Quick commerce: avoiding overselling with realtime stock
Mikołaj Lehman
CEO & Founder
Quick commerce delivers in minutes from local hubs where one SKU can sit in many carts, without reservations overselling spikes.
Reservation and cart timeout
Short SKU holds after add-to-cart protect inventory from checkout races.
Timeouts must match UX, prevent “item released” surprises instead of explaining them later.
Geofencing and dispatch
Location affects assortment and delivery fees, we cache zones but invalidate on price or opening-hour changes.
Courier dispatch uses job queues and route limits, not naive first-come ordering.
Mobile and background GPS
Courier React Native apps must respect OS policies for background GPS and battery.
We test weak GPS in city centres, where ETA precision dies.
