Frequently asked questions
Do I need to visit an office in Kolkata for support services?
No. Most of our work is done online. We collect documents by email or WhatsApp, discuss the tender on a call and share drafts for your review. Portal steps that need your login, OTP or Digital Signature Certificate are done by you or in a shared screen session. We never ask for your password or OTP in chat.
Is Bid Nexa part of the eProcurement System of Government of West Bengal?
No. Bid Nexa is an independent advisory firm. We are not affiliated with the eProcurement System of Government of West Bengal, GeM, CPPP or any buyer. We help you prepare and submit on the official portal. The buyer alone evaluates bids and decides awards, so no adviser can promise a result.
How is the fee for support services decided?
Every engagement is scoped first. We look at the tender or goal, the documents you already have and the deadline. We then share the scope and fee in writing before any work begins. There are no hidden charges, and you can decide after the call whether to go ahead.
