Who must e-invoice

A business whose aggregate turnover crossed ₹5 crore in any financial year since 2017-18 must generate e-invoices for B2B supplies, exports and credit and debit notes. Some sectors, such as banks and insurers, are exempt.

How it works

  • Your billing software sends the invoice details to the Invoice Registration Portal.
  • The portal returns an IRN and a signed QR code, which go on the invoice.
  • The details flow to your GST returns and the e-way bill, so there is less re-typing.
  • Businesses with turnover of ₹10 crore or more must report each invoice within 30 days of its date.

Do it in USR One. USR HRMS runs leave and attendance, and USR Payroll (add-on, India, by invitation) handles PF, ESI, PT, LWF and TDS on salary on the same employee record. Payroll software · USR HRMS
