Pricing Changes

What happens to your customers when you change your prices

When you change a price, new customers pay the new price immediately. Existing customers keep the price they're currently paying and switch to the new price at their next renewal.

This applies whether you raise or lower the price — the rule is the same either way.

Base Price

New customersExisting customers

Example

You change Plan Pro from $99/mo to $129/mo.

A new customer signs up today → pays $129/mo.
An existing customer on day 15 of their month → keeps paying $99/mo.
That same customer at renewal → starts paying $129/mo.

This means you can change prices without worrying about disrupting current customers. They'll always finish their current period at the price they paid.

Usage-Based Pricing (Overage)

When you change the per-unit price for extra usage, the same rule applies: your customer is always billed at the price that was set when their current period started.

Example

You change the overage price from $0.002/call to $0.005/call.
Your customer has already used 5,000 extra calls this month.

This month's invoice → charged at $0.002 (the price when the period started)
Next month's invoice → charged at $0.005 (the new price)

Seat Pricing

Seat prices work the same way as usage pricing. If you change the per-seat price, your customers keep the old price for the rest of their current period.

Example

You change the extra seat price from $25/seat to $35/seat.
Your customer has 3 extra seats.

This month → 3 × $25 = $75
Next month → 3 × $35 = $105
