Wave + Annual Company Accounts: Complete Workflow
Preparing for annual company accounts and using Wave? Preparing annual accounts for Companies House requires reconciling a full year of bank transactions. Many small companies still rely on PDF statements from their bank. BankScan AI bridges the gap between your bank's PDF statements and Wave's import feature.

Import for Annual Company Accounts into Wave
After converting your bank statements for annual company accounts:
- In Wave, go to Banking > Connected Accounts > Upload a bank statement (CSV)
- Select the file, map columns to Date, Description, and Amount, then import
Common Import Issues
Wave's free tier has occasional processing delays on large files. Also, Wave uses MM/DD/YYYY by default which conflicts with UK DD/MM/YYYY — select the correct format during import.
