I am trying to generate a bank NACHA (national automated clearing house association) file with my customers payment details to submit to my bank on a regular basis. Our site is built in PHP and though we could probably build the file ourselves, I was curious if anybody knew of any existing scripts or even reference guides for others who have done so using PHP.
I have searched around Google pretty hard unsuccessfully so any assistance is appreciated.
Thank you for your time.
Most businesses that need to create these files are .net houses. You might have better luck finding something in C# and reverse-engineering it.
I also needed such a thing... didn't find one so I made one.
The National ACH Association "NACHA" publishes the ACH rules on an annual basis. The current version, "2012 NACHA OPERATING RULES & GUIDELINES", contains the ACH rules, along with ACH file formats (i.e. Reference Guide) for creating your own tools to build ACH files.
