Stop quoting from an average price
Most spreadsheets compute the cost of a wedding bouquet from an average wholesale price. That hides a problem: the flowers you'll buy for the wedding may be 30% more expensive. The margin you promised on the call evaporates by the wedding.
Quote from your own recipes
Build each arrangement as a recipe — every flower and quantity. The system multiplies the recipe by the count, takes prices from the studio's purchase price list and adds your markup to get the client price. You see margin per line and per project before you send.
Make the proposal look like you, not Pinterest
A live presentation with your logo, a palette pulled from the moodboard and zones works better than a PDF clone of someone else's mood board. The client opens the link on the phone and marks each block: "like" or "want it different" with a comment.
From approval to order
The client signs the proposal with a simple e-signature, and the manager gets a Telegram notification. Starting the project creates the order, and project finances show plan vs actual. Nothing retyped, nothing lost.
