A personal account, which is on the Hobby plan by default, cannot be upgraded to a paid plan. If you would like be on a paid plan such as Pro or Enterprise, you will have to create a Vercel team. For Enterprise inquiries, please contact our sales team.
For more information on our Hobby, Pro, and Enterprise plans, please check out our Simpler Pricing blog post and also our Pricing page. For any further information regarding our plans, please contact Vercel Support using the support form available from the Vercel dashboard. You can also directly email firstname.lastname@example.org.
