Crowe

enterprise_vendor

Public accounting and consulting firm providing lease accounting advisory services.

9.4/10
Overall
Features9.6/10
Ease of Use9.1/10
Value9.3/10
Standout feature

Assumption and modification governance within a maintained lease schedule workflow for ongoing portfolio changes.

Crowe’s core capability is end-to-end lease accounting execution that turns lease contract data into maintained lease schedules, journal entry support, and disclosure reporting artifacts. The service approach is oriented around governance and repeatability, including assumption setting and scenario updates for renewals, term changes, and modifications. Crowe also supports complex portfolio conditions like variable payments, incentives, and non-standard lease terms where spreadsheet-only workflows commonly break.

A key tradeoff is that Crowe is a services-led model rather than a self-serve software tool, so automation speed and system connectivity depend on how contract and payment data are provisioned. Crowe fits situations where there is already a lease inventory in spreadsheets or ERP exports and the priority is consistent accounting outputs under ASC 842 or IFRS 16. It is also a strong fit when internal lease accounting capacity is limited and review and documentation needs are high.

Pros
  • +Portfolio abstraction-to-close workflow supports consistent lease schedule maintenance
  • +Assumption governance supports renewals, term changes, and lease modifications
  • +Disclosure reporting deliverables align to period-end reporting timelines
  • +Documented review process improves audit traceability across the lease population
Cons
  • –Services-led model reduces self-serve configurability compared with pure software
  • –Data provisioning and mapping effort can be significant for messy contract sources
  • –API-driven automation is not the primary delivery mechanism

Best for: Fits when finance teams need governed, repeatable lease accounting close across many leases.

#2

Grant Thornton

enterprise_vendor

National accounting firm offering lease accounting advisory and transition services.

9.0/10
Overall
Features9.3/10
Ease of Use8.9/10
Value8.8/10
Standout feature

Managed lease accounting abstraction and reporting deliverables that translate contract terms into close-ready journal entry support and disclosure documentation.

Grant Thornton is a fit when lease accounting is tied to broader financial close workflows and when teams need help turning lease data into audit-ready outputs. Delivery commonly covers lease identification, abstraction, portfolio buildout, and support for journal entry generation logic that matches the reporting model. Engagements also emphasize documentation and governance artifacts that reduce friction during auditor walkthroughs.

A tradeoff is that the capability is service-driven instead of product-driven, so automation depth for high-volume lease operations depends on scope and engagement design. Grant Thornton works best when internal teams can provide contract data feeds and subject matter input, then collaborate on policy decisions and exceptions. It is less suitable when the priority is pure self-serve configuration without external accounting hands-on support.

Pros
  • +Structured abstraction to portfolio mapping for lease schedules
  • +Audit-focused documentation aligned to financial close deliverables
  • +Accounting judgment support for complex contract terms
  • +Process buildout that fits reporting controls and governance
Cons
  • –Service delivery means automation scope depends on engagement design
  • –Self-serve configuration depth is limited versus software-only tools
  • –Implementation timelines can be constrained by contract data readiness
  • –Governance artifacts require ongoing stakeholder participation
Use scenarios
  • Controller and close teams

    Close support for ASC 842 adoption

Best for: Fits when mid-market and enterprise teams need hands-on ASC 842 or IFRS 16 implementation support with audit documentation.

#3

Baker Tilly

enterprise_vendor

Advisory and accounting firm offering ASC 842 lease accounting services.

8.8/10
Overall
Features8.8/10
Ease of Use9.0/10
Value8.5/10
Standout feature

Controlled recalculation for lease modifications and reassessments tied to portfolio-wide assumption consistency.

Baker Tilly’s lease accounting service is oriented around end-to-end execution from data intake to lease schedule production and downstream reporting support. Teams typically address lease commencement activities, option evaluations, and consistent present value calculations needed for both operating and finance lease accounting. The delivery model emphasizes process control through engagement governance, which reduces reliance on client-owned spreadsheets for recurring portfolio changes.

A clear tradeoff is that Baker Tilly’s value comes from services delivery, so organizations seeking self-serve automation and high-throughput internal API-driven calculation typically need additional tooling. Baker Tilly fits when a mid-market or growing finance team needs faster period close for a lease portfolio with modifications and reassessments, without building a full in-house lease accounting operating model.

Pros
  • +Advisory delivery supports complex lease modifications and reassessment cycles
  • +End-to-end lease abstraction to schedule and reporting outputs
  • +Consistent assumption handling supports discount rate and option evaluations
  • +Engagement governance improves repeatability across lease portfolio activity
Cons

Lease lifecycle advisory that ties contract terms, reassessment events, and disclosure-ready assumptions into one controlled workflow.

BDO delivers lease accounting services that translate contract inputs into ASC 842 and IFRS 16 accounting workpapers, including schedules and journal entry support for lessee and lessor arrangements. Engagement teams typically handle lease abstraction, discount rate support, and policy decisions for reassessment triggers, modifications, and variable payment patterns.

