Kolejka kontenerów

One shared view of container deliveries for logistics, warehouses, forwarders and the customs agency, instead of an Excel sheet sent around by e-mail.

Delivery queue grouped by day, with company and warehouse tabs and customs status

Outcome: Replaces a sheet that cost 4 logistics staff about 30 hours a week – about 200 containers a month, 4 companies, every change in the history.

Key decisions

  1. Forwarders work without an account – one-time links instead of logins
  2. Missing documents trigger a warning, not a blocked delivery
  3. Transition period with Excel: the sheet never rolls back changes made in the app
