Brex is a FREE business checking account that has several benefits, including the ability to earn cash-back reward points on all your spending, whitout actually acquiring any debt, making it a great alternative to reward credit cards.
Now, if you do need a credit line, you'll need to look elsewhere for that, but Brex is still a great online banking service that's specifically designed for business owners.
I also have to disclose that the link below is an affiliate link, so if you do decide to sign up, you and I both get a $250 gift card after you've spent $1000 on your Brex card. Think of it like a debit card on steroids. ;)
