Advanced WooCommerce customizations for invoice automation, QR-based workflows, and role-based store management.
This case study demonstrates how WooCommerce can be extended to meet specific business requirements. The project included:
- Custom invoice templates for thermal printers
- QR-based order completion flow
- Granular role-based permissions for actions and visibility
- Exportable reports (PDF/Excel)
- SKU auto-generation for new products
- AJAX-based workflow updates and restrictions
These enhancements improved security, efficiency, and operational control for a Colombian client’s WooCommerce store.
-
🧾 80mm Invoice Template – Custom WooCommerce invoice template designed for 80mm thermal printers. Displays full order, shipping, and payment details along with a scannable QR code for storage validation.
-
📦 Automatic SKU Generator – Automatically assigns SKUs to new orders or products without one. SKUs are dynamically generated based on the selected category, or a default format if no category is assigned.
-
💫 Conditional Pay System – Adds a custom payment status selector visible only for four “home delivery” shipping methods. Allows choosing between Paid or To Collect.
- When “To Collect” is selected, it enables an amount input and currency selector (COP/USD).
- These details are reflected in the invoice PDF under the shipping section.
- Orders cannot transition to another status unless a payment condition is selected.
-
📱 QR Scanning Workflow – Allows users with the Storage Manager role to update order statuses (e.g., Printed → Completed) by scanning the QR code on the invoice — no admin navigation required.
-
🧾 Shipping Report Generator – Adds a WooCommerce submenu to generate PDF shipping reports.
- Filter by country, shipping method, and date range.
- Produces a thermal-format PDF (80mm) showing all order IDs for the selected method, including each order’s shipping cost.
-
🔐 Role-Based Restrictions – Defines strict access rules for specific user roles:
- Storage Manager: Can view and manage orders in Processing and Printed states only.
- SEO Manager: Can view and manage orders in Pending, Reserved, and Completed states only.
These limits apply to quick actions, bulk actions, preview visibility, and edit access, ensuring that each role interacts only with relevant orders.
Automatically generates SKUs based on product category or assigns a default SKU when no category is selected.
Custom 80mm invoice layout showing order, shipping, and QR details for fast thermal printing.
Shows the chosen payment condition (Paid or To Collect) directly in the invoice PDF.
Prevents order status changes until a payment condition is selected.
Allows Storage Manager users to mark orders as Printed or Completed by scanning the QR code from the invoice.
Generates compact PDF shipping reports filtered by country, method, and date range — displaying all relevant order IDs and their shipping amounts.
Displays how each role sees only the orders and actions permitted by its configuration — ensuring clean, secure, and role-specific workflows.
