What it checks
Before you import
Is the OFX structure valid?
Confirms the file has the required header, <OFX> envelope, sign-on block and transaction list QuickBooks expects.
Are transaction IDs unique?
Duplicate FITIDs are the #1 reason QuickBooks silently skips rows. We count them so you catch it before importing.
Will QuickBooks recognize it?
We check for the Intuit bank tag (INTU.BID) that .QBO and .QFX files need. Generic .OFX files won't have it, that's expected.
