PourWatch: Bar Inventory Variance & Shrinkage Alerts

PourWatch: Bar Inventory Variance & Shrinkage Alerts ships as a ready-to-import n8n automation package: load the bundled workflow JSON, connect the credentials listed on this page, and activate it on self-hosted n8n or n8n Cloud.

Turn your weekly bottle count into a dollar figure — PourWatch reconciles counts against deliveries and POS sales, then emails exactly which pours went missing and what to reorder.

Turn every weekly count into a variance number: opening stock plus deliveries minus closing, against what the POS actually sold
Flag only the bottles that matter, using both a percentage threshold and a minimum-units floor so slow movers never cry wolf
Price the gap twice — what the missing stock cost you and what it would have rung up at menu price
Get an AI-written likely cause and a concrete next action for every flagged item, grounded in your own numbers
Receive a suggested reorder list sized to your real run rate before a fast mover runs dry mid-shift
Chart shrinkage week over week from a Trends tab the workflow fills in automatically
Run it all on the Google Sheet your weekly count form already writes to — no $99-a-month inventory platform

How it works

Workflow summary

One workflow handles everything end-to-end.

1Checks every morning whether a new weekly count has landed on your count sheet
2Reconciles the period between the last two counts: opening stock plus deliveries minus closing stock
3Compares that against what your POS actually sold, converting pours into bottles
4Flags every item whose variance breaks your threshold and prices the missing stock at cost and at menu price
5AI explains the likely cause of each flagged item and suggests what to order before you run out
6Emails the costed variance report, then appends every item to a Trends tab so you can chart shrinkage week over week

FAQ

About this template

How long does it take to set up PourWatch: Bar Inventory Variance & Shrinkage Alerts?

Most people finish in minutes following the guide. If you’ve never used n8n before, budget an hour — the first workflow is always the slowest.

What if I get stuck?

Email support@n8ntemplatestore.com. Free basic support is included with every purchase, and you’ll get a reply from our team within 24 hours. If setup needs more than email, we can schedule a call.

Do I need to pay for Google Sheets?

API costs are separate and go directly to the provider — typically a few dollars a month at most for a solo business. Full breakdown is in the setup guide.

Can I customize the workflow?

Yes, completely. You own the .json — edit nodes, swap in your own prompts, re-wire the logic. Our support team can help you plan customizations over email.

What if it doesn’t work for me?

Refunds are issued only as described in our Refund Policy (https://n8ntemplatestore.com/refund-policy). Or add Setup Service at checkout for a live install and test session — pick any tier you prefer.
