Stack at a Glance

Integration Architecture

Google Sheets (master inventory)
  → Google Slides (auto-updated from Sheet)
    → Apache HTML pages (PNG export, 5-min refresh)
      → FireTV + ScreenLite (display)

Square sale
  → Webhook → Google Apps Script
    → Google Sheets (decrement / remove tank designator)
      → Slides update automatically

Key Design Decisions

  • Google Sheets is the master source of truth for inventory — Square is a downstream target, not the source
  • ERPNext rejected — US tax table upkeep burden too high for a small operation
  • ScreenLite ignores meta-refresh — all TV page refreshes must use JavaScript setInterval image src swap, not <meta http-equiv="refresh">
  • Square API access is free — webhook + Apps Script integration has zero incremental cost
  • Livestock deaths tracked via dedicated Sheet tab + Bigcapital journal entries, not through Square
  • Owner draws are not business expenses and must not appear on Schedule C
