Polar

Polar is a billing platform for the AI era with support for usage-based, subscription, and credit billing. It offers native AI token metering and inference billing, making it purpose-built for companies selling AI model access. Built-in global tax compliance and fraud protection reduce operational overhead, while real-time usage metrics and revenue dashboards give you full visibility into your billing operations from day one. The platform does not include a built-in CRM or contract management, and enterprise contract customization is limited, but for AI-native billing it leads the category.

Pricing starts at 4% + 40¢ per transaction.

Solvimon

Solvimon provides end-to-end billing, CPQ, and revenue operations designed for hybrid pricing SaaS businesses. It unifies CPQ, billing, payments, and revenue operations while supporting hybrid models that combine seats, usage, and credits. Integrations with Salesforce, HubSpot, and NetSuite make it a natural fit for growth-stage companies already using those platforms. The trade-off is a steeper learning curve and a higher price point compared to simpler billing tools, but for complex pricing models it delivers the most complete solution.

Best for SaaS companies with complex hybrid pricing models.

Pricing is custom, with the first $3M free for AI startups.

Dodo Payments

Dodo Payments is a billing and payments platform built for AI-first companies, specializing in credit-based billing models. It acts as a Merchant of Record to handle global tax compliance so you do not need to manage VAT, GST, or sales tax yourself. The MCP Server enables direct AI agent integration, and the platform supports credit-based, usage, and subscription billing in a single system. As a newer platform, it has a smaller user base and limited ERP integrations compared to incumbents, but it is purpose-built for the AI billing landscape.

Best for AI startups needing credit-based billing and global payments.

Standard pricing is 4% + 40¢ per transaction, with custom Enterprise plans available.

Owostack

Owostack delivers billing infrastructure for AI SaaS that can be set up with just three API calls. It includes pre-built pricing models modeled after successful AI companies and works with any payment processor, so you are never locked into a specific gateway. The provider-agnostic approach and minimal setup make it one of the fastest ways to add billing to a new SaaS product. It is still early-stage with limited enterprise features, and documentation and community resources are still growing, but for speed of integration it is unmatched.

SuperBill

SuperBill is a fully autonomous AI agentic billing platform featuring four AI agents that manage billing operations end-to-end. It includes automatic failed payment recovery with intelligent retries, reducing revenue leakage from involuntary churn. Real-time revenue intelligence and upsell recommendations help you maximize revenue from your existing customer base. As a newer entrant with limited market track record and enterprise-focused pricing, it is best suited for companies ready to invest in hands-off billing automation rather than early-stage startups watching every dollar.
