Comparison Table
KPMG
enterprise_vendorBig Four firm offering lease accounting advisory including impact assessment, process redesign, and controls.
Specialist accounting delivery that produces audit-ready documentation for complex lease term judgements across portfolios.
KPMG’s lease accounting support is built around accounting methodology work and implementation guidance that connects lease terms to measurement steps like present value and lease payment schedules. The service approach suits organizations managing many contracts with recurring reassessments, incentives, and rent abatement patterns. KPMG also supports lessor accounting and embedded lease evaluation where contract terms require judgement and documentation depth.
A key tradeoff is that KPMG’s value depends on how lease data, contract metadata, and approval workflows are prepared for intake into the engagement. Lease accounting outcomes are strongest when internal teams can provide consistent contract term definitions and change logs for modifications and reassessments. Best use cases include portfolio migrations, internal control remediation, and year-end readiness where governance and documentation matter.
- +Specialist-led judgement on renewal options, incentives, and modifications documentation
- +Methodology-to-output coverage for lessee and lessor lease accounting
- +Controlled review cycles that fit audit-focused close timelines
- +Implementation guidance for consistent portfolio term definitions
- –Relies on clean contract metadata and clear approval workflows
- –Less suited to teams seeking a self-serve tooling experience
- –Engagement deliverables may require internal ownership for operating rhythms
- –Timeline can tighten when contract exceptions are discovered late

Best for: Fits when complex lease judgements need documented control-ready delivery and specialist review support.
EY
enterprise_vendorBig Four firm delivering lease accounting transition, policy design, and ongoing compliance support.
Structured engagement governance that ties contract review, accounting assumptions, and disclosure evidence into one audit trail.
EY fits organizations that need defensible lease accounting outputs and strong audit support around assumptions, judgments, and disclosures. Delivery commonly pairs technical accounting specialists with controlled workpaper processes that trace inputs to the lease accounting results used by accounting close. The firm is also active in operational readiness, including how lease data is collected, normalized, and reconciled between legal contracts and accounting records.
A key tradeoff is that EY engagement depth increases project overhead, especially when lease data requires heavy cleansing or when scope includes unusual structures like embedded components and sale-leaseback style arrangements. EY works best when finance teams want hands-on guidance during key milestones such as lease commencement date assessments, reassessments, and lease modifications that change the accounting outcome.
- +Audit-ready workpapers that trace judgments to outputs
- +Strong handling of renewal and termination option assessments
- +Clear governance for stakeholder alignment and close integration
- +Deep technical coverage for complex lease structures
- –Higher coordination effort when lease data quality is inconsistent
- –Timeline can expand when many modifications require reassessment
- –Limited value when only basic lease schedules are needed
- –Best outcomes require finance ownership of contract input accuracy

Best for: Fits when accounting teams need defensible lease accounting judgments and strong audit support across complex portfolios.
Grant Thornton
enterprise_vendorNational accounting firm offering lease accounting advisory including gap analysis, transition, and ongoing support.
Workpaper-first delivery that ties lease term validation to calculation outputs for consistent audit trail across the portfolio.
Grant Thornton brings a practitioner approach to lease accounting standard alignment, including guidance on how to treat renewal and termination options and how to structure discount rate assumptions for present value measurement. Delivery is oriented around scoping the lease population, validating lease terms extracted from contracts, and producing an audit-ready calculation trail. The engagement pattern tends to fit organizations that want both technical review and operational buildout for ongoing lease accounting work.
A key tradeoff is that the offering is less suited to self-serve automation when there is no desire for consultancy-style data cleanup and process design. Grant Thornton works best when a leasing inventory spans many vendors, includes lease modifications and incentives, and requires consistent treatment across business units. A strong usage situation is migrating from spreadsheet-based lease accounting to controlled portfolio processing with defined review steps.
- +Hands-on technical delivery for complex lessee accounting judgments
- +Structured approach to validating lease terms from contract language
- +Audit-focused workpaper trail for portfolio calculations
- +Clear process design for modifications and remeasurement cycles
- –Consulting-heavy engagement can slow purely self-managed rollouts
- –Integration depth depends on client data availability and extraction quality
- –Large internal lease data remediation needs owner participation
- –Not ideal when teams require fully standardized plug-in automation

PwC also supports governance practices such as review checkpoints and documentation packages that help teams maintain control over discount-rate assumptions and payment schedules. For organizations with complex disclosures and multi-entity structures, PwC’s delivery focus is on policy consistency, audit-ready documentation, and repeatable processes rather than software-only outputs.
- +Strong lease accounting policy interpretation for complex lessee and lessor cases
- +Structured documentation and review checkpoints for assumptions and schedules
- +Repeatable delivery approach for lease modifications and reassessments
- +Cross-portfolio consistency support for multi-entity lease reporting
- –Less suited for teams seeking tool-first automation with minimal advisory involvement

