From raw events to billable line items
Send usage events via API or connect your data warehouse. Enso handles structured and semi-structured event payloads at any scale.
Events are bucketed, deduplicated, and aggregated against your contract's pricing rules: usage tiers, rate cards, caps, and minimums.
Aggregated usage is priced per customer contract and surfaced as billable line items ready for invoice generation.
Support any pricing model your sales team can sell
- Usage-Based Pricing
Enso's usage billing software handles per-request, per-GB, and per-seat models. Ingest events and apply any unit-based pricing formula without engineering work.
- Tiered and Volume Pricing
Automatically apply graduated rate tiers and volume discounts as customers cross thresholds mid-month.
- Hybrid Models
Mix flat subscription fees with usage overages in a single invoice. Common in enterprise SaaS deals.
- Outcome-Based Pricing
Charge customers based on results delivered: successful transactions, models run, or conversions. Not just raw usage. Enso maps outcome events to contract terms automatically.
- Real-Time Visibility
Finance and sales can see live usage against contract commitments before invoices are generated.
Our pricing model has flat fees, per-API-call charges, and volume discounts that kick in at different thresholds. Enso handles all of it without a single line of custom code.
