# Your plan, invoices and payment method

The Adaptive plan at $399 a month, where to find invoices and billing history, and how to change your card.

K3X has one plan, **Adaptive**: $399 per month, 400,000 credits a month, unlimited seats. Everything about it lives in **Settings → Billing**, with payments processed by Stripe.

## The plan

-   **Price**: $399 per month for the whole team.
    
-   **Credits**: 400,000 every billing cycle, in one pool for AI, calling, texting and data reveals.
    
-   **Seats**: unlimited. A seat is one named user; add or remove teammates at no extra cost.
    
-   **Top-ups**: $99 per 100,000 credits, never expire while the plan is active.
    
-   **Trial**: 7 days free before the plan starts.
    

The **Your plan** card in Billing shows your credits a month, the price, a **Manage plan** button and your **Renews** date.

## Monthly or annual

The plan in the app renews monthly. The Terms of Service also allow annual billing; ask hey@k3x.ai if you want to pay yearly. Subscriptions renew automatically until you cancel.

## Invoices and billing history

1.  Open **Settings** (gear icon) → **Billing**.
    
2.  Scroll to **Billing history**. Every charge is listed: the monthly plan, top-up packs, auto-recharges and any pass-through carrier fees.
    
3.  Open an entry to download the invoice or receipt.
    

Need a different billing address or company name on invoices? Click **Manage plan** to open the Stripe billing portal and edit your details.

## Change your card

1.  Open **Settings → Billing**.
    
2.  Under **Payment & invoices**, find the card on file and click **Change**.
    
3.  Enter the new card. Stripe stores it; K3X never sees or stores full card numbers.
    

## Failed payment

If a charge fails (declined, expired or cancelled card), paid actions pause until the card is fixed. Your data is untouched. Update the card as above and the plan resumes. If you see a payment banner in the app, that is the fastest path.

## Price changes

If the price of a monthly plan changes, K3X gives at least 30 days' notice. Annual plans change at renewal.

## Taxes

Prices do not include sales tax or VAT where it applies. Tax, if any, appears on your invoice.

## Who can manage billing

Owners and administrators. Other roles can see usage but cannot change the plan or card. See "Roles and permissions: Owner, Administrator, Sales Manager, Sales Representative".
