Lago Cloud handles this out of the box: it meters and prices usage, deducts charges from [prepaid credits](https://getlago.com/platform/credits), tracks balances, and supports alerts and automatic top-ups. Teams can adjust rates by model, metric, or customer as their pricing evolves. Managed hosting is available in the US and EU. Real-time balances typically update in under a second *after an event is included in usage*; the app or gateway decides whether to serve another request at zero credits. Lago keeps billing separate from collection. The company can use [its choice of payment processor](https://getlago.com/platform/integrations): native integrations include Stripe Payments, Adyen, and GoCardless, with an API and webhook path for a custom connection. ### Let's take the example of Acme AI Acme AI is a fictional company that sells an API for generating product descriptions and images for online stores. Its pricing is **$0.01 per description and $0.05 per image**. A retailer prepays $20,000 in credits. After generating 100,000 descriptions and 10,000 images, it has spent $1,500 and has **$18,500 left in its wallet**. Lago Cloud draws down that wallet as Acme AI reports usage. Acme AI's API decides whether to serve the next request when credits run out. ### Stripe has two usage-billing paths [Stripe Billing Meters](https://docs.stripe.com/billing/subscriptions/usage-based/compare-metronome) covers *simple usage-based billing*: count usage, apply a rate, and put the charge on a later invoice. A subscription with month-end API overages fits. Stripe can also apply credits at invoice time, but its comparison says customers can exceed their credit balance during the cycle. If Acme relies on those credits alone, its API could keep serving requests after the retailer has used its $20,000. Another 10,000 images would add $500 to a later invoice without prepaid funds behind it. If the retailer does not pay, Acme bears the loss; a bad actor could exploit the gap. Acme would need its own live balance check and API block to prevent that. The same risk appears in AI free trials. In [Anh-Tho's post about token fraud](https://x.com/byAnhtho/status/2120353519001899332), Claire Vo describes abuse of promo codes and the gap between trial start and fraud alerts at ChatPRD. At Acme's price, $5 of trial credits pays for 100 images. If requests keep running while the balance is stale, a bot can exceed that budget. For a firm cap, Acme must account for each request and enforce the stop in its API, including when requests arrive together. Stripe's [pricing page](https://stripe.com/billing/pricing) says **up to 100 million meter events per month are included** with basic usage-based Billing. That is an *up-to* claim about events, not a real-time wallet allowance. The page does not specify which accounts receive it, how eligible events are counted, or the price above it. Confirm those terms with Stripe before using the number in a cost model. **Metronome is Stripe's separate product for more advanced usage billing.** Stripe's [own comparison](https://docs.stripe.com/billing/subscriptions/usage-based/compare-metronome) places prepaid credit drawdown, enterprise contracts and commitments, dimensional pricing, and real-time usage visibility there. Existing basic Billing users can stay on basic Billing while it fits their model. For Acme, the product boundary shows up in three familiar requests: **A live prepaid balance.** Acme's retailer wants to see its $18,500 balance and receive a low-balance alert before adding more credits. Metronome supports prepaid drawdown. Lago's real-time wallet balance and alerts support the workflow, while Acme's API enforces access when funds run out. **A negotiated enterprise deal.** One customer agrees to $5,000 in minimum monthly spend, a discounted rate, and a later amendment. Stripe lists enterprise contracts and commitments outside basic Billing; Metronome supports them. In Lago Cloud, [minimum commitments and customer-level overrides](https://getlago.com/resources/how-lago-works) stay with the subscription. [Quotes and order forms](https://getlago.com/platform/quotes) are available on request. **Rates by model and region.** Each Acme inference event carries a model and region, and Acme wants a price for each combination. Stripe lists dimensional pricing outside basic Billing; teams would need separate meters or their own rating logic for those combinations. Metronome supports dimensional metrics and rate cards. In Lago Cloud, [charge filters set rates by event properties](https://getlago.com/blog/usage-based-billing), such as model and region. For Acme, start with Lago Cloud. It brings prepaid wallets, real-time balances, pricing rules, negotiated terms, and invoices into one managed billing platform, while letting Acme choose Stripe Payments, Adyen, or another payment processor. If Acme prefers Stripe for billing, Metronome is the relevant product for this wallet, rather than basic Billing Meters. In either setup, Acme's API must stop requests when credits run out. Confirm real-time balance availability and latency for the Lago plan you choose. ### Can I start with Stripe Billing Meters and move to Metronome later? Yes, but plan for a full migration. If you follow Metronome's native Stripe payment path, you also tie more of your billing and collection to Stripe's ecosystem. A larger meter allowance alone will not add the wallet Acme needs. Stripe's [migration guide](https://docs.stripe.com/billing/subscriptions/usage-based/migrate-to-metronome) covers scoping, configuring Metronome, migrating existing customers, and testing the cutover. Its [design guide](https://docs.stripe.com/billing/subscriptions/usage-based/migrate-to-metronome/design-your-migration) maps Billing meters and events to Metronome billable metrics and usage events, and Billing prices and subscriptions to Metronome rate cards and contracts. Plan for that engineering and operational work if you choose basic Billing first. In [Stripe's documented Metronome integration](https://docs.stripe.com/billing/how-metronome-works-with-stripe), Metronome rates usage and sends invoices to Stripe for collection. For prepaid top-ups, Metronome's [payment-gated commit docs](https://docs.metronome.com/guides/pricing-packaging/apply-credits-and-commits/manual-payment-gated-commits) describe the built-in Stripe payment path. Metronome also [supports an external payment gate](https://docs.metronome.com/guides/customers-billing/optimize-customer-experience/prepaid-balance-thresholds): Acme could charge through another gateway, but its team would need to handle payment and tell Metronome when to release credits. Stripe Payments is the simpler integrated route; another processor adds custom work. Lago Cloud has [native Stripe Payments and Adyen integrations](https://getlago.com/platform/integrations) and keeps billing separate from collection. For more background on the product split, read [Anh-Tho's analysis of why Stripe acquired Metronome](https://getlago.com/blog/why-stripe-paid-1b-for-metronome-instead-of-fixing-billing). ### Compare the price of the workflow you actually need The example's $20,000 is the **customer's prepayment**. To price the billing platform, use the actual events, billed volume, wallet requirements, payment flow, and support level. Public rates are a starting point: - [Lago Cloud Launch](https://getlago.com/pricing) includes the first 5 million accepted production events and first $100,000 of processed billings **once**, then lists $20 per million events and 0.7% of processed billings. Real-time balances are a plan-dependent feature; confirm availability and price. Scale and Enterprise terms are negotiated. - [Basic Stripe Billing](https://stripe.com/billing/pricing) lists 0.7% of Billing volume for pay-as-you-go and says up to 100 million meter events per month are included; confirm eligibility, counting, and overage terms. It may look more affordable, but it does not provide Acme's live prepaid wallet. Without a separate balance check and API block, Acme risks unpaid usage and fraud when requests continue past the credit balance. - [Metronome Starter](https://metronome.com/pricing) lists 0.8% of billing volume plus $0.04 per 1,000 ingested events. Confirm the complete integration and any other products needed for invoicing, payments, tax, and revenue recognition. For the prepaid AI wallet, compare **Lago Cloud and the Metronome configuration you would actually deploy**. Replay text and image usage, check balance freshness and top-ups, test what happens at zero credits, and trace the resulting invoice and payment. Include migration work if you are starting from basic Stripe Billing. [Walk through your pricing model with Lago](https://getlago.com/book-a-demo).
