I’ve seen their page before and it seems like a good service. They seem to be a convenient way to accept payment via 3rd party api’s via a web plugin, meaning they don’t touch any money and just facilitate the connection. The tax/sales reports and accounting seems nice. I definitely see value in a product like this.

However, I would personally like to avoid middle-men if possible. To me the beauty of accepting BTC as payment is to avoid the traditional rails (banks/merchant processing/etc). I would like to stay as true to that vision as possible but it may not be so easy for lots of people at the moment. Setting up and maintaining a btcpayserver (especially with lightning) is quite the task for a normie.
