US NACHA ACH File Generator
Generate bank-ready ACH origination files (PPD / CCD / CTX) for vendor and payroll payments — upload straight to your bank, no gateway, no per-transaction fees
Build NACHA-compliant ACH origination files inside Odoo and upload them directly to your bank's cash-management portal. Every record follows the NACHA Operating Rules fixed-width layout — 94-character records, 10-record blocking, correct entry hashes, trace numbers and block counts — so files clear validation on the first attempt. Your account data never leaves your database.
PPD, CCD & CTX entry classes
Originate consumer payments (PPD — payroll, refunds), corporate business-to-business payments (CCD), and Corporate Trade Exchange (CTX) with multiple EDI / ASC X12 addenda records per entry. Credits and debits against checking or savings accounts, plus zero-dollar pre-notification entries.
Balanced & unbalanced files
Toggle a balanced file and the module appends an offsetting settlement entry so total debits equal total credits — exactly what many ODFIs require. Or send an unbalanced file and let the bank book the offset. The choice is per batch.
Real ABA routing validation
Every routing number is checked with the federal 3-7-1 modulus-10 checksum and the Federal Reserve routing-symbol range test — on the bank record, on each receiver entry and on your company configuration. A single bad routing number no longer gets the whole file returned.
Build a batch from vendor bills
Select posted vendor bills and the wizard turns them into a ready ACH
batch, grouping the amount due per payee from their stored bank account.
Review entries, generate the file, download the .ach, mark
it sent — a full workflow with chatter audit trail.
Correct down to the column
File Header (1), Company/Batch Header (5), Entry Detail (6), Addenda (7), Batch Control (8) and File Control (9) records are assembled with the same entry-hash, debit/credit totalling, trace-number assignment and all-nines block padding the ACH operator re-derives on receipt. Originator settings — company name and ID, immediate origin and destination, ODFI routing and the offset account — are all editable from Settings › ACH Payments.
BYOK & privacy
This module only builds the ACH text file for you to upload to your bank. It transmits nothing to any external service. Your routing and account numbers stay in your own Odoo database.
Compatible with Odoo 18 and Odoo 19.
