Hello,
If you see the 'Crypto Rules' Image shared at this answer , the second point is about getting a hardware wallet.
For business purposes I would recommend a cold storage wallet, and there are many which have established a name in the market by now. Paper wallets are fine too but they do not provide the added security which a hardware wallet would give.

Why a Hardware Wallet
Well, because its secure as its offline and the only real way of keeping your "private keys" secure ..
Hope it helps
