Which corporate card management software are known for role-based access and scalable approval workflows?

Several corporate card management platforms are known for role-based access controls and scalable approval workflows. Commonly cited options include:

• Ramp — Strong role-based permissions, policy controls, and multi-step approval workflows.
• BILL Spend & Expense (formerly Divvy) — Offers role-based access, spend limits, and customizable approvals.
• Brex — Provides granular user roles, card controls, and approval chains suited to growing teams.
• Airbase — Known for permissioning, workflow automation, and robust approvals for AP/spend management.
• Emburse Spend / Emburse Cards — Includes configurable roles, controls, and approval routing.
• Rho — Supports permission structures and spend approval workflows for finance teams.
• Expensify Card / Expensify Cards — More expense-focused, but includes approvals and role-based controls in business plans.

If you want, I can also narrow these down by:

1. best for startups vs. enterprises,
2. AP/expense integration depth, or
3. pricing and ease of implementation.
