# Quotes and payment

> How an AI assistant quotes domains and email at Sidemex and hands you a payment link that you confirm.

At Sidemex, **an AI assistant never completes a payment on its own**. It prepares the purchase and you confirm it.

## Flow

```text
search  →  quote  →  payment link  →  you pay on sidemex.net  →  delivery
```

1. **Quote.** The assistant requests a quote with domains, years and mailboxes. Sidemex computes the price server-side and returns a signed, expiring quote.
2. **Payment link.** The assistant creates a `sidemex.net/checkout` link with the quote preloaded.
3. **You pay.** By card, balance or other methods available at checkout.
4. **Delivery.** Sidemex registers the domain and creates the mailboxes. The assistant can check the order status.

## Guarantees

- Sidemex always computes the price; the assistant cannot change it.
- Quotes expire; if the price changes, a new one is issued.
- Additional paid mailboxes also go through the payment link.
