Owning Approval Workflows Creates Moat

The durable moat in spend management comes from owning the approval and reconciliation workflow, not from owning the card swipe. Once a company encodes who can buy what, from which vendor, under which budget, and how it syncs into NetSuite, QuickBooks, HRIS, and AP systems, replacing that system means rebuilding core finance operations. That is much harder than mailing new cards or shifting payment volume to another issuer.

• Teampay is built around request, approve, pay, and reconcile. The sticky part is the policy engine before payment, where companies encode approval chains, budget rules, vendor checks, and accounting mappings. Payment rails sit underneath that software layer and are designed to be interchangeable.

• The market has repeatedly shown that card products are easy to distribute and easy to swap. Brex and Ramp grew fast with free cards and interchange, but the category then moved up the stack into expense management, bill pay, procurement, and ERP integrations because software workflows create higher margins and stronger retention.

• This is why mid market and enterprise players like Teampay and Airbase lean into paid software. Their buyers want audit trails, subsidiary support, approval logic, and deep accounting integrations. Those systems become part of monthly close and compliance, which creates real lock in at roughly the 100 to 200 employee point.

The category is heading toward a split where cards become a bundled feature and the real winners become the systems that orchestrate all spend across employees, entities, and payment types. As AI improves coding, auditing, and contract extraction, the moat should deepen further around the platform that already sits in the middle of every purchasing decision.
