What are the mandatory fields in an e-invoice?

Mandatory fields are essential for every invoice and must be included without exception. They form the foundation of a compliant e-invoice, and omitting any of these will result in rejection by the tax authority.

Examples include:

• Invoice number (BT-1)
• Invoice issue date (BT-2)
• Seller's Tax Registration Number (TRN)
• Total amount with tax
