python-ach

ACH file generator module for python. So far, this has been tested with “PPD” and “CCD” batches with addenda records.

Example

Below is an example of how to use the module:

from ach.builder import AchFile

settings = {
    'immediate_dest' : '123456789', # Your bank's routing number
    'immediate_org' : '123456789', # Bank assigned routing number
    'immediate_dest_name' : 'YOUR BANK',
    'immediate_org_name' : 'YOUR COMPANY',
    'company_id' : '1234567890', #tax number
}

ach_file = AchFile('A',settings) #file Id mod

entries = [
    {
        'type'           : '22', # type of
        'routing_number' : '12345678',
        'account_number' : '11232132',
        'amount'         : '10.00',
        'name'           : 'Alice Wanderdust',
        'addenda' : [
            {
                'payment_related_info': 'Here is some additional information',
            },
        ],
    },
    {
        'type'           : '27',
        'routing_number' : '12345678',
        'account_number' : '234234234',
        'amount'         : '150.00',
        'name'           : 'Billy Holiday',
    },
    {
        'type'           : '22',
        'routing_number' : '12323231',
        'account_number' : '123123123',
        'amount'         : '12.13',
        'name'           : 'Rachel Welch',
    },
]

ach_file.add_batch('PPD', entries, credits=True, debits=True)

print ach_file.render_to_string()

This returns the following NACHA file:
