Annual vs. monthly billing

When you choose a paid plan, you can pay monthly or annually.

• Monthly — flexible, pay as you go. You can up-/downgrade any time.
• Annually — a 20% discount on Basis, Pro and Enterprise in return for paying a year at a time. Shown at checkout.

A few details:

• Whether you pay monthly or annually, your call quota resets every month.
• If you upgrade mid-period on monthly billing, a new period starts the same day with the new plan's full quota; we deduct the share of your current plan you have used neither in time nor in calls — if you have used up the quota, you pay the new plan's full price. On annual billing you pay the difference for the rest of the year. Downgrades and billing-interval changes take effect at the next renewal.
