Need to pay one vendor invoice, or cover a one-off purchase for a team member who is traveling? You can create a virtual card, fund it with the exact amount of the purchase and send the card details straight to the merchant. No plastic card, no shared company card number and no surprise charges.
Coming soon:A true single-use card that closes itself automatically after one payment. Until then, use the setup below to get the same control today.

How to set up a single use card today

Instead of giving the card a high limit, put the dollar value of the purchase on the card. The card can only spend what you put on it, so it behaves like a single use card.
1
Order the card
2
Set the expirationChoose the shortest expiration that covers the purchase. See Expiration terms below.
3
Fund the card with the exact amountUnder Funding, select Add funds to card and enter the exact purchase amount. Leave the recurring funding frequency off, and leave Use Auto Card Funding off so the card can’t pull more from your business balance.
4
Lock the card to the merchant (Vendor cards only, recommended)Check the vendor locking box and select the merchant. The card will only work with that merchant, which prevents unauthorized charges and makes reconciliation easier
5
Send an invitation to the merchant (Vendor cards only)This step applies to Vendor cards. Team Member cards can’t be sent to a merchant — the Cardholder uses the card details themselves.From the Card details page, hover the card image and click Send to vendor to email a secure invitation. The merchant follows the link to collect the card number, expiration date and CVV, then charges the card to settle your bill. The link expires as soon as it’s opened, or after 30 days. See How to send card to vendor
6
Close the card when the payment clearsOnce the transaction settles, close the card so it can’t be used again. See How to Close a Card
Note:Sending a card to a vendor requires an administrator with Funding of Cards and View Card Usage permissions and multi-factor authentication enabled.

Expiration terms

PEX expiration terms are flexible. On the card order form you can choose:
  • 1 month
  • 3 months
  • 6 months
  • 1 year
  • 3 years
  • 4 years
  • 5 years — the longest term available
For a one-time payment, 1 month is usually enough. Give yourself a longer term when a vendor bills on a delay or when the same card will cover a multi-month engagement.
Note:Custom card expiration depends on your plan. If the Card expiration dropdown isn’t on your order form, contact adminsupport@pexcard.com

When to use a single use card

  • Bill payments. Pay one vendor invoice without handing out a reusable company card number. See Bill Pay: Create & Send a Bill Payment
  • Team member travel. Fund a flight, a hotel or a client dinner for an employee on the road
  • Events and conferences. Cover registrations, booth fees or catering for a single event, with a card that expires soon after
  • One-off suppliers. Buy from a merchant you don’t expect to use again

Recurring spend instead?

If the same charge repeats every month — software and SaaS subscriptions, insurance premiums, ad spend, utilities — create a vendor card with recurring funding rather than a single use card. Set a funding frequency (or auto card funding with a time-based spend limit) and a longer expiration term so the card keeps paying the bill.

Single use card FAQs

  • Not yet. Fund the card with the exact purchase amount so nothing is left to spend, then close the card once the transaction settles. Automatic closure after one payment is coming
  • The transaction is declined for insufficient funds. If the final amount can vary — a hotel incidental hold, for example — add a small buffer, or set a time-based spend limit instead. See What are the reasons for card declines?
  • Vendor cards are free and don’t count toward your allotted card accounts. Team Member cards do count
  • Team Member virtual cards can be added to a digital wallet, so they work for in-store purchases while traveling. Vendor cards are online-only. See Adding a PEX Card to a Digital Wallet
  • Yes. Fund it again with the next exact amount and send it to the merchant, or leave recurring funding on if the charge repeats
