Use WooCommerce coupons as PDF vouchers to increase sales in your e-commerce store. Today, I’m going to show you some useful tips for managing PDF product vouchers and customizing such coupons in WooCommerce with a plugin. If you’ve been wondering how to display the variable product name on a voucher, how to display a column of coupon numbers on the order management page, or how to generate multiple coupons within a single order, this is the article for you.
Customize PDF Coupons in WooCommerce
In this article, you’ll learn how to customize the Flexible PDF Coupons – Gift Cards & Vouchers for WooCommerce plugin. The below tips will help you adjust the plugin to your needs and offer your customers beautiful PDF product vouchers in your WooCommerce store!
Customizing WooCommerce PDF coupons often comes down to small details that make a big difference in how professional and trustworthy your vouchers look to customers. A generic, unbranded coupon can feel like an afterthought, while one that correctly displays the right product name, variation, and order details signals that your store pays attention to the experience — not just the transaction. The customizations below address some of the most common gaps between the plugin’s default behavior and what a polished, ready-to-send voucher actually needs.

Variation names on the voucher
What would you say if a customer ordering a voucher from your shop could see a variable product name on the PDF printout? It’s easy if the WooCommerce voucher product has one distinctive variation attribute. The difficulty begins when the product has more attributes. In this case, the voucher will only have the main product name. Let’s try to customize coupons WooCommerce by modifying your shop
You can change this by modifying the display of attributes in WooCommerce orders. WooCommerce displays the full name of the variation in the order entry, i.e. with the attribute in the title, by default. However, if there are more attributes, they will be displayed one below the other in the order as follows:
T-shirt – size M
colour : white
The WooCommerce voucher will only have the product name, with no indication of the variation. If you want a specific variation to be displayed on the Voucher as well, follow these three steps:
- add the filter to functions.php
- specify the default variant, i.e. do not leave the option Any
- if the attribute name has more words, change the slug in Products→Attributes→Edit→Slug settings to one without a dash
The final result in the order will be as follows
T-shirt – size M, white
The voucher will look as follows 😉
How can coupon numbers be shown in the order panel?
This handy solution allows you to quickly look, which WooCommerce PDF product vouchers code has been generated for a specific order.
This is useful, especially when a customer wants to know more about a voucher code, and you need to get the right information quickly as well. Clicking through multiple orders is a recipe for your customer’s communication chaos. Especially as, for example, the order number, and the coupon code can be available in one panel.
How can you achieve this? All you need to do is modify your WooCommerce a bit. Add the filter below to the functions.php of the current theme you are using in your store.
That’s all. A quick change, but how useful 😉
How can I generate several coupons in one order?
It’s time for one more snippet that will allow you to generate multiple coupons in a single order. If you purchase multiple vouchers within a specific order, the Flexible PDF Coupons WooCommerce PRO plugin will generate a single coupon for the value of the vouchers purchased. If you want to generate multiple coupons within one order, use the following filter in your functions.php file.
Before applying any of these snippets to a live store, it’s good practice to test them on a staging environment first. Since each customization modifies functions.php, even a small syntax error can affect your entire site, not just the coupon display. Testing on staging also lets you place a few sample orders and confirm the voucher looks exactly as expected — correct variation name, visible coupon number in the order panel, and the right number of generated coupons — before customers start seeing the result.
That’s all. The snippet is added, so multiple coupons will be generated in one order.

FAQ
Can I customize WooCommerce PDF coupons without coding?
Some customization, like coupon design and layout, can be done through the plugin’s built-in editor. However, the specific tweaks covered in this article — showing variation names, coupon numbers, or generating multiple coupons per order — require adding a filter snippet to your theme’s functions.php.
Will customizing PDF coupons work with any WooCommerce theme?
Yes. The snippets modify how WooCommerce and the plugin display and generate data, independently of your theme, so they should work regardless of which theme your store uses.
Do these customizations require the PRO version of Flexible PDF Coupons?
The variation name and coupon number snippets work with the free version. Generating multiple coupons in a single order specifically requires the Flexible PDF Coupons PRO plugin.
