Hello eveyone.

Need guidance from GST experts

A customer has recently informed us that he is GST-registered and has requested us to amend all his invoices for FY 2025–26 from B2C to B2B.

There are approximately 200 invoices to be amended, spread across multiple months. As per the current process on the GST portal, we need to reduce the corresponding B2C sales month-wise and report each invoice separately under B2B, with the applicable GST rates.

This process is extremely cumbersome, time-consuming, and lengthy, considering the number of invoices involved.

Is there any provision to make these amendments in bulk on the GST portal, or is there any alternative, simpler method to complete this process?

Requesting GST experts and experienced professionals to kindly guide us on the correct procedure and any practical solutions.

Thank you in advance!
