses choose our developer-friendly API

“The ACHeck21 Software coupled with the Canon CR-180 has truly been an enhancement in our back office processing. The speed at which we can process the bulk payments is amazing. Our biggest problem is getting the mail opened fast enough to keep the scanners busy.”

Michelle McBride - St. Charles County (MO)

Why businesses choose our developer-friendly API

“I know ACHeck21 has been referred to as the “Microsoft” of the ACH world and it is TRUE!!! I can truly say that this system works because I have been an end user for many years. In March 2007, we started utilizing the ACHeck21 method as well as continuing with the ACH. What an awesome system!!!! It kept me from having to hire 2 employees years ago just to keep up with the mail that was coming in from a fast growing community. It would take 4 employees just to post payments manually every day but after sending items electronically, the process was cut to approximately 1½ hrs daily for 1 employee.”

We have worked with numerous processing partners in the past for our ACH needs – including direct relationships with banks. The service, reporting, and technical staff that DCS provides all of us is really unmatched. Our customers are very happy with the relationship – and we have been able to build upon these relationships with new products such as Check 21 and Remote Capture. It’s been a great partnership for us.”
