# Catalog settings

> Set up product categories, variant keys, brands, units of measure, and expense categories that your products and expenses draw from.

**Settings → Catalog** is where you set up the building blocks that your
products, services, and expenses draw from — categories, variants, brands,
and units. Getting these right first makes adding products and expenses
faster later.

### Categories & Variant Keys

Create the product categories you'll use to organize your catalog (like
"Groceries" or "Electronics"). Categories can also have their own
category-specific **variant keys** — for example, a "Clothing" category
might have a "Size" and "Color" variant key, while an "Electronics"
category might have a "Storage" variant key. These variant keys are what
show up when you add a product that comes in multiple variants, so set
them up on the category before you start adding products that need them.

### Brands

Add and manage the manufacturer or product brands you sell. Once a brand
exists here, it becomes available to pick from when creating or editing a
product — useful for filtering and reporting by brand later.

### Units of Measure

Manage the units (like kg, litre, or piece) used when creating products and
services. See [Units of measure](/customer-guide/products-and-services/units-of-measure)
for the full guide.

### Expense Categories

Set up the categories used to classify your business expenses. See
[Tracking expenses](/customer-guide/purchases-and-expenses/tracking-expenses)
for how these are used day to day.

## Try it: Bali Electronics

<Steps>
  <Step title="Vikram creates an Electronics category">
    Vikram Bali opens **Settings → Catalog → Categories & Variant Keys** and
    creates a "Mobile Phones" category for his stock.
  </Step>

  <Step title="Adds a Storage variant key">
    Since phones come in different storage sizes, he adds a "Storage"
    variant key to the Mobile Phones category, so it'll be available when
    Deepak adds phone products later.
  </Step>

  <Step title="Adds a brand">
    Vikram then opens **Settings → Catalog → Brands** and adds "Samsung" and
    "Apple" so they can be picked when creating new phone products.
