Sales on approval basis

This discussion clarifies the process for sales on an approval basis. You can deliver goods using a delivery challan, even if an e-way bill is required for high-value items. The delivery challan is valid, and you have up to six months to issue a formal tax invoice. Importantly, you don't need to generate a new e-way bill when you issue the final invoice; simply reference the original delivery challan and e-way bill numbers.
