"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."

Frequently Asked Questions
Everything you need to know about Bizgraph, the AI billing software that helps agencies bill clients and build recurring revenue from AI services.
Bizgraph is AI billing software built specifically for agencies managing AI services for clients. It automates usage tracking, applies custom pricing markups, and generates invoices automatically. Built on enterprise LLM gateway infrastructure, it routes API requests to OpenAI, Anthropic, and Google while tracking costs and calculating your profit margins in real-time.
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.
Most LLM gateways (LiteLLM, OpenRouter) are developer tools focused on API routing and model access. Bizgraph is AI billing software built specifically for agencies who need to bill clients for AI usage. We add client management, custom pricing markups, automated invoicing, and profit tracking—everything agencies need to turn AI projects into recurring revenue. If you're managing AI services for clients and need to bill them, Bizgraph is built for you.
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.
