We all know as WordPress developers, when launching a website you need to develop on a testing area, copy it to the live hosting and then optimise for deployment.
You then need to setup a staging area for testing updates, and also put a plan in place to keep up with plugin, theme and core updates. This is all whilst making sure the site is performing well.
Managing Domain names
can be a pain, and often DNS records are spread across different providers.
This all needs to be done before new paying work can be received from the client, and if there is ever any issue, you're at fault if their site is not working correctly, sometimes causing clients to hold their payment at ransom until it's fixed.
