vintrace offers you the flexibility to define your own operation types as Treatments and then use these as part of stand alone work orders or any transfer or addition.
A classic example of a treatment is a Cross flow filtration. You can write a work order to cross flow a wine by using a Treatment and any of the Transfer functions combined.
To set a cost against that treatment, either by Volume or Fixed, you can create a custom cost item under Winery Setup > Costing > Cost item.
The Price per for these instances will either be Per Gallon/Per Litre or Each. The Each option is for fixed costs.
You can now link this to your treatment under Winery Setup > Treatments > Treatment (Product).
Note that you can override the default cost value.
Each time this treatment is applied to a wine the cost impact will be recorded.
