Two more things to offer the same client.
Once a client has a building on your platform, the next conversations are easy. Both are InSight modules, and both live in the account the client already has.

InSight BLE
The equipment in the yard.
Trailers, generators, compressors and implements seldom get a tracker of their own. With InSight BLE each carries a Teltonika EYE beacon, and the tracker in whichever vehicle tows it reports where it is.
Your client sees which vehicle has each item, where each was left and for how long, and is told when something is left behind or is not back when it should be.
- No SIM card or wiring on the equipment
- Works with the Teltonika trackers already in the vehicles
- A register with licences and services

For stock, tools and returnable containers handled item by item, InSight RFID reads labels at doors and docks, with handheld scanners and with readers on vehicles.
Every read is kept as evidence of where and when an item was seen, and anything unexpected becomes an exception for a person to review. It is in its final testing now.
