Flexprice

What Flexprice does

Flexprice records product-consumption events in real time, aggregates them for billing, and turns the data into invoices. It is built for AI and SaaS products that charge by subscription, usage, credits, seats or combinations of these.

Plans can set feature access and usage limits. Credits, wallets, expirations, rollovers and overage controls handle prepaid usage, while cost sheets compare customer revenue with serving costs.

Fees and plans

The free offering processes as many as 100k events each month and covers up to $100K in cumulative billing revenue. It provides subscription, usage-based and hybrid pricing, tax management, billing webhooks and PDF invoices. A 30-day trial is also listed, but its plan terms are not detailed.

For $500 per month on monthly billing, Build supports 1 million events monthly. This tier adds real-time metering and reporting, PDF invoices, customer usage views, Stripe Payments, prepaid credits and API key management.

Scale is priced at $1,000 per month, billed monthly, and covers 5 million events each month. Its features include prepaid credits and wallets, a customer portal, multi-currency and multi-timezone billing, HubSpot, Stripe Tax and 50-plus integrations, plus Google SSO and audit logs.

Pay as you go costs $199 a month plus 0.5% of billing, for up to 50 million usage events monthly. The tier supports subscription, usage-based, hybrid and credit pricing, along with real-time metering and SQL metrics, credits, wallets, entitlements, PDF invoices, a customer portal, and multi-currency and multi-timezone billing.

Enterprise starts at $3,000 a month with no revenue share. It includes VPC, on-premise or air-gapped deployment, HubSpot, Stripe Tax and 50-plus integrations, SAML SSO, SCIM, role-based permissions, SOC 2 Type 2 and GDPR compliance, and 24/7 support with a 30-minute P0 response.

Mission Critical is price on request. It offers custom event volumes, cloud, VPC or on-premise deployment, SAML SSO, SCIM, advanced entitlements, alerts, budgets, dunning, payment retries and draft-invoice editing.

Where it runs

Flexprice is published for web, Linux, API use and self-hosting. Documentation covers backend self-hosting, AWS deployment and frontend hosting; commercial plans also list VPC and on-premise options.

No iPhone or Android app is listed in the published platform information. Official JavaScript/TypeScript and Go SDKs are available, and an MCP server exposes the API to AI assistants.

Protection and rules, as published

Flexprice states that it is SOC 2 Type II, GDPR and ISO 27001 compliant and provides a separate trust center. The Enterprise plan lists SOC 2 Type 2 and GDPR compliance.

The provider's marketing site claims 99.9% or higher uptime and sub-second processing latency for millions of billing events. It publishes email and community Slack support, with response-time commitments tied to plans.

Strengths

The platform covers real-time usage metering, several pricing models, entitlements, prepaid wallets, invoicing and customer usage views in one system.

Pricing experiments and sandbox testing allow proposed changes to be checked before production. Published connectors include Stripe, Razorpay, Chargebee, HubSpot, Zoho Books, QuickBooks, Paddle, Moyasar and Whop.

Open-source core code, extensive documentation and SDKs for JavaScript/TypeScript and Go give technical teams several deployment and integration paths.

Catches to check

Self-hosting may require substantial setup. A Reddit user described difficult front-end and back-end installation and documentation that led them in circles.

The same discussion reported a missing integration for a team that wanted metering and entitlements while keeping billing elsewhere. NetSuite is not on Flexprice's published integration list.

Plan limits vary from 100k events monthly on Free to 50 million on Pay as you go, and several features require higher tiers. The core repository is AGPLv3, while a small Enterprise Edition portion uses a commercial license.

Who may want another tool

Teams wanting a phone app, a listed NetSuite connector or a simpler hosted setup may find the published options unsuitable.

Verdict

Flexprice fits technical AI and SaaS teams that need usage metering tied to billing, credits, entitlements and invoices, with options for self-hosting or managed deployment. Its free tier and open-source core provide an entry point, while paid plans add event capacity, portals, currencies, identity controls and enterprise deployment choices.

It is a weaker match for organizations that need a mobile application, NetSuite connectivity or a low-effort self-hosting experience. The pricing structure also differs by plan, with event ceilings, revenue-share terms or custom quotes that should be understood before selecting a tier.
