I currently use regular invoicing software, which has a long turnaround time. Can e-invoicing help me tackle this?

Yes. The e-invoicing platform handles all your accounts. Hence you can use your team’s valuable time for more productive jobs rather than repetitive and time-consuming ones with the platform. And thus increase your productivity.

Does e-invoicing support B2C invoices?

No. It does not support B2C invoices since there is no ITC involved.

What is e-invoicing under GST?

An e-invoice is a Tax Invoice usually issued by every registered taxpayer. Still, it contains some additional information in the form of a QR Code.

Can e-invoicing help me, a tax inspector, spot fraudulent invoices?
