For partners & resellers

You bring the merchant.
Duet runs the math.

If you sell to small businesses — POS resellers, accounting firms, church consultants, sports-org platforms — Duet is a clean product to refer. One link, one onboarding, and your merchant stops bleeding 3% to card fees.

Become a partner How Duet works

Why partners pick Duet

A product that closes itself.

A real economic argument

Most SaaS pitches are 'save time'. Duet's is 'keep dollars'. Your merchant nets ~$99.70 on a $100 card transaction instead of ~$97. That's a story that closes itself.

It plugs into Square — not rip-and-replace

Square merchants already have the rail. They don't have to switch processors, learn new software, or sign a long contract. Money still lands in Square.

Compliance is the platform's problem

You won't field state-by-state legal questions. Duet handles the disclosures on every invoice, payment page, and receipt. Legal in all 50 states.

Five-minute onboarding

Connect Square via OAuth, set the Dual Price %, send the first invoice. You can stand a merchant up between meetings.

Branded, not generic

The merchant's payment pages look like part of their own business — hosted on duetpay.io or embedded into their own site with a 3-line script.

Built for the verticals you serve

Print shops, non-profits, sports orgs, sign companies, body shops, churches. Public payment pages, donation widgets, QR codes, recurring giving.

The flow

From a link in your deck to a paying merchant.

1

Get your link

We issue you a unique referral link — duetpay.io/?ref=YOURNAME. Use it in pitches, decks, in-product nudges, mailers, QR codes.

2

Merchant lands

When a merchant clicks through, the marketing pages quietly mark them as referred — a 'Referred by YOURNAME' badge in the header, attribution carried through onboarding.

3

Five-minute setup

They connect Square, set their Dual Price %, send their first dual-priced invoice — without you in the room.

4

You get paid

You earn an ongoing share of Duet's platform revenue for as long as the merchant you referred is processing transactions. No flat per-merchant bounty — if they don't run volume, there's nothing to share. When they do, you do. Specific terms in your partner agreement.

Your link, live

Try it. Type your partner slug.

We attribute the merchant from the moment they land. The link itself is the entire integration — no SDK, no callback, no merchant action.

Partner FAQ

The partner questions.

Who's a good partner fit?

POS resellers, accounting and bookkeeping firms, church and ministry consultants, sports-org platforms, sign- and trade-association consultants. Anyone with a book of SMBs who use (or could use) Square.

How does revenue share work?

You earn an ongoing share of Duet's platform revenue for every transaction your referred merchants process — for as long as they're active. There is no flat per-merchant bounty; if a merchant signs up but never runs volume, nothing is owed and nothing is paid. Specific percentages and payout schedule are in your partner agreement.

Do I need to handle support?

No. Duet supports the merchant directly — onboarding, integration questions, day-to-day usage. You stay in the relationship as the referrer, not as the help desk.

Can I co-brand the experience?

For larger partners, yes. We can co-brand the onboarding flow and the merchant's payment pages can include a 'Powered by Duet, brought to you by Partner' line. Talk to us about scope.

What about compliance and contracts?

Duet handles the dual-pricing disclosures and the underlying Square app-partner integration. Your partner agreement is a standard referral arrangement — short, plain English.
