Why Legion Global Sales Tax?

Standard Odoo applies taxes per product line, requiring businesses to manually configure tax rules for every single product. The Legion Global Sales Tax module allows companies to apply a single percentage tax across the entire order or invoice at once, combined with freight charges, making it ideal for businesses that charge a flat rate tax, import duties, customs fees, or surcharges that apply to the total transaction value rather than individual items.

Global Sales Tax

The Legion Global Sales Tax module adds a global tax percentage field and freight charges field directly on sales orders and invoices, allowing businesses to apply document-level charges without creating additional product lines.

Key Features:

  • Global Tax Percentage: Adds a single global tax percentage field on both sales orders and invoices, automatically calculating and applying the tax across the entire order total without needing to configure per-product tax rules.
  • Freight Charges Integration: Includes a dedicated freight charges field alongside global tax, allowing businesses to add shipping and delivery costs directly on sales orders and invoices with automatic total recalculation.
  • Smart Total Calculation: Automatically computes the final total as Subtotal + Line Taxes + Global Tax Amount + Freight Charges, ensuring accurate financial figures throughout the entire sales and invoicing workflow.
  • Correct Accounting Entries: Generates proper signed journal entries during invoice confirmation, handling both customer invoices (positive) and credit notes (negative) with accurate amount_total_signed values for correct financial reporting.
  • Full Change Tracking: Both global tax percentage and freight charges fields include complete audit trail tracking, recording every modification with timestamps and user information for compliance and dispute resolution.
  • Seamless Workflow Integration: Works within standard Odoo Sales and Accounting workflows without disrupting existing tax configurations, product pricing, or reporting structures, requiring zero additional setup after installation.

Frequently Asked Questions

Does Global Tax stack on top of existing product line taxes?

Yes! The global tax is calculated on amount_untaxed (subtotal only) and added on top of existing line taxes. The formula is: Final Total = Subtotal + Line Taxes + (Subtotal × Global Tax%) + Freight. This means if your products already have 10% VAT configured and you add 5% global tax, both are applied separately without conflict.

Can I use Global Tax and Freight Charges independently?

Yes! Both fields are completely independent. You can use only Global Tax with no freight, only Freight with no global tax, or both together. The system intelligently handles all combinations - if both are zero, standard Odoo calculation applies without any interference from this module.

Does the Global Tax percentage transfer from Sales Order to Invoice?

Yes! When you create an invoice directly from a confirmed sales order, both the global tax percentage and freight charges are automatically carried over to the customer invoice, maintaining consistent totals between the sale order and invoice without any manual re-entry.

How does this differ from Odoo's standard tax groups?

Odoo's standard taxes are configured per product/account and apply during line item entry. The Global Tax is a single percentage applied at document level after all line items are entered - ideal for customs duties, import surcharges, or government levies that apply to total transaction value regardless of individual products.

Will this affect my existing financial reports?

The module correctly updates amount_total, amount_total_signed, and amount_total_in_currency_signed fields, which are the fields used by Odoo's standard financial reports. Your Profit & Loss, Balance Sheet, and Tax reports will all reflect the correct totals including global tax and freight charges.

Can I set a default Global Tax percentage for all orders?

Currently the global tax defaults to 0% and must be entered manually per order or invoice. If you need a company-wide default percentage, a small customization can be added to read the default from company settings. Contact our support team within the 90-day support period to request this enhancement at no additional cost.
