The problem

What teams deal with today.

Engagement workflows in five tools

Audit in one tracker, tax in another, advisory in spreadsheets, bookkeeping in QuickBooks. Each with its own deadlines, templates, and reviewer chain. Switching cost is hours per week.

Client data chase by email

PBC schedules, bank confirmations, accruals working papers arrive via email, WhatsApp, and shared drives at unpredictable times. Half the engagement is just chasing.

Quality control gaps

Review notes in Word comments, sign-offs in email approvals, final versions on network drives. No unified record of who reviewed what, when, with what conclusion.

Junior leverage stuck on admin

Trainees spend hours filing emails, renaming attachments, chasing missing schedules. The work that would build them is what they’re not doing.

Matter types

Targeted workflows.

Each workflow is a matter template, pre-configured with trigger, stages, and outputs. Start one from the spotlight, the client portal, or a scheduled calendar event.

Statutory audit

Trigger. Engagement letter signed for the financial year. Prior-year matter carries forward trial balance and risk register.

Stages.
  1. Engagement letter and independence confirmations
  2. Planning, risk assessment, materiality
  3. Fieldwork: walkthroughs, PBC schedule, sampling
  4. Manager review, partner sign-off, EQR
  5. Report issuance and registrar filing

Outputs. Signed audit opinion, filed financial statements, working-paper file with reviewer chain, next-year matter pre-seeded with carried-forward balances.

Tax compliance

Trigger. Statutory filing calendar per jurisdiction (corporate tax, VAT/GST, payroll, withholding, transfer pricing).

Stages.
  1. Source data gathering from accounting system
  2. Computations and adjustments
  3. Internal review and signature
  4. Authority filing and payment
  5. Audit-stamped working papers and confirmations

Outputs. Filed returns, payment receipts, audit-stamped computations, refresh of next-period calendar.

Tax advisory

Trigger. Client instruction (transaction planning, residency change, restructure, controversy). Standalone or sub-matter of a larger engagement.

Stages.
  1. Scope, fact-gathering, technical analysis
  2. Options memo with trade-offs
  3. Implementation steps and required filings
  4. Sign-off, client communication, follow-up calendar

Outputs. Advisory memo, implementation step list, follow-up matters spawned for the affected filings.

Bookkeeping retainer

Trigger. Recurring engagement, monthly or quarterly cadence. Bank feed and source-document portal seeded at engagement start.

Stages.
  1. Source-document collection via portal and bank feeds
  2. Transaction coding and reconciliation
  3. Management accounts drafting
  4. Client review, sign-off, period close

Outputs. Management accounts, signed-off period close, audit-ready ledger, year-end matter pre-loaded.

Forensic review

Trigger. Suspected fraud, regulatory inquiry, dispute, or insurance claim. Chain-of-custody requirements drive the document handling.

Stages.
  1. Scope, independence, and chain-of-custody setup
  2. Document and data preservation
  3. Analysis and finding development
  4. Report drafting and partner review
  5. Final report, evidence bundle, testimony preparation

Outputs. Forensic report, chain-of-custody-stamped evidence bundle, expert witness file.

Insolvency engagement

Trigger. Court appointment, creditor application, or director instruction. Statutory deadlines drive the cadence.

Stages.
  1. Appointment formalities and creditor notification
  2. Asset realisation and creditor claim adjudication
  3. Distribution scheme and creditor approval
  4. Final accounts, discharge, court filings

Outputs. Statutory reports, distribution records, court filings, final discharge order.

Transaction support

Trigger. Buy-side or sell-side instruction. Often runs alongside the legal corporate transaction matter as a sister workstream.

Stages.
  1. Scope, data room access, request list
  2. Financial DD: quality of earnings, working capital, debt-like items
  3. Tax DD and structuring memo
  4. Findings report and reliance letter

Outputs. QofE report, tax structuring memo, signed reliance letter, working files indexed.

ESR review

Trigger. Annual statutory deadline. Substance test against jurisdictional rules per qualifying activity.

Stages.
  1. Qualifying activity identification
  2. Substance test against core income-generating activities
  3. Premises, personnel, expenditure evidencing
  4. Notification and report filing

Outputs. Filed ESR notification and report, evidenced substance file, authority acknowledgement.

Year-end accounts

Trigger. Financial year-end cadence. Prior-year accounts and TB carry forward as the opening balances.

Stages.
  1. Trial balance roll-forward and journal adjustments
  2. Statutory format drafting (per applicable framework)
  3. Director sign-off and approval
  4. Filing with registrar and tax authority

Outputs. Signed statutory accounts, registrar acknowledgement, audit-stamped working papers, next-year matter seeded.

Per file
Working papers, review notes, sign-offs, and supporting evidence on one matter record. Reviewer chain, partner sign-off, retention rule all audit-logged.
Client
Portal for PBC schedules and confirmations. Outstanding requests visible to both sides. No more “did you receive my email?”.
Reusable
Engagement templates with conditional logic. The same FY2024 audit programme spawns the FY2025 matter with carried-forward TB and variance flags.
