No worries. However, there are some advantages of using the enterprise version. Many companies are selling Odoo Community, even official partners(I know at least one).

A company that I am doing project for was paying for Odoo Enterprise and actually got the Community Version. Also the "Gold Partner" have put some surprise in pg_hba config file at the end of cooperation;) . 

Regardless of version you want to offer it is worth to be a partner - you can get a leads, support, use cases and you will be able to use Odoo branding

hi there durvilchat

Hi,

There is no need to worry , you can give a demo instance for the customer and see whether he is satisfied with the existing features. 

If not tell him about the enterprise and it's features. Anyway for the community there is nothing to worry, install and configure the Odoo properly and give to your customers. Also train them how to use it. That's all. Nothing to worry, all the best.

Thanks
