When you’re doing business on the road, taking orders and giving receipts for payment, a self-carbonised form is a quick and easy way to get things done. No need for data entry into a computer system, you can write out your order on a self-carbonised paper and it will be copied on the next page.
You might have a busy delivery schedule and quick drop-off situations, there is nothing to worry about. Your delivery person can ask for a signature to be provided on your order, confirming receipt of your goods and payment conditions.
