Inventory Management

Source of Truth

Google Sheets is the master inventory. Square is a downstream target. Never update Square first and then try to sync back to Sheets — always update Sheets first.

Google Sheets Structure

Column Field Notes
A SKU Unique identifier
B Display name Name shown on price board
C Price Retail price
D Tank designator(s) Space-separated: T4 T5. Drives which TV slide shows the item. Remove when sold.

A separate tab tracks livestock deaths — used for inventory shrinkage journal entries in Bigcapital. See Accounting.

Square POS Integration

Current State (Manual)

New inventory added to Square via CSV catalog upload. Sales are recorded in Square, then manually reconciled against Google Sheets.

Planned Automation

Direction Method Status
Sale → Sheet Square webhook → Google Apps Script → remove tank designator Designed, not deployed
Sheet → Square "Push to Square" Apps Script button Planned, not built

Square API Notes

  • Square API access is free — no additional cost beyond transaction fees
  • Webhook + Apps Script integration has zero incremental cost
  • Apps Script is deployed as a Google Web App to receive Square webhook POSTs

Adding New Livestock

  1. Add row to Google Sheet: SKU, display name, price, tank designator
  2. Slides auto-update → TV price board updates within 5 minutes
  3. Push to Square: CSV upload to Square catalog (manual until automation is live)

When Item Sells

With automation (planned): Square fires webhook → Apps Script removes tank designator → done

Manual fallback (current):

  1. Process sale in Square
  2. Open Google Sheet
  3. Remove tank designator from col D for that item
  4. Slides auto-update, TV picks up within 5 minutes

Livestock Death Tracking

  1. Record death in dedicated Google Sheet tab (date, species, SKU, cost)
  2. Enter as inventory shrinkage journal entry in Bigcapital
  3. Do NOT process through Square
