What MarginWard Does

MarginWard is a margin analytics tool built for AI SaaS operators. It pulls read-only billing data from Stripe (customers, subscriptions, invoices) and matches it against LLM cost data captured through Langfuse, OpenRouter, or a direct ingestion API. The result is a per-customer view of gross margin that answers a question spreadsheets rarely can: which paying users actually make money after model tokens are subtracted from MRR.

Data Sources and Coverage

MarginWard supports usage cost tracking for the major model providers, including Anthropic, OpenAI, Google, and Mistral. When a model has no published price on file, MarginWard flags the usage rather than substituting an estimate, so the margin numbers stay grounded in real rate cards. Historical retention scales with the plan, from 30 days on the free tier to unlimited on the Growth and Scale plans, letting operators watch margin trends across releases and price changes.

Alerts and Security

Profitability alerts trigger when a customer breaches a threshold you set, so heavy users no longer surface only in the monthly close.
Read-only Stripe integration means MarginWard never moves money or edits subscriptions; it only reads what you already publish.
AES-256-GCM encryption is applied to stored API keys, and setup is documented as roughly a fifteen-minute task.

Plans

A free tier covers up to 25 customers, 30 days of history, and one cost source. Paid plans (Starter, Growth, Scale) raise customer counts, add teammates, extend history, and unlock API access on Scale. A 50 percent discount on the first three months is advertised as an introductory offer. Pricing is per the official site.

Pros & Cons

Pros

Answers who is actually profitable per customer, not just aggregate MRR
Read-only Stripe access reduces integration risk
Flags unpriced model usage instead of estimating a price
AES-256-GCM encryption for stored API keys
Fifteen-minute setup path with major cost sources

Cons

Value depends on connecting a cost source such as Langfuse or OpenRouter
Free tier is capped at 25 customers and 30 days of history
Only useful if you actually charge through Stripe

Frequently Asked Questions

Alerts trigger when a customer breaches a margin threshold you configure, so heavy users are surfaced continuously rather than only at month end.

Is there a free plan?

Yes. A free tier covers up to 25 customers, 30 days of history, and one cost source. Paid plans scale customer count, teammates, history, and cost sources.
