Sims owning a small business unable to pay bills

Same thing here. Was going to try removing my mods and adding them back in slowly to find the culprit, but I'm assuming you already did that. My Sims tried paying bills every possible way (mailbox, phone and computer) and they go through the animation, but the money never gets deducted and the bills aren't paid. Eventually the repo person showed up. Mine also have lost electricity and water, and cannot open the business without them. The game is unplayable.
