ServiceBox does not automatically generate a Purchase Order(P.O) number however since there is the option to track P.O's in the Work Order, the information can be stored for jobs that are in the system.
For example: If you are in Work Order #1549, and you need to generate a P.O. number, we suggest starting with P.O. # 1549-1, and record this in the P.O. # category on the Work Order in the description field.
You will have to give this P.O. a value, even $0 until you know the actual value of the P.O. Once you know the value of the P.O., you may choose to record the actual value of the P.O. in the line item of the P.O. category that corresponds to it, or break out the P.O. items individually, and record them in the Materials category of your Work Order. This is based on how your company decides to handle the materials for the job.
When you transfer the information for a Time & Materials invoice from ServiceBox into accounting, the values will be transferred over, along with the P.O. # on the line item.
