Built from real infrastructure
BillAI was born while we were building an AI logistics platform. We hit the same wall everyone hits — billing tools that couldn't keep up with complex, usage-based pricing. So we built something different: financial-grade infrastructure you can configure in plain English. Now we're making it available to every company facing the same challenge.
