The service was easy to use and all of our documents were received in a timely manner. Nothing I can think of at this time! There are no downsides for me so far with their service. So far we have been very satisfied with the level of customer support they offer as well. It's a great service for small businesses looking for an affordable way to handle filing requirements. We used them when starting up our business and now we've expanded into payroll processing. They make it simple, quick and inexpensive for us to comply with regulations like e-signatures or having legal advice reviewed by others before signing important agreements.
