Automating the monthly close for lease accounting

Every month, the same cycle repeats. Recalculate amortization schedules. Generate journal entries. Reconcile the sub-ledger to the GL. Update disclosure templates. For organizations with hundreds or thousands of leases under ASC 842, this workload can consume three to five days of every close cycle.

That is three to five days the team does not have.

Automation does not mean removing the accountant from the process. It means eliminating the repetitive mechanical work so skilled professionals can focus on review, analysis, and the judgment calls that actually require their expertise.

Where time disappears in the lease close

Before looking at solutions, it helps to understand exactly where time goes during a typical close. Most teams report that the bulk of effort falls into four areas:

• Recalculating schedules. Every lease modification, payment change, or index adjustment requires updated amortization schedules. Doing this manually in spreadsheets is error-prone and slow.
• Generating journal entries. Once schedules are updated, entries must be created in the correct format for the general ledger - mapping lease accounts to GL accounts, applying entity-specific coding, handling currency conversions.
• Reconciling balances. Right-of-use asset and lease liability balances on the sub-ledger must tie to the general ledger. Discrepancies require investigation and correction before the books can close.
• Preparing disclosures. Quantitative and qualitative disclosure schedules must be updated with current-period data, often requiring manual aggregation across entities and lease types.

Each step involves transferring data between systems. Every transfer introduces latency and transcription risk. The more leases in the portfolio, the more these inefficiencies multiply.

What an automated close looks like

An automated lease close collapses these four steps into a single workflow.

The platform continuously maintains up-to-date amortization schedules as lease events occur throughout the month. When the close period arrives, journal entries are generated automatically in the format your ERP expects - complete with entity codes, account mappings, and supporting detail. No reformatting. No copy-paste. No reconciliation spreadsheets.

The capabilities that drive this:

• Event-driven recalculation. Schedules update when lease events occur, not when someone remembers to refresh them.
• One-click journal entry generation with direct ERP export or API push.
• Real-time reconciliation between the sub-ledger and GL, with variance flagging that catches issues before they become findings.
• Pre-built disclosure templates that pull from live data, eliminating manual aggregation.

Teams using automated close workflows consistently report reducing their lease close from three to five days down to a single day or less. The improvement comes not from working faster, but from eliminating the manual data movement that consumed most of the effort.

Building confidence in the numbers

The most common concern controllers raise about automation is trust. If no one manually calculated the numbers, how do you know they are right?

The answer is transparency.

A well-designed platform provides a complete audit trail for every calculation - the inputs, the formulas, the standard references behind each journal entry. Auditors can trace any balance back to its source lease agreement and verify the logic independently.

This level of traceability actually exceeds what most spreadsheet-based processes provide. In a spreadsheet, the audit trail is a set of formulas that someone built months ago and no one has documented since. In a purpose-built platform, every calculation is reproducible, every change is logged, and every output links back to its source. That is not just automation. That is a better control environment.
