Delivery note inter state

For interstate sales of materials, a delivery note alone is generally not sufficient if the value exceeds £50,000; a tax invoice is typically required. However, a delivery challan is a valid document for goods sent for job work, even for interstate movement. If your transaction involves both material supply and installation services, it's considered a material supply requiring an invoice. For job work, an e-way bill is necessary even for low-value interstate movements when using a delivery note or challan.
