For projects requiring a constantly evolving site (adding pages, content, sections) as well as regular technical monitoring (updates, corrections, backups), a monthly support package can be offered. It can also include hosting, a domain name, or integrated services such as forms or third-party tools. Long-term support, such as SEO monitoring or the gradual integration of new features, may also justify a monthly billing method.
Rather than charging for the entire project at once, a monthly plan allows for more flexible and accessible cost allocation.

This type of billing can involve the creation of a site with a payment spread over several months, a complete offer including the site, hosting and support, or a maintenance contract to ensure the stability of the site. It can also be a service including the regular addition of new content or pages, as well as support in natural referencing or digital marketing on a monthly basis.
