How do you handle difficult collections for small volume jobs? We have some "network" companies that haven't paid for months. We've sent certified letters, threatened repossession of any materials/items used during service, etc. and still nothing. It's quite frustrating but the volume per job was mostly less than $1000 so paying an attorney or to go to small claims court would quite possibly not be worth it in the end... We've modified our contracts to help us should we run into this with anyone else in the future but these handfuls that have slipped through the cracks in the meantime need to pay us for the work we've done, and we're running out of ideas on how to proceed in a cost effective way.
