“The Polar team treated us like a design partner, not just a customer. They built features we needed on tight timelines and worked collaboratively to resolve issues. That’s rare.”

the moment your model streams it
Tokens, agent runs and GPU seconds flow through live meters and land on the invoice, priced however you sell.
Every call, token and GPU second your users consume, recorded the moment it happens.
Raw events roll up into a live meter for every customer, updated in real time. No batch jobs, no lag.
Usage lands on the invoice and settles at the end of every cycle, without any manual reconciliation.
subscriptions, credits and usage together
Combine a base plan, prepaid credits and metered usage on one product. Polar draws credits down first, bills the overage and settles it at the end of the cycle.

for every customer, not just on average
Attach the inference cost to the events you already send. Polar collects the revenue, so it can put the two side by side and show the customer burning more than they pay.

a first look at our new usage billing engine
Billing as code, zero-latency checks and simulations before you ship a price. Read how it works, and join the first teams building on it.
“The speed at which Polar is executing on the financial infrastructure primitives the new world needs is very impressive.”
“Polar's Python SDK and Webhook infrastructure made our billing integration straightforward. It gave us production-ready billing in hours, not weeks. It's rare to find a vendor that moves this fast.”
“I've joined Polar as an advisor! I think it benefits everyone for devs to have more options to get paid to work on their passions, to support upstreams, and for users to have more confidence/transparency in the software they're supporting/purchasing.”
“Polar has been giving us the high attention support of a startup, with an enterprise-level product and service.”
