Bar inventory
shouldn’t cost
you a thing.
A brilliantly built inventory program that lives on your laptop. Voice-walk, count, reconcile, and Process — no AI required. Optional AI only if you want invoice photos read for you. Free. No subscriptions. No vendor lock-in.
The Problem
Every bar manager knows the drill.
End of the calendar month. Grab a barback & clipboard. Count every bottle by tenths. Scribble numbers on paper. Walk to the office. Type it all into a spreadsheet someone made in 2014. Try to reconcile against POS sales. Watch it never add up. Repeat next month.
The bar industry has been doing this for decades. And companies have profited from the pain — selling $3,000 inventory guns, $200/month SaaS platforms, and consulting services that charge by the bottle.
AI changed everything. Now we can build this program for free. So we did.