Best for: Fits when mid-market and enterprise teams need managed implementation, controls, and audit-support for lease accounting.
Baker Tilly
enterprise_vendorNational advisory firm offering lease accounting advisory including ASC 842 assessment and process implementation.
Governance-focused lease accounting documentation and review cycles for audit-ready support across lessee and lessor reporting.
Baker Tilly serves leasing organizations needing accounting advisory and managed delivery across lease accounting workflows. Distinguishing strength comes from personnel-led support that maps lease data into compliant ledgers, including package-level reviews for lessee and lessor reporting.

End-to-end lease accounting support that ties contract term analysis to audit-ready documentation for lessee and lessor models.
EisnerAmper delivers accounting services that center on leasing transactions, including lessee accounting and lessor accounting workstreams handled by professionals rather than software automation. The firm supports recurring lease reassessments, lease modifications, and incentives through managed review of lease terms, payment patterns, and related calculations.
Engagements typically connect lease data extraction from contracts to audit-ready documentation, with deliverables designed for financial statement support and controls. For teams comparing alternatives like PwC, EY, and KPMG, EisnerAmper’s differentiator is its professional-services delivery model aimed at handling complex contract terms and documentation needs end to end.

How to Choose the Right accounting for leasing
Accounting for leasing decisions span contract term judgments, lease payment schedule outputs, and audit-ready disclosure evidence across both lessee accounting and lessor accounting. This buyer’s guide compares PwC, EY, and KPMG alongside Grant Thornton, RSM, and other delivery firms to show how leasing accounting execution differs in governance, documentation, and workflow control.
KPMG is the top-ranked service provider for complex lease term judgments with specialist-led documentation, while EY emphasizes structured engagement governance that ties contract review and accounting assumptions into one audit trail. The included providers also range from workpaper-first delivery at Grant Thornton to policy configuration and managed workflow mapping at RSM, so the evaluation should focus on how contract inputs become accounting outputs.
Accounting for leasing: converting contract terms into auditable lease accounting outputs
Accounting for leasing turns lease commencement date facts, renewal and termination options, and variable and incentive-related terms into a lease payment schedule and amortization schedule that support lease liability and right-of-use asset measurement. The work also controls reassessments and lease modifications so outputs stay aligned when discount rate assumptions and lease term judgments change.
KPMG targets specialist documentation for complex lease term judgments across portfolios, including renewal options, incentives, and modifications documentation that is designed to be control-ready. EY focuses on tying contract review, accounting assumptions, and disclosure evidence into one audit trail, which increases defensibility when renewal and termination option assessments are contentious.
Accounting for leasing services capabilities that change audit defensibility
Lease accounting execution fails most often at the seams where contract term judgments turn into lease payment schedules and audit-ready disclosure evidence for lessee and lessor models. The providers below differ most in how they control that seam, including how workpapers tie assumptions to outputs and how review governance handles renewals, termination options, and modifications.
Governance traceability from contract judgments to audit-ready workpapers
EY ties contract review, accounting assumptions, and disclosure evidence into a single audit trail. KPMG produces specialist-led judgement documentation for complex lease term decisions across portfolios.
Lease term validation workflow linked to calculation outputs
Grant Thornton delivers a workpaper-first approach that validates lease terms from contract language and ties those validations to calculation outputs. PwC aligns policy interpretation to auditable schedules with structured documentation and review checkpoints.
Policy-to-calculation alignment for both lessee and lessor cases
PwC provides structured advisory delivery that maps policy interpretation to schedules and documentation for complex lessee and lessor cases. KPMG covers methodology-to-output coverage for lessee and lessor lease accounting with specialist review support.
Lease data abstraction discipline for recurring change events
RSM maps an end-to-end workflow from lease data abstraction decisions to postings and supports later review cycles with document review discipline. Guidehouse structures lease data abstraction and reconciliation for recurring events across multi-entity portfolios.
Renewal, incentives, and modification documentation quality for judgment-heavy portfolios
KPMG provides specialist-led judgement on renewal options, incentives, and lease modifications documentation that is designed to be control-ready. EisnerAmper supports professional-led lease term review for complex renewal and termination options and tailors documentation to financial statement readiness.
Assumption and calculation trace documentation for controlled sign-off
Protiviti ties contract terms to lease schedules through assumption and calculation trace documentation that supports controlled review and sign-off. Baker Tilly focuses on governance-focused lease accounting documentation and review cycles for audit-ready support across lessee and lessor reporting.
Decision framework for choosing accounting for leasing services by workflow control
