Flower waste allowance: how many extra stems to order

Why waste changes your margin

A snapped stem, a wilted head or a damaged bunch was paid for like the rest. If your quote only counts the stems placed in the arrangement, every loss cuts your margin by the same amount.

Cost price is the total cost borne to produce and sell a service (Bpifrance Création, source below). Flowers bought and thrown away are part of it: they belong in your price, not only in your cash flow.

The three losses to tell apart

• On arrival: broken stems, damaged heads, uneven bunches. You see it when you open the boxes.
• During preparation: flowers that do not open, stems cut too short, trial arrangements. It depends on the variety and your skill.
• On the day: a stem to replace on site, touch-ups after transport. Cover it with a small reserve.

Separating the three stops you from inflating every quantity just to be safe. An on-the-day reserve is not calculated like the loss of a peony that never opens.

An allowance per variety, not one flat percentage

One percentage on the whole order overstates sturdy flowers and understates fragile ones. Sort your varieties into three families and give each a starting allowance.

These ranges are working guides, not industry averages: we found no official source that quantifies a florist's waste. Keep them until you have built your own records.

Worked example: a wedding order

In this example, the wedding arrangements need 350 stems. Purchase prices per stem and allowances are assumptions.

Cost of the stems needed: €543. Cost of the order: €640.50. The 55 extra stems therefore cost €97.50, about 18% more than the strict need, with allowances from 8 to 20% depending on the variety. Rounding to the bunch explains the gap: it weighs more on the eucalyptus (+25%) than the allowance itself.

Start from the right stem count before adding the allowance

Building waste into your price

Two methods work, and they should not be stacked. Either your markup on flower cost already covers waste (you measure it to check that it is enough). Or you price the recipe stems, then add a waste line or percentage you stand behind.

In the example, the €97.50 of extra stems is the provision to find somewhere in the quote. If it is not in your price, that amount comes out of your margin on this wedding.

Measuring to correct after every event

1. 1

   Record what you order

   Keep the quantity ordered per variety, with the allowance you had planned.

2. 2

   Count leftovers and losses

   After the install, count the stems thrown away and the stems left over, with a short reason: damaged on delivery, did not open, broken while working.

3. 3

   Compare with the forecast

   For each variety, work out the actual loss as a percentage of the stems ordered.

4. 4

   Adjust the family allowance

   After a few events, replace the starting allowances with your records. A variety that always exceeds its allowance changes family or supplier.

Two events are enough to start, but ten are better: a variety can behave differently depending on the season, the supplier or the heat of the day. Also note the date and supplier next to each record, so you can spot a problem batch instead of inflating everyone's allowance.

Seasonal flowers and those that travel badly deserve a closer check. For a variety you do not know yet, order a few more stems and test it before the day: the trial costs a few stems, while a bad surprise on the morning of the wedding costs far more.

Cutting waste without ordering less

• Check the boxes on delivery and report any defect to the supplier straight away, with a photo.
• Condition flowers as soon as they arrive: stems recut, clean water, rest in the cool before preparation.
• Use the most fragile flowers first for the most visible pieces, and keep sturdy ones for fillers.
• Reuse surpluses: trials, thank-you bouquets, next-day arrangements. A useful surplus is not a loss.
