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
- Add products to your Sale Order or Purchase Order as you normally would. Each line gets its default product taxes.
- Select Global Taxes in the new field above the order lines. Choose one or multiple taxes from the dropdown.
- All eligible lines update instantly. The selected global taxes replace the default taxes on every non-invoiced line.
- Totals recalculate automatically. Subtotal, Tax, and Total amounts reflect the new global taxes.
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.
| Product | Qty | Price | Taxes | Subtotal |
|---|---|---|---|---|
| Product A | 5 | 200.00 | Tax 15% | 1,000.00 |
| Product B | 3 | 150.00 | Tax 5% | 450.00 |
| Product C | 10 | 80.00 | Tax 18% | 800.00 |
⚠ Different taxes on each line — hard to manage!
✅ With Global Tax (10% GST)
One selection → all lines updated instantly.
| Product | Qty | Price | Taxes | Subtotal |
|---|---|---|---|---|
| Product A | 5 | 200.00 | GST 10% | 1,000.00 |
| Product B | 3 | 150.00 | GST 10% | 450.00 |
| Product C | 10 | 80.00 | GST 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.
📋 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%.
🛒 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.
Quick Start Guide
- Go to Apps → search for "Global Tax" → click Install.
- Open any Sale Order or Purchase Order. You will see a new Global Taxes field above the order lines.
- Select one or more taxes from the dropdown. All existing order lines will be updated automatically.
- Add new products — they will continue to get their default taxes (select global tax again to overwrite if needed).
