Integration can be loosely defined as the process of allowing two or more systems to be brought together so that they behave as one. In essence allowing an update to be made in your accounting system (to price or product descriptions) and to have these changes reflected on your website (or vice versa), and potentially on any number of associated systems.
"The team at Kodaweb were exceptional. They listened to what we needed and were very responsive throughout the development process integrating our additional needs seamlessly as the project progressed. We are delighted that we chose Kodaweb to design our new school website."
