FOSSBilling as WHMCS Alternative
I've seen many posts about this, but I wanted to start this thread to ask for recent experiences from those who have tried it.
We started with WHMCS because it allowed us to get up and running very quickly and gave us a solid foundation for our service management platform, primarily for hosting. Since we also develop other types of SaaS products, we've been using it for that as well.
But from the beginning, we've had the problem that WHMCS customization, especially the client area, isn't very developer-friendly. Furthermore, trying to expand it makes it very unintuitive. Another problem is that WHMCS's overall performance is too slow for our standards compared to the custom services we develop. And now, due to our dependency on a third-party platform for the client area, we want to migrate it to React, but the API is limiting us somewhat, and as I mentioned, expanding it is becoming very tedious.
However, from the beginning, we've had the problem that WHMCS customization, especially the client area, isn't very user-friendly. And of course, there's the issue of price. Our biggest expenses are for WHMCS and Plesk licenses, which we want to get rid of eventually (we'll replace Plesk with our own solutions that are already in the testing phase).
Obviously, we've already assessed these problems and decided to create our own solution that will allow us to easily modify and expand it as we wish using Go and Node.js. However, this will take a lot of time, and honestly, we want to finish developing other products right now. Until then, we plan to take an intermediate step by testing a pre-built backend like FOSSBilling. From what little I've seen of it, I liked how intuitive the API is for modification, and we plan to test it on a test server and, of course, migrate until we have our own solution.
So, I'm asking to this community: What did those of you who tried FOSSBilling think? How was your migration, if you had one?
