PNC NACHA file requirements
PNC accepts NACHA-format ACH files through PINACLE. The bank calls the feature "ACH module / PINACLE Upload (file pass-through)". Here is what its published documentation requires.
Independent documentation. Not affiliated with or endorsed by PNC.
Before you upload, run the file through the free ACH file validator. It checks the structural rules and PNC's documented quirks in your browser; the file never leaves your computer.
How PNC ACH file upload works
- Next-day cutoffs depend on channel: 10:00 pm ET for direct transmission, 8:00 pm ET for the PINACLE ACH module.
- Same-day cutoffs run 3:00 to 3:45 pm ET and require enrollment.
- PNC warehouses future-dated files up to 45 days.
- Uploads pass control-total validation. Maximum file size is 250 MB.

What to confirm with your PNC 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 PNC 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.
