Pricing model
How transaction pricing works
Commet charges 4.5% + $0.40 on every successful transaction. Payment processing is already included in that fee — there is no separate processor bill and no markup on top of it.
You only pay when a payment settles. Declined cards and failed attempts cost nothing, refunds are free, and there are no setup fees, monthly fees, or minimums.
Two payment provider costs are passed through without markup: cards issued outside the US add 1.5%, and disputes cost $15.00 each.
What you pay as you grow
| Monthly revenue | Assumption | Monthly fee | Effective rate |
|---|---|---|---|
| $1,000 MRR | 20 customers at $50/mo | $53.00 | 5.30% |
| $10,000 MRR | 100 customers at $100/mo | $490.00 | 4.90% |
| $100,000 MRR | 400 customers at $250/mo | $4,660.00 | 4.66% |
One successful charge per customer per month. The fixed $0.40 weighs less as your average transaction grows.
Merchant of Record
What the fee covers
Commet is the Merchant of Record: the legal entity that sells your product to the end customer. One transaction fee funds the entire billing and payments operation.
Global card payments
Accept card payments from customers worldwide — Visa, Mastercard, and American Express — charged in their local currency across 20+ markets.
Local payouts in 112 countries
Commet supports businesses in 112 countries and pays out in your local currency, with no conversion surprises.
Tax calculation and remittance
Sales tax and VAT are calculated on every checkout. As Merchant of Record, Commet collects and remits them on your behalf.
Compliance and liability
As the seller of record, Commet carries the regulatory burden of each transaction so your entity does not.
Refunds and disputes
Refunds are processed for free. Disputes are handled through the payment provider at cost ($15.00), with no markup.
Billing infrastructure
Subscriptions, usage-based and metered billing, credit packs, seats, and balance accounts are built in — not a paid add-on.
Automated invoicing
Invoices are generated and delivered automatically for every charge, with a customer portal included.
SDK, API, and webhooks
Type-safe SDKs, a full REST API, and webhook events come with every account, with no limits tied to pricing tiers.
Compare
One fee instead of a billing stack
The usual setup for a SaaS that charges globally is a payment processor, a subscription billing tool on top of it, a tax automation service, and the engineering time to keep all three in sync with webhooks. Each layer bills you separately, and you are still the Merchant of Record carrying the tax liability.
Commet collapses that stack into a single transaction fee: payments, billing logic, taxes, and payouts run in one system, and you only pay when you get paid.
Pricing FAQ
How does Commet pricing compare to a traditional payment processor plus billing stack?
A typical stack combines a payment processor's transaction fee, a subscription billing platform's percentage or monthly subscription, and a separate tax automation service. Commet's 4.5% + $0.40 covers all three layers in one fee, including Merchant of Record tax handling. See the Stripe Billing comparison for a detailed breakdown.
Are there monthly fees or minimums?
No. There are no setup fees, monthly fees, tiers, or minimums. The only cost is 4.5% + $0.40 per successful transaction, so you pay nothing until you start charging customers.
What counts as a successful transaction?
A payment that is captured and settles. Declined cards, failed attempts, and abandoned checkouts are never charged, and building and testing in the sandbox environment is free.
How do refunds affect fees?
Refunds are free. Commet does not charge an additional fee to process a refund, and as Merchant of Record it handles the refund flow with your customer.
Do you charge more for international cards?
Cards issued outside the US add 1.5%. This is a payment provider cost passed through without markup. Customers are still charged in their local currency, and you receive payouts in yours.
What does a dispute or chargeback cost?
Disputes cost $15.00 each — the payment provider's fee passed through at cost, with no markup from Commet.
Is tax handling included in the fee?
Yes. As Merchant of Record, Commet calculates tax at checkout and collects and remits it on your behalf, so you don't need a separate tax automation subscription or your own tax registrations.
Which payment methods does Commet support?
Commet processes card payments — Visa, Mastercard, American Express, and other major networks — charged in the customer's local currency. Bank debits and local payment methods are not currently supported.
