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

FAQ: Wave Accounting Imports
Is Wave's free tier really unlimited for bank transactions?
Yes, Wave's free tier supports unlimited transactions, unlimited CSV imports, and unlimited bank connections (if your bank is supported). The paid plans ($16-20/month) add receipt auto-matching, advanced categorization AI, and faster support. For most small businesses, free tier + external converter is the best value.
How do I match receipts to imported transactions?
After CSV import, use Wave's mobile app to scan receipts. Free tier requires manual matching (click transaction → attach receipt). Paid plans auto-match by amount and date. Keep receipts for IRS requirements - business meals, travel, and purchases over $75 require documentation.
Can I import multiple bank accounts at once?
Wave requires importing to one account at a time. With our bulk converter, process all statements (checking, savings, credit cards) simultaneously, then upload each CSV to its corresponding Wave account. Takes 5-10 minutes for all accounts vs 3-6 hours manual entry.
What if my bank isn't supported by Wave's bank connection?
Wave supports ~12,000 banks in US/Canada only. For international banks, regional credit unions, or unsupported institutions, PDF-to-CSV conversion is the only option. This actually works better - you get full historical data (Wave connections are limited to 90 days) and complete control over categorization.
Should I upgrade to Wave's paid plan or use an external converter?
For most small businesses: Wave Free + External Converter ($49/month) beats Wave Paid ($16-20/month). External converter gives perfect CSV format, bulk processing, and works with ANY bank worldwide. Wave Paid only adds receipt auto-matching (manual takes 5 extra minutes/month). Save money, get more features.
