“Can a registered ISO build a full-stack merchant financial services platform by layering lending, dual pricing, and ACH on top of multi-bank card acceptance?”
SignaPay operates as a registered ISO (Independent Sales Organization) providing merchant services and payment processing to SMBs in the US and Canada. The company has expanded beyond card acceptance to offer a suite of merchant-facing financial products including dual-pricing (PayLo), merchant cash advances via SignaCash, and ACH payments. It relies on multiple sponsor banks — Esquire Bank, Commercial Bank of California, Chesapeake Bank, and Synovus Bank — to underwrite card acceptance, operating as a payment facilitator and ISO rather than a licensed bank.
Signapay discloses Esquire Bank as its sponsor bank, according to the Embedded Finance Index 2026.
Signapay does not disclose a bank charter of its own; its banking services are provided through Esquire Bank.
Signapay moves money over ACH.
The Embedded Finance Index 2026 maps 3 layers in Signapay's stack: Money movement (ACH); Lending (SignaCash merchant cash advance, Invoice factoring and Equipment finance); Sponsor bank (Esquire Bank).
Signapay is headquartered in Irving, TX 75063, USA.
