WooCommerce Sequential Order Numbers Pro
Get Professionally Formatted Order Numbers for your WooCommerce Store
The WooCommerce Sequential Order Numbers Pro plugin allows your store to have sequential, rather than random order numbers. Additionally you can customize your order numbers by setting a starting number, number length and custom prefix and postfix. Instead of your order numbers skipping values (like 15, 37, etc), they could be for instance WT-01000-UK, WT-01001-UK, etc, or whatever format you prefer.
