Questions and answers

Buying

Which payment methods do you accept?

We accept credit card, Apple Pay, Google Pay, SEPA Direct Debit (EUR plans only) and BECS Direct Debit (AUD plans only) payments. Learn more about supported payment methods.

Invoice payment is available on the Company plan. For more flexible payment options, contact us.

Do you offer not-for-profit, educational or open source discounts?

Not right now. All plans are full price, though we hope to offer discounts for some organisations in the future.

Using

How many tests do I need?

One test equals a single URL and Test Profile combination. The number of tests rises with the number of Pages (unique URLs) and Test Profiles and is multiplied by your test schedule.

You can monitor your usage on the Billing page. Calibre will also show predicted usage as you create a new Site. You can always upgrade or downgrade your plan and add or remove Test Pack(s) to control the test capacity.

What happens when I use my test allocation?

We alert account admins when you reach 80% and 100% of the monthly test allowance. When the allocation runs out, Calibre stops testing until the start of the next billing cycle.

To increase your monthly test capacity, upgrade your plan or add Test Pack(s).

What happens when I use all my Real User Monitoring sessions?

On Starter, Real User Monitoring pauses at 5,000 sessions until the next billing cycle. Team includes 10,000 sessions, then adds packs of 100,000. Company includes 1 million, with volume discounts after that.

Lower your sampling rate to use fewer sessions.

How can I add more people to my organisation?

Each plan includes a number of seats. Once you reach it, add more people at $15 per seat per month, or upgrade to a plan with more included.

What’s the difference between Admin, User and Viewer?

Admins are people who have complete control over your organisation.
Users are contributors who control what gets monitored and how.
Viewers have read-only access, so they are people who need to be able to view but not change performance monitoring data available in your account.

See a full breakdown of role permissions.

Company plan organisations also get a security audit log of every sign-in, member change and API key event.

How long do you keep my metrics for?

Synthetic test data is kept for the life of your account, on every plan. Real User Monitoring data is kept for 90 days on Starter, 1 year on Team and 2 years on Company.

If you decide to cancel your subscription, we immediately and permanently delete all of your data. We don’t keep data we don’t need.

Billing and management

Where can I get an invoice?

You can view your invoices with relevant tax information on Billing → Invoice History and Settings page:

  1. Log in to Calibre.
  2. Click Manage organisation in the upper right-hand corner.
  3. Select the Billing tab.
  4. You can find your invoices under Invoice History and Settings.

Only Admins can view and manage the billing and payment settings. Admins and nominated billing email also receive the PDF invoices after each payment is collected.
