## Overview

Learn how to automatically generate professional PDF invoices with these essential features:

-   Automatic table header repetition on page breaks
-   Dynamic calculation of product totals
-   Automatic page numbering
-   Customizable color themes

## Step-by-Step Guide

Follow these steps to create your invoice template with Carbone:

### 1\. Basic Layout Setup

Start by inserting Carbone tags for your company information. Format the text and spacing to create a professional layout.

Example:

```text
{d.company.name}
{d.company.address}
{d.company.postalCode} {d.company.city}
```

For your company logo, insert a placeholder image and set its URL using the **View Alt Text** option.

### 2\. Product Table Creation

Create a table to display your product information:

-   Insert a table with columns for products and their details (prices, quantities, etc.)
-   Add dynamic calculations using formatters (e.g., `:mul()` to calculate subtotals)
-   Set up product iteration using:
    
    ```text
    {d.products[i+1]}
    ```
    

**Important:** In table properties:

-   Set text wrapping to **None**
-   Uncheck **Allow row to break across pages** for better layout consistency

### 3\. Header Row Configuration

To ensure your table header appears on every page:

-   Select the first row of your table
-   Right-click and open **Table Properties**
-   Go to the **Row** tab
-   Check **Repeat as header row at the top of each page**

### 4\. Total Calculation Setup

Add a summary table for invoice totals:

-   Use [:aggSum](/documentation/design/computation/aggregation.md#learn-with-aggsum-partitionby) to calculate total amounts
-   Apply [:formatC](/documentation/design/formatters/currency.md) for proper currency formatting

Example:

```text
{d.products[].priceTotal:aggSum:formatC}
```

### 5\. Page Numbering

Add automatic page numbers:

-   Click **Insert** in the menu
-   Select **Page Number**
-   Choose your preferred footer position

### 6\. Dynamic Color Theme

Customize your invoice colors dynamically with the [:color](/documentation/design/advanced-features/colors.md#color-scope-type) formatter:

For text color:

```text
{d.color:color(p)}
```

For row background color:

```text
{d.color:color(row, background)}
```
