About Intuit Interchange Format (.iif)

IIF (Intuit Interchange Format) is QuickBooks Desktop's tab-delimited batch format. Unlike QBO, IIF lets you import full journal entries, chart-of-accounts mappings, and split transactions in one file. Our converter maps every parsed transaction to the correct account, respects your CoA, and emits an IIF that passes QuickBooks' strict header validation.

Why bookkeepers pick BankToBooks for IIF

Every transaction validated — dates, amounts, running balance reconciled before export.
Category auto-tagging so IIF imports arrive pre-coded, not stuck in Uncategorized.
Multi-page and scanned PDFs handled with OCR — no need to re-key anything.
Zero setup: no bank IDs, no direct-connect fees, no waiting on Intuit approvals.

FAQs

IIF vs QBO — when should I use IIF?

Use IIF when you need to import full journal entries, splits, or CoA mappings. Use QBO for straight bank feeds.

Does IIF work with QuickBooks Online?

No. IIF is QuickBooks Desktop only. For QuickBooks Online, export to QBO or CSV.
