PwC
enterprise_vendorDelivers lease accounting advisory for ASC 842 and IFRS 16, including accounting policy decisions, data capture for contracts, and readiness for audit and reporting.
Audit-ready lease accounting workpapers that preserve assumptions, calculations, and approval evidence by lease.
Teams that already have a lease inventory and transaction trail often use PwC to convert structured inputs into audit-ready accounting outcomes under strict reporting requirements. PwC engagements commonly cover policy interpretation, lease identification and classification support, measurement workflows, and standardized workpapers that link assumptions to accounting entries. This works best when internal stakeholders need clear audit trails for judgments like discount rate selection and variable payment treatment.
A tradeoff is that high-control delivery can add coordination overhead between lease, finance operations, tax, and systems owners. This fits situations where throughput is constrained by month-end timelines and where changes require controlled reprocessing rather than ad hoc spreadsheet updates. It also fits teams that need governance controls like role-based access, review checkpoints, and evidence retention aligned to internal audit expectations.
- +Strong audit trail that ties lease data, assumptions, and accounting outputs to workpapers
- +Structured delivery that supports ASC 842 and IFRS 16 interpretation and documentation needs
- +Governance-heavy engagement patterns that align with RBAC, review checkpoints, and audit log expectations
- –Requires close involvement from finance ops and system owners to maintain data lineage
- –Integration breadth can lag teams expecting fully self-serve configuration and rapid automation-only execution
Global finance operations teams

How to Choose the Right Lease Accounting Services
This buyer's guide covers how to evaluate Lease Accounting Services providers for ASC 842 and IFRS 16 delivery, with practical focus on integration depth, data model design, automation and API surface, admin and governance controls. Coverage includes Deloitte, PwC, KPMG, EY, BDO, Grant Thornton, RSM, Crowe, Protiviti, and RCFA.
The sections below translate each provider's delivery strengths into selection criteria and concrete checks. Each provider is referenced by name where it meaningfully affects contract-to-ledger mapping, audit evidence traceability, and controlled close workflows.
Lease accounting service delivery that maps contract terms into audit-grade financial reporting
Lease Accounting Services turn lease contract populations into recognition, measurement, and disclosure outputs aligned to ASC 842 or IFRS 16 requirements. Providers typically connect contract inputs to a controlled lease accounting data model, then produce audit-ready workpapers, journal outputs, and reporting schedules with defined review gates.
Deloitte and PwC often fit teams that need lease data mappings and governance artifacts tied to finance close procedures. KPMG and RSM often fit teams that prioritize governed automation workflows and audit logs across lease events, remeasurements, and modifications.
Evaluation criteria for integration depth, lease data model control, and governed automation
Lease accounting delivery breaks down when contract fields do not map cleanly to a lease data model or when approvals and audit evidence lack traceability. This is why integration depth and data model governance matter alongside automation throughput and admin controls.
The strongest providers make contract-to-period logic measurable through configuration controls, audit log expectations, and RBAC-aligned provisioning workflows. Deloitte, KPMG, and RSM are referenced here because their delivery strengths explicitly connect lease inputs to auditable outputs and governed change handling.
Lease data model mapping from contract terms to auditable outputs
Deloitte excels when lease accounting process design maps contract terms into an auditable data model that downstream reporting can trace. KPMG and EY also emphasize controlled lease-to-ledger mappings that preserve assumptions at contract and period granularity.
Audit evidence traceability for assumptions, calculations, and approvals
PwC is strongest for audit-ready workpapers that preserve assumptions, calculations, and approval evidence by lease. BDO and Protiviti reinforce the same need through auditable schedules, reconciliation workflows, and documented close governance with change tracking.
Governed configuration workflows with audit logs and RBAC alignment
KPMG and RSM lead with controlled configuration workflows that use RBAC and audit logs to segregate duties around recognition, measurement, and disclosures. EY also embeds governance with review gates and change tracking that supports audit-log style documentation.
Automation workflows that support remeasurements and modifications at scale
KPMG supports repeatable automation workflows for remeasurements and modifications using defined schemas and configuration controls. Crowe focuses on automation-oriented workflows that reduce recurring recalculation by mapping lease schedules into a controlled accounting data model across periods.
Integration depth across contract inputs, ERP and subledger sources, and reporting handoffs
Deloitte fits when integration depth requires documented process design and configuration guidance tied to the chosen accounting stack and reporting workflow. RSM, BDO, and Protiviti emphasize integration across extraction, mapping, and close workflows that keep downstream reporting continuity intact.
Admin and governance controls for change handling and close throughput
RSM is explicitly aligned to governed RBAC plus audit logging across lease data changes, approvals, and close workflow runs. Deloitte, PwC, and Protiviti also emphasize admin and governance controls tied to defined roles, review checkpoints, and traceable change tracking during close.