The distinct value comes from BDO’s accounting advisory workflow, which aligns lease calculations to disclosure and operational controls rather than delivering only a calculation engine. BDO also supports portfolio-level governance by structuring deliverables to match review steps, sign-off, and audit traceability across the lease lifecycle.

Pros
  • +Lease abstraction and calculation workpapers built for downstream review and posting
  • +Integrated advisory handling for modifications, reassessment triggers, and options
  • +Documented review approach that improves audit traceability of assumptions

How to Choose the Right lease accounting

Lease accounting service providers in this guide cover governed lease schedule workflows, reviewer-led lease abstraction, and advisory policy-to-evidence documentation that translate contract terms into ASC 842 and IFRS 16 close deliverables. The narrative sections compare Crowe and Grant Thornton alongside EY, Deloitte, PwC, and KPMG, plus Crowe and Grant Thornton framed in the same buyer-use context for financial teams.

The provider set also includes Baker Tilly, BDO, RSM US, CohnReznick, CBIZ, Plante Moran, and Wipfli, which shape how lease modifications and lease reassessments are handled during portfolio changes and period close. This guide focuses on integration depth, automation and API surface signals where they are part of the delivery model, and administration and governance controls that govern lease schedules over time.

Lease accounting services for ASC 842 and IFRS 16 close-ready abstraction and reporting

Lease accounting is the disciplined process of converting lease contracts into lease schedules, lease liability and right-of-use asset calculations, and disclosure reporting inputs that support audit-ready review cycles under ASC 842 and IFRS 16. In practice, it includes managing discount rate assumptions, lease term definitions, variable lease payments, incentives, and the downstream journal entry generation that ties to reporting deliverables.

Crowe is built around maintained lease schedule workflows with assumption and modification governance that keeps ongoing portfolio changes controlled. Grant Thornton centers on managed lease accounting abstraction and reporting deliverables that translate contract terms into close-ready journal entry support and disclosure documentation.

Lease accounting service criteria that change outcomes in close

Lease accounting services are judged by whether they keep lease schedules consistent while the portfolio changes through renewals, amendments, and reassessments. The strongest providers turn that consistency into reviewable outputs that support journal entry generation and disclosure reporting.

  • Maintained schedule governance through modifications

    Crowe is built around maintained lease schedule workflows with assumption and modification governance for ongoing portfolio changes. Baker Tilly focuses on controlled recalculation for lease modifications and reassessments tied to portfolio-wide assumption consistency.

  • Lease abstraction to close-ready reporting outputs

    Grant Thornton provides managed lease accounting abstraction and reporting deliverables that translate contract terms into close-ready journal entry support and disclosure documentation. CBIZ produces lease schedules from abstraction outputs and ties them to ongoing accounting and disclosure deliverables for recurring updates.

  • Policy-to-evidence documentation tied to review cycles

    EY delivers a policy-to-evidence workflow that ties lease judgments and documentation directly to disclosure outputs for review cycles. Wipfli provides accounting-led execution that operationalizes lease modifications and reassessments into controlled reporting outputs.

  • Reviewer-led abstraction and portfolio consistency controls

    RSM US uses reviewer-led lease abstraction and policy application to keep lease schedules consistent during modifications and reassessments. CohnReznick standardizes lease abstraction outputs into review-ready schedules and recurring modification updates.

  • Lifecycle coverage for reassessment and assumption handling

    BDO ties contract terms, reassessment events, and disclosure-ready assumptions into one controlled lifecycle workflow. Plante Moran covers managed lease schedule and journal entry generation for period close with discount rate assumption handling to support consistent present value calculations.

Choose by workflow control model and evidence output demands

Lease accounting services differ more in delivery mechanics than in headline coverage of ASC 842 or IFRS 16. The right selection depends on whether governance is maintained inside a schedule workflow, built around reviewer abstraction, or delivered as advisory documentation that follows policy choices through to disclosures.

  • Map internal change volume to a schedule maintenance workflow

    If the lease portfolio regularly changes through renewals, term changes, and lease modifications, Crowe fits because it maintains lease schedules with assumption and modification governance. If the change pattern centers on standardized updates and recurring modification cycles, CohnReznick standardizes abstraction outputs into review-ready schedules.

  • Decide whether close readiness comes from deliverables or from review controls

    If the requirement is close-ready journal entry support and disclosure documentation produced from contract translation, Grant Thornton fits because it delivers managed abstraction and reporting deliverables. If the requirement is governance through reviewer control of lease abstraction steps, RSM US fits with reviewer-led abstraction and policy application.

  • Select the documentation posture for lease judgment evidence and review cycles

    If lease judgments must be tied to disclosure outputs for review cycles, EY fits with a policy-to-evidence workflow. If the emphasis is controlled lifecycle workpapers built for downstream review and posting, BDO fits with lease abstraction and calculation workpapers.

