Lease Accounting Services
Insero provides outsourced lease accounting services for organizations navigating ASC 842 and GASB 87 compliance, and supports software subscription accounting under GASB 96. We help middle-market businesses, nonprofit organizations, and public sector entities manage lease data, ensure accurate reporting, and maintain audit-ready documentation.
As lease portfolios grow more complex, internal teams often lack the time or specialized expertise required to maintain ongoing compliance. Insero delivers practical lease accounting solutions that improve accuracy, strengthen reporting, and reduce administrative burden.

Insero’s Approach to Lease Accounting
Practical Interpretation of Lease Accounting Standards
Insero applies ASC 842 and GASB 87 guidance within the context of operational realities, so classification, measurement, and documentation are accurate and timely.
Scalable Support Tailored to Organizational Complexity
From organizations with a handful of leases to those managing multi-entity portfolios, our support model scales to match reporting requirements and internal capacity.
Integration with Audit, Tax, and Broader Technical Accounting Needs

Insero’s integrated structure ensures lease positions align with audit expectations, tax planning, and broader technical accounting matters, reducing duplication and strengthening defensibility. We also provide post-close audit support across the portfolio, helping ensure lease accounting positions remain aligned with reporting and compliance requirements.
Partner-Level Oversight and Consistent Engagement Terms
Each engagement is overseen by experienced leaders and supported by dedicated lease accounting professionals. Clients benefit from continuity, accountability, and consistent execution across reporting periods.
