Integrate other features into Client reports. WP MUDEV has - 1)Uptime Monitor/Report,
2)Security Updates (with Malware Scanning, Blocklist Monitor, IP Lockouts all over the period (1 month, year, etc. when they are scheduled),
3) Performance (past 1 year over year comparison), and
4) SEO Audits
using Google Lighthouse SEO. This would make for a more complete user-report to enhance the client-end experience with what they are paying for.
5) Backups - Showing when the latest backup was done (server/off-server sides)
Not sure if some of these can be added to reports via CloudFlare data, Google Page Insights, Lighthouse, etc. Or if other plugins are needed, but these would be great additions to upsell on.
