Lago vs Stripe Billing is a choice between two opposite failure modes. Stripe Billing is subscription-native with metering bolted on, so metering depth becomes your ceiling. 

Lago is metering-native with thin enterprise contract handling, so contract complexity becomes your ceiling. 

We've watched teams pick the wrong one because nobody asked which layer their complexity actually sits in.

Key Takeaways

• Stripe Billing costs 0.7% of billing volume and includes the Meters API up to 100M events monthly, then routes advanced usage-based billing to Metronome.

• Lago's AGPLv3 core is free to self-host, but the customer portal, RBAC, and credit notes sit inside Lago Premium, priced on request.

• Stripe Billing wins on subscription lifecycle: quotes, multi-phase schedules, Smart Retries, and the customer portal all ship inside the 0.7%.

• Neither handles ramped contracts, parent-child accounts with consolidated invoicing, or credit pooling across departments.

How does Lago vs Stripe Billing compare for complex metering?

Lago meters more deeply, Stripe Billing manages subscriptions more completely, and both stop at the same wall, enterprise contract complexity. Stripe says the quiet part out loud on its pricing page: basic usage stays in the Meters API, anything advanced goes to Metronome. Lago handles usage-based billing natively without a second vendor, but asks more of you on the contract side.

Metering depth

Lago prices multiple things off one event stream, and Stripe Billing mostly can't. Lago filters on event properties inside a single billable metric, so one metric prices by model or by input versus output type. Stripe Billing has no documented way to filter within a single usage event, so charging GPT-4 differently from GPT-4o needs a separate usage schema per variant. Fine at two models. Painful at twelve.

Timing matters too. Stripe processes meter events asynchronously, and its docs warn that aggregated usage may not immediately reflect recent events. For new integrations, Stripe now recommends Metronome over Billing Meters. I'd rather a vendor say that plainly than let me find out in production, and to Stripe's credit it does.

We're not quoting events-per-second figures for either product, because Lago's own number and the third-party comparisons sit two orders of magnitude apart with no checkable benchmark.

Subscription management

Stripe Billing is the more complete subscription product, and it isn't close. The 0.7% fee includes quotes, multi-phase subscription schedules, Smart Retries, overdue payment reminders, invoice auto-reconciliation, and a customer portal, with tax and revenue recognition in the same stack. That's a lot of solved problems for one line item.

Testing is the underrated part. Stripe's test clocks let you walk a subscription forward in time and watch the lifecycle fire. As one engineer put it on Hacker News after evaluating both: "Stripe Billing with its test clocks blows Lago out of the water here. Lago has no ability to walk the clock forward for subscription lifecycle testing."

Lago's constraints here are structural. Its entitlements couple to the subscription lifecycle, plan to subscription to feature, so your app checks subscription status itself and per-customer overrides get awkward at scale. Core plan properties like billing interval and proration lock once a plan has subscribers, so real pricing iteration means new plans and customer migrations.

Lago and Stripe Billing side by side

Every row traces to a vendor's live page or our own research. Anything we couldn't confirm says so.

Note for the CMS: this table ships as raw HTML in the publish file. It is rendered as markdown here only so the Doc reads cleanly.

Where both fall short

Enterprise deals keep surfacing five capabilities neither product covers cleanly: ramped contracts, parent-child accounts with consolidated invoicing, credit pooling across departments, recurring credits with rollover, and entitlements that enforce a number rather than a yes or no. Each becomes a backend code you own forever.
