Comparison Table
CLA
enterprise_vendorProfessional services firm providing outsourced and interim controller services for growing organizations.
Month-end close checklist and review evidence packaging that ties operational steps to audit coordination workpapers.
CLA is well suited for interim controller engagements where the main work is closing the books, validating balances, and producing consistent controller-to-CFO reporting. The engagement model typically fits teams that need hands-on oversight for account reconciliations, general ledger review, and close checklists across multiple cycles. Audit readiness work is handled through coordination deliverables that map operational steps to review evidence. For consolidation accounting or intercompany elimination support, the fit improves when the client already has defined consolidation inputs and ownership.
A key tradeoff is that CLA’s strongest contribution is in finance operations execution and control documentation, not in building new automation or API-driven systems. CLA fits well when the priority is tightening segregation of duties evidence and maintaining audit coordination while ERP migration or chart of accounts rationalization is underway.
- +Structured month-end close checklists with review evidence packaging
- +Clear controller-to-CFO reporting cadence that reduces end-of-close churn
- +Audit coordination support that aligns workpapers to review steps
- +Practical internal controls documentation for segregation of duties
- –Limited emphasis on API and automation builds
- –Best results depend on client-provided data owners and reconciliations
- –Consolidation work needs defined inputs to avoid rework loops

CFO and finance directors
Stabilize GAAP reporting package
More predictable statement prep
Creates repeatable reporting outputs and governance artifacts to support GAAP statement preparation.
Best for: Fits when interim controller needs center on close governance, audit coordination, and reliable reporting outputs.
Crowe
enterprise_vendorPublic accounting and consulting firm providing interim controller and outsourced finance services.
Control remediation planning backed by accounting advisory documentation tied to close execution evidence.
Crowe fits finance teams that need an interim controller who can own the close cadence and coordinate both internal and external audit deliverables. Typical workstreams include general ledger review, account reconciliation oversight, consolidation accounting support, and management reporting output used for controller-to-CFO updates. The engagement shape favors governance artifacts like internal controls documentation and remediation plans tied to observed process gaps.
A key tradeoff is that Crowe’s interim controller coverage is service-led rather than a self-serve automation layer, so teams seeking deep ERP-integrated automation must supply system access and workflows. Crowe works best when leadership needs rapid stabilization of close execution and external audit coordination while building a repeatable month-end checklist and control evidence package.
- +Strong audit coordination for external and internal finance stakeholders
- +Technical accounting documentation for review, escalation, and sign-off trails
- +Structured close governance with practical month-end ownership
- +Experience with consolidation accounting and intercompany elimination workflows
- –Service-led delivery means less direct process automation tooling

Best for: Fits when finance leaders need audit-coordinating interim controller coverage with governance documentation support.
EisnerAmper
enterprise_vendorAccounting and advisory firm providing interim controller and outsourced accounting services.
Control remediation tracking bundled with audit coordination deliverables for recurring close cycles.
EisnerAmper brings an integrated accounting delivery model that targets close process reliability, including month-end close checklist execution and general ledger review. The same engagement scope typically includes financial statement preparation and reporting commentary that feeds controller-to-CFO discussions with actionable variances. When consolidation accounting and intercompany eliminations become a recurring friction point, EisnerAmper can sequence those tasks inside the close workflow instead of treating them as separate deliverables.
A key tradeoff is that the engagement expects data and accounting process discipline from the finance team, since audit coordination artifacts and control documentation require timely inputs. EisnerAmper fits situations like ERP migration support and restructuring of chart of accounts rationalization, where interim controller execution must align with changing reporting structures.
- +Strong GAAP and IFRS reporting support tied to close execution
- +Consolidation work sequenced into month-end and elimination workflows
- +Control documentation produced alongside remediation tracking
- +Clear controller-to-CFO reporting cadence during transitional periods
- –Requires timely finance inputs to keep control documentation on track
- –Less suited to purely transactional AP or payroll-only coverage

How to Choose the Right interim controller
Interim controller engagements cover close governance, month-end close execution, and audit coordination deliverables that tie operational steps to review evidence and handoffs. This guide covers CLA, Crowe, EisnerAmper, BDO USA, RSM US, Baker Tilly, CBIZ, Plante Moran, Citrin Cooperman, and Aprio based on how each provider runs recurring close cycles.
The providers differ most in close checklist structure, technical accounting documentation, and how reliably deliverables connect to external audit coordination work. CLA is rated highest overall and emphasizes month-end close checklist governance and review evidence packaging that supports audit coordination, while Crowe and BDO USA lean more toward control documentation and audit-ready trails.
