Buyer's guide
The main FRS 102 lease accounting tools for UK and Ireland SMEs are Lease102, IRIS Innervision, Leasify, FinQuery, Rubli, OneTouch Leasing and Trullion. They differ on whether the engine is FRS 102 Section 20-native or adapted from IFRS 16, whether SME pricing is published, and whether UK SONIA / OBR rates and AI lease extraction are built in.
Six criteria that separate a tool that merely supports FRS 102 from one built for it.
Some tools are IFRS 16 or ASC 842 engines with FRS 102 bolted on. A Section 20-native engine maps every input and disclosure to a FRS 102.20 paragraph, with no cross-standard reconciliation.
Enterprise lease tools are usually quote-only and priced for large portfolios. Check whether pricing is published and whether the entry tier fits a portfolio of a handful of leases.
Most SMEs use the obtainable borrowing rate (OBR). Check whether the tool helps derive it from a UK SONIA or €STR base, and whether lease data can be extracted from PDFs rather than keyed by hand.
The 2026 change is most often adopted using the modified retrospective approach. Confirm the tool calculates the transition adjustment at the date of initial application, not just steady-state periods.
The point of the software is the output. Check it produces FRS 102.20 note disclosures and journal lines that import into your ERP (Xero, Sage, Dynamics 365) rather than a generic export.
Auditors want a reconcilable input history. UK and Ireland reporters often also want UK or EU data hosting. Both are worth confirming before you commit.

Lease102 is the FRS 102 Section 20-native option positioned for UK and Ireland SMEs and their accountants. Its differentiator is the combination, in one product, of published pricing from £20 per month, a Section 20-native calculation engine, live SONIA and €STR rates for the obtainable borrowing rate, built-in AI document extraction, and UK / EU data hosting.
It is not the only tool with UK rate support: Rubli also derives the obtainable borrowing rate from a daily Bank of England SONIA-linked curve, and OneTouch Leasing is likewise UK-positioned for Section 20. The honest summary is that Lease102 leads on transparent SME pricing and an all-in-one Section 20 feature set; buyers with large or multi-standard portfolios should also look at the enterprise multi-standard tools in the table above.

There is no single best tool for every business. For UK and Ireland SMEs the practical shortlist is software that handles FRS 102 Section 20 natively, supports the obtainable borrowing rate from a UK SONIA base, automates the modified retrospective transition, and produces FRS 102.20 disclosures. Lease102, Rubli and OneTouch Leasing are UK-positioned for Section 20; IRIS Innervision, FinQuery and Trullion are multi-standard tools that also support FRS 102. The right choice depends on portfolio size, budget and whether pricing transparency matters to you.
An IFRS 16-derived tool was built for IFRS 16 (or US GAAP ASC 842) and configured to also support FRS 102. A FRS 102 Section 20-native tool was built for the UK and Ireland standard, so its inputs, discount-rate handling (the obtainable borrowing rate) and disclosures map directly to FRS 102.20 without a reconciliation layer. Both can produce compliant numbers; the difference is how much of the standard's UK-specific detail is built in versus configured.
Most enterprise lease accounting tools (IRIS Innervision, FinQuery, Trullion, Rubli) are quote-only. Among the tools compared here, Lease102 publishes SME pricing from £20 per month and Leasify publishes pricing from £225 per month. Published pricing tends to indicate a product positioned for smaller portfolios rather than large-enterprise procurement.
For most SMEs, yes. FRS 102 Section 20 lets entities discount the lease liability using the obtainable borrowing rate when the rate implicit in the lease is not available, which is the usual case. Software that derives the OBR from a daily UK SONIA (or €STR for Ireland) base plus a credit spread removes a manual, error-prone step and keeps the rate consistent across the portfolio.
Yes. Lease data (commencement date, term, payments, options) is largely standard-agnostic, so an existing lease register can usually be exported to CSV or Excel and imported into an FRS 102 tool. The discount rate and transition treatment are recalculated under FRS 102 Section 20 rather than carried over, so plan to re-derive the obtainable borrowing rate at the transition date.
Often yes. A spreadsheet can model one or two leases, but present value, right-of-use asset, depreciation, remeasurement on a rate review, and the FRS 102.20 disclosures grow complex quickly even for a small portfolio. Tools with published SME pricing (from around £20 per month) are usually cheaper than the time spent maintaining and auditing a spreadsheet.
