  • No built-in cloud storage integration or synchronisation; cannot extract directly to Dropbox, OneDrive, or Google Drive

  • Web access is not included with a perpetual licence and costs an extra $4.99 per month or $49.99 per year
  • The Pro perpetual licence costs $149.99 against $74.99 for Standard
  • Future major upgrades are a paid discount rather than free for perpetual licence holders
  • The $99.99 per year subscription is the only option that bundles Pro plus web access
