<prompt> Human: I work on salary, everything is very straightforward when it comes to budgeting. Recently, I gained more insight in to my fiancees income and we have been working to manage it together. It is confusing me!She is self-employed and gets CC transactions deposited 3 days after the service. We save all cash, and all checks are deposited to the same place as the CC transactions business account. When budgeting, I am realizing her income is super variable. Pre-tax range is from 3500 to 6000, so we have had trouble planning on paying off debt etc. Are there any best practices for working with this kind of situation?  <response>: You have to mentally separate the business account and your personal accounts.Treat the business account like payroll. Pay yourself a sustainable periodic wage from that account. Budget based on that wage draw. Make sure you have set aside proper withholdings for taxes.
