# Top-ups and auto-recharge
> Buy extra credits, set up automatic top-ups, manage your card, and find your invoices and receipts.
Your plan grants credits every month. When you need more before the next renewal, you buy them —
either manually with a top-up, or automatically with auto-recharge. Both live on the **Credits**
card at **Settings → Billing**, and both are Admin-only.
A top-up adds credits to your balance. It does not change your plan, and it does not reset or
replace your monthly allowance — the credits simply add on, and roll over like any others.
## Buying credits
Go to **Settings → Billing** and find **Top up credits** on the Credits card.
Choose **$10**, **$25**, **$50**, **$100** or **\$250**, or click **Custom** and type your own
figure. Custom amounts are captioned *"USD (1 – 5000)"* and must be whole dollars.
You are taken to a secure checkout page. The charge is taken in your billing currency —
**USD**, **AED** or **SAR** — at the rate set for your plan.
You are returned to **Settings → Billing**. The credits land on your balance as soon as the
payment clears, and a **topup** line appears in **Recent activity**. If you back out of
checkout you see *"Checkout was cancelled — no changes were made."*
You need an active plan to buy credits. If your workspace has no plan yet, subscribe first —
see [Plans](/billing/plans).
## Auto-recharge
Auto-recharge buys credits for you the moment your balance drops below a level you choose. It is
the way to make sure AI replies never stop mid-conversation because the balance ran dry.
On the Credits card, find the **Auto-recharge** row and click **Edit**.
The threshold is in **credits** — when your balance falls below it, a top-up fires. The
default is **100 credits**.
The amount is in **dollars** — how much to buy each time it fires. The default is \*\*$50**,
and the maximum is $5,000.
Save. The Credits card then summarises it as *"On — recharges \$X when balance falls below N
credits"*.
### What you need first
Auto-recharge needs a card already on file. If you have never completed a subscription checkout,
turning it on fails with:
> *"A saved payment method is required to enable auto-recharge. Complete a subscription checkout
> first."*
Subscribe to a plan (or complete any checkout with a card) and then come back.
Auto-recharge charges your saved card automatically, without asking each time, whenever the
balance crosses your threshold. Set the threshold and amount to figures you are happy to be
charged repeatedly in a busy month.
### How it behaves
* It is checked immediately after each charge is settled, so it fires as soon as a debit takes you
below the threshold — not on a schedule.
* It can fire more than once in a month if your usage keeps outpacing the top-ups.
* While auto-recharge is on, Callivox stops sending the low-credit warning email — there is
nothing for you to act on. See [Running low and running out](/billing/running-low-and-running-out).
* If a charge fails — an expired card, for example — you get an email so you can fix it before
work is blocked.
* Turning auto-recharge off keeps your threshold and amount, so switching it back on later takes
one click.
## Payment methods
Cards are handled by the secure payment portal, not by Callivox. Click **Manage subscription** on
the plan card to open it, where you can update your card, change billing details and view your
payment history.
Your billing currency — **USD**, **AED** or **SAR** — is chosen at your first checkout and is
locked while you have an active subscription.
### Workspaces billed by an account manager
Some workspaces, typically Enterprise customers paying by bank transfer, are billed offline. On
those workspaces there is no top-up button and no auto-recharge; the Credits card shows:
> **Billing is managed by your account manager.**
Credits are added for you when your account manager books a credit pack. Contact them to buy more.
## Invoices and receipts
* **Invoices** are listed at the bottom of **Settings → Billing**, with links to the hosted copies.
* **Receipts** for subscription payments are emailed to you automatically.
* **Top-up confirmations** are emailed after each credit purchase.
* **Recent activity** on the same page shows the credit side of every payment: a **topup** line
when you buy credits, a **monthly refill** line when your plan renews.
## Next steps
The warnings you get before, and what stops working after, you hit zero.
Work out how big a top-up you actually need.
