Individual Product Changes and Set-up
Step 1: Open the View/Modify Details Window for your designated Product. In our example we will be using a Tile Type product
Step 2: Navigate to the Pricing section and enable "Sell by" if you have not already
Step 3: Fill out SF price and have MeasureSquare automatically calculate your box prices with the Link prices icon, or skip this to input the box price directly
Step 4: Enable "use box unit in worksheet" to have Box quantities displayed, or disable to show Quantities in SF as in our example with our box of tile

Info: This toggle is shown using a Heart icon for enabled. You may have different container names and Units. Example LF and Pieces for transition strips.
