Staging environment
A copy of the store where changes are tested before customers see them.
What it is
A staging environment mirrors production — same code, same data, same PHP version — so updates, plugin changes and new templates can be verified without risk to live orders.
Why it costs you money
It is what makes updates safe rather than optional. Stores that skip staging either stop updating, which is how sites get compromised, or update in production, which is how checkout breaks during a promotion.
How to check it yourself
Ask whether your host provides one, whether it clones the database on demand, and whether changes can be pushed back selectively rather than overwriting everything.
