Does every contractor need e-invoices?
Only GST taxpayers above the e-invoicing turnover threshold notified under GST. Your accountant confirms whether it applies to you.
Does Tatha Vastu decide the GST rate?
No. You set the rate for each work order, as configured for your contract. Tatha Vastu applies it and prints it on the invoice.
Does Tatha Vastu file GST returns?
No. It prepares the invoice and keeps the IRN. Filing returns stays with your accountant.
What if the client disputes the bill after the IRN?
Cancel within the window the portal allows, or issue a credit note, as your accountant advises. Both are recorded against the bill.
