Every billing function any recurring-revenue business needs — plans, trials, proration, dunning, coupons, add-ons, usage metering, invoicing, and outbound webhooks — built to work together without configuration. SaaS, marketplaces, e-commerce, insurance, utilities, media — any business where customers pay on a schedule.
Most billing systems require you to build the edge cases yourself — trial conversions, mid-cycle upgrades, dunning retries across different payment methods, proration credits. ZenoPay handles all of it as first-class behavior.
Create pricing tiers with configurable usage entitlements per feature. Monthly and annual intervals. Archive plans without breaking existing subscriptions. Entitlements enforce limits with hard caps or overage billing.
Start, extend, and convert trials with a single API call. Configurable trial length per plan. Automatic first-charge execution on conversion with full rail-scoring applied. Bulk expiry for stale trials.
Mid-cycle upgrades and downgrades calculated to the day. Credit for unused time on the old plan applied against the charge for remaining time on the new plan. Net amount billed immediately.
Configurable retry schedules after failed payments — day 3, 7, 14, 21 by default. Each retry routes across all configured rails before failing. Grace period before cancellation is triggered.
Pause subscriptions with a defined duration — billing stops, access can be maintained. Resume restores the subscription to active with a new billing period. Full audit log entry written for every state change.
Sequential invoice numbering with configurable prefix per tenant. Line items, tax calculation, period tracking. AI-generated natural language summary on each invoice. Full invoice history queryable via API.
Most businesses outgrow flat-rate billing. ZenoPay has seat-based pricing, per-unit usage, promotional coupons, and tiered add-ons built as native billing primitives — not workarounds.
% off, fixed amount, or free months. Once, repeating N months, or forever. Max redemption caps and expiry.
Per-unit, flat, and tiered pricing billed alongside base subscriptions. Seat management for team plans.
Track feature usage per customer. Enforce limits or bill overages per unit above the plan threshold.
24 event types. HMAC-signed payloads. Retry queue for failed deliveries. Configurable endpoint per tenant.
Define pricing tiers with feature limits, overage rates, and billing intervals. Plans are created via API and immediately available for subscription assignment.
Subscription created with period dates calculated. Trial subscriptions start with status TRIALING. Immediate subscriptions charge first cycle on creation.
Churn scoring runs daily on every subscriber. Failed payments trigger dunning automatically. Usage approaching limits fires warning webhooks.
Each renewal is routed through the optimal payment rail, charges executed, invoices generated, and events fired — without any manual intervention.
Subscription management is one of six integrated systems. Every billing event feeds into churn scoring, fraud detection, and the autonomous brain.
