Simplify your purchase cycle post E-invoicing: PART B

Once E-invoicing becomes applicable to all registered users, it will become an uphill task to keep a track of all E-invoices generated and shared. Further, the schema being new, the suppliers would also be grappling with it.
In such a situation automation and technology are the only rescues of both supplier and the buyer. It is not debatable that it is the responsibility of the supplier to raise E-invoice within the stipulated timeline and share the same with the buyer. However, it is the buyer’s ITC that remains at stake. Therefore, E-invoicing remains equally important for the buyer.

Under the backward integration approach, the purchaser can choose to import E-invoices generated by its suppliers from the ERP system.
