## 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
