Union POS

Best for: High-volume bars, nightclubs, music venues, fast-casual

iPad-based restaurant and bar POS built around speed at the counter. Supports 1,000+ open tabs without lag (the use case that breaks most POS systems on a Saturday night). Customer-facing app lets guests order and pay from their phone, which moves bar lines faster and lifts average ticket. Offline mode keeps transactions running through internet outages with one-button tab close at end of night. AI-driven reporting and 24/7 support layered on top.
