Budget Planner is a whole-farm or enterprise budgeting software program that is simple to use for farmers, extension agents, and other budgeters who are sometimes inexperienced, but that also provides the detail necessary to be accurate. Program defaults eliminate repetitive questions that change little from budget to budget. Defaults can be temporarily overridden, or they can be permanently changed with a detailed modify program. The program leads a user through a sequence similar to that a producer might utilize. Input forms were created to enlarge the user clientele and eventually increase computer use by farmers and extension agents.
