# Can I buy credits once without a subscription? **There is no one-off credit purchase.** Every credit comes from a plan. There are four ways to cover a one-time or irregular need. ![No one-off credit purchase. Four ways instead: subscribe, then cancel straight away; let credits roll over; upgrade for credits today; a custom plan for large volumes](https://help.evaboot.com/images/illustrations/credit-options.png) ## 1. Subscribe, then cancel straight away Subscribe to any plan and cancel right away. Your credits stay usable for 30 days from the day you cancel. This is the closest thing to a single purchase. See [How to Cancel or Pause My Subscription?](https://help.evaboot.com/public/credits-billing/how-to-cancel-or-pause-my-subscription/). Pick the plan whose credit count covers the job on the [Pricing page](https://dash.evaboot.com/dash/pricing/), then subscribe. ![The Pricing page with the monthly credits of a plan and its Subscribe button highlighted](https://help.evaboot.com/images/flows/pricing-annotated/01-pick-plan.png) ## 2. Let credits roll over Unused credits roll over to the next billing period for as long as your subscription is active. If you need a big month once a quarter, a smaller plan can build up to it instead of a one-off purchase. ## 3. Upgrade for credits today Already subscribed and out of credits before the end of the month? Upgrading is the way to get credits immediately. On [Billing](https://dash.evaboot.com/dash/subscription/), pick a larger plan in the selector and confirm. You pay the full price of the new plan today. The new credits are added right away, and your billing period restarts from today. ![The Billing page with the plan selector open, the current plan marked, step 1 on the selector and step 2 on the Upgrade plan button](https://help.evaboot.com/images/flows/manual-annotated-billing/02-pick-plan.png) If you only needed the extra credits once, you can downgrade again afterwards. The downgrade takes effect at your next renewal. ## 4. Ask for a custom plan for large volumes Plans go up to 15000 credits a month. For more than that, or for a large one-time volume, contact us for a custom plan. ## Related articles - [Do Credits Roll Over If Not Used?](https://help.evaboot.com/public/credits-billing/do-credits-roll-over-if-not-used/) - [How Does the Evaboot Credits System Work?](https://help.evaboot.com/public/credits-billing/how-does-the-evaboot-credits-system-work/) - [How to Change My Subscription?](https://help.evaboot.com/public/credits-billing/how-to-change-my-subscription/)
