Best Banking/Credit Card Solution?

Just started listing a property on Airbnb and it's been a nightmare sorting through my personal bank statements when doing my books.

So far, I've just been putting everything on my Chase Freedom Unlimited/Sapphire Reserve stack, but I'm starting to think it's a bad idea, so what are you all doing?

Did you open a separate business checking account and/or credit card?

Is it a true business account or just a second personal one you use for the property?

How much does it actually help streamline your workflow?

Basically, what's the optimal financial stack for rentals in general (including other expense-tracking/accounting software)?

Thanks in advance!