The selection hinges on where the organization expects failures to occur: in contract judgment capture, in the translation into schedules, or in governance and review timing across many lease changes. The providers vary most between specialist-led documentation delivery and consulting-led workflow execution that depends on engagement scope and client data readiness.
Choose specialist documentation delivery when lease judgments drive audit outcomes
Select KPMG when complex lease term judgments require specialist-led documentation that covers renewal options, incentives, and modifications across portfolios. Select EY when accounting teams need structured engagement governance that traces contract review, accounting assumptions, and disclosure evidence into one audit trail.
Choose workflow-first delivery when lease term validation must stay coupled to calculations
Choose Grant Thornton when lease term validation from contract language must be workpaper-first and explicitly tied to calculation outputs for audit trace control. Choose PwC when policy interpretation needs to map into auditable schedules with structured documentation and review checkpoints for assumptions and schedules.
Choose managed implementation when lease data abstraction and postings require end-to-end mapping
Choose RSM when lease accounting implementation requires end-to-end workflow mapping from lease data abstraction decisions to postings with later review cycle discipline. Choose Guidehouse when governed abstraction and reconciliation are needed for multi-entity portfolios with recurring lease accounting events.
Choose consulting-led controls when many contracts require controlled sign-off patterns
Choose Protiviti when finance teams need assumption and calculation trace documentation that supports controlled review and sign-off across change events. Choose Baker Tilly when a mid-market team needs governance-focused documentation and review cycles that support audit-ready lease judgments for both lessee and lessor reporting.
Decide based on data readiness and approval workflow discipline
If contract metadata and approval workflows are clean, KPMG’s reliance on clean contract inputs supports specialist judgement documentation without slowing governance. If lease data quality is inconsistent, EY’s coordination effort can expand timelines when modifications trigger reassessments.
Which teams should use accounting for leasing services
Accounting for leasing services fit teams with judgment-heavy portfolios or recurring lease changes that require audit-ready workpapers spanning both lessee accounting and lessor accounting. The strongest fit depends on whether the team needs specialist documentation, workflow-first validation, or consulting-led controls for many contracts.
Finance teams with complex renewal and incentive-heavy lease portfolios
KPMG supports specialist-led judgement documentation for renewal options, incentives, and modifications designed for control-ready audit support across portfolios.
Accounting teams that must defend lease assumptions in audit through traceable governance
EY ties contract review, accounting assumptions, and disclosure evidence into one audit trail and emphasizes renewal and termination option assessments.
Mid-market and enterprise teams building repeatable lease accounting processes
Grant Thornton delivers workpaper-first validation that ties lease term validation to calculation outputs and supports guided lease-accounting process build with structured audit tracing.
Organizations with high lease volumes that need managed workflow mapping from source lease inventory to postings
RSM maps lease data abstraction decisions into posting workflows and maintains document review discipline tied to lease term, renewals, and termination options.
Groups needing governed abstraction and reconciliation across multi-entity portfolios
Guidehouse supports lease data abstraction and reconciliation structured for multi-entity portfolios with recurring events that drive lease accounting execution.
Common pitfalls in leasing accounting service engagements
Leasing accounting projects break when organizations assume calculation outputs alone will satisfy audit evidence expectations. Many engagements also fail when lease data abstraction is treated as a one-time import rather than a controlled workflow that must stay aligned to contract term judgments and subsequent changes.
Treating lease data abstraction as a single import instead of a controlled process that must map to postings and later review cycles
RSM ties workflow mapping from lease data abstraction decisions to postings and uses document review discipline for later review cycles. Guidehouse structures lease data abstraction and reconciliation for recurring events across multi-entity portfolios.
Collecting renewal and termination judgments without linking them to workpapers that trace decisions to outputs
EY’s engagement governance traces contract review, accounting assumptions, and disclosure evidence into one audit trail. KPMG produces specialist-led judgement documentation that is control-ready for renewal options and modification decisions.
Scaling lease accounting execution without preparing contract metadata and approval workflow discipline
KPMG relies on clean contract metadata and clear approval workflows, so weak inputs slow the documentation workflow. Grant Thornton’s integration depth depends on client extraction quality, so unclear source-system mapping delays lease term validation.
Assuming a consulting engagement can replicate product-style automation throughput for high lease volumes
Protiviti delivery depends on engagement resourcing and cannot match product self-serve automation because the approach is constrained by consulting workflows rather than built-in lease engines. Baker Tilly’s automation and API surface are limited compared with dedicated lease software, so internal contract data ownership remains a key dependency.
How We Selected and Ranked These Providers
