1. The price of the issue.
In different services, the price of a license and rent is different, but in most cases the scheme is standard: the longer the lease term, the greater the discount.
2. Ability to transfer to your own hosting.
If you are planning to build a serious online business, what is the point of limiting yourself in the future in the capabilities of the site? Why develop and fill content and pay rent for years? If the business is for the future, then only with the option of full transfer.
3. FTP access.
At the rental stage - a significant advantage - is full access to FTP, which is rare in leased sites. It will not be difficult for you to make some edits or refinements if necessary.
4. Free domain.
Many services provide a free domain with a subscription of 1 to 6 months. This is a nice bonus, agree?
5. Store management via smartphone.
Pay attention to the functionality of the admin version in the mobile application. The idea is that they should match the desktop version. But most often, with their help you can add a new product, or replace the price. If you want to avoid working on a PC 24 hours a day, and quickly manage all processes remotely, it is worth emphasizing this.
6. The work of the support service.
Two difficulties: its presence and prompt response.
Some have it, some do not. But if there is, it is important to understand how quickly the feedback is given, is it in 10 minutes, or is it the day after?
Each сonstructor for the site has its pros and cons. However, one of the main tasks of the constructor is to have access to FTP at the lease stage.
