DESCRIPTION

This module is tool to help construct ACH files, which are fixed-width formatted files accpected by most banks. ACH (Automated Clearing House) is an electronic banking network operating system in the United States. ACH processes large volumes of both credit and debit transactions which are originated in batches. Rules and regulations governing the ACH network are established by the National Automated Clearing House Association (NACHA) and the Federal Reserve (Fed).

ACH credit transfers include direct deposit payroll payments and payments to contractors and vendors. ACH debit transfers include consumer payments on insurance premiums, mortgage loans, and other kinds of bills.

CONFIGURATION

The parameters below can be passed to the constructor new in a hashref.

company_id

Required. Your 10-digit company number; usually your federal tax ID.

company_name

Required. Your company name to appear on the receiver's statement; up to 16 characters.

entry_description

Required per batch. A brief description of the nature of the transactions. This will appear on the receiver's bank statement. Maximum of 10 characters.

destination

Required per file. The 9-digit routing number for the destination bank.

destination_name

Optional per file. A 23-character string identifying the destination bank.

origination

Required per file. This will usually be the same as the company_id.

origination_name

Required per file. This will usually be the same as the company_name, but note that it can be up to 23 characters long.

company_note

Optional per batch. For your own internal use. Maximum 20 characters.

effective_date

Optional per batch. Date in yymmdd format that the transactions should be posted.

DETAIL RECORD FORMAT

The make_batch function expects entry detail records in this format:

 {
   customer_name    => 'JOHN SMITH',   # Maximum of 22 characters
   customer_acct    => '0000-0111111', # Maximum of 15 characters
   amount           => '2501',         # In whole cents; this is $25.01
   routing_number   => '10010101',     # 9 digits
   bank_account     => '103030030',    # Maximum of 17 characters
   transaction_code => '27',
   entry_trace      => 'ABCDE0000000001', # Optional trace number
 }

Only the following transaction codes are supported:

 22 - Deposit to checking account
 27 - Debit from checking account
 32 - Deposit to savings account
 37 - Debit from savings account

Rules for the entry_trace may vary. An example institution requires the first 8 characters be the destination bank's routing number (excluding the final checksum digit), and the next 7 characters be a zero-filled number incrementing sequentially for each record.
