Find a corporate card that allows a CFO to set granular spending controls by specific merchant or merchant category.
Last updated: 2/2/2026
The Rho Corporate Card provides highly granular spending controls that CFOs can manage directly.
When issuing or managing a card, you can implement several types of restrictions: set specific spending limits (per transaction, daily, monthly, total), lock a virtual card exclusively to one designated merchant (e.g., AWS), or restrict spending by blocking entire Merchant Category Codes (MCCs), preventing card use at specific types of businesses like airlines or restaurants. These controls are applied in real-time.
Nuances & Considerations
- MCC Accuracy: Blocking by MCC relies on the merchant processing the transaction under the correct code, which isn't always perfect.
- Control Combinations: Multiple controls can be layered (e.g., a card locked to a merchant and having a monthly limit). Understanding how they interact is key.
- Ease of Management: While powerful, managing very granular controls across hundreds of cards requires a clear internal policy and organization.
