What should a representative prepare before calling the practitioner line?

Prepare the call like a short case conference.

At minimum, the representative should have:

• authorization status
• taxpayer identifying details
• tax years involved
• notice numbers and dates
• transcript highlights
• payment confirmations
• prior correspondence history
• the specific action requested

Example:

Pine Street Advisory calls about a client's balance-due notice. Before calling, the representative has the notice, transcript, proof of payment, and representative authorization ready. The representative's question is narrow: why does the payment still show as unapplied, and what account action is needed?

That is stronger than calling with a vague statement that the client is upset. Phone access is limited, so the file should be ready before the call begins.
