What CSV format does Wave Accounting require for bank imports?

Wave requires YYYY-MM-DD (ISO format) dates, a Description column, and an Amount column with negative values for expenses and positive for income. EasyBankConvert automatically formats your bank statement PDF into Wave's exact CSV specification.

Can I import bank statements to Wave Accounting for free?

Yes, Wave's free tier supports unlimited CSV imports and unlimited transactions. You can import as many bank statement CSVs as needed without any charge from Wave. Pairing Wave Free with EasyBankConvert gives you a complete accounting solution at minimal cost.

How do I match receipts to imported transactions in Wave?

After importing your CSV, use Wave's mobile app to photograph receipts. On the free tier, you manually match each receipt to its transaction by amount and date. Wave's paid plan adds auto-matching, but manual matching only takes about 5 extra minutes per month for most small businesses.

Does Wave support importing bank statements from international banks?

Wave's built-in bank connection only supports about 12,000 banks in the US and Canada. For international banks, credit unions, or unsupported institutions, converting your PDF statement to CSV with EasyBankConvert is the only way to get transactions into Wave.

How do I avoid duplicate transactions when using Wave CSV import?

Use only one import method per account: either Wave's bank connection or CSV import, never both for the same period. If you switch methods, disconnect the bank feed first. Wave does not have built-in duplicate detection, so overlapping imports will create double entries.

Can a bookkeeper use Wave with CSV imports for multiple clients?

Yes. Bookkeepers can manage separate Wave organizations for each client and import converted CSVs individually. EasyBankConvert's bulk processing lets you convert statements for all clients at once, then upload each file to the correct Wave account. This workflow saves bookkeepers with 5 clients over 230 hours per year.

Common Import Errors & Solutions

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
