After you collect payment from your customers, you will pay your avon bill. What you have left over from this amount is your payment.
Avon only requires you pay a percent of the sales (depends on your sales level). You collect the FULL amount and keep the difference. For example- you sell a lip balm for $1. You collect the $1 (plus tax of course). Avon will only ask you for .60 cents (if you are earning 40%). Hence you keep .40 cents. That is how you make your money.
You collect money from your customers and keep the percentage left over. You can join Avon in the UK at http://www.applyavon.co.uk
I sell Tupperware. After market research I decided it was easier than Avon
