Building a custom IoT logistics infrastructure is a massive undertaking, so partnering with an experienced development team is wise. I'd recommend checking out Limestone Digital's logistics software development. They've built end-to-end solutions for other companies needing large scale monitoring, tracking, and automation across complex distribution networks.

We actually worked with them a few years back when expanding our own fleet and warehouses. We wanted real-time visibility into inventory flows plus the ability to adjust routes and loading algorithms on the fly. But didn't have the software capacity to build this natively. Limestone created a custom platform tying together all our backend systems, sensors, mobile devices. It gave us a centralized logistics command center that improved efficiency over 30% the first year. Their devs were up to speed quickly and able to turn abstract concepts into concrete solutions. So I'd encourage you to reach out to them to discuss your vision!
