GST invoices
Place of supply decides IGST or CGST and SGST. HSN or SAC, rate and cess come from the item master.

E-way bills
Part A fills from the invoice. Add vehicle number, transporter ID and distance, then generate or extend.
Export invoices
Under LUT or with IGST paid, in foreign currency, with port code, shipping bill number and date.

Questions
Asked about Invoices
01Do I need a separate login for the e-invoice portal?
You add your IRP API user once in settings. After that, Kubertree generates IRN and QR codes for you from the invoice screen.
02Can I make invoices on my phone?
Yes. Invoices, e-way bills and payment links work in the phone browser, and drafts carry over to the computer.
03We are below the e-invoice limit. Is this still useful?
Yes. You make regular GST invoices. When your turnover crosses the limit, switch on e-invoicing and the same screens carry on.
