If you’re running a WooCommerce store, offering discounts through coupons can be a great way to encourage repeat purchases and attract new customers. Although there are plenty of plugins available for coupon generation, it’s entirely possible to bulk generate coupons directly through WooCommerce without using any additional plugins. In this guide, we’ll walk you through how to generate multiple coupons in WooCommerce using custom code snippets.
By using the WooCommerce built-in functions and a bit of custom code, you can save server resources, avoid potential plugin conflicts, and streamline your coupon management process. Follow along as we show you how to do this with ease!
Why Generate Coupons Without a Plugin?
- Avoid Bloat: Plugins can slow down your site, especially if you have many installed. Generating coupons manually with code allows you to keep your site lightweight.
- Full Control: Custom code gives you the flexibility to tailor the coupon creation process exactly to your store’s needs.
- Enhanced Performance: Using built-in WooCommerce features ensures better performance compared to relying on a third-party plugin.
Custom Code to Bulk Generate Coupons
The following code snippet will allow you to bulk create WooCommerce coupons with custom settings like discount type, amount, expiry date, and more. All you need to do is add this code to your theme’s functions.php file. Always remember to use a child theme when adding custom code to avoid losing your changes when the theme updates.
