## How Themis Uses This

Themis draws on your product catalog for financial analysis:

* Revenue by product and service line
* Margin analysis (if cost prices are set)
* Cross-sell pattern detection
* Budget vs. actual by product category

## Key Concepts

| Term             | Meaning                                                                             |
| ---------------- | ----------------------------------------------------------------------------------- |
| **Product**      | A physical good in your catalog                                                     |
| **Service**      | A non-physical offering (consulting, subscription, etc.)                            |
| **SKU**          | Stock Keeping Unit — your internal product identifier                               |
| **Price**        | A rate you charge; one product can have multiple prices (e.g. retail vs. wholesale) |
| **Measure Unit** | The unit invoiced in (hours, kg, piece, license, etc.)                              |

## Creating a Product or Service

<Steps>
  <Step title="Go to Products and click New Product">
    Choose type: Product (physical good) or Service.
  </Step>

  <Step title="Enter basic details">
    Name, SKU (auto-generated or custom), description, and category.
  </Step>

  <Step title="Set the default price">
    Enter the unit price and select the measure unit (e.g. per hour, per unit, per license). Set the tax rate that applies.
  </Step>

  <Step title="Add additional prices (optional)">
    Use multiple prices for tiered pricing, different currencies, or customer-specific rates (e.g. retail vs. wholesale).
  </Step>

  <Step title="Set a cost price (optional)">
    Used by Themis for margin analysis. Not shown to customers.
  </Step>
</Steps>

<Tip>
  Set up your full product catalog before creating invoices. Selecting from catalog is faster than entering custom line items, and it keeps your revenue analytics clean.
</Tip>

## Managing Prices

A single product can have multiple price entries:

* **Default price** — Used when no other price matches
* **Tiered prices** — Different rates at different quantities
* **Currency prices** — Prices in foreign currencies for international customers
* **Customer-specific prices** — Override prices linked to a specific counterpart

<Steps>
  <Step title="Open a product and go to the Prices tab">
    Click Add Price.
  </Step>

  <Step title="Set the price, currency, and any conditions">
    Conditions include minimum quantity or a specific counterpart.
  </Step>
</Steps>

## Measure Units

Define custom units that match your business (e.g. "half-day", "10-pack", "API call"):

Go to **Settings → Measure Units** to create and manage units. These appear in the unit dropdown when creating products.

## Best Practices

<AccordionGroup>
  <Accordion icon="tag" title="Use consistent SKUs">
    SKUs let you reconcile orders, invoices, and inventory in external systems. Establish a naming convention before you have hundreds of products.
  </Accordion>

  <Accordion icon="chart-pie" title="Set cost prices for margin visibility">
    Even rough cost estimates unlock Themis's margin analysis. Without cost prices, Themis can only report revenue, not profitability.
  </Accordion>

  <Accordion icon="layer-group" title="Use categories">
    Categorize products from the start. Themis's revenue-by-category reports are only useful if categorization is consistent.
