Tax advisers

Connect every analysis to verifiable sources.

Eight staff search internal precedents and collect documents before preparing a brief. Versions and tax periods sometimes become mixed.

These cases show how we would apply our method to different professional situations. Business profiles, countries, timelines and gains are illustrative assumptions. They do not describe completed client engagements.

Simulated schedule
8 weeks
Support planned in the scenario
10 consulting days
Simulated net time saving
27 h / month

Assumed internal commitment : 4 person-days. Consulting days are spread across the schedule and do not mean full-time attendance. Internal days are additional. Scope and a quote must be agreed for a real engagement.

01 / Proposed audit scope

Tax advisory firm

Factual preparation of a brief within a defined tax scope, without automated regime selection or advice.

What we would examine

20 redacted briefs, sources labelled by country and period, and questions with known answers.

02 / The process, department by department

The approach to compare

Search an authorised, dated corpus with citations and abstention when sources are missing. Explicitly test period and jurisdiction confusion.

What stays with the professional

The adviser checks source currency, the client’s circumstances and every conclusion. No automated filing, final tax calculation or advice.

03 / From audit to an independent team

8 weeks.
10 consulting days.

A simulated engagement timeline, with a decision and deliverable at every stage. Rollout depends on test results.

  1. Week 1 · 2 consulting days

    Observe & measure

    20 redacted briefs, sources labelled by country and period, and questions with known answers.

    Proposed deliverable Process map, baseline measurement and issue register.

  2. Week 2 · 1 consulting days

    Scope & decide

    Compare simplification, existing features and AI. Define scope, access, full costs and stop criteria before building.

    Proposed deliverable Audit report, priority matrix and test protocol.

  3. Weeks 3–5 · 3 consulting days

    Prototype

    Search an authorised, dated corpus with citations and abstention when sources are missing. Explicitly test period and jurisdiction confusion.

    Proposed deliverable Limited prototype, test set and approval workflow.

  4. Weeks 6–7 · 2 consulting days

    Test & decide

    Every reference must be retrievable for the correct country and period; unsupported answers must be withheld.

    Proposed deliverable Comparative assessment: proceed, adjust or stop.

  5. Week 8 · 2 consulting days

    Train & hand over

    Train users on routine and exceptional cases. Appoint an owner and document the manual fallback. If testing fails, hand over findings and a correction plan.

    Proposed deliverable Usage guide, team workshop and 30-day follow-up plan.

04 / What the scenario aims to achieve

Simulated net time saving

27 h / month

Free time to analyse client-specific issues and discuss options.

Assumed monthly volume
72 brief preparations
Baseline time per unit
60 min
Target time, including human review
35 min
Monthly monitoring and maintenance
3 h

Transparent calculation

72 × (60 − 35) ÷ 60 − 3 = 27 h / month

Volume × (baseline time − target time) ÷ 60 − monthly monitoring.

If only half the volume benefits from the process, with the same monthly monitoring: 12 h / month

This calculation is a simulation, not a client measurement. Target time includes corrections and review. Time released is not a demonstrated cash saving; it depends on actual volume and adoption.

Costs to compare with the benefit

Cost advice, data preparation, integration, licences, training and maintenance before committing. Price, return on investment and revenue effects must be established for each engagement.

How we would verify the result

Compare both methods on a set separate from preparation examples. Measure total time, corrections, critical errors and actual use. Keep difficult cases in the assessment; suspend if quality or confidentiality deteriorates.

Professional acceptance criterion : Every reference must be retrievable for the correct country and period; unsupported answers must be withheld.

After the pilot

During the 30 days after an approved pilot: review metrics weekly, examine exceptions and decide whether to maintain, correct or expand the scope. This follow-up period is outside the scenario schedule and consulting days.

Before a pilot, define permitted data, access and any supplier reuse. Country-specific and professional rules must be checked for the real engagement.
