ShiftVoice OS is an end‑to‑end drive‑thru voice agent for QSR franchise groups (20–300 locations) that plugs directly into existing POS and headsets. Franchise operators struggle with chronic understaffing, slow lanes, and missed upsell scripts, while current AI pilots from giants (McD, Wendy’s) are closed ecosystems and inaccessible to mid‑market brands. ShiftVoice routes every order through a noise‑robust, menu‑aware agent that handles 80–90% of interactions and gracefully escalates to staff on edge cases. - Franchise‑grade integrations: certified connectors for Revel, Toast, Brink, Xenial, NCR used by QSRs, not just indie POS. - Menu‑tuned NLU trained per brand (combos, LTOs, regional items) with live sync from POS pricing. - Lane optimization: real‑time queue estimates, dual‑lane balancing, and “fast order” prompts based on historical patterns. - Upsell engine: A/B‑tested scripts per daypart; tracks incremental revenue per lane, per store. - Franchise analytics: compare AI vs human order time, accuracy, and upsell by location and shift in one console. This is defensible via brand‑specific training data, integrations, and lane performance benchmarks that compound over time.