Interim controller services that own month-end close governance and audit-ready accounting deliverables
An interim controller provides hands-on leadership for financial statement preparation and management reporting, with close execution that typically includes general ledger review, reconciliations, and controller-to-CFO reporting cadence. Providers like CLA and RSM US organize work around month-end close checklists and GL review routines so that close outcomes have supporting review evidence.
Beyond close execution, interim controller services often include technical accounting review and audit coordination deliverables that support sign-off and documentation trails. Crowe emphasizes control remediation planning backed by accounting advisory documentation tied to close execution evidence, while EisnerAmper pairs control remediation tracking with audit coordination deliverables for recurring close cycles across entities or frameworks.
Interim controller evaluation checklist: close governance, evidence packaging, and audit coordination
Interim controller services succeed when month-end close tasks ship with review evidence that an external audit team can trace to work performed. CLA and RSM US both structure close output around checklists and GL review routines that reduce ambiguity during audit fieldwork.
Close checklist governance tied to review evidence
CLA centers delivery on month-end close checklists with review evidence packaging that connects operational steps to audit coordination workpapers. Plante Moran also produces structured month-end checklists and review trails, with more hands-on governance from the controller side.
Audit coordination deliverables with sign-off trails
RSM US organizes interim controller work around audit coordination and control documentation that tracks journal support to close outcomes. Citrin Cooperman focuses more narrowly on audit coordination with internal controls documentation that maps directly to remediation workstreams.
Control remediation planning and governance documentation
Crowe pairs control remediation planning with accounting advisory documentation tied to close execution evidence for both external and internal stakeholders. BDO USA delivers audit-ready internal controls documentation alongside controller deliverables with review notes tied to month-end close tasks.
Technical accounting documentation for complex positions
Baker Tilly combines month-end close workflow ownership with technical accounting review for complex reporting positions. Aprio staffs technical accounting alongside interim close execution to resolve revenue recognition and lease accounting issues during the monthly cycle.
Consolidation and intercompany elimination workflows for multi-entity closes
EisnerAmper sequences consolidation work into month-end and elimination workflows and ties those steps to control remediation tracking and audit coordination deliverables. CLA and RSM US emphasize close governance and GL review routines, with less emphasis on multi-entity consolidation sequencing in the card summaries.
Reviewer-led reconciliation-to-statement preparation governance
CBIZ delivers reviewer-led close and reporting workflows that tie reconciliations, statement preparation, and technical accounting memos into one governance cadence. EisnerAmper focuses on consolidation-ready month-end and elimination workflow structure, so reconciliation-to-statement governance is stronger when consolidation scope is part of the engagement.
How to choose an interim controller: delivery shape, automation expectations, and governance accountability
Interim controller engagements differ in how they translate close execution into audit-ready artifacts. Some providers package operational steps into evidence-driven workpapers, while others lead with control remediation planning or technical accounting delivery.
Pick the evidence-first delivery model when audit traceability is the gating factor
Choose CLA when the close needs month-end checklist governance plus review evidence packaging that ties operational steps to audit coordination workpapers. Choose RSM US when the priority is audit-ready documentation that tracks journal support to close outcomes across controller routines.
Pick a remediation-and-documentation-led model when controls work drives the close schedule
Choose Crowe when control remediation planning must be backed by accounting advisory documentation tied to close execution evidence and escalation and sign-off trails. Choose BDO USA when internal controls documentation for audit readiness must be delivered alongside controller deliverables with review notes tied to month-end close tasks.
Pick a multi-entity workflow model when consolidation and eliminations are in scope
Choose EisnerAmper when month-end close must include consolidation sequencing and intercompany elimination workflows that align with audit coordination deliverables. Choose other providers when the close scope is primarily single-entity governance and general ledger review, since EisnerAmper’s standout centers consolidation sequencing.
Decide whether technical accounting staffing is the primary risk reducer
Choose Baker Tilly when technical accounting review for complex reporting positions must run alongside close workflow ownership. Choose Aprio when revenue recognition and lease accounting judgments require recurring technical accounting staffed alongside interim close work.
Match client-side data access realities to the provider’s reliance on timely inputs
Choose providers like RSM US or CBIZ that are governance-heavy only if finance teams can provide timely data access and close documentation for reconciliations and review checkpoints. Choose CLA or Baker Tilly if the engagement can center on structured close delivery, since both can be constrained by client-provided reconciliations and data owners.
