I have used https://github.com/iann0036/iamlive with great success in the past. On high level, the approach you are describing is iamlive on steroids and UX improved.
The free SKU allow you to start setting up and try out monitoring. You can change to paid SKU when you are ready to run more than 10000 API checks/month or 2500 synthetic checks/months.
We do not have per seat pricing. It's purely usage based and you can purchase additional checks as you go.
Wow. That seems to be a succession / resurrection of 2015-2016 projekt I was involved with Norwegian Consumer Council forbrukerrådet and some of major groceries chains(Coop, Rema, NG..)
The moment I left we were receiving soft real-time Pos log data (anonymized) and we’re building some consumer groceries basket stats.
Tele.ga has more features (RSS, sitemaps, etc.) that I still plan to implement for Telepost. The disadvantage of it that is built on top of the Bot API that has limited abilities. For instance, Tele.ga can't fetch history of your channel (works only for new posts) or handle message deletion request. Telepost has close integration with Telegram; your blog will be complete and always be up to date. Also, Telepost also doesn't require adding a 3rd-party bot to admins of the channel.
True. Especially if you are an owner and cashier at the said business.
But no so if the cashier is your employee. Keeping track of all small deals and ensuring most of them reaches your bank account and not your employee pocket might appear even bigger problem.
I know some small dining places where profits 3x skyrocketed since they introduced cards payments (in such places most of the profit comes from small things with crazy margins, such as tea or coffee)
