Florist Bookkeeping: How to Track Perishable COGS Without Going Broke

By Victor Schiano, Founder of GuidedLedger | 7 min read

Most florists' margin numbers ignore the stems that never sold. Here's how to fix perishable COGS and finally know your real gross margin.

The single biggest reason small florists struggle isn't price or competition — it's perishable inventory math. If your books treat $1,000 of wholesale flowers as if every stem sold, your margin number is fiction. The truth is closer to $700 of usable product after dump, design waste, and shrink, which means you've been pricing arrangements based on numbers that were always wrong.

Why "Wholesale Cost = COGS" Is Wrong

Cut flowers are perishable. A meaningful percentage — usually 15–30% — never makes it into a sold arrangement. They die in the cooler, get cut down during design, or end up in a giveaway. If you book the entire wholesale invoice as COGS, your gross margin includes the stems you sold and the stems you threw out. That distorts every pricing decision you make.

The Right Way to Book Floral COGS

You have two practical options:

  • Weekly inventory adjustment: Each week, estimate dump and design waste as a percentage and book it as a separate "shrink/dump" expense line. COGS reflects what actually went out the door.
  • Standard waste percentage: Apply a baseline waste rate (say 20%) to wholesale purchases and adjust quarterly based on actual count. Less precise, but workable for very small shops.

Either way, you stop hiding waste inside COGS and start managing it.

Seasonal Cash Flow: The Real Killer

Valentine's, Mother's Day, and wedding season pay your bills. The weeks between can be brutal. The fix is mechanical: each peak-week deposit gets split between operating cash, a slow-month reserve, and a quarterly tax reserve. Done consistently, January and August stop being scary.

Wedding & Event Deposits Are Liabilities

A $4,000 wedding deposit booked six months out is not revenue — it's deferred revenue. Recognize it when the event is delivered. Otherwise your tax bill and your per-event margin are both wrong.
