Billing & Invoicing

Q: Can I use Cloudflare for free?

A: Yes, you can use Cloudflare for free. Cloudflare's Free plan provides the most basic website performance and security features. If you need more, you can always upgrade to a higher tier plan.

Q: What determines the total amount billed?

A: Our pricing is on a 'per-domain' basis. That means that every domain is charged separately - whereas the number of subdomains does not make a difference. For example, if you upgrade and to the Pro plan, they will be charged separately, and you will pay $40/month. You can have as many subdomains like or as you want, and this will not incur any extra charges.

Q: When is my billing date?

A: The date you first select a paid plan will be the recurring billing date. For example: If you sign up for the first time on January 10, all future charges will be billed on the 10th of every month.

Q: What happens when I upgrade?

A: If you currently have a paid plan (e.g. Pro) for one of your domains and upgrade to a higher priced plan (e.g. Business), the following happens:

  • You will be debited the hourly pro-rata cost of the Business plan until the end of the billing cycle
  • You will be credited the hourly pro-rata cost of the Pro plan until the end of the billing cycle
  • At the beginning of the next billing cycle, you will be charged for the full cost of the Business plan
  • You will receive an invoice upon successful payment of the upgrade

Q: What happens when I downgrade?

A: If you select a domain and downgrade from a higher-priced plan (e.g. Business) to a lower-priced plan (e.g. Pro), the following happens:

  • Your domain will immediately be downgraded and no longer benefit from the higher-level Cloudflare plan you have pre-paid for
  • Your billing will be adjusted at the start of the next billing cycle to reflect the Pro plan's charges
  • You will not receive a refund for the funds you have pre-paid for the higher priced plan

Q: How are prorations calculated?

A: If you are moving from a lower-priced plan to a higher-priced plan, you are charged as follows:

  • Pro-rata remaining days = # of days remaining in the current billing cycle / # of total days in the billing cycle
  • Credit for unused lower priced plan = price of lower plan * pro-rata remaining days
  • Debit for remaining higher-priced plan = price of higher plan * pro-rata remaining days
  • Amount Due for Zone = Debit for higher-priced plan - Credit of lower-priced plan

Q: What happens if I add a plan in the middle of my subscription period?

A: Your additional zone will be charged for the pro-rata time used for the selected plan. For example:

  • Your first zone is subscribed to a paid plan on the 10th of the month and you add a second zone on the 20th day of a 30 day month
  • You will be charged an additional (20/30) * price of the second plan
  • On the next billing cycle (10th of the next month) you will be charged the full price for both plans
