Delivery challan Tax invoice

This discussion clarifies the requirements for e-way bills and tax invoices when goods are initially sent via delivery challan. If the initial delivery challan didn't require an e-way bill (due to value or location), and a subsequent purchase order pushes the total value over £50,000, an e-way bill is generally not needed for the original movement of goods. Instead, a standard tax invoice should be issued, referencing the original delivery challan numbers.
