Finance system that works with Sims

Hi All, We use Sims in our schools, our current finance system has no any native way of working with Sims. We build custom integration tools, but these are not great and our software developer guy left. So we are looking for something better that has some kind of integration with Sims. I used Sims Finance before in my previous school, we are waiting to hear about new development coming together with Sims Next Gen, but Parent Pay group are really quiet about it. Please let me know any suggestions
