Billing migrations fail when they’re treated like feature releases. The safer approach is parallel run + reconciliation.
Low-risk migration steps
- Keep current billing as the source of truth.
- Mirror events into the new system.
- Run in parallel and reconcile outputs.
- Switch a small cohort first.
- Expand gradually with guardrails.
If you reply with your setup (provider, model, volume), you’ll get a practical migration path.
Neruba supports parallel-run reconciliation so teams avoid big-bang cutovers.
