Parsley's Ordering section lets you to enter forecasts or events, and then order the ingredients for one or several of them. Ingredient ordering can be done by printing out the order, or by emailing it directly to your supplier. If you email an order, a copy of that email sent directly to you.
Forecasts can be your Pars for each day of the week, while events would often have a pre-determined sales quantity, for example a business dinner, a catering order, or a wedding reception. They are both entered in into Parsley in the same way, by going to your Ordering page, and clicking on "New Event or Forecast"
You can then order for each forecast or event separately, or you can order for multiple forecasts (for example, the pars for several days, or for several events, or for a combinations for daily pars and special events) simultaneously.
