Stem & Sum puts a wedding florist’s numbers in one place
A desktop-browser tool for independent wedding florists to build quotes, calculate costs and profit, and prepare supplier-ready flower orders.
Field notes
The workflow starts with flower recipes, bunch sizes, supplier costs, and arrangement quantities, then adds labor, delivery, and other business expenses to produce a quote and planned margin. Its purchasing view converts recipe quantities into full bunches, includes extra stems, and can print orders by supplier. The sample event covers 80 guests and separates a $1,606 flower-and-hard-goods cost from $930.83 in labor and event costs.
