    We engaged Mercurius Advisory Services LLC in September of 2023 to prepare our corporate taxes, federal and states. Our due diligence with other firms that had worked with Mercurius revealed positive reviews. Nevertheless, we were apprehensive about the 10-hour difference between Miami and New Delhi. Much to our surprise the time difference actually proved to be a positive for workflows. All communications were smooth and fluid. They promptly prepared the draft returns and answered all our questions and requests. They were able to prepare and file electronically our federal tax returns for our three corporations, and 17 state tax returns. This made it possible, for the first time ever, to file our taxes before the due dates, without the previously needed extensions. Because of the above and their professionalism and excellence, I would not hesitate to recommend their services. We look forward to a continued relationship with the Mercurius team.

    I have worked with the team at Mercurius for the last 4 years and have a wonderful experience. Initially when Ankit reached out to me I was skeptical as I just received news that my auditor was no longer doing PCAOB audits so the timing was great. I called the PCAOB board to check them out as well as reviewed SEC filings made by the company. They are easy to work with very professional.

    Manvi and her team are a very professional and fair pricing firm. I've had a satisfactory experience working with them so far (Mar 13 '24). They have done tax filing and extensions, and now they will help me with bookkeeping. I've recommended them to colleagues, and I encourage everyone in the US, especially solopreneurs, freelancers, and small businesses, to work with Manvi. Her communication and accuracy in her services have been impeccable.

    Mercurius Advisory Services was established in 2008.

    We are based in New Delhi, India. Our 300+ employees currently operate from a single office.
    However, we do have foreign representative offices in:
    ๏‚ท Miami, USA
    ๏‚ท London, UK
    ๏‚ท Tokyo, Japan

    At present, we have a team of over 300 professionals trained in accounting, finance and related
    fields. These include CPAs, ACCAs, CAs and MBAs as well as legal experts. And yes, we can
    certainly provide information on the professional qualifications, experience and other relevant
    details on your assigned expert if you want.

    We usually work as per the Indian business hours and are available from 05:30 AM to 02:30 PM
    We can also structure contracts for specific assignments and processes where work needs to be
    carried out during a time window different from our usual working hours

    As mentioned above, our usual working hours are 05:30 AM to 02:30 PM UTC. This applies to all
    forms of communication โ€” emails, instant messages, phone calls and meetings on various
    online platforms. We try to be more flexible when it comes to pre-scheduled calls and meetings.
    However, we prefer a prior intimation of at least 24 hours in these cases
