On day one after buying a business, secure every dollar coming in. Transfer bank accounts to your name, update payment processors, change locks on cash locations, and audit autopay settings so tenant and customer payments hit your accounts, not the seller's.

So, let's start with the most important task on day 1. Very thing— very first thing you must do is secure the money. Because if you don't control the cash flow, you don't control the asset. Your absolute priority on day 1 is to make sure every dollar coming in lands in your bank account, not the previous owner's. This means you have to immediately transfer bank accounts and update all payment processing systems. Really, you should have set that up beforehand. Change the locks on any physical cash flow boxes or offices where money is handled. Don't forget to review all autopay settings to ensure the transition is seamless for tenants but secure for you.
