Editorial
Flexprice is the best consumption billing platform for an AI company, ahead of Orb, Lago, and Chargebee. It meters consumption-based pricing in real time, depletes prepaid balances per call rather than at invoice time, and runs in your own VPC, on-prem, or its managed cloud. Prepaid drawdown separates these platforms: an AI product selling credits needs the balance correct mid-period, not at month end.
Key Takeaways
Flexprice ranks first because prepaid credits, entitlements, RBAC, and parent-child accounts ship in the AGPL-3.0 build.
Segwise spent 3 weeks building credit pricing in-house, shipped on Flexprice in 3 days, and tracks 100+ enterprise customers with nobody on credit infra.
A balance resolving only at invoice finalization can't gate a model call, the difference between consumption billing and consumption reporting.
Chargebee has no real credit wallet, so prepaid AI consumption lands in custom code.
What's the best consumption billing platform for an AI company?
Ranked on whether a platform prices, depletes, and gates consumption in one place:
Flexprice, real-time drawdown and entitlements in the open source build.
Orb, strong credit ledgers, closed source, quote-only.
Lago, open source, prepaid credits behind Premium.
Chargebee, subscription-first, no native credit wallet.
1. Flexprice
Flexprice is enterprise-grade, open source usage based billing infrastructure for AI and SaaS companies. It can be deployed in your own VPC, on-prem, or on Flexprice's managed cloud. For consumption:
Credits and Wallets stacks one-time, recurring, and promotional balances with deduction order, expiry, credit rollover, and top-ups.
Usage Metering puts the balance check in the request path, not a nightly job, under 60ms P99 to 1 million events a second.
Overage charges the card or blocks usage, with threshold alerts before a customer runs dry, and prepaid and postpaid share an account.
Feature gating by plan tier stops an expensive call before it runs, updated without a deploy.
Billing and Invoicing merges credits, usage, and subscriptions into one invoice, with margin per customer and model.
Same build: RBAC, parent-child accounts, contract versioning, four gateways.
"Our core product is not credits. We build ad analysis and generation technology, not billing infrastructure, and that is where my focus needs to be." - Kush Daga, Founding Engineer, Segwise.
Plans are flat and published, free at 100K events a month to $1,000 at 5M. Prepaid credits and the portal start at Scale.

AI Billing Is Not Easy, But Flexprice Can Make it Easy
AI Billing Is Not Easy, But Flexprice Can Make it Easy
2. Orb
Orb runs prepaid and postpaid credits with separate ledgers per pricing unit and pooling across parent-child accounts. Commercial terms are the constraint: quote-only, no published figure, no free tier, so a company still finding pricing fit pays enterprise rates. Closed source, Adyen-owned.
3. Lago
Lago is also open source and self-hostable, and the difference is enterprise scale. Prepaid credits, entitlements, RBAC, and real-time balances sit behind Premium, and outside it a balance resolves at invoice finalization.
4. Chargebee
Subscription management software built for plan-based and per-seat billing, hosted only. No real credit wallet and no native rollover credits, so prepaid AI consumption lands in custom code, at 0.80% of billing value.
What does consumption billing require from a metering system?
The balance must be authoritative in the request path, not the invoice.
The requirements that decide the build:
Read-your-writes, so concurrent calls can't spend the same credit.
Deduction order across stacked balances, as configuration.
Idempotent ingestion, since a retry must not double-deplete.
An event log the customer can inspect during a dispute.
How do the platforms compare on consumption billing?
From public docs.

Start with the first block. Three of these four gate real-time drawdown or lack it, which is what an AI credit product buys.
Frequently asked questions
What prepaid and credit options do AI consumption products need?
They need stacked balance types with a defined deduction order, per-grant expiry and rollover, auto top-ups, and an overage policy that charges a card or blocks the call. One flat balance covers a trial and breaks once you add promotional credits or per-feature grants.
How do consumption billing platforms price themselves?
Two ways, and they diverge fast. Flat per plan fixes your billing cost regardless of what you bill, how Flexprice prices at $500 and $1,000 a month. A percentage of billing value, like Chargebee's 0.80%, rises with every dollar collected.
Grant a test customer credits, spend them down through your real API path, and check the balance mid-period. See credit-based billing for AI apps and credit-based pricing software.
