Usage-Based Billing Software That Actually Works
Usage-based billing software automatically meters customer consumption, calculates charges against contract thresholds, and generates invoices without spreadsheets. LedgerUp's AI agent Ari handles metered billing for B2B SaaS companies with hybrid contracts—HappyRobot recovered $72.5K in unbilled overages within 30 days.
Why usage billing breaks without LedgerUp
Most teams track overages manually, leading to revenue leakage, billing disputes, and wasted engineering time before LedgerUp replaces the busywork.
Revenue Leakage
Usage-based overages calculated manually using spreadsheets. Complex formulas break regularly, letting billable usage slip through unbilled for months.
Manual Overage Math
Calculating usage overages requires pulling data from multiple systems, running formulas, and double-checking every result. A single billing cycle can take 5–7 days.
System Sync Failures
Invoice data in Stripe frequently falls out of sync with contract terms in your CRM. Discrepancies take hours to resolve and erode customer trust.
How LedgerUp handles usage billing end-to-end
From monitoring usage thresholds to generating and sending overage invoices, LedgerUp automates the full workflow.
Automated Overage Calculation
Ari continuously monitors usage against contract thresholds and calculates overages automatically - no spreadsheets, no broken formulas.
Contract-Aware Metering
Ari reads your contracts and understands per-unit pricing, tiered thresholds, and overage terms. Billing always matches what was agreed.
Real-time Usage Tracking
See exactly where every customer stands against their usage limits. Get notified in Slack the moment an account exceeds their threshold.
Automatic Invoice Generation
When usage triggers an overage, Ari generates the invoice, syncs it to Stripe, and sends it - all without human intervention.
