Did the seller give you these financials?
They look pretty wacky to me.
I used to own and operate 13 greenhouses and a flower shop, along with my wife.
She's still in the business, but not ours.
First, I assume you're talking bedding plants and vegetables, not cut flowers.
For the holidays, you're probably talking bulb crops (lilies, tulips, hyacinths) at Easter, pot mums and hanging baskets for Mother's Day.
Here are some problems...
I assume you're a bit more temperate than we are. We always had a problem with the bulb crops "blowing" at Easter. They HATE the heat. We had big walk-in coolers to store them in until we were ready to re-stock (several times per day). Without those, the shelf life of a tulip might be as short as 1-2 days in the heat.
Next, I don't see water expenses. Our greenhouses were on a well and pump
system. It sounds like you might be in a city water area. You'll go through a lot of water with these plants.
I also see a problem with the spread of sales week-by-week. Easter sales are usually OK, but they were better in the old "Family get-together" days. It would definately be a bigger weekend than average, but not huge.
In most areas, there is a locally known "frost-free" date. In our area, that was Memorial Day. The week leading up to that day was always HUGE compared to others.
Mother's Day is another BIG day. Not so much the week of, but the Saturday/Sunday of. You'll need lots of stock and help for that weekend.
I'm not sure how Memorial Day sales would be in your area. Up here, it was big. But that's when everyone was buying vegetable plants, as well as flowers. The actual purchase of flowers or what we called "Combo Pots" for the cemetery, were limited.
Finally, the end-of-season is a killer. It seems like you'd just be selling off inventory. But what you'll find is that the plants at that point are overgrown, yellowed, missing leaves, and overall pretty ratty. So, not only does the volume drop, but the price plummets. And at the end, you'll likely need to toss about 1/3 - 1/2 of the stock from a couple of weeks earlier...it just won't all sell.
On the good side, when the economy was bad, flowers sold well. People don't travel, so they spend time at home. Gardening is a beneficiary of that. Likewise, many people will plant vegetable plants to offset food costs.
One final thing...a plant stand is like a farm. You can't ignore it. An hour delay in watering can cost you dearly in dead plants. A late-season frost can be devistating. Not having shade for shade-loving plants can kill them. There is no day off.
Similarly, a wet season can kill your business. Think what will happen if it rains heavily on Easter, Mother's Day, and another peak weekend or two. The stock will rot. Customers won't show up. But the bills still will. There isn't much you can do about it, but it still needs to be factored in -- sort of like vacancy in
real estate.
What sort of inventory are they selling you for $10,000? Bagged soils, fertilizers,etc? (UV destroys those bags in a season.) Post a bit more about this item, if you could.
