Documents customers and warehouses need.
WHAT WOOCOMMERCE PROVIDES
Order confirmation emails, and a customer invoice email you can send manually from the order screen.
It does not produce PDF invoices or packing slips by itself.
ADDING THEM
A PDF invoice plugin attaches an invoice to order emails and lets you print packing slips from the order screen.
Most offer templates you can brand with your logo and business details.
WHAT AN INVOICE SHOULD CARRY
Your business name and address The invoice or order number and date The items, quantities and prices Tax shown separately if you charge it Payment method and status Your contact details
PACKING SLIPS
A packing slip lists items and quantities without prices, for whoever packs the order. Printing these in bulk from the orders list saves considerable time at volume.
FOR BUSINESS CUSTOMERS
They will ask for a proper invoice. Having one ready avoids a manual request each time.
PRACTICAL POINT
Test what the PDF looks like before launch. Default templates are often ugly and carry placeholder details.
