Associated Bank NACHA file requirements
Associated Bank accepts NACHA-format ACH files through Associated Connect. The bank calls the feature "Import Profiles (profile type: ACH NACHA)". Here is what its published documentation requires.
Independent documentation. Not affiliated with or endorsed by Associated Bank.
Before you upload, run the file through the free ACH file validator. It checks the structural rules and Associated Bank's documented quirks in your browser; the file never leaves your computer.
How Associated Bank ACH file upload works
- Imports run through saved Import Profiles; NACHA is a built-in profile type.
- Files that contain offset entries need the "balanced file processing" checkbox enabled on the profile.
- Offset creation can be set at batch level or transaction level.
- The same guide covers delimited ACH imports and wire imports.

What to confirm with your Associated Bank treasury contact
Four values are assigned per customer and only the bank can tell you them: your Company ID (often not just your EIN), the exact immediate origin value they expect in the file header, whether your agreement is set up for balanced or unbalanced files, and your cutoff times and settlement option. Get them in writing before the first upload.
Building the file
Most accounting software, including QuickBooks and Sage 50, cannot export a NACHA file directly. If your system exports one and Associated Bank still rejects it, the validator will usually name the exact line and field. If the reason will not yield, the format setup service works it out with you. This software formats and checks files only. It moves no money; funds move solely through your own bank under your agreement with them.
