Flexprice is an open-source billing engine that gives engineering teams full control over usage metering, pricing models, and subscription management without building billing infrastructure from scratch.
Flexprice provides APIs and infrastructure that help engineering, product, and finance teams design, launch, and iterate on pricing models without building or maintaining custom billing systems.
Teams can:
Ingest usage events in real time and translate them into billable charges automatically without any custom aggregation pipelines and reconciliation logic
Deploy as a fully managed service or directly into your own AWS account. Every deployment option includes full feature access, with no restrictions based on hosting choice.
Configure any pricing model such as usage-based, credit-based, seat-based, hybrid, or outcome-based and update plans, limits, and entitlements without code deployments
Run pricing experiments on a subset of customers, roll back instantly, and grandfather legacy plans without migrating billing systems
Issue credit wallets, promotional grants, and trial configurations directly from the dashboard
Generate invoices directly from verified usage and contract terms with automatic proration, consolidated line items across entities and regions, and tax compliance across VAT, GST, and sales tax without manual adjustments
Sync billing data across accounting, CRM, and payment systems so finance teams work from consistent numbers without reconciling at month-end
Flexprice is suitable for AI-native products, API platforms, and SaaS teams that require usage-based or hybrid billing integrated directly into their application stack.
Highlights
Meter usage and convert events into accurate billing through real-time APIs. No custom pipelines or reconciliation logic required.
Configure and update any pricing model through the dashboard or API without code deployments or engineering sprints.
Deploy as a fully managed service or in your own VPC. Full feature access across all deployment options.
AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
Pricing is based on the duration and terms of your contract with the vendor, and additional usage. You pay upfront or in installments according to your contract terms with the vendor. This entitles you to a specified quantity of use for the contract duration. Usage-based pricing is in effect for overages or additional usage not covered in the contract. These charges are applied on top of the contract price. If you choose not to renew or replace your contract before the contract end date, access to your entitlements will expire.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
This listing uses a contract model with three named plan tiers plus a separate usage fee. Build, Scale, and Enterprise form a progression: Build covers foundational billing and metering needs, Scale adds capabilities for growing teams and higher event volumes, and Enterprise adds flexibility and support for complex organizations. You commit to one plan tier for the contract term. The usage_fee dimension bills for consumption on top of your chosen plan, so total cost combines the tier commitment with metered usage. Higher tiers support larger event volumes and broader deployment options.
Top-of-mind questions for buyers
How do the plan tier commitment and the usage fee combine on my bill?
Your bill combines two parts. You pay for your chosen plan tier commitment, which sets your capabilities and event volume. The usage_fee then bills for metered consumption on top of that. Both charges apply together, so total cost equals the tier commitment plus your metered usage.
What counts as a usage event that the usage fee meters?
A usage event is a single ingested record sent to Flexprice through APIs, microservices, webhooks, or data warehouses. Each event is metered as it arrives. Plan tiers set monthly event volume limits, and the usage_fee dimension charges for consumption tied to these events.
How do the Build, Scale, and Enterprise tiers differ in deployment and support options?
Build and Scale run on the cloud platform. Scale adds prepaid credits, a customer portal, and pricing experiments. Enterprise supports cloud, VPC, or on-premise and air-gap deployment. Enterprise also adds SAML single sign-on, multi-role permissions, and 24/7 support with faster response times.
