Built for the way bars actually run service — open tabs, multi-person rounds, cash-discount programs, and the inventory accountability that turns 35% pour cost into 18%.
Disciplined pour cost
Industry typical runs 28–35%; per-bottle yield tracking closes the gap.
Average per-cover bar tab
US bar average — 3 drinks + small food attach over a typical visit.
Beverage share of revenue
Bars are beverage-led; food supplements the bar, not the reverse.
Bar service is a different POS workflow from food service. Katalyst handles open tabs, round splitting, and pre-auth holds the way bartenders actually work.
Hold the card on file when a tab opens. Auto-release at close-out. No more chasing card-walkers at end of night.
Six-top buying rounds? Re-allocate to individual checks at close. Multi-card single-tab support for groups paying piecemeal.
Quick-pick layout, modifier shortcuts, and one-tap repeat-order for the regular who always orders the same thing.
Open tab report, voided check report, comp report, tip-out by bartender — all in one end-of-shift workflow.
Most bars run 28–35% pour cost without realising it. Katalyst's per-bottle yield tracking and pour-variance reporting routinely brings that to 18–22% — directly to the bottom line.
Track theoretical pours per bottle vs actual rings. Variance reporting flags over-pours and unrecorded comps.
Which shift loses money? Which bartender pours heavy? The data is in your POS — Katalyst surfaces it without manual reporting.
If you run a cash-discount surcharge program, Katalyst handles dual-pricing display, surcharge application, and compliance signage automatically.
Drink sales, alcohol-only revenue, and compliance reporting for state liquor authorities — pre-formatted for your jurisdiction.
A bar's contribution margin is set almost entirely by beverage cost discipline. Industry-average pour cost on beer/wine/liquor sits at 28–35%; disciplined bars run 18–22%. On a $1M bar program, that 10-point swing is $100,000 of annual margin — direct to the bottom line. The math doesn't require selling more drinks; it requires selling the drinks you already sell at the cost they should be.
Where pour cost leaks: over-pours (bartenders pouring 1.6oz on a 1.5oz spec), unrecorded comps (the regular who 'gets one on the house' from a bartender, never rung), wrong-bottle pours (rang the well; poured the call), spills, and inventory shrink. None of these are intentional fraud at most operations — they're inattention. The system has to surface them. Per-bottle yield tracking compares theoretical pours-per-bottle to actual rings; variance > 8–10% flags a station or shift that needs attention. That alone, applied consistently, brings most operations from 30% pour cost to 22%.
Card walk-outs are the second margin event a bar POS has to address. A $180 tab walked out is a near-100% loss on labour and inventory already consumed. Pre-authorisation on the card when the tab opens — standard payment-card-industry-compliant tab authorisation — eliminates 90%+ of walk-outs that would otherwise occur. Most bars implementing this for the first time recover 0.5–1.5% of monthly revenue previously lost to walk-outs.
The cash-discount surcharge program is the third lever, and the most operator-dependent. A 3.5–4% surcharge on card payments (with a corresponding 'cash discount' for cash payers) effectively shifts the cost of payment processing to the customer. Bars running this program with the POS automating dual-pricing display and compliance signage see effective processing cost drop from 2.4–2.8% to near-zero. Compliance varies by state — Massachusetts and a handful of others restrict the practice; most states allow it with disclosure. The POS that handles the dual-pricing math, surcharge application, and compliance signage automatically is what makes the program operationally viable at scale.
Concrete examples of how bars operators use Katalyst in the real workflows their concept actually runs on.
8pm–1am: bar runs 35 open tabs at peak, 800+ drinks rung across the night. Each tab pre-authorised at open. End-of-night reconciliation shows 0 walk-outs, $14,200 net revenue, $2,940 in tip-out across 4 bartenders calculated automatically by the system.
Weekly pour-cost report flags station 2 at 31% pour cost vs. 19% house average. Drill-down shows over-pour variance on premium tequila and unrecorded comps on the late-shift bartender. Conversation with the bartender, training reset, system flag for monitoring. Pour cost on station 2 lands at 21% the following week.
Operator rolls out 4% cash-discount surcharge across the bar. POS handles the dual-pricing display automatically; signage at the door and on every menu meets state disclosure requirements. Net processing cost over 6 months drops from 2.7% to 0.4%. On $1.4M annual revenue, recovered margin: $32,200/year.

KPIs tracked
When a tab opens, the system places a hold (typically $50–$100 depending on configuration) on the card. The hold sits on the card throughout the tab; at close, the hold is replaced by the actual charge amount and the difference settles automatically. If a customer walks without paying, the system charges the held amount under the same authorisation. Walk-out incidence drops 90%+ vs. manual cash-handling.
Each bottle has a theoretical pour count (a standard 750ml bottle yields ~17 pours of 1.5oz each). The system tracks actual rings against the bottle's inventory; the difference is variance. Variance > 8–10% per bottle flags either over-pouring, unrecorded comps, or shrink. Applied consistently, bars typically move from 30% pour cost to 18–22% within 60 days.
Yes. Dual-pricing display automatically shows the cash-discounted price and the card-paid price (with surcharge) side-by-side. The surcharge applies automatically at the moment of card payment with no bartender intervention. Compliance signage requirements vary by state; the POS supports the documentation flow the major card-network rules require. Massachusetts has additional restrictions; most other states permit the program with disclosure.
Yes. Drink sales, alcohol-only revenue, and consumption reporting export in formats pre-aligned to the major state liquor authority filing requirements. Some states (Pennsylvania, North Carolina, Utah, others) have additional requirements — the system handles the major ones; check your specific state requirements during onboarding.
