Bar inventory
shouldn’t cost
you a thing.
We built the tools we wished existed, tested them in a real restaurant, then gave them to the world. No subscriptions. No vendor lock-in. Just count your bottles and go home.
Every bartender
knows the drill.
Close out. Grab the 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 week.
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 these tools for free. So we did.
Precision instruments for the craft.
Each tool built for a specific job. No bloat. No feature creep. Just what you need behind the bar.
Smart Inventory Sheets
Pre-built spreadsheets that calculate cost, usage, variance, and reorder points. Plug in your counts — the gears do the rest.
Variance Tracker
Compare physical counts against POS sales. See exactly where you're losing money — by category, by bottle, by shift.
AI Bottle Counter
Snap a photo of your shelf. AI reads the bottle levels so you're not eyeballing tenths at 2am with bleary eyes.
Product Database
500+ common bar products pre-loaded. Bottle sizes, costs, standard pours. Skip the data entry, start counting.
Forged on a bar floor,
not in a lab.
Our partner Bill — General Manager of Agave & Rye in downtown Cleveland — opened his restaurant so we could build this the right way. Real bottles. Real counts. Real pressure.
“If you’re going to build inventory tools, you better do it standing behind a bar at 2am with a clipboard. Otherwise you’re just guessing.”
