Straightforward Support Without the Sales Pitch
We heard about Mainstreet through Joinsecret and got $500 in credits there, which was appreciated, but what kept us on the platform was the straightforward support and the way they handled follow-up questions without turning every reply into a sales pitch

Streamlined R&D Tax Credit Questionnaire
Mainstreet made the R&D tax credit process much less painful for our small team, especially the questionnaire flow that pulls the right details out of engineering and finance without a lot of back and forth

Fast Eligibility Review with Joinsecret Bonus
We found Mainstreet through Joinsecret and ended up with an extra $500 in credits, which was a nice bonus, but the real value was how quickly they reviewed our eligibility and explained what was worth pursuing and what was not

Organized Tax Credit Workflow with Joinsecret Credits
I came in mostly for the tax credit help, but the $500 in credits we got via Joinsecret was genuinely useful since we were already comparing tools, and Mainstreet itself was organized enough that our finance lead actually enjoyed using it

Plain-Language Steps and Deadline Reminders
What stood out to me was how Mainstreet translated fairly technical tax incentive rules into plain steps our ops team could actually follow, and the reminders kept us from missing deadlines we probably would have overlooked

Smooth Setup with Payroll and Finance Integrations
Setup was smoother than I expected, and the integration points for payroll and financial data cut down on manual uploads a lot, though I still had to double-check a few figures on our side before submitting

Focused, Credible Credit Recommendations
I appreciated that Mainstreet did not push every possible program at us and instead focused on the credits that matched our payroll and R&D activity, which made the whole process feel grounded and credible

Early Savings Estimate for Lean Teams
Mainstreet was helpful for a lean startup because it gave us a fairly clear estimate of potential savings early on, then backed it up with a process that did not eat up weeks of internal time

Guided ERC Documentation Support
The platform saved us time on the ERC side because the document request list was clear and the team was responsive when payroll reports needed clarification, so it felt more like a guided process than a paperwork dump

Transparent Filing Status Dashboard
We used Mainstreet to handle both tax credits and bookkeeping-related cleanup, and I liked that the dashboard showed where each filing stood instead of leaving us guessing what was happening behind the scenes
