Collect every seat tier on a single invoice
Invoice editor, viewer, and admin seats on one USDC bill — add a new role without new billing code — and every payment credits your Paymos balance.
Where design SaaS revenue gets shaved by seat models and reseller margins
Why does a three-tier seat plan need bespoke billing code?
Four ways the card rail and reseller stack shave design-tool revenue.
A three-tier seat model breaks single-quantity billing
Design tools charge different rates for editor, dev, and viewer seats, often with viewers free. An agency with a dozen designers, thirty viewers, and a handful of dev-mode users needs three separate line items wired into one subscription. A card-billing "quantity" field assumes one seat tier per subscription. Engineers end up writing bespoke proration logic and custom invoice components every time a new role appears — none of which moves the product forward.
Resellers take a heavy margin on agency rollups
Creative-suite licences get resold through reseller programs at a steep margin to agencies buying dozens of seats. The agency wants a single bill, the subcontractors want individual access, and card-billing isn't built for "agency buys fifty seats, distributes credentials to subcontractors." Either you eat the reseller margin or you build the rollup logic yourself — neither is free.
International designers churn at signup where card coverage doesn't reach
Indie design marketplaces draw designers from Argentina, Ukraine, parts of MENA, and Southeast Asia — exactly the regions where card processors don't onboard merchants and local cards get declined for cross-border SaaS. The designer sees the checkout, picks a card, gets declined for "issuer unavailable," and bounces. The signup never happens, and there's no recovery email because there was no customer record to email.
Asset marketplaces pay a per-account fee for every vendor on file
Font foundries, 3D asset stores, animation libraries, and stock platforms run a marketplace model — designer pays vendor, platform takes a cut. The standard marketplace-payments setup charges a monthly fee per connected account plus a cut on transfers. A marketplace with thousands of vendors pays a large monthly bill in account fees alone — before any of those vendors have made a single sale.
How one clean invoice fixes seat and rollup billing
What changes when seats settle as one stablecoin payment?
Four things that go right when design-tool billing leaves the card-and-reseller stack.
One invoice with explicit per-tier line items
The seat invoice settles as editors plus dev seats plus free viewers as one amount on a single Paymos invoice. No bespoke seat math, no custom billing component glued to your admin API. The customer sees the breakdown, your accounting sees the breakdown, and the customer pays one amount that credits your Paymos balance on confirmation — a paid invoice that can't be reversed.
An agency rollup pays one invoice and distributes seats internally
A multi-seat agency rollup pays one invoice, then distributes seat credentials to subcontractors through your existing admin panel. No per-account marketplace fee, no reseller margin sitting between you and the agency. The agency is one customer to Paymos; the subcontractors are one customer to your admin. Clean separation, and the payment is final the moment it clears.
International designers pay the same as a domestic one
An Argentine designer signs up, pays in stablecoins, and is done in under a minute. No "issuer unavailable" decline, no FX surcharge on a local card converting to dollars, no country gap. The wallet works wherever the designer is — Buenos Aires, Lagos, Kyiv, Manila — and the receivable lands in the same treasury wallet as your domestic customers, with no processor able to freeze you for serving them.
No sub-merchant accounts — the per-account fee disappears
A marketplace-payments setup charges a monthly fee per connected account just to keep a vendor on file. Paymos has no sub-merchant model at all: buyers pay your platform treasury directly, and dormant vendors cost nothing because there are no accounts to maintain. The honest boundary: Paymos doesn't run marketplace-style splits or vendor payouts — you settle with vendors on your own rail. What it removes is the per-account fee on the money coming in.
How design platforms wire Paymos in
Which integration fits how you bill seats?
Three ways to collect seat and asset revenue in stablecoins.
Host-to-host API — composite seat invoices from your admin
Your admin API computes the seat count per tier each period. The host-to-host API lets you post the composite total as one invoice with explicit per-tier lines, hand it to the customer's wallet, and watch settlement. When the transfer confirms, a signed HMAC-SHA256 webhook closes the seat invoice in your books without manual matching. Your seat math stays in your admin; Paymos handles the settlement leg.

Hosted Checkout — self-serve seats and asset purchases
For self-serve seat plans and marketplace asset purchases, create a Paymos invoice and redirect the buyer to a hosted page, where they pay from their wallet and return. No payment screen to build, and international buyers don't hit the card-decline wall. The same flow handles a single editor seat and a single asset purchase identically.

Payment Links — agency rollups and enterprise deals
For an agency rollup or enterprise seat deal, generate a Payment Link for the rollup total with your PO or contract reference attached as the order reference — the seat breakdown stays in the quote your own system issues. The agency pays from one wallet, your receivable closes on confirmation, and the agency distributes seats to subcontractors through your admin — no per-account fee, no reseller margin.

Which design models run cleanly on a wallet rail?
Four flows from real design setups — editor seats, agency rollups, asset marketplaces, prototyping tools.
Editor seats — multi-tier team plans
The standard editor-seat plan settles in stablecoins each period. Your admin API computes the seat count and issues the invoice through Paymos; the customer pays the prorated amount from their wallet at period close. The payment confirms in seconds and credits your Paymos balance — and on a large team plan, a paid invoice that can't be reversed is one less renewal to chase.
Agency rollups — large seat deals with internal distribution
Design agencies and studio rollups want one invoice, one payment, and the freedom to distribute credentials to subcontractors without paying reseller margins. The agency pays a single invoice, your admin lets the agency manage subcontractor seats internally, and Paymos handles the payment leg — final the moment it clears.
Asset marketplaces — fonts, 3D, animation, stock
Font foundries, 3D asset stores, animation libraries, and stock platforms run buyer-side checkout through Paymos: the buyer pays for the asset, the funds credit your platform's Paymos balance, and international buyers don't hit the card-decline wall. There are no sub-accounts, so the per-vendor fee goes away. Vendor payouts themselves stay on your existing rail — Paymos handles the money coming in, not the splits going out.
Prototyping and motion — per-seat and per-project
Prototyping and motion-graphics tools sell per-seat or per-project subscriptions to in-house teams and freelancers. The economics are the same as the editor tier but the audience skews more international, so stablecoin checkout cuts the international decline rate — the designer pays from their wallet, and the payment lands and stays final.

Honest disqualifier
When NOT to use Paymos for design tools
Four cases where staying on your current setup is the right call.
You need automatic marketplace splits and vendor payouts
If your core requirement is splitting each sale between platform and vendor and paying vendors out automatically, that's exactly what a marketplace-payments product does and what Paymos does not. Paymos removes the per-account fee on inbound money, but it won't run the payout side. If automatic splits are non-negotiable, keep the marketplace-payments setup for that leg.
Every customer you have already pays happily by card
When the whole book is domestic teams whose cards clear on the first try, a wallet checkout solves a problem you don't have. This rail earns its place through international designers, per-tier invoices, and vanished per-vendor fees — if none of that describes your revenue, the migration buys you little.
Your team plans depend on subscriptions renewing themselves
A design subscription on a saved card quietly renews every month; a stablecoin payment has to be sent by the customer each time, because Paymos cannot pull funds from anyone's wallet. For monthly team plans sold on convenience, that extra action costs renewals. Put annual plans, agency rollups, and marketplace purchases on the wallet rail — one deliberate payment each — and keep monthly autopay on cards.
Your buyers won't open a wallet for a small seat purchase
For a low-priced single-seat purchase to a buyer who has a card and no wallet, asking them to switch to a wallet adds friction the conversion can't afford. Offer the wallet as an option, not a default, and watch the conversion split — at a small seat price, card UX often wins for the domestic buyer even where the cost case favours stablecoins.
