reset / change invoice number

Hi all,
I've not found anywhere a way to reset the invoice number.

Every Year I've to reset the invoice number back to 1.
(the order number may be anything I want)

Sometimes I've people who buy from me and I emit an invoice to them (with products not in my shop), so the ideal would be a way to
reset it on every year (and a way to reserve some numbers when I need to write an invoice extra the online shop)

It is not possible to re-set the order/invoice number BACKWARDS.. ie: to a number LOWER than that which currently exists.

You can set it FORWARD to a higher number, but not to a lower number - so it's not possible to re-set it to "1" as you request.

Also, accounting protocol (if you follow it) does not allow duplication of order numbers - for obvious reasons. A number has to be unique to the order, so that can never be any error in associating accounting records and documentation with a physical transaction.

The system in ZC is purely arithmetical - it increments the number upwards for each successive transaction.

What you may consider doing is setting your number each year to an eight or nine digit number (depends on how many orders you take annually, but if it's under 10,000 you could set your increment each year as follows:

For 2009, start the incrementation at 20090001
For 2010, start the incrementation at 20100001
...etc
