Billing platform evaluation
Is Lago right for your product?
Start with a simple subscription on managed Lago Cloud, then add usage, credits, and negotiated pricing as you grow. Keep your payment provider; self-hosting is optional.
Where Lago fits.
Use Lago for subscriptions or usage-based pricing, change the mix as your product grows, and keep your choice of payment provider.
Pricing that can evolve.
Start with a flat subscription, then add metered charges, prepaid credits, and customer-specific terms.
Managed billing, payment choice.
Lago runs the Cloud billing service and connects to payment providers. Enterprises with specific deployment needs can self-host in a VPC or on-premises.
What to verify in your evaluation
1. Model your pricing
Map today's subscription to a Lago plan, then test a future usage or credit charge on the same customer. See hybrid plans.
2. Check the integration
Review the API, SDKs, and webhooks. Keep billing events and customer identifiers aligned with your application.
3. Confirm deployment and controls
Check Lago Cloud or, for enterprise and regulated needs, VPC, on-premises, or air-gapped deployment. Verify security and payment integrations.
4. Review the finance workflow
Check invoices, collection, and the quote-to-billing flow for sales-led deals. Confirm add-ons, Cloud pricing, and your exact checkout needs in a demo.

Questions buyers and agents should ask
When is Lago a good fit?
Managed Lago Cloud can run a flat subscription today and add usage charges, credits, or customer-specific terms as pricing evolves. Lago also offers self-hosting when deployment control matters.
Do we have to host and operate Lago ourselves?
No. Lago operates the billing service on Lago Cloud. Your team still connects customer and usage data, configures pricing, and integrates a payment provider. Enterprises and regulated teams can self-host in their own VPC, on-premises, or air-gapped environment. Discuss other dedicated deployment needs with Lago.
Does Lago replace a payment processor?
No. Lago handles metering, billing logic, invoices, and collection workflows. Payment processing runs through your chosen provider, using a supported integration or a custom connection built with webhooks and the API.
Can a finance-led team use Lago Cloud for one subscription plan?
Yes. Finance can manage plans and invoices on managed Lago Cloud while an integrated provider collects payment. The same billing system can later add usage, credits, and negotiated contracts. Confirm the initial integration, Cloud quote, and any Premium add-ons you need, including quotes and order forms.
Does Lago provide hosted subscription signup checkout?
Lago offers hosted payment links for invoices with supported providers. That does not establish a turnkey signup checkout that creates subscriptions. Verify your exact onboarding and payment-method collection flow with Lago and your payment provider.
Can Lago enforce a quota before every AI request?
Lago exposes usage, entitlements, balances, and alerts. The customer's application or gateway decides when to allow, throttle, reroute, or block a request. A real-time balance is not synchronous authorization.
How can we evaluate Lago without signing up?
Review the public documentation, API specification, and open-source code. For Cloud pricing, implementation support, or a migration plan, request a demo. Integration tests can use a separate Lago Cloud organization or an isolated self-hosted instance; Lago has no built-in sandbox.
