GST e-invoicing

GST e-invoicing software for your businesses

Currently, e-invoices generated by different businesses lack a standard. They use the format as provided by the ERP or billing software. Lack of a standard format leads to a scenario where e-invoice generated on one billing software can’t be read by another, requiring manual data entry from an electronically generated invoice.

ROSTAN GST e-invoicing application will ensure complete interoperability of e-invoices across the entire GST eco-system and will eliminate the need for manual data entry mitigating chances of errors
