Editorial
The best usage-based pricing software for AI companies in 2026 is whichever platform meters tokens per model, holds a credit balance a request can check in real time, and puts usage, credits and a subscription on one invoice. Most platforms clear one or two. Flexprice clears all three, and we build it, so test that claim against the criteria below rather than take it.
Key Takeaways
A platform that can't hold a real-time credit balance forces you to build a second system in front of it. Segwise tried in-house for 3 weeks, then shipped on Flexprice in 3 days.
Per-model cost attribution tells you which customers are profitable, and Metronome doesn't track AI cost per model per customer.
Two of the platforms on most shortlists now belong to a payments company, so independence is a criterion: Stripe bought Metronome in January 2026 and Adyen closed its Orb acquisition on July 1, 2026.
Flexprice ships every feature in its OSS tier under AGPL-3.0, including RBAC and parent-child accounts, while Lago gates on-prem, RBAC and SOC 2 Type II behind Lago Premium.
What's the best usage-based pricing software for AI companies in 2026?
There isn't one. There's a best platform per criterion, and the credit wallet eliminates the most vendors before price ever comes up. Flexprice clears every criterion below, which is why it's on our own shortlist, and since we build it you should check that rather than accept it.
The rest of the market splits on three things worth testing yourself:
Whether credits are a real balance. A per-account wallet with recurring grants, rollover and expiry behaves nothing like a credit note that offsets an invoice.
Whether per-model AI cost is published at all. Most vendors document metering depth and say nothing about cost attribution per model per customer.
Whether the fee tracks your revenue. A percentage of billing volume grows even in a quarter when your pricing doesn't change.
The table further down carries the detail per vendor, with a "Not published" cell wherever the documentation doesn't answer

What criteria decide usage-based pricing software for an AI product?
The criteria run in this order, and the credit wallet eliminates the most vendors:
Credit wallet. Your product has to answer "does this account have balance left?" before a request runs, in milliseconds. Fail this one and you build a second system in front of the billing platform. Segwise built that in-house for 3 weeks, then shipped on Flexprice in 3 days.
Per-model cost attribution. This tells you which customers make you money. Charging GPT-4 differently from GPT-4o should come out of one event stream filtered on metadata. When a platform wants a schema per model variant, every model you ship becomes a billing change.
One invoice. Plenty of platforms handle credits, usage and subscriptions. Far fewer land all three on one document.
Deployment. One question settles it: can this run inside our infrastructure? Teams tend to hit that in month four of a sales cycle, not week one.
Cost structure. Everyone checks this first and it matters least. Stripe Billing takes 0.7% of billing volume, so $2M a month costs $14,000 for the same software.
How do AI companies price per token, request, or seat?
AI companies charge per token, per request or per seat, and most run two of the three. Each one has a specific failure point:
Per token. Maps cleanly to your cost and badly to customer value. I've yet to meet a buyer who could forecast a token bill.
Per request. Forecastable until two models cost different amounts to serve, then one price per call eats the margin on the expensive one.
Per seat. Breaks when one seat drives a hundred times the inference of another.
Credits sit on top of all three, giving the customer one number to watch and you room to reprice the unit underneath. That's why teams who get metering LLM token usage right tend to buy a wallet the same quarter.
Which usage-based pricing software is most flexible on pricing?
The platforms buyers ask us about line up like this on the axis that splits them. This table skips events per second, because we've covered throughput and deployment separately.
Platform | Credit wallet | Per-model AI cost tracking | Usage, credits and subscription on one invoice | Deployment | Cost structure |
|---|---|---|---|---|---|
Flexprice | Yes, recurring grants, rollover, auto top-ups, stacked deduction order | Yes, per customer per model | Yes, plus one-time fees | Cloud, self-hosted or on-premise, AGPL-3.0 | Flat, free tier at 100K events a month |
Orb | Yes, prepaid and postpaid | Not published | Not published | Cloud only | Quote-only, priced on billings plus events |
Metronome | Not published | No | Not published | Cloud only | No public pricing |
Lago | Yes, prepaid and recurring, capped at five wallets per customer | Not published | Not published | Self-hosted AGPLv3, on-prem inside Lago Premium | Community free, Premium quote-only |
Chargebee | No, promotional credits and credit notes only | No | Subscription-first, usage as an add-on | Cloud only | 0.80% of billing value, or $99/mo plus 0.65% |
Stripe Billing | No recurring or rollover grants | No, separate schema per model variant | No credit pooling or committed usage | Cloud only, requires Stripe Payments | 0.7% of billing volume |
How does Flexprice handle AI usage-based pricing?
Full disclosure, we build Flexprice, so check every number yourself. Flexprice is enterprise-grade, API-first billing infrastructure, built by engineers for engineers, open source and self-hostable. Enterprise and open source at the same time, not one growing into the other.
Here's what clears each criterion above:
Usage Metering ingests events in real time from APIs, microservices, webhooks and warehouses. Every event carries an
event_idthat is the idempotency key, so a retried request counts once.Credits and Wallets holds prepaid and postpaid balances with recurring grants, rollover, stacked credit types with a custom deduction order, and auto top-ups.
Billing and Invoicing tracks AI cost and margin per customer down to the model level.
Enterprise: SOC 2 Type II, on-premise deployment, RBAC, parent-child accounts, contract versioning, ramped contracts, 99.99%+ uptime, multi-currency across Stripe, Razorpay, Moyasar and Nomod.
Open source: AGPL-3.0, 3.5K+ GitHub stars, 61+ contributors, every feature in the OSS tier including RBAC and parent-child accounts.
Scale: 20B+ events a month, 60K+ events per second, under 60ms P99, 100+ customers including Simplismart, Segwise and Vapi.
TestZeus took the full integration live in 3 days with one engineer. Where we're the wrong answer: two or three flat plans with no metered dimension and no credits. Flexprice is more infrastructure than that needs.
Frequently asked questions
How do you meter LLM usage for pricing and billing?
Emit one event per model call carrying the model name, input tokens, output tokens and a unique event ID, then price each model off that stream using the event metadata. A new model then needs a price, not a new schema.
How much integration effort do AI usage billing tools take?
Days when the platform ships wallets and entitlements, months when you build them yourself. TestZeus went live in 3 days with one engineer. Segwise spent 3 weeks on credit-based pricing in-house before shipping on Flexprice in 3 days.
Can I self-host usage-based pricing software for an AI company?
Yes, on two of the six. Flexprice and Lago both ship self-hostable AGPL-3.0 builds, though Flexprice ships every feature in the OSS tier while Lago gates on-prem, RBAC and SOC 2 behind Lago Premium. Orb, Metronome, Chargebee and Stripe Billing are cloud only.
Answer two questions before you open another pricing page: does a request in your product need to check a credit balance before it runs, and do you need cost per model per customer? Those cut this list faster than any feature matrix, and our free tier covers 100K events a month.