  • Match modification and reassessment mechanics to portfolio consistency needs

    If complex lease modifications and reassessment cycles need controlled recalculation tied to portfolio-wide assumption consistency, Baker Tilly fits with controlled recalculation tied to schedule consistency. If the requirement is consistency through recurring schedule and journal entry generation for period close, Plante Moran fits with discount rate assumption handling that supports consistent present value calculations.

  • Choose based on integration expectations and automation reliance

    If in-house automation is not the priority and a service model is acceptable, CBIZ and Wipfli deliver managed schedule building and accounting-led execution tied to deliverables. If internal data and lease inventory are already organized and speed comes from structured delivery rather than internal API build, CohnReznick aligns with its delivery model.

Who should buy lease accounting services and how each profile benefits

Teams buy lease accounting services when contract translation and schedule maintenance need repeatable governance across many leases. The best match depends on whether the organization needs schedule workflow control, reviewer-led abstraction consistency, or policy-to-evidence documentation for complex judgments.

  • Financial teams running frequent lease modifications across multi-entity portfolios

    Crowe supports portfolio changes with maintained lease schedule workflows and assumption and modification governance that reduces inconsistency during ongoing updates.

  • Mid-market and enterprise teams that need hands-on ASC 842 or IFRS 16 implementation with audit documentation

    Grant Thornton provides structured abstraction to portfolio mapping and audit-focused documentation aligned to financial close deliverables.

  • Organizations with complex lease judgment populations and disclosure review cycles

    EY ties lease judgments and documentation directly to disclosure outputs for review cycles, which supports governance during policy decision reviews.

  • Teams that prioritize controlled modification and reassessment cycles tied to assumption consistency

    Baker Tilly supports controlled recalculation for lease modifications and reassessments with portfolio-wide assumption consistency.

  • Mid-market teams that want managed lease abstraction and period close journal support without internal workflow engineering

    Plante Moran and CBIZ deliver managed schedule and journal entry generation or schedule building from abstraction outputs tied to ongoing accounting and disclosure deliverables.

Common purchase and implementation pitfalls in lease accounting

Lease accounting failures usually start with mismatched delivery mechanics rather than missing lease coverage. The category risks are concentration on self-serve configuration when services lead, reliance on client-ready source data, and unclear governance for modifications and reassessments.

  • Assuming a service-led provider will support deep self-serve configuration for lease schedules.

    Crowe reduces self-serve configurability because the model centers on governed workflows, while Grant Thornton’s automation scope depends on engagement design.

  • Underestimating data provisioning and mapping effort when contract sources are messy.

    Crowe flags that data provisioning and mapping effort can be significant, and Wipfli depends on the quality of client-provided lease documents and source system export.

  • Choosing documentation posture without matching it to disclosure review needs.

    EY is built around policy-to-evidence documentation tied to disclosure outputs, while BDO emphasizes controlled lifecycle workflows that require review-friendly workpapers for downstream posting.

  • Selecting based on period close tasks only and ignoring modifications and reassessment governance.

    Baker Tilly focuses on controlled recalculation tied to portfolio-wide assumption consistency, while RSM US emphasizes reviewer-led abstraction to keep schedules consistent during modifications and reassessments.

Baker Tilly covers lease commencement activities and option evaluations and then produces consistent present value calculations for operating and finance lease accounting. Plante Moran focuses on translating lease data into compliant accounting outputs for lessees and lessors and builds journal entry generation workflows across recurring reporting cycles.
Which provider delivery model is more suitable when finance teams want hands-on support integrated into the close process?
Grant Thornton fits when lease accounting is tied to broader financial close workflows and when auditor walkthrough friction is reduced through documentation artifacts. RSM US fits when review oversight and consistent policy application across multiple entities matter more than self-serve configuration.
How do providers structure journal entry generation and disclosure reporting outputs for review cycles?
Crowe produces journal entry support and disclosure reporting artifacts directly from the maintained lease schedule it builds. Wipfli emphasizes defined review steps and controlled outputs for recurring and event-driven lease accounting, which reduces rework during disclosure review.
When should a team choose services that standardize assumptions and governance over per-lease ad hoc spreadsheets?
CohnReznick standardizes discount rate inputs and recurring modifications and reassessments so the portfolio is updated with a consistent approach rather than handling each lease in isolation. Crowe also prioritizes assumption setting and scenario updates for renewals and term changes where repeatability and governance are required.
What data migration and system connectivity requirements typically drive onboarding effort for lease accounting services?
Crowe’s automation speed and system connectivity depend on how contract and payment data are provisioned into the lease schedule workflow. EY supports integration planning for downstream reporting and journal entry workflows with client IT and finance teams, which can shift onboarding effort from data entry to mapping and change management.
