To run a sync on Airbyte Cloud, you need to have credits. Airbyte credits are used to pay for Airbyte resources when you run a sync. If you have 0 credits, you won't be able to run the sync. Here's how you can purchase credits: 1. On the [Airbyte Cloud](
http://cloud.airbyte.com) dashboard, click
Billing in the navigation bar. 2. If you are unsure of how many credits you need, use the [Cost Estimator](
https://cost.airbyte.com/) or click
Talk to Sales to find the right amount for your team. 3. Click
Buy credits. 4. The Stripe payment page displays. If you want to change the amount of credits, click the
Qty 200 dropdown. The
Update quantity dialog displays, and you can either type the amount or use minus (
–) or plus (
+) to change the quantity. Click
Update. - Purchase limits: - Minimum: 20 credits - Maximum: 2,500 credits. To buy more credits or a custom plan, reach out to [Sales](
https://airbyte.com/talk-to-sales). 5. Fill out the payment information. After you enter your billing address, sales tax (if applicable) is calculated and added to the total. 6. Click
Pay. Your payment is processed. The Billing page displays the available credits, total credit usage, and the credit usage per connection. A receipt for your purchase is sent to your email. Credits expire after one year if they are not used. For more information, you can refer to the [Manage credits](
