How I can charge clients I got from the Wix marketplace? should it be through Wix billing or Paypal? Also should the client pay before or after the project is done? Also, what are things I can do to protect myself?
So, there is a lot here. Let’s unpack this a little.
Paymnent Methods to Charge Clients in the Wix Marketplace
Wix does not enforce any particular method. This is up to you. Many partners use PayPal, Stripe, and Wix Payments. Most take credit cards, some require bank transfers. This will be up to you and your practices.
When to Charge Clients for your Work
Again, this is really going to boil down to your practices. Everyone is different here ,and we actually had a Thrive session on just this topic. Typical trend in the community is to ask for half up front and the second half after completion.
How can I protect myself from clients that don’t pay?
That’s a good question - and this is EXACTLY what we talked about during the Thrive session. You can watch it here: https://www.youtube.com/watch?v=ojQeYOzq8zc&t=5s
