I need an online wallet where they arent getting in my business, wanting to know where my money comes from, and just leaves me alone. Which wallet? Thanks
Maybe you don't need an online wallet, you are just confused about its concept.
An online wallet is like an email, you can access with a login/password and you could be easily hacked. Additionally, the custodial service may have access to your funds.
That's not what you need, especially to run a business.
If you care about privacy why not make a wallet with Desktop wallets like Electrum or Wasabi for lightweight wallet and Bitcoin core for a full node wallet or make a paper wallet instead.
Or you mean a Payment processor?
The best option for this is Self-hosted like
BTCpayserver I'm using this as another payment gateway to accept bitcoin.
I guess you are right, he needs a payment processor.
https://btcpayserver.org/ is a good option.
