Fixed Price Invoicing: With Pro-rata

The Invoice with Pro-rata routine operates in a similar manner to the Invoice with Under / Over Recovery in that it allows the user to determine the value that the invoice should be raised for, either based on the quoted values of the Job, or based on a user entered value.

However, the way the system deals with the difference between the Ready To Process Total and the user entered invoice value differs, in that, with the pro-rata routine, the system will change the unit selling price after discount on each of the Job line included in the invoice, until the total value of the Job lines equals the invoice value entered by the user.

With this routine, the write up / off is attributed back to the transactions that make up the Job, rather than only to the Job.

This routine is most commonly used when transactions on the Job are predominantly staff related transactions. In this way the company is able to apply the write up / off to the individual staff member and report on what the true recoveries are for the staff member.

The pro-rata calculation is based on the contribution that each line provides to the initial invoice value. The system uses the percentage contribution that each line makes to the initial system calculated invoiceable total and applies that percentage to the user entered invoice value to determine the lines new value. Frequently, using this routine, rounding imbalances arise which the system cannot pro-rata. These imbalances should be vary small amounts (a few cents) and will be included in a rounding line that the system will insert onto the Job to balance the value of the lines to the value of the invoice total. Where a rounding line is inserted the following details are used:
