Two apps,
one operator
stack.

Açsan Gelsin lets independent restaurants run their own delivery operation without the marketplace fees — a dispatch app for the kitchen and a route-optimised courier app for the rider, paired in real-time.

/01   THE BRIEF

Mid-size restaurants in Türkiye were paying marketplace tax — up to 30% per order — to platforms that own the customer. Açsan Gelsin was launched to give that operator stack back, white-label.

We built two apps in parallel — Açsan Restaurant and Açsan Courier — sharing a single dispatch backend with real-time tracking, route optimisation, weekly payouts, and cash-on-delivery reconciliation.

Apps shipped 2 Restaurant + Courier, iOS + Android each.
Real-time <300ms Dispatch event → courier app.
Routing Maps SDK Smart route optimisation per assignment.
Payments Cash + Card Per-courier cash reconciliation built in.

/02   THE APPROACH

The hard part is not the order — it's the cash, the chargeback, the rider running late. We modelled those failure modes first and built the happy path around them.

Restaurants subscribe; couriers join their network. Orders flow from POS → restaurant app → dispatch → courier app → customer, with push notifications, ETAs, and post-delivery review on every step. Restaurant accounting and rider weekly statements close the loop.

"

We finally own our customer relationship again — at a quarter of what the marketplace was charging.
