in my opinion try to learn odoo is the best way, you can create your own module without paying that stuff, even if that module is not perfect you can still maintain it and fix it with yourself and your team. 

it's a good value if you determine it will work for your company.  to get many modules in a mostly complete system elsewhere costs a lot of money.

question for small biz is do you need more specific separate app providers that might focus on a particular area, or an all in one like odoo for broad coverage but maybe not in depth in a particular area.

Hi Onur,

While you're right that it has become more expensive (already for over a year though) I believe you've misunderstood the pricing model a bit. When you buy a license you have to buy the apps you need just once. So if you would want MRP (which is manufacturing and inventory) you would buy those two apps one time. This comes down to 56€ for both apps (note that pricing varies in some countries). After this you have to add the pricing per user, which is 22€ per month per user without discount. If you buy it for a year you get the users discounted at 18€ per month per user. So if you would have one user and just these two apps you would pay 74€ per month:

You can calculate the final prices in the Odoo price calculator, at https://www.odoo.com/pricing 
As for the more closed sourcing: in theory Odoo does not move community features to enterprise. A few things tend to move to enterprise in a new version but extra features are also added. For example in V12 the whole website changes and extra features are in community.
