Can I update the website content later?
It depends on how much content changes and how often, and that is defined in the proposal.
Content that changes often
Menus, prices, promotions, job openings, portfolio items or posts can be edited in an admin panel, with simple forms to change text, images and items, no technical knowledge needed.
Content that rarely changes
For sites with a few pages and stable content, a panel can be an unnecessary cost. In those cases the pages are static, which makes the site faster and simpler to maintain, and occasional changes are made in the code.
As the website grows
A site that started without a panel can get one later, and specific parts can grow into a system, such as online booking or a client area.
