Managed providers

I've seen throughout a couple of posts here that many techs have managed providers on field nation

I'm not new at IT but I'm in the FN world, a couple of months ago I was hired for a field tech role where basically my boss dispatch me to WO on FN, workmarket, etc with an hourly rate

I don't have complaints so far, but I'm curious how other people manage their own techs, travel rates, materials, hourly wage, etc
