Simply amazing! We are having an amazing experience with Mainstreet. They are exceptional domain experts, provide awesome support and really know what they are doing. We looked at several options but Mainstreet was the obvious choice. They found free money for our start-up and then even advance it at no extra cost. On top of that, you get complete audit protection - it is really a complete no brainer.

It's actually free money I wasn't exactly sure what service they provided at first. After signing up for a 1:1 meeting w/ one of their team members, they explained it really well. This was the easiest sign up process for any tax service I've honestly ever experienced. I'm still trying to wrap my head around the fact that my accountant wasn't collecting these tax credits before...

Refuses a refund & continues to charge, even if they don't deliver I filled out Mainstreet.com's intake form and was told that I qualified for 5 figures in tax credits, for which they charge 10%. Great, I thought. My CPA later said that I don't actually qualify, but Mainstreet refuses to refund their fees and wants to continue charging fees until the "end of the contract". This is unbelievably scummy behavior.

Mainstreet will charge you even if they don't provide services Mainstreet doesn't refund you even if they don't provide their services and hold up to their end of the bargain. This is a scammy business practice -- I'd advise just working with a small business that has sane and customer-centric business practices to get R&D credits filed.

I know nothing about the company nor… I know nothing about the company nor have I ever applied with them. A Brian keep calling me from 8am to 8pm, 7 days a week and 2 to 3 times per hour!! I'm Getting sick and tired of him calling me. I keep blocking the numbers, but he keep calling from another number!! This needs to stop immediately! This is harassment
