Re: Order ID start at 001
There's no quick easy built-in way to do that.
However, a workaround would be to use the Admin->Tools->Store Manager to set the next order number to 101, which is naturally 3 digits, and start from there instead of 001.
Re: Order ID start at 001?
Not in the database; the order id is a numerical auto-incremented value. But any place you want to use the order id for non-numerical purposes, you could edit the display as a string so it showed with minimum 3 digits, padded with zeros if necessary.
Re: Order ID start at 001?
What happens when you finish processing order number 999 ?
