What this channel cannot do Important
GST Bill Maker, a product of Tanvi Fintech Private Limited, publishes free compliance tools and general invoicing guidance. We do not provide tailored tax advice, file returns on your behalf, take a view on transactions specific to your facts and circumstances, or represent you before the GST authorities.
For those matters, please engage a Chartered Accountant or tax professional in your jurisdiction. For a general discussion on invoice format compliance — what fields are mandatory, when CGST applies versus IGST, how to handle export invoices under LUT — we are happy to point you to the relevant statutory provision so you can take the conversation forward with your own advisor.
