Piece type and piece rate options become available after 'Piecework' has been selected as the job's pay type.
The first drop-down lets you select which piece type will be used in the Job (Bins, Buckets, etc...). This option is required. Each Job may have up to two different piece types*.
If two piece types are selected for a single Job, they must be different. For Jobs that have the same piece type, but different piece rates, two separate piece types must be created. i.e. 'Bins 1' and 'Bins 2'. Each can then be given different piece rates.
The second option allows you to specify the piece rate, which is what workers will be paid per piece.
