I LOVE DOING HOME PARTIES!!! It's my absolute favorite way of doing business! I make more than just bar soaps, and women seem to really like the fact that i will come to their home, let them try it out, smell all the scents, and make their own "custom" washes and soaps.
I do it very, very simply. I find a host who wants to earn free products or just needs entertainment for a get together. I come to her home and help her set up. We play music, set out some healthy snacks (health is a big pillar within my personal life and company) and mix up drinks. I do a small presentation about my company and why it's better than store bought. I let them know it's that cheaper, paraben and formaldehyde free, local, empowering for women, and we create jobs within the community. I also talk about some of the properties of the ingredients that I use like essential oils. I finish with a quick run through of the products. Next we do samples, give facials, mini manicures, ect using the products. This is where my sales comes in. I make recommendations, give suggestions, or just little tips and tricks. I finish with taking orders and offering "custom" washes and soaps. My custom washes and soaps are simply base formulas with extracts, fragrance, and additives added per the consumer. You can make those at home, or you can make a base and do it at the party. Its a fun little activity. The whole deal can take an hour or two, just depending on what the host wants, either quick and simple or a full blown girls night.
As far as sales, I do cash and carry as well as take orders. I process credit cards through Square. Usually, people love that and think its awesome they can just sign with the finger and have a receipt texted or emailed to them. I provide a hostess gift as well like travel size body wash and lotion, or maybe a facial kit. It depends on the size of her party. I offer sign ups for anyone else who wants to host a party to earn free products. I'm going to try to work on a website now that allows hosts to have online parties as well.
I hope this helps, and I hope you find a lot of success in this aspect of sales. Its so much fun!
