Auto top-up

3 min Mac and Windows Updated 14 October 2026 · App 0.4.4

Auto top-up buys credit with your saved card whenever your balance falls below a minimum you choose, so a call never pauses because your credit ran out. You choose how much it adds each time, the minimum balance, and if you like a most it may spend in a month.

Before you start
  • You are on a plan. Auto top-up is not offered on the free trial.
  • You have a saved card in Billing. Without one, the window says Auto top-up charges your saved card. Add a card in Billing first.

Turn it on

  1. At the bottom of the sidebar, click Settings, then Billing.

  2. Beside Auto top-up, click Turn on.

    Usage credits in Billing with the balance and Buy credit, and under it the Auto top-up row, Automatically buy more credit when you are running low, with its Turn on button; the Auto top-up row is outlined.
    2 Auto top-up sits under your balance.
  3. Under Top up by, click the amount to add each time, or click Other and type one.

  4. Under Minimum balance, type the balance at which to top up. When your credit falls below it, the amount above is added.

    The Auto top-up window: Top up by with $100 chosen, Minimum balance filled in as 10.00, Maximum monthly spend empty showing No limit, and the Turn on auto top-up button; the two fields are outlined.
    4 When to top up. 5 An optional monthly limit.
  5. If you want a limit, type it under Maximum monthly spend. Leave it empty for no limit.

  6. Click Turn on auto top-up. The row in Billing now starts with On: and says how much is added and when.

Change it or turn it off

  1. To change it, beside Auto top-up click Change, edit the amounts, then click Save changes.

  2. To stop it, click Turn off.

What happens next

Each top-up charges your saved card, adds the credit to your balance, and gets a tax invoice and a receipt email like any payment. Check what it has bought under Invoices in Billing.

Common questions

What if my card is declined?

Auto top-up turns itself off, and the row in Billing starts with Off: and the reason. Update your card, then turn it on again.

What happens when I reach my monthly limit?

A top-up that would go over the limit is not made. Auto top-up stays on and starts again next month, counted by the calendar month in Brisbane time.

Is there a smallest amount?

Yes. If the amount is too small, the window says so and asks for more before it saves.
