Order the extras to have all your work done for you to enter your own personal recipe into the cost calculator and have it saved and sent to you. All you need is your soap recipe, and a basic gig order to add this option on. You can even add websearch to the order and I'll put the lowest prices and sources I'm able to find into your personalized recipe. You can compare what you already buy with those numbers.
I hope to support the success of your business with this tool which helps prevent losses in your business
