How to create an invoice for Businesses and Entrepreneurs in Nigeria

by op-ed contributor

An invoice is a critical component of your business, as it records the transaction between you and your client.

It is a crucial document for business owners to track and measure the sales of goods or services accurately.

In this article, I will guide you on how you can create an invoice for your business.

What is an invoice

An invoice is a document a business or an individual sends to a customer to request payment for goods or services.

It is a formal request for payment that shows the buyer how much they owe for the purchase.

For example, if you purchase five books from an online bookstore for N2,000 each, the store would (if they have created an invoice) send you an invoice for N10,000.

An invoice might include details about the buyer and seller, like your name, the store’s name, and address. It will also include information on the item purchased, the price, and the payment terms.
