What Clients Say About Us
The team did an outstanding job with month-end close! They ensured the financials were delivered on time and with great accuracy. Their dedication and attention to detail is appreciated. I especially want to highlight how well they managed one-off email requests and last-minute changes - truly a testament to their professionalism and flexibility. Keep up the excellent work!
I've been really impressed with Windy Street's work. The team learns quickly and avoids wasting time by waiting for clear, finalized information before moving ahead, this has saved us from a lot of unnecessary reworks. Initially, I was concerned about delays from frequent changes on our end, but Windy Street has handled these smoothly and efficiently. They're great communicators and have a talent for simplifying complex CBV concepts.
We have been very happy with the relationship with Windy Street and the continued development of the team and improved collaboration. Looking forward to building the relationship in future years!
Considering the complexity of the client setup and the fact that we were working with a consolidated C-Corp in GoSystems, there was certainly a lot that could have gone wrong. But our team stayed focused, navigated the challenges effectively, and kept the project moving forward. In the end, we delivered a strong, high-quality work product that we’re really proud to have put in front of the client.
Just wanted to pass along some excellent feedback on Team’s work on a recent insurance brokerage project. Windy Team was able to attend the diligence calls and, in some cases, I was able to record follow-up meetings that were tricky from a timezone perspective. Windy Team did all the work, including with very limited guidance after the calls, Windy Team was able to quantify and document most of the adjustments with limited review/follow-up from me. Great teamwork and an excellent success story – hoping to be able to continue this success going forward.

Frequently Asked
Questions
Do you offer a pilot or demo engagement before full onboarding?
Yes, we offer pilot engagements that allow CPA firms and deal teams to evaluate our offshore financial due diligence capabilities before committing to full-scale onboarding. The scope and duration of the pilot depend on the nature of the FDD work, the complexity of the engagement, and team availability. Most pilot engagements cover a defined deliverable, such as a quality of earnings (QoE) analysis or working capital review, so you can assess output quality firsthand.
Can we scale the team quickly during high-deal volume periods?
Yes. We understand that deal flow is rarely predictable, and your offshore FDD team needs to move with the market. We maintain a dedicated pool of experienced deal professionals specializing in financial due diligence, valuations, and financial modeling who are not assigned to any specific client. During peak deal periods, we can rapidly expand your team by drawing from this on-demand resource pool. If you have specific scaling requirements, we are happy to walk you through how we structure that.
Can you assist with due diligence and financial modelling for acquisitions?
Absolutely. Our transaction advisory team includes over 50 professionals specializing in financial due diligence (FDD), valuations, and financial modeling. More than 90% of our team members hold Big-4 backgrounds, with an average of five or more years of experience supporting US market transactions. We provide end-to-end buy-side and sell-side financial due diligence and modeling support, delivered from India on US-aligned timelines.
How long does it take to hire and onboard new team members?
The typical onboarding timeline for a dedicated offshore FDD team ranges from one to three months. This is primarily due to standard notice period requirements in India, where most professionals are contractually obligated to serve up to 90 days with their current employer before transitioning to a new role.
We manage this proactively by maintaining a strong talent pipeline and identifying qualified FDD professionals in advance wherever possible, so your engagement is not delayed.
How do you ensure quality control and review of client deliverables?
Our quality control process differs by engagement model.
Under the dedicated team model, we recommend structuring your offshore FDD team with a clearly defined hierarchical framework. This ensures all work products go through multiple levels of internal review before being delivered to your US team.
Under the on-demand model, all deliverables are reviewed by senior-level professionals with deep subject matter expertise in financial due diligence before anything reaches the client.
