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.
