How does Flexprice define what counts as a usage event?

Can Flexprice ingest data from my existing systems?

Yes, Flexprice can ingest usage data from any source APIs, microservices, or event streams so you don’t need to rebuild your data pipelines.

How does real-time aggregation help with billing accuracy?

Real-time aggregation ensures all usage data is processed and updated instantly, so your billing reflects the most accurate customer activity without lag or discrepancies.

How do I verify the data being ingested by Flexprice?
