How to charge e-commerce price

I want to know several opinion about e-commerce price. I’m web freelancer, don’t know how to charge the e-commerce pprice. Anyone can suggest to me?

You should name their own price based on competition

Look at methods of recurring income AFTER
the website is designed and delivered and
then you can work a more creative pricing
model. Recurring income is really where you
want to get to so you can build a base of
income versus a transactional business model
where you “eat what you kill”.
