Global Tax on Sale Order & Purchase Order

Apply global taxes on all sale order and purchase order lines at once — no more editing each line individually!

Odoo v19 Community & Enterprise Odoo.sh On-Premise

Key Features

🌍 Global Tax Field

A new Global Taxes field appears on both Sale Order and Purchase Order forms, right above the order lines.

⚡ One-Click Apply

Select one or more taxes and they are instantly applied to every order line — saving time on orders with many products.

🔄 Replace Default Taxes

Global taxes replace the default product taxes on each line, ensuring consistent tax treatment across the entire order.

📦 Works with Sales & Purchases

Supports both Sale Orders and Purchase Orders — one module, two workflows covered.

🏷️ Multiple Tax Support

Select multiple taxes at once (e.g., GST + Cess) and all are applied to every line simultaneously.

🛡️ Invoice-Safe

Lines that are already invoiced or billed are never changed — your confirmed financials stay protected.

How It Works

  1. Add products to your Sale Order or Purchase Order as you normally would. Each line gets its default product taxes.
  2. Select Global Taxes in the new field above the order lines. Choose one or multiple taxes from the dropdown.
  3. All eligible lines update instantly. The selected global taxes replace the default taxes on every non-invoiced line.
  4. Totals recalculate automatically. Subtotal, Tax, and Total amounts reflect the new global taxes.
🔒 Invoice Protection: Lines with qty_invoiced > 0 (already invoiced/billed) are never modified. Once an invoice or bill has been created, the tax on that line is locked — ensuring your accounting stays accurate.

Before & After Comparison

Sale Order: Default Taxes Calculation

❌ Without Global Tax

Each line has its own default tax — you must edit them one by one.

ProductQtyPriceTaxesSubtotal
Product A5200.00Tax 15%1,000.00
Product B3150.00Tax 5%450.00
Product C1080.00Tax 18%800.00

⚠ Different taxes on each line — hard to manage!

✅ With Global Tax (10% GST)

One selection → all lines updated instantly.

ProductQtyPriceTaxesSubtotal
Product A5200.00GST 10%1,000.00
Product B3150.00GST 10%450.00
Product C1080.00GST 10%800.00

✓ Uniform tax across all lines — clean & consistent!

Purchase Order: Global Taxes Calculation

❌ Without Global Tax

Manually editing tax on 20+ purchase lines is tedious and error-prone.

✅ With Global Tax

Apply one global purchase tax and every line updates at once — even on orders with 50+ lines.

Real-World Use Cases

🏢 Use Case 1: Multi-Product Wholesale Order

Scenario: A wholesale distributor creates a sale order with 30+ products. All products need to carry the same 18% GST.

Solution: Select GST 18% in the Global Tax field → all 30 lines are updated instantly.

Result: Saved 5–10 minutes of manual tax editing per order. Zero errors.

📋 Use Case 2: Export Sales — Zero-Rated Tax

Scenario: An export order requires 0% tax on all lines, but products have domestic taxes configured by default.

Solution: Select Export 0% as the global tax → all default taxes are replaced with 0%.

Result: Correct tax treatment for export orders without changing product master data.

🛒 Use Case 3: Bulk Purchase with Unified Tax

Scenario: A procurement officer creates a PO with 40 items from a single vendor. The vendor charges a flat 12% tax.

Solution: Set Vendor Tax 12% as the global tax on the Purchase Order → done in one click.

Result: Procurement team saves significant time and avoids inconsistent tax entries.

Quick Start Guide

  1. Go to Apps → search for "Global Tax" → click Install.
  2. Open any Sale Order or Purchase Order. You will see a new Global Taxes field above the order lines.
  3. Select one or more taxes from the dropdown. All existing order lines will be updated automatically.
  4. Add new products — they will continue to get their default taxes (select global tax again to overwrite if needed).
