The process of electronically creating, sending, and maintaining invoices between buyers and suppliers is known as "e-invoicing." It entails generating invoices in a digital format that is standardized so that parties and tax authorities may share and process them with ease.

Businesses can benefit from e-invoicing in a number of ways, such as less invoice errors, expedited payment processing, better cash flow management, and increased tax compliance. Additionally, it facilitates the billing process and lowers the administrative expenses related to manual invoicing.

An electronic document known as an e-way bill is necessary for the transportation of products valued at more than a specific amount between or between Indian states. It includes information about the kind of products, their worth, the recipient's and supplier's contact information, and the mode of transportation. According to state regulations, e-way bills are required for certain intrastate transactions as well as for the interstate transportation of products valued at more than the allowed level.
