Worse Leasing Company EVER!!!

I gave them a one-star because there's no option for zero star. This company is a DISASTER. If I were to turn back the hands of time, I'd rather stay under a bridge and be patient to get leasing through a better leasing company!

Shady Company - Charge for services when not provided

They charge you for services they never provide and refuse to refund your account even if you cancel the service.

We used them for one year to help us with a tax credit. Then cancelled the second year. They still charged us for several months of services even though they did not provide us with any tax documents, guidance or services in any way.

Haven't even moved in yet despite my lease starting today. Roaches in the bathroom. Poop stains in the toilet. Dead bugs all over the floor. Smoke detector needs batteries replaced. When I go to submit maintenance requests it says its already been submitted but it hasn't. 6:45 pm on the day I was supposed to move in a 3rd party contractor contacts me to schedule a cleaning. Don't expect this management company to do anything for you. Worst experience ever.

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.

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.

Ouch… GHOSTED after 5 figure check!

Signed up with them in early 2021 for a tax credit with R&D. I was semi-concerned at first but they assured me this was 100% good to do and it was “free money.”

I wrote them a check for figures and we had a couple of follow up calls for them to “gather more details.”

After the end of 2021 every time I’ve reached out about needing what they said they were going to deliver for my return they never responded. I’ve been super persistent and emailed Robert probably 10x following up.

They’ve officially ghosted me and didn’t even say, “sorry we actually can’t help you despite qualifying you.” No refund, no communication.

Feels like I got scammed. Hope to hear back for my company pompa program. I will update this review if I ever hear back (if possible.)

Jury is still out if this is a scam.

I signed up for Mainstreet in Dec 2021. Filled everything out, and was told by the sales guy John, that we would get the money at the end of January. The deal is we get a good size check but we pay them a couple grand each month for the rest of the year, so John said we would only be underwater for 1 month, which sounds fine...or so I thought. But then comes reality, January goes by and they say end of Q1, then Q1 goes by and they say Q2. I keep paying them each month and they keep moving the goal post on when we will actually get any money. My biggest frustration is they had this "cash advance" option when we were considering signing up. But we didn't do it because John said it would only be "4-6 weeks from the beginning of the year" until we get a check. So once it reached April (we've paid them almost 5 figures at this point) and no money I said, okay let's do the cash advance because your estimates were clearly way off. And...of course they say "sorry the cash advance is no longer an option because our estimates were right at the time." Wait what? NO that's not how that works. Your estimates were January and it's April. You can't just change your estimates when they turn out to be wrong and say they were right at the time. That's not how estimates work. (The market will go up!...it goes down...oh well our estimates were right at the time). So in the end, we're still waiting on what we were promised with this service. I think there are others out there that are cheaper and more reasonable. So at this moment I would suggest taking your money and going elsewhere. I'm hoping all works out at some point and if things do (ie if this isn't a scam) I will update this post. If you're reading this post and it is not updated, then that means nothing has changed and we got bamboozled out of our money. So at this moment I'm just still hoping this wasn't just a big scam. We'll see I guess.

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.

Do you love free money?

Do you love free money? That's what Mainstreet does. They're constantly releasing new features which as an early stage business means a lot - the more operating cash we have to do our business, the better we grow.

The team have great experience, really stood out in the pack and have awesome support.

Quick sign up, easy experience, amazing customer support

I was encouraged to apply through other founders and they were absolutely right. It took me no more than 3 minutes to sign up, integrate with my payroll system, and receive notice that we were to receive the R&D tax credit. The team was incredibly responsive with follow up questions, addressing my concerns re: audit and financials, and giving us cash now vs. a year later. Looked at other companies and no other ones provided such a level of responsiveness and immediate payment.

An amazing product for founders

Our company started using MainStreet in August and it's been trajectory changing for us. Took 20 minutes for us to qualify, and receiving the advances monthly is game changing and allows us to better plan out our runway. Highly recommend!

Mainstreet saved our company

Mainstreet saved our company. In the middle of the pandemic they were able to give us back 6 months of runway that we otherwise would have never had, and saved 18 jobs. They are the best service I've ever used.

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...
