Ramp has virtual card functionality (and physical cards for employees). You'll want to spin up a virtual card for each vendor you use with Ramp, and you can even restrict (lock) these cards to a specific merchant.
This is core to what makes Ramp powerful, and honestly the reason we care so much about expense management even as a small team.
A while back, Alex caught two charges on a statement that didn't make sense, one at Home Depot, one at Walmart. The card was only on file with our accountant, so we knew immediately something was wrong. We froze it, called the office, and it turned out an employee who'd been there 15 years had been stealing card numbers. She was caught, but the whole thing stuck with us.
If you take one thing away from this review, it's this: when you run everything through one shared card, a problem anywhere becomes a problem everywhere.
With Ramp, our engineer has a dedicated card for his OpenAI subscription. If that ever gets compromised, we cancel one card, we don't spend a weekend updating payment details across every tool in the stack.
You can also lock cards to specific merchants, set daily/weekly/monthly/one-time limits, and cap free trials so you never "accidentally" get charged when a subscription renews. Or spin up a one-off vendor card and close it immediately after.
As your team grows, you can layer in approval workflows, assign roles, and build policies around spend. It's flexible enough for a finance team, but simple enough that as a small team, you won't feel buried in configuration.
