The pricing of the project can differ in several orders of magnitude. One company will price a smaller web application for 25,000 CZK and the other company for 2.5 million CZK.
The difference is in a lot of things, but in general it can be summarized by this ... "long-term sustainable quality".
The answers to these questions will determine how good a solution you need.
If you are small business, who sells 3 pieces of goods per month and you only have it as extra income, an e-shop for 10,000 CZK is enough for you.
If you are company like Alza.cz a.s. and your business is just about e-shop, then you need an e-shop for 50 million.
So if Alza.cz a.s. bought an e-shop for 10,000 CZK, it would go bankrupt. And also if a small business bought an e-shop for 50 million CZK , it would also go bankrupt.
We always try to value the project that way, how it makes sense from our point of view technologically, sustainably into the future and financially.
