Accurate invoices are essential for maintaining customer trust and ensuring order details are clearly documented. When shipping charges fail to appear on WooCommerce invoices, customers may be confused by incomplete billing information and store owners may spend valuable time answering support requests.
Issue Background
A WooCommerce store discovered that generated invoices displayed product line items correctly but failed to include USPS shipping totals. Customers could see SKU pricing, but shipping charges were missing from invoice summaries.
Diagnosis
Investigation traced the issue to the Print Invoice & Delivery Notes for WooCommerce plugin. While order data contained the correct shipping information, invoice templates were not consistently rendering USPS shipping charges. This suggested either a plugin bug, template issue, or compatibility problem following updates.
Resolution Steps
Review the plugin configuration, update the Print Invoice & Delivery Notes for WooCommerce plugin, test invoice generation in a staging environment, verify shipping data is stored correctly within WooCommerce orders, and implement a custom mu-plugin workaround if invoice templates continue omitting shipping totals.
Before deploying changes, test invoice generation thoroughly and avoid sending test emails to customers by disabling outbound email services in staging environments.
Final Outcome
After correcting the invoice-generation process, USPS shipping charges displayed correctly alongside product totals. Customers received complete invoices with accurate billing details, improving transparency and reducing confusion during fulfillment and accounting processes.
