Run locally or on Billing Cloud — you own the data. MIT license, full transparency, no vendor lock-in. One-line installer available.

Why it Matters

Own Your Billing Logic

Most billing platforms lock you into their pricing model, feature set, and data format. With Billing.net, you control the entire stack. Self-host on your infrastructure, customize workflows, and keep 100% of your billing data. No surprise fee increases, no forced migrations.

One API, Any Provider

Switch from Stripe to LemonSqueezy or add crypto payments without changing your application code. Billing.net provides a unified interface across payment processors, tax calculators, and email providers. Test new providers in parallel, migrate gradually, or run multiple providers simultaneously.

Integrate with AI Agents

The Model Context Protocol (MCP) enables AI agents to manage billing autonomously. Your Claude agent can create invoices, process refunds, update subscriptions, and analyze revenue patterns — all through standardized commands. Built for the AI-native future.

Predict Revenue with LLMs

Connect your billing data to language models for revenue forecasting, churn prediction, and pricing optimization. Billing.net's open architecture makes it easy to pipe transaction data into your analytics pipeline or AI workflow.

Keep Using Stripe — and Go Beyond It

Already using Stripe? Perfect. Billing.net doesn't replace it — it extends it.

Scenario	Without Billing.net	With Billing.net
Add Crypto Payments	Integrate new crypto API, manage wallets, reconcile payouts manually	Enable Coinbase MCP. Routes crypto invoices through existing billing logic — no code changes
Export for Taxes	Manually download CSVs from Stripe, PayPal, LemonSqueezy and merge them	One `/api/export/tax` endpoint ready for QuickBooks/Xero
Multi-Provider Resilience	If Stripe goes down, your app fails	Auto-fallback to PayPal or LemonSqueezy MCP. Customers never see failures
AI-Driven Insights	Build reports manually	Claude asks "What was MRR last month?" — instant answers from live data

Keep Your Stripe Integration

curl -X POST billing.net/api/invoice \
  -H "x-api-key: $KEY" \
  -d '{
    "provider": "stripe",
    "customer": "alice@acme.com",
    "amount": 4900,
    "currency": "usd"
  }'

# Same Stripe flow, 
# now logged + orchestrated

Add Crypto in Seconds

curl -X POST billing.net/api/invoice \
  -H "x-api-key: $KEY" \
  -d '{
    "provider": "coinbase",
    "amount": 0.05,
    "currency": "btc"
  }'

# Crypto payments enabled!
# Zero code changes

Keep Your Stack. Expand Your Reach.

Billing.net lets you keep your Stripe integration exactly as it is — and build beyond it. Add crypto payments, PayPal, or LemonSqueezy side by side. Export unified billing data to QuickBooks or Xero. Let AI agents manage invoices and predict revenue autonomously.

The Open Billing Server for Modern Applications

Billing.net is the world's first MCP billing orchestrator — an open-source server that connects to 23 billing MCP servers through one unified interface. Unlike traditional billing platforms that force you to implement REST APIs, Billing.net uses MCP-to-MCP communication to call Stripe MCP, PayPal MCP, LemonSqueezy MCP, Shopify MCP, and others directly.

Our MCP orchestration layer enables AI agents to manage billing across multiple providers without knowing their individual APIs. When Claude or ChatGPT calls our MCP server, we intelligently route to the best provider's MCP server, with automatic fallbacks to REST APIs when MCP isn't available. This creates a true universal billing hub for AI-native applications.

As a Stripe alternative, Billing.net doesn't replace your payment processor — it enhances it. Connect Stripe, LemonSqueezy, Paddle, or any payment provider through a single unified API. Switch providers without code changes, run multiple processors simultaneously, or build custom integrations for usage-based billing models.

The developer API is RESTful, well-documented, and includes SDKs for Python, TypeScript, and Go. Self-host the entire platform on your infrastructure using Docker or Kubernetes, or use Billing Cloud for a fully-managed experience. Every component is open-source under the MIT license.
