When should I send my developer invoice?

Software developers complete many different types of projects. These range from large website builds and mobile app development to ongoing website maintenance. Many of these projects are built from scratch—which are often more costly.

Deciding how to charge depends on the project work because not all development work is the same. While some clients are looking for an eCommerce website built from scratch, others may just need a simple website with a few pages. Understanding the difference and choosing how you want to charge is the first step before you decide to include it on your terms on your developer invoice.
