Typically, these invoices are made in three sheets, one color copy for the buyer who has paid the payment, one color copy for the sales archive, and one other color copy for the sales department report. This invoice will be a proof of the sale transaction made on credit. In the meantime, you may also need to use the blank invoice on the internet occasionally.
In more detail, the uses of invoices are:
For information goods/services purchased by customers.
For information on the value of the bill and terms of payment to be paid by the customer.
Customer may repair goods/services and/or value purchased if the listed is not in accordance with the order.
Referrals are valid if the goods/services listed will be sold again to other parties.
A legitimate reference to entering transactions into financial books.
Legitimate referrals as tax invoices for certain cases.
Those are the uses of invoices that you should know. Apart from making it easier for you to check out your transactions, it’d be a good thing to let your customers know that you can be trusted when you’re doing your business with them.
