Pivotal and instrumental both describe major importance. But they stress different things.
Instrumental stresses that someone or something helped cause a result. Pivotal stresses that someone, something, or a moment was central or decisive.

Learn "Pivotal" in depth →A means to the result versus central importance
Instrumental (important influence): "She was instrumental in getting the client to renew -- she personally rebuilt the relationship after the outage."
This credits her work as an important cause of the renewal. A person is common here, but a tool, event, or policy can also be instrumental.
Pivotal (central importance): "The renewal was pivotal to our Q4 numbers, even though nobody on the team did anything unusual to secure it -- the timing just happened to line up."
This describes the renewal as central to the quarterly result. It does not focus on the means used to secure it.

Where both fit
Many contexts support either word. Your choice changes the emphasis, not always the basic facts.
Ask what matters. Did it help cause the result, or was it central to the result?
"Her early warning about the vendor's delivery risk was instrumental in avoiding the outage" emphasizes what she actively did.
"Her early warning was pivotal to how the team responded" emphasizes how central that one piece of information was to the outcome, without focusing on her effort specifically.
The rule
Use instrumental in when someone or something was an important means or influence. Use pivotal to when you want to stress central importance to a result. Pivotal in is also common before an activity or process.
Neither word proves that one factor caused the result alone. In formal analysis, name the action or evidence that supports the claim.
