# Products and services

> Register the catalog of products and services, control balance and minimum stock, adjust quantities, set NCM and tax treatment and print labels.

The **Catalog of Products & Services** is the basis of orders, sales and tax invoices: what you sell, the price, the cost and how much you have in stock.

## When to use

Before creating orders or sales with catalog items, and whenever you need to correct price, balance or tax data.

## Before you start

Inventory module in the plan and permission in your role. The menu is at **Management > Inventory > Products & Services**.

## Register an item

**1. Click New Product / Service**

Available at the top of the list.

**2. Identification tab**

Fill in **Name**, **Internal Code (SKU)** and **Barcode (EAN)** (unique per company) and **Category**. You can create a **New category** on the spot.

**3. Type & Unit tab**

Check **It is a Service (no stock control)** when applicable. Choose the **Unit of Measure** (Unit, Hour, Day, Month, Km, Kg, m², Liter or Service). Enter **NCM** (required for product NF-e) and, for services, the **Service Code (LC 116)**. Choose the **Default Supplier**, if any.

**4. Prices tab**

**Sale Price (R\$)** and **Cost Price (R\$)**. The cost is updated automatically in goods receipts.

**5. Stock tab**

**Current Stock** changes automatically with receipts, adjustments and orders. **Minimum Stock** sets the alert point.

**6. Description tab**

**Detailed Description** and **Active in catalog**. Inactive items do not appear when creating sales.

## Part tax treatment

In **Type & Unit**, the **Part tax treatment** field is optional: fill it in only if the item is taxed differently from the others. If in doubt, ask your accountant.

| Option | When |
| :- | :- |
| ICMS already charged earlier (tax substitution) | Part with ST. |
| Single-phase PIS/COFINS (already collected by the manufacturer) | Single-phase item. |
| Tax substitution + single-phase PIS/COFINS | Common in auto parts. |
| Exempt / non-taxed | No taxation. |
| Custom (enter the accountant's codes) | Unlocks ICMS CST/CSOSN, rate, CFOP, PIS and COFINS. |

The item's treatment takes priority over the [tax profile](https://docs.notfy.ai/en/fiscal/perfis-fiscais.md) at issuance.

## The list

Columns: **Active**, **Type**, **SKU**, **Name**, **Category**, **Sale**, **Cost**, **Stock** and **Supplier**. Filters: **Category**, **Type**, **Active** (on by default) and **Low stock**.

## Adjust the stock

To correct the balance (physical count, loss, bonus):

**1. Open the product**

Click edit and use **Adjust Stock** at the top.

**2. Enter the quantity**

In **Quantity (positive = receipt, negative = issue)**, type the value. The current stock appears as a reference.

**3. Write the reason**

**Adjustment Reason**, for example "Physical count". Confirm: "Stock adjusted!".

On the product's edit page there are also the **Movements** tabs (history of receipts, issues and adjustments with the balance after each one), **Purchase History** and **Cost analysis** (evolution of the purchase cost).

## Labels

In **Actions > Label** in the list, see the preview and choose **Print on Thermal Printer** (printer configured in [Stock settings](https://docs.notfy.ai/en/operacao/configuracao-de-estoque.md)) or **Download PDF**.

## Frequently asked questions

> [accordion] Can the balance go negative?
>
> No. When an issue is larger than the balance, the balance stops at zero, although the movement records the requested quantity.

> [accordion] Does a service control stock?
>
> No. Items marked as a service do not move the balance.

> [accordion] Why does the item not appear in the sale?
>
> Check that **Active in catalog** is on.
