1. Installation of LibreOffice

The first step is to install LibreOffice on your computer if it is not already done. Visit the official LibreOffice website, download the latest version, and follow the installation instructions for your operating system.

2. Configuring Business Information

Before creating an invoice, gather essential information about your business. This includes the business name, address, contact details, and VAT number. This information should be clearly displayed on all your invoices.

3. Choosing or Creating an Invoice Template

LibreOffice Writer allows you to use existing templates or create your own. To access the templates:

• Open LibreOffice Writer.
• Go to "File" -> "New" -> "Templates".
• Search for an invoice template among those available.

If no predefined template meets your needs, you can create a custom template:

• Create a new blank document.
• Add headers, tables, and text fields necessary for an invoice.
• Include your business logo for a professional touch.
• Save your document as a template via "File" -> "Templates" -> "Save as Template".

4. Entering Invoice Details

Fill your template with specific details:

• Invoice date.
• Unique invoice number.
• Customer information (name, address, contact).
• Description of products or services provided.
• Quantity, unit price, and total amount.
• Payment terms and deadlines.

5. Automatic Calculation with Formulas

LibreOffice Writer allows the use of simple formulas for automatic calculations in tables. To add automatic calculations:

• Select the cell where the calculation should appear.
• Use the SUM function to add the amounts.
• Ensure that formulas are correctly updated with each new invoice.

6. Saving and Exporting the Invoice

Once your invoice is completed, you will need to save it and send it to your customer. LibreOffice Writer allows you to export your invoices in PDF format, a widely used format for compatibility and security reasons.

• Go to "File" -> "Export As" -> "Export as PDF".
• Check the export settings, then click "Export".

7. Archiving and Managing Invoices

Finally, set up a filing system to keep your invoices. This could be a digital folder on your computer or a secure online storage service. Archiving ensures legal compliance and facilitates the management of financial documents.

Tutorial: Step-by-Step Procedure in LibreOffice Writer

The Steps

1. File -> Page Properties: A4, Portrait, margins 20 mm.

2. Insert -> Header & Footer -> Header: create a 2-column table (without border).

   • Left column: Insert -> Image -> your logo.
   • Right column: enter company info (use style "HeaderCompany").

3. Under the header create a paragraph with two boxes side by side:

   • Insert -> Table (2 columns) or use two sections/tables without borders.
   • Fill in "Billed To"/"Invoice Info".

4. Insert > Table: create the line table (6 columns). Set column widths according to the structure above.

   • To add or remove rows: right-click -> Insert / Delete.

5. Calculations:

   • Option A (recommended, simpler & more reliable): Insert -> Object -> OLE Object -> LibreOffice Spreadsheet. Design your table in the built-in mini-Calc; the formulas are standard (e.g., for row 2: =C2*D2, subtotal =SUM(E2:E10), VAT =Subtotal*0.20, Total =Subtotal+VAT). The result appears automatically in Writer.
   • Option B (Writer only): you can use Table -> Formula but syntax varies and can be less convenient; prefer the OLE object if you want robust formulas.

6. Totals Block: Create a small 2x4 table to the right of the main table (without borders), place the Subtotal / VAT / Total fields. Bold the Total and set a light background via Format -> Table -> Background.

7. Footer: Insert bank details and legal mentions.

8. Styles: Create paragraph styles (InvoiceTitle, HeaderCompany, ClientInfo, TableHeader, TableCell) for global modification.
