# AI Balance & Packs

> How AI features and calls are paid from a prepaid balance, what AI Chat and AI Calls packs are, and how auto top-up works.

AI features and calls aren't included in the plan price. They're paid from a prepaid balance that the whole workspace shares. You add money to it by buying AI packs or topping up, and each use takes a little from it.

Your plan decides who can **use** AI. The balance decides whether there's money to **pay** for it. The AI assistant comes with [Pro](https://workstation.repzo.com/docs/commerce/plans-and-add-ons#crm-plans), and AI agents come with [Inbox & Calls](https://workstation.repzo.com/docs/commerce/plans-and-add-ons#add-ons).

Find the balance in **Billing → Usage balance**. It's shown as the **Repzo Usage Balance**.

## Three kinds of credit

The balance is one amount of money, split by what it can pay for:

| Credit | Pays for | Comes from |
|---|---|---|
| **AI Chat** | AI replies, the AI assistant, and AI agents | AI Chat packs |
| **AI Calls** | Call minutes, phone numbers, and recordings | AI Calls packs |
| **General credit** | Both | Top-ups, and any balance you had before packs existed |

When something uses AI, Workstation spends from the matching credit first, then from general credit. Within each, the oldest credit is used first. The **By balance** section shows how much is left in each.

Voice calls are charged per started minute, at the published rate for the destination.

## Buy an AI pack

Packs are the simplest way to add credit for one purpose.

1. Go to **Billing → Usage balance**.
2. Under **AI packs**, choose an AI Chat or AI Calls pack. Each pack shows its price, an estimate such as the number of messages or minutes it covers, and when its credit expires.
3. Select **Buy for** and complete the payment.

The credit is added once the payment is confirmed. Estimates are based on typical usage, so your actual number of messages or minutes may differ.

## Top up general credit

Use a top-up when you want credit that can pay for both AI and calls.

1. Go to **Billing → Usage balance**.
2. Under **Top up general credit**, pick an amount or enter a **Custom amount**. The minimum is $5.
3. Complete the payment.

## Auto top-up

Auto top-up adds credit automatically when the balance runs low, so AI replies and outbound calls don't stop.

1. Go to **Billing → Usage balance**.
2. Under **Auto top-up**, select **Manage**.
3. Turn on **Enable auto top-up**.
4. Set **When balance is below** (the threshold) and **Purchase this amount** (between $5 and $1,000).
5. Select **Save**.

Auto top-up charges the default card saved on your billing account. Manage cards in **Billing → Settings → Payment method**. If a charge fails, the section shows **Failing**. Check your payment method.

## When the balance is empty

With no credit left, paid AI features and outbound calls pause until you add more. The rest of Workstation keeps working.

An inbound call that's already in progress isn't cut off when the balance runs out. The cost is shown as **Inbound call balance due**, and your next paid top-up repays it first. AI Chat pack credit is never used to repay call costs.

## Recent grants

**Recent grants** lists every credit added to the balance, newest first: how much, where it came from (for example, paid or promotional), when it was added, and how much is left.
