Looking to build a datacenter billing software and looking for guidance, so that we don’t need to start from scratch.
We checked so far
Open Cost - It is only observability platform. This can be used a starting point for metrics collection.
Then we need a rate plan, various ways to modify or give discounts on the rate plan based on usage, volume, time etc.
We looked at Kill-Bill as a viable solution, but seems a bit overboard.
If someone can give pointers, we are happy to share our product to the community as we develop.
