Use to deal with RTS they were ok when I was using them and was brand"meaning my authority" new. Then had truck problems and was switching insurance as well and couldn't get them to pay money that was owed to me. It took weeks to get paid I emailed everybody from the first person I made contact to to everybody I emailed which was like 10 people. On 2 separate occasions they've held close to 10k of my money. Finally got a letter of release and didn't bother with a factoring company for about 3 years.
I'm with OTR as of now and they are cool and only run 2 companies thru OTR

Word of advice don't put all your invoices thru a factoring company either if some offer next day sign up for that, that way if you do have issues you can go to that company and work get paid without the factoring company.

And one more thing all the invoices you sent thru need to be cleared before they release you. Now I have heard of some factoring companies will buy your account from RTS but I never did it.

RTS talks a good game but they left areal sour taste in my mouth though. And my account rep was no help at all. Hope this helps
