Billing is an important undertaking for any business. It’s how companies get paid for the work they do on behalf of their customers and clients. But it’s not always a straightforward or even simple process. 

An invoice is a document that details the nature and the cost of a service provided. This document tells the purchaser what, when, and how much to pay for a service.

A typical invoice should include a business name, date, descripttion of services, unique invoice number, and payment method. An invoice may also include payment terms that can stipulate things like a 30 day payment period and late fee.

It is important for the document to have an accurate date, invoice number, and descripttion before they are passed on to the client. Errors in an invoice may sometimes result in late payment, which can be a pain point for contractors, freelancers, and consultants.
