What details should contain in PO.

When creating a Purchase Order (PO), it's crucial to include specific details to ensure clarity and avoid disputes. Key information should cover the supplier's name, address, and GST number, alongside the buyer's GST details. Essential item information includes the rate, quantity, and amount, clearly stating whether tax is included or excluded. Payment terms, conditions, and any interest on delayed payments should also be explicitly mentioned. Finally, a unique PO number, issue date, and authorised signature are vital components.
