# Smarty Discounts settings and billing

> Language, display currencies, weight, test domain, theme app embed, and upgrading your plan.

<Info>
  These options apply to your **whole shop** in Smarty. They affect how rules are shown and interpreted, not the logic inside a single discount (that’s [Features](features)).
</Info>

**Creating discounts:** [Create a discount](create-discount)

## Open Settings

<Steps>
  <Step title="Apps">
    **Apps** → **Smarty Discounts**.
  </Step>

  <Step title="Settings">
    Click **Settings** in the app menu.
  </Step>
</Steps>

## Language

Choose the language for **Smarty’s admin screens** (or follow Shopify / user preference if that option exists). **Save** if the page has a save bar.

So your team sees condition labels in the language they prefer.

## Display currencies

Use when customers can pay in **more than one currency** (Shopify **Markets** or multiple presentment currencies).

<Steps>
  <Step title="Open list">
    In **Settings**, open **Display currencies** (or the currencies list for the editor).
  </Step>

  <Step title="Add currencies">
    **Add every currency** you sell in — match what Shopify offers at checkout.
  </Step>

  <Step title="Save">
    **Save**.
  </Step>
</Steps>

### Why it matters

* **Percentage** discounts use **one** percentage for all currencies.
* **Fixed money** ($off, fixed price, money tier steps, max$ caps) needs a value **per currency**. Smarty shows **one column per currency** you enable here.
* If a currency is **missing**, you may not be able to enter amounts for that checkout currency.

**More detail:** [Multiple currencies](features#multiple-currencies).

## Weight unit

Pick **grams, kilograms, ounces, or pounds** so cart and product weight rules match how you think (e.g. “cart weight > 10” means 10 lb vs 10 kg consistently). **Save**.

## Test mode email domain

Set a domain for **staff test accounts** (e.g. `@yourbrand.test`). Emails using this domain can be treated as **test** users when you use **test mode** on discounts, so you do not rehearse on real customers. **Save**.

## Theme app embed

<Steps>
  <Step title="Open from Settings">
    In **Settings**, find **Theme** or **App embed** and open the **theme editor** link.
  </Step>

  <Step title="Enable">
    **Enable** the Smarty embed. **Save** on the theme.
  </Step>

  <Step title="Live theme">
    Repeat for your **live** theme.
  </Step>
</Steps>

**Checkout** still applies discount math in Shopify; the embed is for **online store** behavior (messages, widgets, etc.). More: [Storefront and checkout](storefront-theme).

## Billing

<Steps>
  <Step title="Billing menu">
    Click **Billing** in the app menu.
  </Step>

  <Step title="Compare plans">
    See **[Plans](plans)** for tiers, prices, and which discount types and rule presets each tier unlocks.
  </Step>

  <Step title="Upgrade when needed">
    Upgrade inside **Billing** when you need capability your current tier does not include (see **[Plans](plans)** for the full matrix).
  </Step>
</Steps>
