"Does this save my plans?"
Most of “the numbers” you might want to save – that is, your Monthly P&L – are generated by the PROFITS Center calculators based on the few entries you input (planned sales and margins, etc.)
The best way to "save" those, once you have developed a plan you like, is to just print out a hard copy for reference. Do that by using the “PRINT ALL“ button.
In fact, depending on your computer and/or browser, you may be able to simply email a pdf copy of the plan.