Set expectations for automation depth before signing a governance-heavy engagement
Choose CLA if evidence packaging is the main success metric while accepting limited emphasis on API and automation builds. Choose providers like Baker Tilly or CBIZ when automation and API surface are not the primary differentiator, since their cards describe limited tooling-first automation emphasis.
Who interim controller services fit best based on close governance and audit coordination needs
Interim controller services fit teams that need hands-on leadership to keep month-end close moving with structured review checkpoints and audit coordination deliverables. The best fit depends on whether the engagement gates on evidence packaging, control remediation documentation, or technical accounting judgments.
Finance teams stabilizing month-end close while coordinating external audit fieldwork
CLA fits teams that need close checklist governance plus review evidence packaging that ties operational steps to audit coordination workpapers. RSM US fits teams that want controlled month-end delivery paired with audit planning and fieldwork support.
Companies with control remediation backlogs that must land inside the close narrative
Crowe fits when control remediation planning must be documented with accounting advisory materials tied to close execution evidence. BDO USA fits when audit-ready internal controls documentation must be delivered alongside controller deliverables with month-end close review notes.
Multi-entity groups requiring consolidation and elimination sequencing in the monthly cycle
EisnerAmper fits when close complexity spans multiple entities or accounting frameworks and consolidation and elimination workflows must be sequenced into month-end execution. CLA and RSM US fit better when close governance and GL review routines dominate the engagement scope.
Teams facing technical accounting judgment hotspots during routine reporting
Aprio fits when revenue recognition and lease accounting issues require technical accounting staffing alongside interim close execution. Baker Tilly fits when complex reporting positions require technical accounting review paired with close workflow ownership.
Mid-market teams needing documented reconciliations and review checkpoints delivered by staff
BDO USA fits teams that need audit-coordinated interim leadership plus structured internal controls documentation supporting audit readiness reviews. CBIZ fits teams that need reviewer-led close and reporting workflows that tie reconciliations, statement preparation, and technical accounting memos into one governance cadence.
Common interim controller buyer pitfalls that derail close governance and audit coordination output
Mistakes usually show up as evidence gaps, delayed reconciliations, or mismatched expectations about what the provider will automate versus document. The cards for CLA, RSM US, and multiple audit-adjacent providers repeatedly tie outcomes to client-provided data readiness.
Selecting CLA or RSM US while underinvesting in reconciliation ownership and source data readiness
CLA’s delivery depends on client-provided data owners and reconciliations, so missing reconciliations weaken the evidence packaging. RSM US also flags governance-heavy engagements as dependent on disciplined data access and timely client inputs.
Assuming the engagement will deliver deep automation and API integration work rather than close governance and audit artifacts
CLA reports limited emphasis on API and automation builds, so integration-heavy expectations can clash with the engagement model. Baker Tilly and CBIZ similarly treat automation and API surface as not the primary delivery mechanism in the cards.
Choosing a control documentation provider when the real need is consolidation and elimination workflow sequencing
EisnerAmper is the provider carded for consolidation sequencing into month-end and elimination workflows, with audit coordination deliverables bundled for recurring cycles. Crowe and BDO USA emphasize control remediation planning and audit-ready internal controls documentation, which is not the same as consolidation workflow sequencing.
Under-scoping technical accounting judgment work when revenue recognition and lease accounting issues drive close delays
Aprio’s standout is technical accounting staffed alongside interim close work to resolve revenue recognition and lease accounting issues during the monthly cycle. Baker Tilly provides technical accounting support for complex reporting positions, but it is not positioned as the revenue and lease specialist in the card summaries.
Booking an interim engagement without providing timely close documentation needed to keep control trails on schedule
Crowe requires timely data access and close documentation from finance teams for governance documentation work to stay on track. EisnerAmper also ties control documentation timing to timely finance inputs to keep control documentation on track.
How We Selected and Ranked These Providers
We evaluated CLA, Crowe, EisnerAmper, BDO USA, RSM US, Baker Tilly, CBIZ, Plante Moran, Citrin Cooperman, and Aprio on features, ease, and value as reported in the cards. Features carry 40 percent weight because close governance and audit coordination deliverables depend on structured checklists, evidence packaging, and review trails.
Ease and value each carry 30 percent weight because several providers explicitly tie outcomes to timely client inputs and access to source systems. CLA ranked highest because month-end close checklist governance and review evidence packaging connect operational close steps to audit coordination workpapers, and the cards also describe clear controller-to-CFO reporting cadence that reduces end-of-close churn.
