Trust & Safety
How verification works
Every supplier goes through the same three checks, in order, before they can list
1
GST & business check
We validate the supplier's GSTIN against government records and confirm the business is registered and active.
2
Certificate review
Quality certificates, factory licenses, and material test certificates are reviewed before they're marked verified.
3
Live on marketplace
Once verified, the supplier's trust score and response rate stay visible and update with every enquiry they handle.
