# Chargebee Alternative? Why Teams Choose Lago for Usage-Based Billing

If your next product launch adds AI credits, usage priced by model, or a negotiated rate card, start by testing Lago Cloud. Chargebee can bill subscriptions and usage, and it now offers a prepaid-credit ledger. The reason to consider a switch is more specific: can your team change how usage becomes a charge, a credit balance, and an invoice without rebuilding that logic in your application?

This article is a practical guide to that decision and to a safe migration. For a feature-by-feature evaluation across self-serve and enterprise workflows, read our [Lago vs. Chargebee comparison](https://getlago.com/blog/lago-vs-chargebee).

### Prove your next pricing change

Take a change you expect to sell this quarter. For example, you charge a monthly platform fee, bill input and output tokens at different rates for each AI model, give customers prepaid credits, and negotiate one enterprise rate. Put that same case into both systems. Then change the price of one model and trace the result from event to invoice.

In Lago, your application sends usage events. You define [billable metrics and calculations](https://getlago.com/docs/guide/billable-metrics/aggregation-types/overview), use [charge filters](https://getlago.com/docs/guide/plans/charges/charges-with-filters) to price dimensions such as model or region, and apply [customer-level price overrides](https://getlago.com/docs/guide/subscriptions/assign-plan) where a contract calls for them. [Wallets and credits](https://getlago.com/platform/credits) give customers a view of what they have left. Lago's ongoing balance refreshes every minute; your application uses the balance and webhooks to decide when to warn or restrict access. If a hard cap under concurrent usage is essential, test that requirement separately.

Chargebee also supports [usage-based billing](https://www.chargebee.com/docs/billing/2.0/usage-based-billing/usage-based-billing-usecases) and [prepaid-credit units](https://apidocs.chargebee.com/docs/api/credit_units). Its [Capture API](https://apidocs.chargebee.com/docs/api/ledger_operations/capture) accepts the number of credits your application sends for a completed action. The prepaid-credit feature is in early access, so confirm availability in your proposal. Ask each vendor to show where a product action becomes a credit amount, where the rate is configured, what your engineers must deploy, and how Finance can explain the resulting charge.

Lago Cloud gives you a managed service with an open-source billing engine your engineers can inspect. You can [build with its API, SDKs, webhooks, CLI, and MCP server](https://getlago.com/developers). If your deployment requirements call for it, Lago also offers [Premium self-hosted and an open-source edition](https://getlago.com/pricing). For most teams evaluating a move from a managed billing platform, Lago Cloud is the simplest place to run the test.

### Move one billing cycle, not every record at once

Before you choose a migration date, map the parts of your current billing setup: plans and addons, customer-specific prices, subscription dates, usage events, remaining credits, unpaid invoices, taxes, and payment collection. Identify which system owns each record during the transition. Confirm how existing payment methods and historical invoices will be handled with your payment provider and Finance team; do not assume they transfer automatically.

Start with a representative sample: a self-serve subscription, a usage-heavy customer, and a negotiated contract. Replay or send sample usage to Lago Cloud and [preview the invoices](https://getlago.com/blog/invoice-previews). Compare totals, credits, proration, tax treatment, and payment status with the expected result. Run a sample month in parallel without charging the same customer twice. Move a cohort only after the team can explain every material difference.

There is no universal two-week migration. A simple catalog and a complex contract book have different data and integration work. The useful milestone is a verified billing cycle, not a promised setup date.

### Make the decision with five checks

1. **Pricing changes:** How many configuration changes and code deployments does a new AI model, region, or enterprise rate require?
2. **Credits:** Where is usage converted into credits? How current is the balance customers see? What happens when usage is concurrent or the balance reaches zero?
3. **Invoices:** Can Finance trace every line item back to the contract, usage, price, credit, and tax calculation?
4. **Customer journeys:** Can customers sign up, change plans, see usage, pay, and recover from a failed payment in the experience you want to offer?
5. **Migration and cost:** What must be imported or rebuilt, which features are available in your proposal, and what will the full operating cost be?

If Lago Cloud makes your next pricing launch easier to configure, test, and explain, move the first cohort. Keep Chargebee in place for the rest until the parallel run reconciles. That is a stronger reason to switch than a feature checklist or a claim that one platform cannot handle usage.
