A reservation is typically made for somewhere in the (near) future. In some cases, this is immediately followed by a (down) payment. Various payment providers are suitable for this purpose. But then comes the moment the reservation actually relates to. This is often on-site — think of an hour of bowling, a restaurant, a game of padel, or a meeting. In many cases, some form of catering is present. How convenient is it to settle the reservation right then and there, along with any additionally ordered items? That's where a point-of-sale integration comes in handy.
