Youll would not recommend beginning to sell soap until one has been doing this probably a year or so?
My story...did a heck of a lot of research when I decided I wanted to make soap. Spent hundreds of hours watching YouTube videos, read hundreds of articles, researched the history of soap making (artesian and commercial), collected as many recipes. Made my first soap in June, was selling soap at a craft fair in November. It should be noted that I hadn't planned on selling soap at all, it just came about.
So anyhoo...had a blast at the craft fairs, sold a good 50 bars, was asked to participate in other craft fairs...I said no. Not because I didn't have enough soap (though that is what I said), but simply because I wasn't ready to sell soap because all the research aside and the several hundreds of bars of soap I had made...I realized that I really didn't know all that much about soap making.
That was two years ago and I have only recently felt that I am ready to sell to the public (which is not to say that I haven't been selling soap...friends, family, co-workers, and I have a wholesale account), but to sell soap to complete strangers???? Anyone can follow a recipe and still not know how to cook. And if you don't know how to cook, how do you know what the problem is if something goes wrong or how to potentially fix it? It's the same way with making soap...what do you do if your batter starts to 'rice', do you even know what causes it? Do you know the difference between emulsion and trace and why it's important? What is the difference between the various oils and butters and how do they contribute to your final product? Will you be advertising how moisturizing your soap is and how great it is for acne and eczema?
A lot of the mistakes I made I shouldn't have made, but I was in such a hurry to 'sell my soap'. Did you know that soap can shattered? It was the result of adding three tablespoons of dry TD to 33 oz of oils. But I was in a hurry and didn't realize that I was supposed to disperse 1 tea of TD in one tablespoon of water and then add 1 teaspoons of dispersed TD at a time. I will say that it was a beautiful white soap with a loverly orange layer and a pretty orange mica drizzel. LOL
I have two bars of soap that sit on my desk...one is the second bar I made, the second is from a year later. Both are made from the same recipe, but there is a marked contrast in the color and texture of the soaps. I have no doubt that if I were to add a recent soap, there would also be a difference.
The thing about soap making...you really have to make soap to understand how it is made. And you need to make soap every week at least to get to know how to make your soap so that it is constant...whether you are using 8 oz of oils or 80 ounces.
Then there is the business end...of running a business. Soap making is not cheap...I've spent around $4k over the last 2 1/2 years and I've been fairly measured about it. My soaping cart (aka rolling kitchen island) was my biggest single purchase, but it was measured too...if I decided to quit make soap, I can still use it in the kitchen. Same with the two shelving units, shelves, rack and drawers...all easily repurposed. Some of my mold purchases didn't work out which is why I only bought one or two at a time and most of them were purchased on sale. I'm still using the same Stick Blender and Scale. The only reason why I have a single-bar soap cutter is because I lucked out with someone selling theirs...elsewise I'd still be using my modified cheese slicer. But a good $3k...that's mainly base ingredients 'cuz I have made a lot of soap over the last 2 1/2 years.
Figure that you're going to spend a grand your first year on R&D (that's what I budgeted). Then you're going to need a business name and you're going to want to register it and you are going to need a website so folks can order soap or you can do markets and there is more expense there. And there is packing and labels and office supplies and don't forget insurance. Figure that it's going to take a good four years before you start seeing black ink.
