i'm aware of Corporation Service Company out of Illinois (CSC) whom files UCC's as a representative. They also charge about $20-25 per, plus state fees.

That is a decently priced service, and they provide a dashboard via the web to put in your data to file.

I also know that some platforms have it built in so that a UCC may be filed through the platform.

My question is, is there any other service that allows the filing of UCC's similar to CSC, that has one centralized interface to file ucc's? - instead of going to each state's secretary of state individually, signing up an account, filing paperwork, paying fees separate, etc.
