A usage-based billing engine for enterprise contracts, replacing spreadsheet reconciliation with config-driven pricing.
The client runs enterprise billing inside a regulated fintech environment where every contract carries custom pricing and needs compliance review. Their spreadsheet-based process broke down as contract terms got more varied across customers.
Finance managed usage-based billing through spreadsheets, reconciled by hand against a homegrown metering system. Every contract had its own terms, tiered pricing, overage rules, and SLAs, which made reconciliation errors routine and turned dispute resolution into a weeks-long process.
Contract terms and SLAs are now defined as configuration records instead of hardcoded logic, so finance can launch new contract structures without engineering. Automated metering reconciliation surfaces discrepancies immediately, and a complete audit trail documents every billing calculation for compliance and disputes.
Reconciliation time dropped 90%, billing disputes fell 76% in the first two quarters, and every billing calculation now carries full audit coverage.
