IFRS 16 & ASC 842 lease accounting for finance teams
Stop building lease schedules in Excel.Close every month audit-ready.
If your leases live in spreadsheets, every modification means a rebuilt schedule and every audit starts with “where did this number come from?” Leash calculates every lease, posts one journal per period and keeps the trail your auditors ask for. We do the migration.

How it works
From Excel to audit-ready in one process
The same five steps every period, from the first import to the locked month-end.
- 1
Import your existing leases
We load your lease register and spreadsheets into Leash for you. No re-keying by your team.
- 2
Reconcile opening balances
We agree Leash's opening liability and right-of-use asset balances to your current ledger before go-live.
- 3
Run monthly accounting
Interest, depreciation, payments and the current / non-current split are calculated for every lease, every period.
- 4
Generate journals
One journal per company per period, mapped to your chart of accounts, with every line traceable to a lease.
- 5
Lock, report, export
Lock the period, export schedules, journals and disclosures to Excel, and hand your auditors the trail.

Built for the awkward leases
Simple leases are easy in any tool. Leash is built for the ones that break your spreadsheet.
Modifications
Changes in scope, term or consideration, remeasured from the effective date.
Escalations
Fixed-percentage escalations and custom payment schedules.
Remeasurements
Reassessments of term, options and payments, with the schedule rebuilt forward.
Terminations
Early terminations, derecognition and the resulting gain or loss.
Intercompany leases
Both sides of the lease tracked, and eliminated in the group view.
Lessor accounting
Finance and operating leases, alongside your lessee portfolio.
Exemptions
Short-term and low-value leases expensed straight-line, kept in the same register.
Custom reporting periods
Monthly, quarterly or a year-end that isn't December.
For group finance
Built for group finance
Run every subsidiary's leases in one place and get the group numbers without a consolidation spreadsheet.
- Every company in the group under one account
- Switch between a single lease, a company and the consolidated group
- Intercompany leases eliminated on consolidation
- Consolidation journals for each group reporting period
- Company and group disclosure reports, exported to Excel

Implementation
We do the migration. You check it.
Moving lease accounting is the risky part, so we don't hand you an empty system and a help centre.
- We load your existing leases from your spreadsheets or lease register
- We agree opening balances to your ledger before you go live
- We map journals to your chart of accounts and existing systems
- Your team reviews and signs off before anything is posted
You don't pay until you're happy.
No payment until you're satisfied with onboarding. Cancel at any point up to go-live, no questions asked.

Don't take our word for it
Lease numbers end up in audited financial statements. Here is why you can rely on ours.
Every number traces back
Each journal line drills down to the lease and schedule behind it, and all of it exports to Excel for your auditors.
Closed periods stay closed
Lock a reporting period once it's signed off. What you reported is what your auditors will find.
Zero take-on differences
Before go-live we agree Leash's opening balances to your ledger, so switching systems doesn't have to move your reported numbers.
