Quizlet does not accept Purchase Orders. You can purchase a single upgrade, or group of upgrades, by credit card on our website — or submit a request to pay by check for two (or more) Quizlet Plus or Teacher upgrades.
If you want to pay for a single Quizlet upgrade by credit card on behalf of another person, you can have them email you an invoice so you can complete a purchase on their behalf.
