Hope it helps

If you're using Odoo Online, customization options are limited unless:

1. You have Studio activated (Enterprise users).
2. You're exporting to Excel/PDF and adding details manually.
3. You contact Odoo Support for help with a custom PDF template (available on higher-tier plans).

For Odoo Studio (Enterprise Online) users:

1. Go to:

Settings → Activate Studio → Navigate to Reports → Statement Template

2. Add Fields:

• Click "Add" and insert fields like due date, reference, or payment terms.
• You can also include related records like:
  • Invoice lines → Product
  • Invoice lines → Taxes
  • Journal Items → Account

3. Save and Test:

• Print a sample statement from Customer → Action → Print Statement.
