# balance.low

> Prepaid balance dropped below 10% of the last refill.

## When this fires

The async usage processor watches every balance deduction. When a batch moves the prepaid balance from above to at-or-below 10% of the last refill (period reset, top-up, or manual adjustment), this event fires once per crossing. A top-up re-arms it.

Amounts are in rate scale (10000 = \$1.00) in the subscription currency.

Use it to prompt the customer to top up before usage gets blocked.
