Nationally many countries have their own local market leader. In the Netherlands, iDeal is the most popular (and the most user friendly of those I've tried). http://www.ideal.nl
For moving money internationally and between currencies there is TransferWise, which I personally mainly use for c2c payment but they also support business accounts and I've used it to pay companies on occasion too.
With a TransferWise invite link you can transfer up to £3000 (over $4.5k) for free, here's mine: https://transferwise.com/u/5d78
Where I work we use mangopay, which is specifically for marketplaces. http://www.mangopay.com
