By using WebToffee’s PDF Invoices & Packing Slip plugin for Woocommerce on your store site, you can match the invoice number with the order number in only a few steps.

• First of all, install and activate the plugin, a new menu Invoice/Packing appears in the WordPress dashboard.
• Head on to Invoice/Packing > Invoice menu. The invoice settingswindow will open up.
  OR
• Go to General Settings > Documents tab > Invoice > Settings.

From the invoice settings window, go to the Invoice number tab.

You can set up a custom invoice number with prefix/suffix/number series or even mirror the order number as invoice number respectively.

• Invoice number format: Choose [number] from the format to have the invoice number without prefix or sufix. To have prefix or suffix, you can choose an approprate option from the drop down as shown below:

Invoice Length: Indicates the total length of the invoice number. If the length of the generated invoice number is less than the provided, it will be padded with ‘0’. E.g if you specify 7 as invoice length and your invoice number is 8009, it will be represented as 0008009 in the respective documents.
