# FAQs

<AccordionGroup>
  <Accordion title="How do I handle charges for shipping?">
    Shipping and handling charges should be treated as their own distinct products and line items. Before you begin selling, we recommend you create at least one designated shipping product. Some customers will choose to track multiple shipping SKUs (expedited vs standard, for example), but when creating the shipping SKU, make sure to categorize it as `SHIPPING`.
    When it's time to calculate taxes, you can pass in the shipping costs just as another line item to the `tax/calculations` endpoint. Use these links to find more info about our [product categories](/essentials/product-categories), [creating products](/endpoint/products), and [calculating taxes](/endpoint/calculations).

  <Accordion title="How do I change a product's category?">
    To change a product's category, you'll have to first
    [delete](/endpoint/delete_product) the original product and then
    [re-create](/endpoint/products) the product using the new category. You can
    re-use the same product ID.

  <Accordion title="What will happen if I’m not registered to collect tax in some states?">
    Numeral will keep track of all your registrations and nexus - you can view the current status on the Nexus page of your [Numeral dashboard](https://dashboard.numeralhq.com/nexus).
    If you haven't yet crossed nexus in a state or are still in the registration process, Numeral won't suggest tax rates to collect when you hit the `tax/calculations` endpoint. Instead, the tax\_jurisdictions component of your response will look like this:

    ```
    "tax_jurisdictions": [
            {
              "tax_rate": 0.00,
              "rate_type": "NO COLLECTION; NO STATE NEXUS",
              "jurisdiction_name": "State"
            }
          ],
    ```

    As soon as the registration is complete, we'll automatically adjust your jurisdiction setting to note that you are collecting tax. From there, we'll return the tax information in full.
    Note, that even if you aren't collecting tax in a state, it's especially important to send all transactions over via the `tax/transactions` endpoint so we can keep track of when you *do* cross nexus and can kick off your registration.

  <Accordion title="What do I need to do when I cross nexus in a new state?">
    Numeral will automatically monitor your nexus and alert you when you cross the threshold. As soon as you cross the threshold in a particular state, we'll kick off a registration for you to make sure that you remain compliant.
