When I started selling my handmade jewelry, I was just as lost. Here's what I learned:
Wholesale pricing and sales tax are two different things. Wholesale is about getting goods at a cheaper price because you're buying in bulk. Sales tax, on the other hand, is something you'll have to charge your customers if your state laws require it. If you're in the US, the sales tax laws can vary from state to state, so it's best to do some homework on this.
Pricing items for profit was a challenge for me too. What helped was first figuring out the cost of materials and labor, then adding a markup for profit. It took some trial and error, but eventually, I found a sweet spot where my customers felt they were getting value for money, and I was making a decent profit.
Running a business is a learning curve, and there's always something new to learn. I found that reading up on various topics and connecting with others who had been there was a big help. It's great that you're reaching out and asking these questions!
When I was in your shoes, I realized that I was learning so much about the business that I decided to share my experiences in a blog. For a more in-depth look at these topics and more, you could visit here. It's packed with articles from my journey to building a few successful businesses.
