Choose a plan and buy volume

You buy two things separately.

What you buy	What it gives you	How it is paid
A plan	Features, seats and how long messages are kept	Charged monthly, with or without a commitment
Volume	Operations on top of the ones your plan includes	Prepaid packs, valid twelve months, cumulative

The consequence is the point of this model: increasing your capacity never changes your subscription. You do not move up a tier to receive more messages.

Prices and a simulator are on the Pricing page. They are not copied here, so that a stale price list cannot sit around in an article.

The twelve-month commitment

You pay 20 % less, and you are charged every month exactly as without a commitment: you never pay twelve months up front.

In exchange you cannot move down a plan before the twelve months are up. Moving up stays possible at any time, and the discount follows the new plan.

When your period renews

Your capacity resets on the anniversary of the day you subscribed, not on the first of the month. An account opened on the 17th sees its included volume start again on the 17th.

That date is shown on Settings → Billing, next to what you have left. If you subscribed on a 29th, 30th or 31st, your date is the 28th.

What that changes for you

A test suite does not have a steady throughput: it sleeps for a week and saturates on a Tuesday evening release. Three practical consequences:

• You size for what you use, not for your peak. A pack is bought the day it is useful.
• A purchase does not commit you for the month. Your packs are not reset at the next cycle: they run for twelve months.
• Moving down a plan destroys nothing. Packs you have already bought stay usable, whatever plan you land on.
• Stopping your subscription destroys nothing either. Your packs are set aside until their twelve months are up: they cannot be used without an active subscription, and they become usable again if you subscribe again within that time.

Pay-as-you-go, as a safety net

It exists and it is priced above the cheapest pack. Set a spend cap: past it, it stops.

It is there so that a runaway suite on a Friday evening does not block your tests on Monday, not to be your normal mode. If you use it every month, a pack will cost you less.

Track the capacity you have left

Settings → Billing shows what you have left and where it came from: included with the plan, a pack you bought, pay-as-you-go, or an adjustment from us. Every line carries its expiry date.

That count is the authority, not whatever a payment provider says. It is what lets a pack survive a plan change, and a spend cap be honoured to the second.

Known limits

• Online payment is not active. Write to us to choose a plan, buy a pack or change your subscription: we do it for you, and Settings → Billing shows where your account stands in the meantime.
• You see the open period, not the previous ones. The count for the open period is accurate to the second; the history of closed periods is not shown yet. See Quotas and retention.
