The problem with other tools

  • Tax returns contain SSNs, bank accounts, and income data — too sensitive for server uploads
  • Month-end means merging 50+ invoices — batch processing is essential
  • Clients trust you with their most sensitive financial data
  • GDPR and data protection regulations apply to financial document processing
