Don't mean to start a fight, but sorry to say talking about Margin Contribution as your guys are doing is like talking about dropping your loose pocket change into a glass jar at the edge of your bed every night and telling yourself that someday you hope to take your dream vacation when the jar gets filled. I agree with Mark on this subject and most florists will never see any positive results for their business, especially a NEW business based on marginal contribution.
There was a time when margin contribution was viable factor. Florists used to meet their monthly "bogey" numbers by the 20-25th working day of the month and everything after was almost pure gravy <Profit>. However, times have changed and so has the way that many florists have to look at how they keep score. If I read Joe and Preston closely, they are saying that every dollar counts and even if incoming wire orders doesn't meet your full margin goals, it's OK because those couple dollars that you make off each order can be used to help pay your fixed labor costs. I'm sorry, but this is an old economic concept that florists have been using for years to find ways to keep the designers and drivers busy. As a small business person, you have other choices and one of them is reduce your monthly "bogey" number. In other words, have less designers or work them less hours. If you were in the clothing business, traditionally you would have SALES all the time to move your inventory. Clothing merchants were always willing to take LESS dollars for the merchandise to get it off the books. Many clothing retailers today, however, are seeing that it is better to buy less merchandise and have less sales and make more profit. Many of us florists are finding that by cutting some expenses, we are actually making more profit from less business and paying our bills.
As a florist, you can mathematically determine that if you join a WS to send out orders, you have just created an added "fixed" cost of $xx per month and the commission gained by this venue may be totally eaten up by these monthly costs. On the other side, the incoming discounted orders may provide marginal contribution as has been indicated, but in small doses which is what most small florists experience, and there is not enough CONTRIBUTION there to tip the waiter at McDonald's when you go to lunch.
If florists followed the idea of marginal contribution to it's fullest, joining one WS for incoming would be good, joining 2 WS would be better and joining all 3 would be GRANDEOSO. The MAJOR problem most florists face today is not being able to generate enough full margin business to pay their bills and it is foolhardy to try to suppliment this shortage of full value business with discounted business which has added fixed costs attached to it. What changed the idea of marginal contribution? The addition of grocery stores into the flower business and "flowers in a box" and lastly and most important, the increasing numbers of OG's. All of these factors are geared to reducing the amount of full margin business available to the local florists.
As one florists told me the other day when we were talking about all the mutual problems of the industry and I asked him why was he still in the industry, he responded, " it is very easy to get into being a florist, but very difficult to get out with your hide intact"!
