TL;DR
- QBO format is required for QuickBooks Online bank imports with full transaction details
- Manual CSV to QBO requires field mapping, date formatting (MM/DD/YYYY), and account IDs
- Common errors: wrong date format, missing account numbers, incorrect transaction signs
- Zera Books automates PDF → QBO with AI categorization in seconds
QuickBooks Online requires QBO format for bank statement imports because it contains more transaction details than CSV—including account IDs, bank IDs, transaction IDs for duplicate detection, and proper categorization codes. While CSV only imports basic description fields, QBO format imports date, amount, payee, memo, check number, and unique transaction IDs to prevent duplicates.
Converting CSV to QBO manually requires understanding the OFX specification (QBO files use OFX format), mapping each CSV column to the correct QBO field, formatting dates as MM/DD/YYYY with forward slashes (not backslashes), ensuring transaction amounts have correct signs (expenses negative, deposits positive for both bank and credit card accounts), and adding required QBO attributes like Account ID and INTU.BID values.
Understanding QBO File Format Requirements
QBO files are based on the OFX (Open Financial Exchange) specification. Key requirements include:
- Account ID: Unique identifier for each bank account (use same number for same account)
- Bank ID (INTU.BID): Must be from allowed bank label list
- Transaction ID: Unique ID for each transaction to prevent duplicates
- Date Format: MM/DD/YYYY with forward slashes (backward slashes cause import errors)
- Amount Format: Decimal separators only, no currency symbols
- Transaction Signs: Expenses negative (-), deposits/payments positive (+)
| Field | Requirement | Example |
|---|---|---|
| Date | MM/DD/YYYY format | 01/15/2025 |
| Transaction Type | DEBIT or CREDIT | DEBIT |
| Amount | Decimal format, correct sign | -125.50 |
| Payee | Merchant or transaction source | Amazon.com |
| Memo | Transaction description | Office supplies |
| Check Number | Optional for check transactions | 1234 |
| Account ID | Unique account identifier | 123456789 |
| Transaction ID | Unique per transaction | 20250115001 |
