Show accurate shipping charges and the total order cost at checkout in OpenCart. Configure shipping charges by location (country, geo zone, zone) and order criteria (currency, language, store, customer group) so totals match each customer’s context.

How does it work?

• Create rules in the Charges tab. Each rule contains a Title and a charge value.
  
• Enter charges using the admin format From, To, Cost, and optional For. You can omit For and also omit From or To when limits are not needed.
  
• Build flexible shipping rules by combining:
  location criteria: country, geo zone, zone
  order criteria: currency, language, store, customer group
  
• Apply adjustments: charge adjustments, min charges, max charges, rounding, tax class application, total cost logic.
  
• Use Sort Order to define rule priority when multiple conditions match. Rules with higher priority are applied first, allowing precise control over how shipping charges are calculated.
  
• Temporarily enable or disable rules using Show and Hide, or bulk actions Show All and Hide All.
  
• Verify checkout results using Testing Mode logs.
  
• If needed, revert configuration using Backup Settings and Restore Settings. Optional Automatic Saving can be enabled.
