# Add a product or service

> Create catalogue items with price, unit, VAT category and HS code so invoice lines fill in with one click.

Items are the products and services you sell. Picking one on an invoice line fills the description, unit, price and VAT, which keeps invoices consistent and fast to write.

## Steps

1. Go to **Items** and click **Add Item**. The dialog has two tabs.
2. **General**:
- **Type**: **Product** or **Service**.
- **Name** (required) and **Name (Arabic)**.
- **Description**: shown under the line on the invoice.
- **HS code** (the customs tariff code of the goods, BT-158), **Item number** (the wand takes the next number of the item series, `IT-{n}` by default, set under **Settings → Outgoing invoices → Document Numbering**) and **Category**.
- **SKU**, **Barcode** and **GLN / GTIN**. The SKU is sent as the seller's item identifier and the barcode (else GLN / GTIN) as the item's GTIN on e-invoices.
- **Reverse-charge goods type** (only when the VAT category is Reverse charge): gold and diamonds, electronic devices, or oil, gas and hydrocarbons. Reverse-charge e-invoices need it and the item's GTIN.
3. **Tax & Pricing**:
- **Currency** (AED by default) and **Unit Price** (required).
- **Unit of Measure**: Each, Hour, Day, Month, Kilogram, Metre, Litre, Square metre, Set or Piece.
- **Tax Category**: Standard (5 %), Zero Rated (0 %), Exempt or Reverse Charge, and **Tax Rate (%)**.
- **Cost price** (the margin is shown next to it) and **Track inventory** with **Stock on hand** and **Low stock warning at**.
4. Click **Save**.

## Good to know

- With **Type** set to **Service**, the HS code, SKU, Barcode, GLN / GTIN, Cost price and Track inventory fields are hidden and not saved; they only apply to goods. A **Service accounting code** field appears in place of the HS code.
- On e-invoices a line picked from a product with an HS code is sent as Goods with that code, and a line picked from a service with a service accounting code is sent as Services with that code. An item without a code states no type.
- On an invoice line, click the product icon, search and pick the item. You can still change price, quantity and VAT on that line only.
- **Add product…** inside the line picker opens the same dialog, so you can create items while writing an invoice.
- The list can be searched by name, HS code or SKU and filtered by type and tax category.
- Import many items at once with **Import Data** (CSV, JSON, XML or XLSX; columns name, type, description, SKU, unit price, unit code, currency, tax category, tax rate, HSN/SAC code (the HS code), barcode).
- Whether the HS code and unit columns are printed on the PDF is a setting of the document design.
- With **Track inventory** on, stock decreases when an invoice with the item is issued.
