## Define the work before comparing firms.

An extension period can involve unfinished preparation and new business decisions at the same time. Ask who owns each workstream and how draft information will be distinguished from finalized records.

## Why the operating context matters.

For advertising agencies, the brief needs to explain campaign budgets, production vendors, and client billing. Explain the timing between supplier commitments and customer payment.

Use that context to request an extended-season filing and planning handoff. Identify the decision still open, the date it becomes binding, and which existing advisors are already responsible for part of the work.

## Prepare a decision-ready record list.

- Campaign ledger
- Vendor terms
- Billing schedules
- Filing calendar
- Open preparation items
- Upcoming decisions

Mark each item as available, incomplete, or held by another professional. Ask the candidate what it needs before quoting or performing analysis. A record gap should become an assigned task with a deadline, rather than an assumption that the information is complete.

## Interview the person who would do the work.

- Who reconciles campaign economics with the company’s operating reports?
- Who completes the pending returns?
- Which figures remain provisional?
- When will the planning analysis be updated?
- Which information is missing, and who will obtain it?
- What are the complete fees, exclusions, and support dates for this work?

## What a useful proposal should settle.

Request a named professional, the records reviewed, a defined output, implementation assignments, support dates, and the complete fee. Ask which work requires a separate engagement with a preparer, attorney, administrator, or specialist. Match every important deadline to a responsible person.

Compare the answer with the work you actually need. An impressive firm name or a broad service description cannot settle scope. If the proposal is unclear, record the open question and ask for clarification before engaging.
