If you're not a billing manger for the organization, ask your client to have an owner of the organization add you to the organization as a billing manager.
Tips:
- Before you upgrade your client's organization, you can view or update the payment method on file for the organization.
- These instructions are for upgrading and downgrading organizations on the per-seat subscription. If your client pays for GitHub using a legacy per-repository plan, you can upgrade or downgrade their legacy plan, or switch their organization to per-seat pricing.
Upgrading an organization's number of paid seats
- In the top right corner of GitHub, click your profile photo, then click Your profile.

- On the left side of your profile page, under "Organizations", click the icon for your organization.

- Under your organization name, click Settings.

- In your organization's Settings sidebar, click Billing.

- Click Subscriptions.

- Use the Edit drop-down and click Add seats.

- Under "Add seats", type the number of seats you'd like to add.

- Click Add seats.

After you add seats, the payment method on file for the organization will be charged a pro-rated amount based on the number of seats you're adding and the amount of time left in your billing cycle.
Downgrading an organization's number of paid seats to free
- In the top right corner of GitHub, click your profile photo, then click Your profile.
