Structured TP research and review

Control the work behind each TP position.

Dublon turns agreements, financial data, prior-year files and source guidance into a scoped TP dossier. It records the facts, method, evidence, review points and open items. Your team approves the position and keeps its own Local File template.

From files to control

A Local File shows the position. Dublon keeps the supporting work together.

For one material transaction, the dossier shows which facts were confirmed, which sources were used, how the method was selected and what the senior reviewer approved. Missing evidence and open questions remain visible.

01

Evidence control

Connect each material statement to a source or stated assumption.

02

Method control

Keep the selected method, tested party and rejected alternatives reviewable.

03

Cycle control

Carry approved decisions and open items into the next Local File update.

What Dublon returns for one intercompany services position.

Example scope: a Dutch service entity, a German recipient and the FY2025 Local File update. Dublon tests whether the functional profile, segmented financials and applied method tell the same story, then returns four defined review outputs.

01

Transaction and functional profile

Agreement, entities, period, functions, risks, people and value drivers.

02

Segmented financial review

Cost base, exclusions, allocation keys and results by entity and transaction.

03

Method and evidence record

Delineation, tested party, method, markup, source guidance and rejected alternatives.

04

Review and next-cycle record

Senior comments, approved position, assumptions, missing evidence and open items.

How it works

Four controls from intake to reviewed handover.

Dublon defines the question and evidence before drafting starts. Reviewers can inspect the basis for the position and the team can carry that record into the next Local File cycle.

01

Scope the TP question

Confirm the transaction, entities, period, jurisdictions and required deliverable.

02

Assemble the evidence

Collect the Local File, agreements, financial data, policies and relevant correspondence.

03

Prepare the position

Connect the facts to relevant rules and sources, then record assumptions and alternative positions.

04

Review and hand over

The senior challenges the position. The team receives the analysis, decision record, sources and open points.

Engagement model

Start with one transaction. Add support when the work repeats.

Every engagement starts with a defined transaction, review question, source set and output. Dublon confirms roles, timing, price and limitations before research begins.

FAQ

Questions TP teams ask before they start.

Do we need to replace our TP methodology?

No. Dublon starts from the methodology, chapter structure and review standards your team already uses. The engagement adds structure to the research and review record.

Can we keep our Local File and Master File templates?

Yes. Your templates remain the output format. Dublon structures the facts, sources, assumptions and review decisions that support the content.

What does the team receive?

The agreed output may be a Quick Scan, TP Position Memo or Local File input pack. It states the scope, relevant facts, assumptions, sources, alternative positions, limitations and open points.

What does AI do, and what remains with people?

AI can support extraction, source orientation, consistency checks and drafting. The responsible professional decides the material TP position, confirms assumptions and approves local nuance.

How does a scoped engagement begin?

Dublon first confirms the question, facts, desired output, exclusions and available sources. Timing, price, limitations and review responsibilities are agreed before substantive work begins.
