Coupon website with Kentico CMS

Kentico's Documentation has guides on how to do anything in Kentico.

Kentico is a very easy platform to build sites in, and is has the tools powerful enough to accomplish any task through it's customization (such as modules, custom transformations, webparts, etc).

However, if you get into the customization realm, you should have a good knowledge of .Net, basic coding practices, and be willing to take some time to learn how Kentico is structured and how it operates.

I would shamelessly plug a recent blog article i posted which goes through how Kentico's portal method works, and maybe will give some insight to help in other areas.

To add to the great info Trevor provided, I can only add that if you're unsure of how to use Kentico or develop in Kentico, you will have a hard time. This is true with any piece of software. You should first go through some setup and different testing/scenarios before migrating anything to it. Also if you expect to map things directly to the database 1 to 1, I guarantee you, you will have nothing but problems. Accessing the database directly is not recommended and if it must be accessed directly, it is the very last resort, I don't care how good of a developer you are.

One thing you might look into is Kentico Cloud as it allows you to add content and migrate it to a Kentico site pretty easy without a lot of effort. So if your client is adding content this is the perfect place for them to do so.
