IRN mismatch mostly happens when billing address differs from GSTIN address. Fix that first.

AP team ke liye weekly exception huddle helpful hai — patterns jaldi dikhte hain.

We built a pre-check against the GST portal API before master creation. Cut exceptions a lot.

Have you tried HSN validation at the vendor portal stage? Saved us almost 3 weeks per onboarding.
