Erwin-Violet-Hummingbird Hi Erwin,
That's it a good question. And the answer is simple. There a three scenarios for business use:
A bunq.me url is linked to a bunq Personal => You can't use it for commercial use. This is stated in de T&C of bunq Personal
A bunq.me url is linked to a bunq Business => Yes! You can use bunq.me for business use!
A bunq.me url is linked to a non bunq account => No, you may not use bunq.me for business use! This is stated in the T&C for non bunq users.
Hope this clears things up! Have a great day 👍🏼
