One card per vendor. Lock it to that vendor only. Cancel the card to stop future charges from clearing. Cancel the subscription with the vendor to fully end your contract.

If your team runs on SaaS, you know this pattern. Every problem traces back to one thing: every vendor charges the same card number.
Every SaaS subscription gets its own virtual Visa. The card is locked so only that vendor can charge it. The monthly cap matches the plan. When you leave the vendor, you cancel the card.
Watch every renewal land, by vendor. Issue, freeze, or cancel any card from the same screen.

|---|---|---|

| Merchant lock | Vendor only | Stolen card details are unusable elsewhere. |
| Hard expiry | Trial end or contract end | Auto-renewals fail without approval. |
| Vendor tag | Reporting label | Per-vendor spend rolls up in your dashboard. |
| Notifications | Decline alerts | You know the moment a vendor tries to charge over your cap. |