A decision framework for selecting the right Lease Accounting Services provider by control depth and integration fit
A practical selection process starts with how contract fields become accounting outputs. The process then validates whether governance controls can produce audit-grade traceability for assumptions and approvals.
The framework below uses integration depth, lease data model clarity, automation and API surface realities, and admin and governance controls as the decision gates. Deloitte, PwC, and KPMG are repeatedly referenced because their delivery strengths map directly to these gates.
Map contract-to-ledger logic to a controlled lease accounting data model
Demand a concrete mapping plan that shows how lease terms, assumptions, and events land in a governed data model used for recognition, measurement, and disclosures. Deloitte’s lease accounting process design that maps contract terms into an auditable data model is a strong reference point for this check, and KPMG’s governance-first data model coverage provides another benchmark.
Verify audit-grade traceability across assumptions, calculations, and approvals
Require evidence that each lease has traceable assumptions, calculation logic, and approval evidence carried into workpapers or schedules used during close. PwC’s audit-ready workpapers for assumptions and approvals by lease and BDO’s auditable lease schedules plus reconciliation workflows are direct examples to request.
Assess automation approach and the actual automation or API surface for ingestion and workflow runs
Confirm whether automation is configuration-driven inside the chosen accounting stack or delivered through an exposed automation or API surface for lease ingestion and workflow execution. EY and Grant Thornton do not present a productized API surface, so integration scope drives automation outcomes, while KPMG and RSM describe controlled automation workflows tied to schema and workflow controls.
Stress test admin and governance controls for RBAC, audit logs, and change management
Evaluate whether roles, permissions boundaries, and audit logs cover lease inception, modification, termination, and remeasurement events. RSM’s governed RBAC and audit logging across lease calculation changes and approvals is a concrete reference, and KPMG’s audit log coverage and controlled provisioning support segregation of duties.
Validate integration depth against real source systems and close workflows
Choose providers that can connect lease data extraction, mapping, and close procedures across the upstream contract systems and downstream reporting needs. Deloitte and PwC emphasize integration tied to ERP and close processes, while Protiviti and BDO focus on extracting and provisioning lease schedules into reporting and downstream control workflows.
Plan governance around throughput for recurring close cycles
Require a close-run governance approach that includes review steps, change tracking, and controlled configuration updates that can handle recurring periods. Protiviti’s documented review and change tracking aligned to finance close governance and Crowe’s structured configuration for reporting outputs across periods are specific patterns to model.
Lease accounting service buyers by governance needs and integration scope
Lease Accounting Services fit organizations that must convert lease contract populations into audit-ready reporting outputs with controlled assumptions and evidence trails. The selection depends on whether the main bottleneck is data model mapping, governed automation, or integration depth across enterprise systems.

Crowe fits when lease data provisioning and governance controls must support audit-ready outputs across reporting cycles with structured configuration.
Common selection pitfalls that break lease accounting audit evidence and automation throughput
Lease accounting failures during implementation usually come from mismatched data model assumptions, incomplete governance coverage for audit evidence, or overestimating automation and API readiness. These pitfalls show up across multiple providers based on their stated cons and delivery patterns.
The fixes below name providers that keep governance and mapping aligned so contract-to-ledger outputs remain traceable during close.
Assuming automation-only delivery without validating lease data model mapping scope
Deloitte and PwC both note that integration depth or mapping scope can require significant client-side work to avoid rework, so mapping details must be scoped early. KPMG reduces this risk through governance-first lease data model work that links contract inputs to recognition and disclosure outputs.
Neglecting audit traceability between lease assumptions and journal or disclosure outputs
Grant Thornton and EY emphasize governance and review gates but do not present a productized self-serve API surface, so traceability must be designed into the workflow and artifacts. PwC is a strong corrective example because audit-ready workpapers preserve assumptions, calculations, and approval evidence by lease.
Overlooking RBAC and audit log coverage for lease event-driven changes
RSM explicitly supports RBAC plus audit logging across lease calculation changes, approvals, and close workflow runs, which prevents gaps when modifications or terminations occur. KPMG also supports audit log coverage and controlled configuration workflows tied to model changes, which reduces evidence breakage.
Choosing a provider based on integration claims without confirming how close throughput is governed
Crowe and Protiviti both focus on structured outputs and close governance, so recurring throughput depends on provisioning design and controlled configuration updates. Providers like Protiviti add documented review and change tracking aligned to finance close governance, which is the corrective pattern to require.
Expecting a self-serve API surface when the provider emphasizes engagement-driven integration
EY, Grant Thornton, and Protiviti do not present a self-serve developer API surface in the delivery descriptions, so automation depends on engagement scope and system integration work. KPMG and RSM provide stronger governed automation workflow patterns using schemas and controlled configuration, which helps teams plan automation around workflow runs rather than missing endpoints.
