Want to accept crypto for my business, how to handle it best?

I sell medium to high value product and would like to offer the possibility for people to use bitcoin or other specific coins like SOL, ETH, … to buy these.

For my business however I want to convert these then immediatly to fiat.

Is there any best practices or is it just receive the crypto, sell it immediately on an exchange and withdraw the fiat from the exchange to my bank account and voila it’s converted?

I’m not new to crypto, I am new to making it functional for real world use/transactions however.

Any advice would be appreciated. I do not accept private messages or chat requests. Please keep the discussion here
