Comparison Table
CohnReznick
specialistNational accounting firm providing audit, tax, and advisory support.
Version-controlled workpapers with disciplined review trails that keep evidence packages consistent for external auditor liaison.
CohnReznick audit support typically includes managing information requests, organizing evidence artifacts into an audit evidence index, and maintaining audit trails across drafts. Teams commonly support walkthrough documentation and control testing packages that map back to the risk and control matrix and testing outcomes. Engagement delivery also emphasizes reconciliation support across lead schedules, supporting schedules, and financial statement tie-out.
A tradeoff is that audit support quality depends on client responsiveness to the request list cadence and the ability to supply evidence in the expected formats. It fits best when finance operations already owns the general ledger detail and account reconciliation evidence and needs co-sourcing help to keep the audit evidence index and documentation current.
- +Evidence indexing and request tracking tied to audit documentation reviews
- +Experienced audit teams support control testing and walkthrough documentation packs
- +Workpaper revision history supports audit trail continuity across drafts
- +Strong reconciliation execution for trial balance to financial statement tie-out
- –Client turnaround on the request list cadence directly affects downstream evidence sufficiency
- –Automation and API surface is limited compared with software-first audit tooling
- –Evidence format expectations can create rework if source systems differ

Deloitte
enterprise_vendorBig Four professional services firm providing audit and assurance support globally.
Version-controlled workpaper production with standardized review gates that maintain audit-trail consistency across requests.
Deloitte’s audit support engagements usually center on turning client inputs into version-controlled workpapers, with structured review checkpoints for evidence sufficiency and audit trail integrity. Documentation workflows often include audit request list handling and evidence retention standards so request tracking stays consistent across stages. Teams commonly manage PBC portal workflows and evidence collection coordination for prepared-by-client deliverables and reviewer handoffs.
A practical tradeoff is that Deloitte’s documentation rigor and methodology governance can add lead time versus lighter-weight staffing firms. Deloitte fits best when the audit risk profile is high or timelines require consistent cross-functional coordination across finance teams and the audit engagement.
- +Methodology-driven documentation with consistent review checkpoints across workpaper versions
- +Strong capacity for external auditor liaison and request tracking coordination
- +Accounting and audit technical depth for complex reconciliations and testing narratives
- +Evidence handling practices that support clear traceability from source to conclusion
- –Higher governance overhead can slow evidence turnaround on short cycles

Best for: Fits when a regulated, high-risk audit needs tightly governed evidence and external-auditor coordination.
Crowe
specialistPublic accounting and consulting firm offering audit support services.
Crowe’s review checkpoints tie collected evidence to review outcomes so audit trail gaps are caught before stakeholder sign-off.
Crowe works best when audit readiness requires more than documentation gathering. The delivery model maps audit requests to accountable owners, tracks response status, and consolidates evidence into organized workpapers for review. Evidence index building and walkthrough documentation checks help reduce mismatches between trial balance detail, supporting schedules, and narrative sign-offs. The engagement handoff is structured around reviewer checkpoints that verify completeness before materials reach audit stakeholders.
A tradeoff appears when teams need deep, product-like automation such as custom APIs, automated evidence sufficiency scoring, or self-serve provisioning for audit request lists. Crowe can still manage structured workflows, but the experience depends on engagement scope and the client’s readiness to provide timely exports and approvals. Crowe fits teams that need hands-on co-sourcing during control testing preparation and financial statement tie-out rather than a tool-only workflow.
- +Structured audit-request tracking with clear owner accountability
- +Workpaper review checkpoints focus on evidence-to-balance alignment
- +External auditor liaison coordination reduces response churn
- +Version-controlled workpaper handling supports review efficiency
- –Automation depth depends on engagement scope, not self-serve tooling

How to Choose the Right audit support
Audit support services cover co-sourcing delivery of audit documentation and evidence workflows, including version-controlled workpapers, evidence indexing, and coordination for external auditor liaison. This guide compares CohnReznick, Deloitte, KPMG, and eight other major providers that support audit request list execution, review gates, and evidence packaging for submission.
The evaluation emphasis follows integration depth and automation surface where the providers deliver tooling or repeatable workflows, plus how strongly each engagement governs audit trail consistency across evidence packages. CohnReznick ranks highest for version-controlled workpapers with disciplined review trails, while Deloitte and KPMG are strong options when standardized review checkpoints must hold across requests and prepared-by-client evidence packages.
Audit support services that execute and govern evidence collection, workpapers, and auditor coordination
Audit support is the staffed and governed delivery of audit workpapers and evidence packages that connect prepared-by-client materials to reviewer sign-offs and external auditor coordination. Providers such as CohnReznick emphasize evidence indexing and request tracking tied to audit documentation review, which helps keep audit trail consistency as evidence packages move through review.
Deloitte offers methodology-driven documentation with standardized review gates across workpaper versions, which is built for regulated, high-risk audits that require tightly governed evidence handling. Across the providers covered in this guide, audit support commonly includes information request tracking, walkthrough documentation packs, and workpaper review checkpoints that enforce tie-out discipline from trial balance to supporting schedules.

Common audit support buying mistakes that break evidence governance
Misaligned governance expectations cause rework, missing evidence packages, and slow reviewer turnaround. These failures usually show up when review gate structure, request tracking cadence, or portal intake configuration is not specified before fieldwork ramps.
The most frequent issues across CohnReznick, Deloitte, and Crowe involve how evidence sufficiency depends on client turnaround cadence and how automation depth varies by engagement scope instead of being treated as a fixed capability.
Assuming automation and API-driven evidence indexing are primary deliverables for every audit support provider
CohnReznick limits automation and API surface compared with tooling-first approaches, and Grant Thornton describes automation surface as primarily operational rather than API-driven provisioning.
Overlooking the effect of client request list cadence on evidence sufficiency
CohnReznick explicitly ties downstream evidence sufficiency to client turnaround on the request list cadence, and Crowe flags that evidence export from client systems can drive setup effort.
Choosing a provider without specifying how external auditor liaison and request tracking will be coordinated
KPMG offers structured evidence workflows for consistent request list handling, while RSM US centers delivery on information request tracking coordinated for external auditor liaison across evidence owners and deadlines.
Treating portal routing as a substitute for disciplined review gates
CliftonLarsonAllen concentrates on portal-based prepared-by-client routing, while Deloitte and Crowe tie governance to standardized review checkpoints connected to workpaper versions or review outcomes.
Selecting for deliverables but not for tie-out discipline from source to supporting schedules
Grant Thornton enforces tie-out discipline from trial balance to supporting schedules, and Baker Tilly integrates reconciliation outputs into documented audit trail expectations for reviewer sign-off.
How We Selected and Ranked These Providers
We evaluated audit support providers across features, ease, and value with feature depth carrying the highest weight at 40%, then ease at 30%, and value at 30%. CohnReznick ranked highest because version-controlled workpapers are paired with disciplined review trails, and because evidence indexing and request tracking are tied to audit documentation reviews for external auditor liaison.
Deloitte and KPMG also scored strongly on governed evidence handling since Deloitte uses standardized review gates across workpaper versions and KPMG applies repeatable methodology review checkpoints tied to prepared-by-client evidence packages. Crowe ranked high for catching audit trail gaps earlier because review checkpoints tie collected evidence to review outcomes before stakeholder sign-off.
