Still happy customers, after five years. We use JustOn since 5 years in our Org. The migration from our old billing system has been a lot of work, but totally worth it. For everyone who is looking into digitizing processes and billing in Salesforce directly, don't look any further. 

It's good to see JustOn developing from year to year and adapting quickly to regulation / new law requirements. The recent upgrade to the new version has been an important milestone for us and we are very thankful to the great support we received.
