How does a WIP account work and If I want to incur expenses and revenue in the same month is WIP suppose to incur these for me automatically? Should I change invoice dates to match billing dates?

What is WIP? A software porgram I am thinking...

It is a holding account used in some softwares I think..

Typically WIP stands for Work In Progress, referring to a type of inventory.

What are you trying to accomplish here… I am still not quite following the question. Sorry
