There’s at least two broad options:
- Your customers buy RapidWeaver and all relevant Addons
- You create a CMS so your customers can edit key parts of the website via a web interface
My guess is a CMS approach will work better. There are a few products out there that offer CMS capabilities: Armadillo (which I use a lot), Easy CMS and Total CMS (both by a very reliable developer), and Sentry (for simpler situations). I’m sure I am forgetting some additional options. Which of these would be best for your needs is hard to know without more detail. But you’ll probably want to explore each of them.
BTW, the CMS approach will also be cheaper for your customers relative to buying RW and Addons.
