Start with the operating facts

Two providers quote different cost pools for the same property.

Standardize the facts and distinguish the report from implementation.

Collect property basis; study scope; inspection approach; report deliverables; filing coordination. Match each document to the relevant entity, property and reporting period. Then choose the decision below that matches the question you need to resolve.

Unclear deliverables

Turn a broad marketing description into a written service list.

Multiple entities

Determine exactly which taxpayers and entities the quote covers.

Separate preparer

Clarify coordination when the buyer retains another return preparer.

Time-sensitive transaction

Check whether the engagement can answer the question before the decision must be made.

Incomplete source records

Determine what cleanup or reconstruction sits outside the quoted work.

Recurring costs

Compare initial and ongoing costs over the intended engagement period.

Follow-up and escalation

Define what happens after the main deliverable arrives.

Large projected benefit

Review the methodology behind a proposed financial benefit.

Changing facts

Agree how the engagement handles a material change in the business or transaction.

Evidence of implementation

Specify how the parties will know the work was actually carried out.

Credentials and roles

Verify actual engagement personnel and their responsibilities.

Cancellation and transition

Clarify records, unfinished work and obligations if the relationship ends.

Source and review boundaries

Use the following primary guidance to frame the questions. The worksheet organizes facts; it does not replace analysis of the relevant year, ownership, elections or state treatment. Record the applicable period, confirm the source version and retain the preparer's written conclusions with the supporting documents.
