Checkflo is a solid starting point for small businesses sending a few dozen checks a month through QuickBooks. But when your payment volume grows, your compliance requirements tighten, or your CFO starts asking harder questions — you need infrastructure, not an app.
SmartPayables was built from the ground up for exactly that inflection point.

Where SmartPayables Wins
1. You Keep Your Formats
Venture-backed apps often force you into their templates. SmartPayables supports fully custom HTML check layouts, so your checks look the way your bank, your brand, or your client expects — not the way an app developer decided.
2. Positive Pay That Works at Scale
Positive Pay isn’t just a checkbox for us. Every check run generates a Positive Pay file automatically, protecting your accounts against altered or fraudulent items. When you’re running 10,000+ checks a month, that’s not optional.
3. White-Label for Financial Institutions
Banks and credit unions use SmartPayables as silent infrastructure. Your customers never know we’re involved. Checkflo does not offer white-label services for financial institutions.
4. A Real Human on Your Account
You get a named account representative and direct access to our development team. Not a ticket queue. Not a chatbot. When something needs to get done, you have a person to call.
5. No Ceiling on Volume
SmartPayables operates industrial-scale print and mail facilities. Whether you’re sending 500 checks or 500,000, our infrastructure scales with you. There are no throttles, no caps, and no surprises.
