Lease accounting, the easy way: 5 things finance teams stop worrying about with the right setup

Lease accounting under ASC 842, IFRS 16, and FRS 102 isn’t going to get simpler on its own. But the workflow around it can - dramatically - once you stop forcing it through spreadsheets and disconnected tools.

Here are five things finance teams stop worrying about when their lease accounting setup is actually built for the job.

1. Manual journal entries

The old way: someone calculates lease entries in a spreadsheet, double-checks the math, and copies the numbers into the GL one line at a time. Every month. For every lease.

The right setup: lease journals post directly to your general ledger - interest, depreciation, remeasurements, modifications - all of it. No re-keying. No reconciliation between systems. No “wait, which version of the spreadsheet was right?”

2. Disclosure prep that takes weeks

Maturity analyses. Roll-forwards. Weighted-average rates. Cash outflow tables.

Manually? It’s a multi-day project at year-end - and a fresh one at every period close.

With the right tool, your disclosures are generated on demand, formatted to ASC 842, IFRS 16, or FRS 102, ready for your auditor. No reformatting. No last-minute scrambles.

3. Lease modifications turning into close-cycle chaos

Leases change. Contracts get extended. Payments get renegotiated. Renewal options get exercised.

Each change should trigger a remeasurement - and most spreadsheets handle it badly. Discount rate updates get missed. ROU asset and liability drift apart. Disclosure reports stop matching the underlying schedules.

The right setup recalculates the lease liability, updates the ROU asset, posts the new journals, and refreshes the disclosures - automatically. Modifications stop being a crisis. They become routine.

4. “Where did this number come from?”

Auditors ask this. Internal reviewers ask this. New hires ask this. And spreadsheets - even good ones - make it hard to answer.

A real audit trail logs every change, every calculation, every entry - with timestamps and user IDs. So when someone asks where a number came from, you can show them in 30 seconds, not 30 minutes.

That’s not just nicer to live with. It’s measurably faster audits and fewer adjustments.

5. Wondering if your team is using the full system

This one’s underrated. Most lease software is so generic, or so bolted-on, that finance teams use 20% of its features and ignore the rest. The result: the tool doesn’t pay for itself, and the workflow doesn’t really improve.

The fix isn’t bigger software - it’s software that lives where your team already works. When lease accounting is native to your finance system (in our case, Microsoft Dynamics 365 Business Central), there’s no separate login, no separate training curve, no parallel system to remember. Your team uses it because it’s already there.

How Onederful fits in

Onederful is built natively into Microsoft Dynamics 365 Business Central. ASC 842, IFRS 16, and FRS 102 - all in one platform.

That means:

• Lease journals post directly to your BC general ledger
• Disclosures generate on demand
• Modifications recalculate automatically
• Full audit trail on every change
• No middleware, no re-keying, no second system to reconcile

For finance teams, it stops feeling like lease accounting is a separate project. It just becomes part of how the books close.

The bottom line

Lease accounting will stay complex. Your workflow doesn’t have to be.
