Set Custom Order Number Formats in WooCommerce
Custom Order Numbers for WooCommerce replaces the default WordPress Post IDs with structured and meaningful order numbers. You can define order sequences that match your business needs using letters, numbers, dates, or custom fields. Create formats like WT195, ORD1001, INV2025, or STORE0501 with just a few clicks.
The extension allows you to generate sequential order numbers, apply custom sequences, or reset numbers automatically. You can update existing orders or apply changes only to new ones, giving you complete control over WooCommerce custom order numbers and ensuring clear order tracking across your store.

 Customize Your Order Number Sequence in WooCommerce
Easily manage your order numbers sequence in WooCommerce by creating a clear sequential order that reflects your store workflow. You can add custom prefixes or suffixes, such as WT or EU, to identify departments or regions. 
You can also set a custom starting number, for example 1000 instead of 1, which is helpful when migrating from another platform or extension. 
These customization options make it simple to define order numbers that follow a logical sequence while also meeting internal or legal requirements. Standardizing your order numbering using the extension helps improve clarity, ensure consistency, and simplify order tracking.

Choose Custom Increment for WooCommerce Order Numbers
Not all stores want consecutive order numbers increasing by 1. With this extension, you can define a custom increment value for your sequential order numbers. Whether you want to increase order numbers by 5s, 10s, or any other interval, the extension gives you complete control.
Example: 
Instead of #1001, #1002, #1003, you can generate #1005, #1010, #1015, and so on.

Reset WooCommerce Order Numbers Automatically
Choose how often your WooCommerce order numbers reset, whether daily, monthly, or yearly. This helps stores organize orders by time periods, such as quarterly reports or financial cycles, and also keeps order numbers shorter and easier to manage.

Use a Separate Order Number Sequence for Free Orders
This WooCommerce sequential order numbers extension lets you maintain a separate order number sequence for free orders, giving you better clarity in tracking and reporting. By separating paid and free orders, you simplify accounting, improve business insights, and avoid confusion when reviewing sales performance.
 
Example:
<ul>
<li>Paid Orders: ORD-1001, ORD-1002</li>
<li>Free Orders: FREE-0001, FREE-0002</li>
</ul>
