I absolutely don't recommend this service to anyone. Please avoid it by any cost. Use Incfiles or whatever else.
My situation is kinda hilarious. When I was trying to incorporate the company (1 year ago) with Firstbase, I've figured out that Firstbase has been collaborated with Mercury bank, and nationality (my passport) was in there "sanctioned list". Even though, I am the US resident for a long period of time - it does not matter. This is sooooo nice knowing that your ability to start a company with Firstbase and Mercury is based on the "right" nationality and "wrong" nationality! Awesome!!
But I decided to choose another way and maybe make a bank business account via Chase or smth, however, my life situation was changed and I can not incorporate my business anymore with Firstbase.
So I wrote to the customer support of Firstbase and asked for the refund. I needed my 400 USD back, I saved money so hard to have an opportunity to open a business. And guess what? Firstbase has REFUSED giving back MY money, which I even could not use thanks to Mercury bank and their "wrong" nationality policy! Eventually, they have a 7 days period when you can ask for reimbursement while you purchase the service, I absolutely did not know that, there is no information about that, because I would have reimbursed my money immediately!
Firstbase just stole my hard earned money, that's the end of story. I really don't care about Firstbase goofy contracts or whatever rules they made up. There is a fact - my money WAS STOLEN.
Avoid by any cost.
