"We used to spend 20 hours a month manually calculating API usage for our 15 clients. Now it happens automatically. This tool literally pays for itself."
"The ability to set different markup rates for different clients is a game changer. We finally have a predictable recurring revenue stream from our AI implementations."
"I was skeptical about the proxy latency, but it's imperceptible. The client portal is what really sold us—our clients love seeing their own usage charts."
"Finally, a way to monetize my OpenAI credits without building a custom billing engine from scratch. Setup took less than an hour."
"The analytics are insanely detailed. I can see exactly which prompt is costing the most money and optimize it for my clients."

FAQ
Frequently Asked Questions
Everything you need to know about Bizgraph and how it helps agencies build recurring revenue from AI services.
An LLM gateway is a unified API layer that sits between your applications and multiple AI providers like OpenAI, Anthropic, and Google. It provides a single endpoint for routing requests, managing API keys, tracking usage, and controlling costs across all your AI integrations. Bizgraph extends this concept specifically for agencies, adding client management, custom pricing, and automated billing.
Bizgraph lets you set custom markup percentages for each client. When your clients make API calls through Bizgraph, we track the actual cost from the AI provider and calculate your markup automatically. You can see exactly how much profit you're making per client, per project, or per API key. Our automated invoicing feature (coming soon) will generate monthly invoices with full cost breakdowns.
Bizgraph supports all major LLM providers including OpenAI (GPT-4, GPT-3.5), Anthropic (Claude), and Google (Gemini). We use an OpenAI-compatible API format, so your existing code works without changes. You can route different clients to different providers or use multiple providers for redundancy and cost optimization.
LiteLLM and OpenRouter are developer tools focused on API routing and model access. Bizgraph is built specifically for agencies who want to create recurring revenue from AI services. We provide client management, per-client pricing controls, usage dashboards for your clients, and automated invoicing. If you're an agency billing clients for AI usage, Bizgraph handles the business side that other tools don't.
Yes! Bizgraph offers a 14-day free trial on all plans. No credit card is required to start. You can add clients, configure pricing, and test the full platform before committing. Setup takes about 5 minutes.
Yes! Client portals are coming soon. Bizgraph will provide client portals where your customers can view their own usage and costs. These dashboards will show your branding and the prices you've set (with your markup applied). Your clients will never see the underlying provider costs—they only see what you're charging them. Full white-label customization with custom domains will be available on the Agency plan.
