Why month-end takes so long

Step 1 — Connect every account

Start with the job, not the person

Issue a card for a purpose — software, travel, ads — instead of for an employee. Limits then describe what the money is for.

Set limits that match reality

Monthly caps work for subscriptions, while per-transaction caps suit travel. Choose by how the spend actually behaves.

Use merchant rules

Lock a card to one merchant or category and most fraud and most policy mistakes disappear at the same time.

Alert on exceptions only

Notify owners when something unusual happens, not on every swipe, so alerts stay worth reading.

💡

Tip: freeze virtual cards when a project ends rather than deleting them, so you keep the history.
