How to handle retainer billing
If you have retainer billing arrangements with clients, you can use features in TimeCache to make it easier to apply your time and expenses to a retainer.

TimeCache has a Retainer billing category type that lets you create entries that account for a retainer amount. Then you can apply time and expense entries to a project/matter's retainer. TimeCache can show you each project's retainer totals, and highlight your billings as a project's charges approach the retainer amount.

When you add a Retainer billing category item to the Daily Log, it is shown in bold type, and the Hours column shows an "R". If you set TimeCache Preferences to show entries applied to a retainer in a color you define, they will appear in that color. Their charges will show in the Charges column, but will not be added to the total charges at the bottom of the Daily Log.
