I worked for a startup where we had to take credit card payments.<p>The first bank we dealt with let us sign up for a merchant account, even knowing the kind of business we were in would require &#x27;cashing out&#x27; winnings, without batting an eye.<p>Then in the first weekend with our shiny new merchant account [1] we racked up 5 figures in sales and they froze the account. They said they suspected fraud. It was an insane hassle to get people their money back.<p>I assume the guy got a commission for signing us up; no loss to him if the merchant account didn&#x27;t actually work for us.  ¯\_(ツ)_&#x2F;¯<p>Later on we found another way to pay people out, and signed up with a better merchant account that has redundancy,[2] i.e. it is backed by two merchant accounts behind the scenes, so we can switch to another one if one of them get&#x27;s &#x27;upset.&#x27;<p>Credit card merchant accounts can be shut down on you for any reason at any time, we&#x27;ve learned, leaving a complicated mess to sort out.<p>[1][2] After a considerable amount of development work to integrate with their API.
