Your order / invoice numbers can contain running counters and many variables, including:
- Year, month, day, time
- Country of the customer
- Random letters or digits
- Any fixed string
- Invoice numbers can be set equal to the order number

Endless possibilities to have order/invoice numbers the way YOU like them

Whether you want simple order/invoice numbers with a prefix, or whether you want the invoice number to match the order number, or whether you even want separate number counters for each country or even customer, OpenTools Advanced Order Numbers for VirtueMart is the solution you need!
While the order/invoice numbers might be just a nuissance to your users, using clean, professional numberings will give your customers the assurance that they are dealing with professionals - the small, subtle details are the difference between a good shop and an excellent shop. Rather than showing confusing order numbers like 0b4c011 in VirtueMart's default format, use a clean numbering scheme like "2015-011" or "INV-01/0023"!

Easy configuration, yet powerful features

Key features of this module:

• Freely customize order numbers, invoice numbers, customer numbers and/or order passwords to your desires!
• Number format is given as an ordinary string that can contain a vast number of variables (date/time, order properties, customer properties, address, and even random numbers or letters) and a counter
• Customizable counter resets, multiple parallel counters: Counter can be global (one counter for all orders or invoices) with no reset, or yearly/monthly/daily counters, or even more general counter resets. You can even have multiple counters running concurrently (e.g. one counter per country, or different counters and thus different order/invoice numbers for wholesale and retail customers).
• Alternatively, you can re-use the order number as invoice numbers, too (in some jurisdictions this might be problematic, because the order numbers can have gaps!)
• Counter formatting: In addition to the number format, you can choose the padding of the counters with zeros on the left (e.g. a counter with value 35 can be displayed as 000035 inside the number format)
• Manually set/change your counters in the module configuration

The exotic...

The incredible flexibility of this VirtueMart plugin means that you do not have to stop at the usual numbering schemes involving a counter. You can even use only the date/time of the order or even random numbers as order or invoice numbers.

Please note that in many jurisdictions there are certain restrictions on invoice numberings (mostly that they have to be / include an increasing number, and that they have to be unique). So the random invoice numbering scheme shown above would not be legal e.g. in the European Union. Just because this module gives you the possibility to choose such invoice numberings, does not mean they are legal everywhere.
On the other hand, to our knowledge, there are no legal restrictions on order or customer numbers, so you should be free to use any numbering scheme for these.
