Can I reset an order number counter on a regular basis?
Yes, it’s possible with our Custom Order Number extension. There are 3 time periods available: reset order numbers each day, month or year. Moreover, you can choose not to reset the counter at all.
To choose the option which suits you best, please navigate to System > Configuration > Order Number > Order > Reset Counter on Date Change:
This setting is also available for Invoice, Shipping and RMA* numbers.
*RMA order numbers options are available for Magento EE users only. If you are using Magento CE, you can consider this RMA extension.
