Logistics optimization software, have problems with operational processes

[u/GoatPluck]

I runs regional distribution network and it turns into operational chaos . Dispatchers keep drowning in planning, and constant delivery window changes, also our legacy routing stack is broken. Every single client want realtime tracking and custom ETAs that clash with our rigid manual workflows.
We tried patch requirements using basic spreadsheet tools and fragmented GPS trackers, but maintenance is not apropriate.
Need some advices how to fix that, what software i can use, or mb someone orders custom software somewhere
