Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Flexprice is a billing and monetization platform for AI and SaaS companies managing subscription, usage-based, credit-based, seat-based, and hybrid pricing. It combines real-time metering, rating, invoicing, subscription lifecycle management, payment integrations, reporting, and APIs. The platform is aimed at engineering, product, finance, and enterprise billing teams that need to manage complex pricing and usage-based revenue workflows across web, API, or self-hosted deployments.
The published plans show a permanent Free tier with 100k events per month, up to $100K in cumulative billing revenue, tax management, billing webhooks, and PDF invoices. Build costs $500 per month when billed monthly and adds 1 million events, real-time metering and reporting, Stripe Payments integration, prepaid usage with credits, and API key management. Scale costs $1,000 per month monthly and adds 5 million events, customer portals, multi-currency and multi-timezone billing, HubSpot, Stripe Tax, 50+ integrations, Google SSO, and audit logs. Mission Critical uses custom pricing and adds deployment choices, SAML SSO, SCIM provisioning, advanced entitlements, alerts, budgets, dunning, payment retries, and draft invoice editing.
Flexprice fits teams whose pricing logic requires more than standard recurring subscriptions. Its combination of proration, prepaid credits, wallets, overage rules, usage views, customer portals, APIs, SDKs, and webhooks supports detailed billing workflows, while open-source and self-hosted options provide deployment flexibility. Payment processing integrations and retries also connect billing operations with collections. Developers building complex usage billing should consider it, particularly when multi-currency support or self-hosting matters. Teams seeking only straightforward invoicing or basic subscription billing may find the $500 monthly starting point and broad feature set harder to justify.
