Static ecommerce for small businesses

The lockdown has highlighted the importance of having an online presence, many businesses at risk of closure have adapted and have found more or less creative solutions to continue their online business. The requests for eCommerce have increased, with the main need to have it in the shortest possible time and at an appropriate cost.
However, on the development side, there are no lean and economical solutions to build an eCommerce, for a series of factors such as the choice of the server, the choice of the CMS or the construction of an ad hoc solution, etc. Between backend development and frontend development months of work go by.
