How do high-volume P2P merchants safely receive funds while selling crypto?

I’m planning to start out doing larger volume on Binance P2P and ultimately turn out to be a service provider, so I’ve been making an attempt to know how skilled sellers manage every part safely.

I see some retailers doing 1,000–3,000+ trades in the final 30 days, which is loopy volume. I needed to ask individuals with real experience:

How do you safely obtain funds from so many various consumers every single day?

What sort of financial institution accounts do most merchants use — personal, current, coperate, or a number of accounts?

Is it really helpful to keep separate accounts only for P2P activity?

Are there sure banks, wallets, or cost methods that work better for high-volume buying and selling?

How do merchants scale back dangers like frozen accounts, chargebacks, or suspicious transaction flags?

Any errors newbies make when beginning merchant-level volume?

I’m making an attempt to study the right and safest approach to construction things earlier than scaling up. Would recognize recommendation from skilled P2P merchants.
