Excel is often the starting point for lease accounting. It’s familiar, flexible, and inexpensive, making it practical for companies managing a small number of straightforward lease agreements.
However, lease accounting becomes increasingly complicated as businesses grow. New contracts, lease modifications, payment adjustments, multiple subsidiaries, and reporting requirements under IFRS 16 or ASC 842 can quickly turn simple spreadsheets into a complex network of formulas and files.
Eventually, maintaining those spreadsheets can take more time than performing the actual accounting.
That’s when dedicated IFRS 16 accounting software becomes worth considering. Instead of managing separate calculation schedules, journal entries, and disclosure reports manually, companies can automate recurring tasks and centralize lease information.
Here are nine signs that Excel may no longer be enough for your lease accounting needs.
Can you use Excel for lease accounting?
Yes. Neither IFRS 16 nor ASC 842 requires companies to use dedicated lease accounting software.
Organizations can calculate lease liabilities, right-of-use (ROU) assets, interest expenses, and depreciation or amortization using spreadsheets, provided their accounting complies with the applicable standards.
However, maintaining accurate calculations becomes more complicated when agreements change.
Companies must account for lease modifications, remeasurements, discount rates, changing payments, and financial statement disclosures. Under ASC 842, lessees must also distinguish between operating and finance leases.
For businesses with a few straightforward agreements, Excel may be sufficient. As portfolios expand, dedicated lease accounting software becomes increasingly valuable.
9 signs Excel is no longer enough for lease accounting
1. Lease modifications require rebuilding spreadsheets
Lease agreements rarely remain unchanged throughout their entire term.
Companies extend office leases, renegotiate rental payments, terminate agreements early, or modify contract conditions.
Under IFRS 16 and ASC 842, these changes may require remeasuring lease liabilities, adjusting ROU assets, and updating accounting schedules.
In Excel, each modification can involve manually changing formulas, recalculating balances, checking payment schedules, and preparing additional journal entries.
Consider a company managing 100 property and equipment leases. If several agreements change every month, accountants may spend hours updating spreadsheets and validating calculations.
Dedicated lease accounting software automates much of this process, recalculating the accounting impact once the appropriate treatment and updated contract information have been entered.
2. Index-linked lease payments are difficult to manage
Many commercial leases include rental payments linked to inflation or reference rates.
For example, an office lease may require annual rent adjustments based on the Consumer Price Index (CPI).
Under IFRS 16, changes in payments resulting from an index or rate can trigger lease liability remeasurements, with the applicable discount-rate treatment depending on the circumstances.
With Excel, finance teams must update future payment schedules, recalculate liabilities, and prepare accounting adjustments.
The process becomes particularly complicated when different contracts have different indexation dates, currencies, and payment frequencies.
A missed adjustment can affect multiple reporting periods.
IFRS 16 accounting software simplifies this process by maintaining payment schedules and supporting the accounting adjustments required when index-linked lease payments change.
3. Lease liabilities and ROU assets are difficult to reconcile
Maintaining consistent lease liability and ROU asset balances is essential for accurate financial reporting.
However, Excel-based processes often rely on separate worksheets for liabilities, depreciation, interest, and journal entries.
If one schedule changes without corresponding updates elsewhere, balances may no longer reconcile.
For example, an accountant might correctly update the lease liability following a modification but overlook the related ROU asset adjustment.
These discrepancies can remain unnoticed until month-end or year-end reporting.
Dedicated software connects lease agreements, liabilities, ROU assets, and journal entries, helping maintain consistency across accounting records.
4. Preparing lease disclosures takes too much time
Lease accounting involves more than calculating monthly expenses.
IFRS 16 and ASC 842 require companies to prepare financial statement disclosures covering relevant lease balances, expenses, payment commitments, and other information.
When leases are managed in spreadsheets, finance teams often need to combine data from multiple files to prepare these reports.
This can involve extracting closing liabilities, preparing maturity analyses, separating lease categories, and reconciling figures against the general ledger.
As the portfolio grows, disclosure preparation becomes increasingly time-consuming.
Dedicated lease accounting software can generate standardized disclosure reports directly from lease records and accounting schedules, reducing manual consolidation work.
5. Nobody knows which spreadsheet contains the correct data
Version control is one of the biggest risks of spreadsheet-based lease accounting.
Multiple employees may maintain different versions of the same workbook. One updates payment schedules while another prepares reports using an older version.
Corrections may also be made without documenting what changed or why.
Eventually, the accounting team may struggle to identify the correct file.
While shared spreadsheets and version histories help, they don’t replace structured lease accounting controls.
Dedicated software centralizes lease information and maintains a consistent record of agreements, calculations, and modifications.
This becomes particularly important when several departments or accountants work with the same lease portfolio.
6. Auditors regularly request calculations that are difficult to explain
Auditors may request explanations of discount rates, lease terms, modifications, or changes in liability balances.
In Excel, formulas may show how an amount was calculated without explaining the assumptions or decisions behind it.
If historical versions have been overwritten, reconstructing earlier calculations can become difficult.
This creates additional work during financial audits.
Lease accounting software helps maintain structured contract records, calculation histories, and supporting documentation.
