Couple finances: one freelancer, one salaried employee
She gets paid on the 28th of every month. Always the same amount, give or take. He invoices when he gets paid, which is sometimes the 5th, sometimes the 20th, and sometimes not even that month. She knows exactly how much she’ll earn in July. He has no idea how much will come in over the next three weeks.
If this sounds familiar, you’re not alone. It’s one of the most common household setups, and if you don’t design a financial system that absorbs that asymmetry, the asymmetry turns into arguments.
