Details
The default numbering system of Magento is very straightforward, but rather inconvenient, creating titles like 100000001, 100000002, and so on. If you have, or forecast to have, a relatively large number of orders through your store, this system might create unnecessary troubles for your order processing, accounting and customer support.
The Peexl Customer Order Number Magento extension will allow you to adapt the numbering system to the internal needs of your store. It allows full flexibility in number generation for orders, invoices, credit memos and other important information.
