What is Lease Accounting Software? A Complete Guide for 2026

Lease accounting software is a purpose-built system that calculates, tracks, and reports the financial impact of lease obligations under current accounting standards: ASC 842 (US GAAP), IFRS 16 (international), and GASB 87/96 (government). These standards require organizations to recognize most leases on the balance sheet as right-of-use (ROU) assets and lease liabilities, a significant change from the prior rules that allowed operating leases to remain off-balance-sheet.

If your organization has leases, and nearly every organization does, the accounting treatment is no longer optional and no longer simple enough for a spreadsheet.

Why it matters

Before ASC 842 took effect, companies could keep operating leases off the balance sheet entirely. A retailer with 500 store leases would disclose the commitment in footnotes but report zero lease liability. Investors had limited visibility into the true obligation.

The new standards changed that. Every lease longer than 12 months now creates a balance sheet entry. For organizations with large lease portfolios (retail, logistics, healthcare, real estate), the impact is material. Lease liabilities of hundreds of millions of dollars appeared on balance sheets overnight when the standards took effect.

The ongoing compliance burden is substantial. Each lease requires an initial measurement (present value of future payments using an appropriate discount rate), a classification determination (operating vs. finance under ASC 842, or the single model under IFRS 16), and monthly amortization schedules for both the ROU asset and the liability. Modifications, renewals, terminations, and reassessments all require remeasurement.

Doing this in spreadsheets at scale is not just inefficient. It is a source of material misstatement risk that auditors specifically target.

How it works

Lease accounting software centralizes the lease portfolio and automates the calculations that the standards require. The workflow follows the lifecycle of each lease from inception through expiration.

Common challenges

Data extraction from contracts. Lease agreements are dense legal documents. Extracting the 15 to 20 data points needed for each lease (commencement date, base rent, escalation schedule, renewal options, termination clauses, variable payment terms) is manual, slow, and error-prone when done by hand.

Discount rate determination. ASC 842 requires the rate implicit in the lease (rarely available) or the lessee's incremental borrowing rate (IBR). Calculating IBR for each lease based on term, currency, credit profile, and collateral is a significant exercise, especially for organizations with leases across multiple jurisdictions and currencies.

Modification accounting. Lease modifications are common: rent concessions, term extensions, space reductions. Each modification requires a remeasurement of the liability and potentially a reassessment of classification. For organizations with hundreds of leases, modifications are a constant stream of recalculation.

Multi-standard reporting. Organizations that report under both US GAAP and IFRS need dual calculations for the same lease. ASC 842 maintains the operating vs. finance distinction (affecting expense pattern), while IFRS 16 treats nearly all leases as finance leases. Running both in parallel manually doubles the work.

How Arvexi handles lease accounting

Arvexi's lease accounting module covers the full lifecycle from lease abstraction through disclosure generation. AI-powered document extraction reads lease agreements and pulls the key terms automatically, reducing abstraction time from hours per lease to minutes.

Classification, initial measurement, and amortization schedules are calculated automatically based on the lease terms and your configured discount rates. When a modification occurs, the system remeasures the affected lease and adjusts the go-forward schedules without manual intervention.

For organizations reporting under multiple standards, Arvexi generates parallel calculations for ASC 842, IFRS 16, and GASB 87/96 from a single lease record. You maintain one lease portfolio and produce compliant output for each reporting framework.

The lease module is integrated directly into Arvexi's financial close platform, so lease journal entries flow automatically into the close workflow. No export, no re-entry, no reconciliation between the lease system and the GL.
