Brionic Payments
Already on Square?
Start accepting crypto in minutes
Keep selling on Square and add XRP, XLM, USDC, and RLUSD invoicing on top. Sync your existing Square customers in one click and bill them in crypto: no chargebacks, and no percentage cut, just a flat monthly plan.
Read-only · non-custodial · funds settle to your own wallet
From Square to crypto in three steps
No migration and no double data entry. Bring your customers with you.
Connect Square
Paste a read-only Square access token. We only read your customer directory, nothing in Square is changed.
Sync your customers
One click imports every Square customer into Brionic, matched by email. Re-sync any time to pull in new ones.
Send crypto invoices
Bill those customers in XRP, XLM, USDC, or RLUSD. They scan a QR to pay, and the invoice reconciles itself on-chain.
Everything Square doesn't do
Keep 100%, not 2.6%+
Crypto invoices settle with no percentage cut. You pay a flat monthly plan, not a fee on every sale.
No chargebacks
Crypto payments are final. Nothing gets clawed back weeks after you've done the work.
Global by default
Get paid by customers anywhere at any hour, with no card network, border, or banking hours in the way.
Your customers, imported
Sync your whole Square customer directory so you can start invoicing the people you already serve.
Non-custodial
Payments settle directly to a wallet you control. We never hold your funds.
Passwordless & private
Sign in with passkeys, run no third-party trackers, and keep customer data minimal.
