NACHA Addenda Extension for Odoo

Adds 05 Addenda records and correct Entry/Addenda counts to Odoo`s l10n_us_payment_nacha.

This lightweight extension enhances Odoo`s native NACHA ACH export by emitting a single 05 Addenda record per payment (when a memo is present), setting the Addenda Record Indicator, and fixing the Entry/Addenda Count in Batch (record 8) and File (record 9) control records. No new menus or models - just compliant output, out of the box.

Key Features

05 Addenda support - Adds one 05 record per payment when Memo is set (up to 80 characters).
Addenda Record Indicator - Column 79 automatically set to 1 when addenda exists, otherwise 0.
Correct Entry/Addenda counts - Batch (record 8) and File (record 9) totals include addenda.
Seamless integration - Works with account.batch.payment; no extra steps or configuration.
Minimal & safe - Python overrides only; no database schema changes.

Why you need this

Many U.S. banks require payment information (invoice number, reference, etc.) in ACH files. Odoo`s standard NACHA export does not include 05 addenda by default. This extension ensures your files are NACHA-compliant and accepted by banks without manual edits.

Terminology: ACH is the U.S. electronic payments network; NACHA is the governing body and file-format specification. This module focuses on the NACHA file format.

Compatibility

Odoo 18.0
Depends on Odoo Enterprise addon l10n_us_payment_nacha
Works on Odoo.sh, On-Premise

Installation

Install official l10n_us_payment_nacha.
Install this module us_payment_nacha_memo.
Generate ACH/NACHA file from Accounting → Batch Payments as usual.

How it works

If a payment`s Memo is set, the export adds a single 05 addenda with that memo (trimmed/padded to 80 chars).
The addenda indicator on the entry line is set to 1.
Batch/File control records include the addenda in the Entry/Addenda counts.

Note: If your bank requires multiple 05 addenda per entry, contact support - this extension can be adapted.

What`s included

Python overrides of: _generate_nacha_entry_detail, _generate_nacha_batch_control_record, _generate_nacha_file_control_record.
No UI changes, no extra configuration.
