Selling safety.
WHAT IT IS
A copy of a client's site where changes can be tested before going live.
WHY IT IS VALUABLE
It prevents the failure that costs most: a change breaking a live site.
For a client whose site generates revenue, that is worth paying for.
WHAT IT INVOLVES
A subdomain with a copy of the site and its database Protected with Directory Privacy so it is not public or indexed A process for refreshing it from live, and for pushing changes back
THE PUSH-TO-LIVE CAUTION
Pushing a staging database to a live site overwrites everything since the copy: orders, registrations, content.
Never do that on a site with live data. Push files only, or apply changes manually.
That single caution justifies the service being managed by you rather than the client.
WHO WANTS IT
Shops, membership sites, anything where downtime costs money.
Not a brochure site that changes twice a year.
PRICING
As part of a higher maintenance tier, or per site.
THE OPERATIONAL BENEFIT
You can test updates before applying them, which reduces your own risk.
