Choose a CA firm that clearly tells you the pricing for GST, ITR, and MCA form filings so you don’t face surprises later. Make sure they reply quickly, especially during deadlines.

2. For Big Companies & MNCs
Large organizations need CA firms that handle big audits, international work, and specialized advisory services.
Choose a firm with a global network if your business deals with multiple countries. Strong advisory teams are important for mergers, restructuring, and financial planning. Look for firms with industry expertise in banking, IT, pharma, or manufacturing. People usually trust big brands because they regularly handle large corporate clients.
Good Options: Deloitte, PwC, EY, KPMG, BDO.
3. For Investors, VC/PE Firms & High-Growth Startups
Investors and fast-scaling startups need CA firms that are experts in financial checks, valuations, and deal support.
Choose a CA firm that has a strong due diligence team to check a company’s finances, taxes, and risks. They should also know startup valuation, ESOP valuation, and fundraising reports. Make sure they have experience in mergers and acquisitions. Confidentiality and fast delivery of reports are extremely important for investors.
