This relates to v4.3 style only.
As it is common for a contract to have standard, unders and overs billing, it is necessary to set opening balances for each of these values. This is performed by setting an opening balance for the stock assigned to the particular charge type. A typical photocopier would only have an opening balance set for the stock of its standard meter.
Using the above example, go to the Open Balance tab at the bottom of the form.
This allows the black meter and black service meters to have independent opening balances. For these two meter types it has little practical impact, as service reads are always charged at $0.00, but it does become more important when unders and overs stock are assigned an opening balance.
Jim2 tracks average or estimated reads for contracts using Unders stock. This means that a simple cost per copy contract setup that allows averages may look similar to this:
If this contract was being created in Jim2 for the first time, and had previously had a recorded read of 40,000 black pages, and a subsequent estimated read of 10,000 pages, set up its opening balance tab as follows:
The inclusion of a price for the Unders is only required where either of the historical rates of clawback are used (ABH, OBH or AUH, OUH). If either of the current methods of clawback is used (ABC, OBC or AUC, OUC), then only the page count is required. If supplied, the read/purchase date indicates the last time a read was performed. The above grid shows an actual read was recorded on 1st July, but an estimate was supplied the following month on 1st August.

When adding an Overs opening balance, a warning that the suggests value might be incorrect will appear:
