Needed to update turnover for a bank loan. They asked for last year's GST return summary, filed it same day, and I had the updated certificate by 11 AM next morning. Loan approved in the same week.

Real update stories
What clients say about our update service.
★★★★★
Changed office to a new city. Address update took only 4 hours — got the updated certificate on WhatsApp same afternoon. Everything on the certificate looks official, same QR code and signature.
★★★★★
My old mobile number was linked and I'd changed it two years ago. Their team told me to update Aadhaar-mobile first, then filed the Udyam update the next day. Clear, honest, no upselling. Would recommend.
Common questions
Everything about the update service.
What fields can be updated on my Udyam certificate?
You can update: mobile number, email address, business address, GSTIN, bank account details, business activities (NIC codes), enterprise type (Micro/Small/Medium), investment and turnover figures, owner or authorised signatory details, and social category.
Any field visible on your existing certificate can be modified. The one thing that stays permanent is your Udyam Registration Number itself.
How long does the update take?
Updates filed before 4 PM IST are usually completed and the revised certificate delivered by the next working day. Complex updates (multiple fields, category change, or NIC code change) may take up to 2 working days.
Once the government portal accepts our submission, certificate generation is automatic and instant. Most delays are in the pre-submission verification step where we double-check data to avoid rejection.
Do I need to visit any office?
No. The entire update process is online. You share your details via our form or WhatsApp, we file the update on the government portal on your behalf, and the revised certificate is emailed to you as a digitally-signed PDF.
Will my Udyam Registration Number change after updating?
No. Your UDYAM Registration Number stays the same for the lifetime of your enterprise. Only the details on the certificate change; the registration number and issue date are permanent.
This is important for bank loans, tender applications, and any place your Udyam number is already on record.
Can I update my mobile if my old number is no longer active?
Yes, provided your new mobile number is linked to your Aadhaar. The government portal sends the OTP to the Aadhaar-linked mobile.
If your Aadhaar is still linked to your old number, you'll need to first update the Aadhaar-mobile linkage via UIDAI (mAadhaar app or Aadhaar Seva Kendra). Once done, we can file the Udyam update immediately.
How much do you charge for updating an Udyam certificate?
Our flat consultancy fee is ₹499 for a single-field or multi-field update filed together. The government portal charges zero fees for updates — our fee is purely for the professional service.
If your update requires prior action (like Aadhaar-mobile linkage correction), we'll notify you before proceeding. There are no hidden charges or additional fees for handling complex cases.
What if the update is rejected by the government portal?
If the rejection is due to an error on our part (typo, wrong document, incorrect data entry), we re-file at no extra cost.
If it's due to Aadhaar-mobile mismatch, PAN-GST mismatch, or other issues on your side, we'll guide you to fix the root cause first. Full refund available under our refund policy if we cannot complete the filing.
Can I update the business activity or NIC code?
Yes. You can add, remove, or change your business activities (NIC codes) on your Udyam certificate.
This is important if your business has diversified or pivoted, as loan eligibility, government subsidies, and tender qualifications often depend on the NIC codes registered. Wrong NIC = missed opportunities.
