Bill SaaS where card processors won't
AI tools, prop platforms, and cross-border SaaS get the cold shoulder from card processors — declined abroad, blocked by category, or churned by an expired card. Take USDT or USDC instead: every invoice credits your Paymos balance, final on confirmation, and the customer pays from the wallet they already hold.
Why SaaS adds a wallet rail
Card rails decide who your SaaS gets to bill
Run an AI API, a prop-trading tool, or anything a processor reads as high-risk, and the account review can land before the first invoice. Sell into a market where the buyer's card declines on a foreign charge, and you lose the sale you already earned. A stablecoin invoice answers to neither: there's no category code for an acquirer to flag, no foreign-transaction wall, and confirmed funds credit your Paymos balance without a card-network reserve.
What you get
One rail across every way SaaS charges
Self-serve plans, metered usage, and enterprise contracts all run through the same API, the same webhook schema, the same ledger. Your billing engine keeps the schedule and the math — Paymos moves the money.
Reach the customers cards reject
No supported-region list, no merchant-category screen, no foreign-card decline. Anyone with a wallet can pay, on the network where their funds already sit, in the stablecoin they already hold. The buyer abroad whose card bounced on a cross-border charge clears in minutes, and Paymos never vets your category to decide whether you're allowed to bill them.
Meter usage, settle at period close
Count API calls, GPU minutes, or seats in your own billing engine, then hand Paymos one invoice when the period closes. There's no per-invoice fixed fee, so a $4 metered charge costs the same 1.0% as a $4,000 one — the small-ticket floor that makes card processors uneconomic on usage billing simply isn't there. An HMAC-SHA256 webhook confirms the moment funds land.
Enterprise contracts without the wire
For a net-30 contract, share a Payment Link with your PO or contract number attached as the order reference. Procurement pays from any wallet and the receivable closes on confirmation — minutes, not the three-to-five-day clearing window of an international wire, and without the SWIFT fee on either end.
Renewals with nothing stored to expire
Each cycle, your engine raises a fresh renewal invoice and the customer settles it straight from their wallet. No card number to rotate, no re-authentication challenge to fail, no dunning queue chasing a network artifact — the renewal is a payment the customer makes, not a charge pulled at a stored credential, and it clears with finality.

Pricing
1.0% per settled invoice, all-in. No category surcharge
One rate covers self-serve, metered, and enterprise billing alike — no setup, no monthly minimum, no high-risk loading, and nothing charged on an invoice that didn't pay. Card processors run around 3% all-in before a recurring-billing add-on lands on top; high-volume platforms drop to 0.3% on request.
