Specialized software requires you to fully understand your data structure before you begin using it. You must define fields, set permissions, and establish relationships upfront.

Professional versions allow users to save HTML input files for future use, bridging the gap between a static Excel file and a dynamic web application.

One of Li’s golden rules is that numbers should only be typed once. If a formula multiplies a cell by a tax rate of 0.15, that 0.15 should not be written inside the formula. Instead, place the tax rate in a dedicated "Assumptions" cell on the input sheet and reference that cell. This ensures that if the tax rate changes, you only update it in one place.
