title: Platform capacity
description: The headroom your whole program draws from, and how to see where it went.

Your customers do not each hold their own capacity — they draw from your
program's. **Platform capacity** is that shared pool: the call minutes and the
simultaneous calls available across every customer you have.

This is the number to watch as you grow. A program can be commercially healthy
and still have customers hitting a ceiling, because the ceiling is yours rather
than theirs.

## Reading the pool

The capacity screen shows what the program holds and how much of it is
currently spoken for. When the pool runs low, the portal reminds you — that
reminder is worth acting on before a customer notices, not after.

## The capacity ledger

Every movement in and out of the pool is recorded in the **capacity ledger**: a
running history of what was added and what was consumed, and when.

Use it when the pool looks lower than you expected. The ledger shows the
movement that explains it, which the summary figure on its own cannot.

## When capacity runs out

Capacity is a ceiling, not a bill: calls do not silently cost more once the pool
is thin, they stop being possible. Customers experience that as calls not being
answered, so treat a low pool as an outage waiting to happen rather than a
number to tidy up later.

Adding capacity is a change to your own plan with the platform — see
[Pricing & billing](./billing.md).
