Client Engagement Closeout Checklist

The engagement manager pulls the WIP report from Karbon, TaxDome, or your practice-management tool and confirms every staff timesheet through the closeout date is approved. Unposted time after closeout is the most common reason realization rates are misstated.

For fixed-fee engagements, compare actual hours × standard rate to the agreed fee — flag scope creep over 15% for a change-order discussion. For T&M, confirm every billable hour ties to the engagement letter scope and rate card.

Generate the final invoice in QuickBooks, Xero, or Practice Ignition. Apply any retainer balance, post the receivable, and confirm the prior aging is cleared. Do not move to archival until the final invoice is sent — recovering fees after archival is a known revenue leak.

Compare actual hours vs. the engagement-letter budget. If actual exceeds budgeted hours by more than 15%, flag for a change-order conversation before closing out — absorbing scope creep silently destroys realization across the firm.

Draft a supplemental invoice referencing the original engagement letter and the out-of-scope work performed. Get partner approval before sending; route through Practice Ignition or DocuSign for client acknowledgement.

Pull the engagement file from Caseware, CCH ProSystem fx Engagement, or your DMS. Confirm lead schedules tie to the trial balance, every workpaper is signed off by preparer and reviewer, and review notes are cleared. AICPA quality-management standards require this before partner sign-off.

Move the PBC items, engagement letter, signed representation letter, and final deliverables into the client folder. Apply the firm's retention tags so the documents are not purged early.

IRS Circular 230 and AICPA Ethics Interpretation 1.400.200 require preparers to retain workpapers for seven years (some states longer — CA is seven, NY is six on attest). Lock the engagement folder against edits and confirm the retention timer started.

For attest clients, log the AICPA independence questionnaire result in the permanent file. Note any nonattest services performed during the year — bookkeeping for a review-engagement client is the most common breach and surfaces in peer review.

Send the signed report (audit opinion, review report, compilation report, or tax return acknowledgement) along with the management letter through Liscio, TaxDome, or the firm's secure portal. Email attachments with PII are a WISP violation under IRS Pub 4557.

Walk the client through the deliverable, the management letter findings, and any open items. Cover next-year planning while the engagement is fresh — this is also the moment to spot recurring-work opportunities.

Use DocuSign or the portal's e-signature to capture client acknowledgement that the deliverables were received and accepted. This document closes the loop on the engagement letter scope.

Work the open-item list with the client's controller until each item is resolved or formally deferred to next year's engagement letter. Do not archive the engagement with unresolved items — they reappear at peer review.

Update the engagement status, set the closeout date, and stop any recurring task automations. Open tasks tied to a closed engagement clutter the firm's work-in-progress dashboard and skew capacity reporting.

Revoke access for any contractors, valuation specialists, or outside counsel who had read access to the engagement folder. Stale portal accounts are a Safeguards Rule finding waiting to happen.

Log the engagement outcome, realization, and any cross-sell opportunities surfaced during the close meeting (R&D credit study, ERC review, fractional CFO, advisory). Tag the renewal date so proposal work starts 60 days out.

The senior manager facilitates a 45-minute review with the engagement team. Cover budget vs. actual hours, review-note volume, recurring client friction, and what to bake into next year's PBC list. Capture lessons in the firm's knowledge base.

Each reviewer submits written feedback on staff and senior performance into the firm's HR system. Tie observations to specific workpapers or review notes — generic feedback is unactionable at year-end review time.

Notify the resource manager so staff can be reassigned. For fixed-fee engagements that ran over budget, flag the staff impact so capacity planning for next year reflects actuals, not the original estimate.

For first-time engagements (new industry, new framework, new attest type), staff often qualify for CPE under the AICPA's nano-learning and on-the-job criteria. Confirm the documentation makes it into each licensee's CPE tracker before it is forgotten.
