The Limit of Spreadsheets

Why Growing Businesses Upgrade from Excel

Excel is vastly better than Word for billing, but spreadsheet invoicing still carries significant risks:

  • โœ• Accidental Formula Overwrites: Typing an invoice amount over a formula cell silently destroys calculations in future invoices.
  • โœ• No Invoice Number Sequencing: Easy to duplicate invoice numbers accidentally across different clients, violating tax audit rules.
  • โœ• No Live Forex Feeds: Exporters must browse RBI tables manually to locate foreign currency rates.
