Duplicate Transactions
Symptom: Same transaction appears twice after CSV import
Cause: Wave bank connection already imported transaction, then CSV uploaded
Solution: Disconnect bank before CSV import, or delete duplicates manually
Prevention: Choose ONE method: bank connection OR CSV import, not both
Wrong Account Assignment
Symptom: Transactions imported to wrong Wave bank account
Cause: Multiple accounts exist, Wave defaults to last-used account
Solution: Filter by account, bulk-delete wrong imports, re-import to correct account
Prevention: Select correct account in Wave before importing CSV
Date Format Rejected
Symptom: Wave shows "Invalid date" error on CSV import
Cause: Date format not recognized (e.g., DD/MM/YYYY ambiguous)
Solution: Convert all dates to YYYY-MM-DD format before upload
Prevention: Always use ISO date format (YYYY-MM-DD) for Wave imports
Categories Not Matching
Symptom: CSV has category names but Wave doesn't recognize them
Cause: Category names in CSV don't exactly match Wave's category list
Solution: Remove category column, let Wave auto-categorize, then review
Prevention: Export Wave chart of accounts, match category names exactly