It also makes it easier to trace accounting balances back to the underlying agreements.
Although software cannot replace professional accounting judgment, it can improve the transparency and consistency of the reporting process.
7. Your company manages leases across multiple subsidiaries
Multi-entity lease accounting is considerably more complicated than managing a single company’s portfolio.
Different subsidiaries may operate in different currencies, use different accounting systems, or report under different standards.
For example, a multinational group may prepare consolidated financial statements under IFRS 16 while certain subsidiaries also require ASC 842 reporting.
With Excel, each entity may maintain separate workbooks, creating additional reconciliation and consolidation work.
Differences in formulas, assumptions, and reporting templates can introduce inconsistencies.
Lease accounting software with multi-company functionality centralizes the process while allowing finance teams to maintain entity-specific records and accounting outputs.
This makes group reporting more manageable and reduces dependence on separately maintained spreadsheets.
8. Late contract changes disrupt the monthly close
Lease information does not always reach accounting teams immediately.
A lease amendment may be signed before finance receives it. An updated payment schedule might arrive after a reporting period closes.
In Excel, correcting these situations often requires reopening previous schedules, recalculating balances, and preparing adjustments.
If multiple reporting periods are affected, the process becomes even more complicated.
Dedicated software supports structured lease modifications and accounting adjustments, making it easier to process changes while maintaining calculation histories.
The accounting team must still determine the appropriate treatment and reporting period, but software reduces the manual recalculation burden.
9. Your lease accounting depends on one Excel expert
One of the clearest warning signs is when only one employee fully understands the company’s lease accounting spreadsheets.
That person may have created the original formulas, reporting templates, and reconciliation processes.
As long as they remain available, the system appears to work.
But what happens when they leave the company or move into another role?
Other employees may struggle to maintain formulas, understand calculations, or explain historical adjustments.
This creates unnecessary operational risk.
Dedicated lease accounting software provides standardized calculations and workflows, reducing reliance on individually developed spreadsheets and making responsibilities easier to distribute across the accounting team.
Excel vs. IFRS 16 accounting software: What’s the difference?
Excel is flexible and useful for financial analysis, but dedicated IFRS 16 accounting software is designed to manage recurring lease accounting processes.
| Feature | Excel | Lease accounting software |
|---|---|---|
| Initial lease calculations | Manual formulas | Automated calculations |
| Lease modifications | Manual schedule updates | Structured recalculation workflows |
| Index-linked payments | Manual adjustments | Automated or guided remeasurements |
| ROU asset accounting | Separate or linked spreadsheets | Connected accounting schedules |
| Journal entries | Usually prepared manually | Automatically generated |
| Disclosure reporting | Manual consolidation | Standardized reports |
| Audit trails | Dependent on file controls | Structured change histories |
| Multi-company reporting | Multiple workbooks | Centralized management |
| Scalability | Increasing manual maintenance | Designed for growing portfolios |
For a small number of simple leases, the difference may be limited.
For companies managing numerous contracts, frequent modifications, or multiple entities, software can substantially reduce repetitive work.
When should you switch to IFRS 16 accounting software?
There is no universal number of lease agreements that automatically makes Excel unsuitable.
A company with 30 straightforward leases may have fewer accounting challenges than one with 10 highly complex contracts involving modifications, currencies, and variable payments.
The decision should depend on portfolio complexity, reporting requirements, and the amount of manual work involved.
Consider switching when:
- Monthly lease accounting requires substantial manual calculations.
- Lease modifications frequently disrupt reporting.
- Multiple employees maintain separate lease spreadsheets.
- Audit preparation requires reconstructing calculations.
- Financial disclosures take several days to prepare.
- Subsidiaries use inconsistent accounting models.
- Spreadsheet errors or reconciliation differences occur regularly.
If several of these problems are familiar, dedicated software is likely worth evaluating.

How to move lease accounting from Excel to software
Migrating from spreadsheets doesn’t have to mean rebuilding the entire accounting process at once.
Start by reviewing your existing lease portfolio and identifying the information needed for each agreement.
This typically includes commencement dates, lease terms, payment schedules, discount rates, renewal options, and current accounting balances.
Next, standardize the data and remove duplicate records or outdated agreements.
After importing the information into the new system, compare calculated liabilities, ROU assets, and journal entries against your existing accounting records.
Investigate differences before relying on the new reports for financial statements.
Finally, establish a consistent process for entering new contracts and approving future modifications.
A successful migration should improve not only calculation efficiency but also data quality, accountability, and financial reporting controls.
Conclusion: When Excel is no longer enough
Excel remains useful for financial modeling and small lease portfolios. However, it becomes increasingly difficult to manage when contracts change frequently, reporting requirements expand, or multiple entities depend on the same information.
The warning signs are usually clear: repetitive calculations, complicated modifications, reconciliation problems, inconsistent spreadsheets, and time-consuming audit preparation.
Switching to dedicated IFRS 16 accounting software helps organizations automate calculations, centralize lease information, maintain reporting consistency, and reduce spreadsheet dependency.
For companies looking to make that transition, SOFT4Lessee provides a practical solution for automating lease accounting while supporting long-term compliance and portfolio growth.
