Compare LeaseAccounting.app vs. Solsten

LeaseAccounting.app is a self-serve IFRS 16 and FRS 102 lease accounting platform built for finance teams who want audit-ready compliance without spreadsheets, implementation consultants, or six-figure setup costs. Made by ZenTreasury Oy in Helsinki, Finland with EU-only data hosting. Designed for SMEs reporting under IFRS 16 or FRS 102 (UK GAAP), typically managing 5 to 50 leases. The platform generates complete lease schedules, journal entries, modifications, remeasurements, terminations, and one-click audit evidence packs from any lease contract. AI-assisted contract extraction reads your PDFs and proposes lease terms with confidence scoring; you approve, and the deterministic calculation engine produces the numbers. Same inputs, same outputs, every time. Zen AI is advisory only and never touches a calculation. Other features: Discount Rate Advisor pulls reference rates from central bank sources and drafts a rate memo for review; continuous compliance monitoring flags indexations due, expiring leases, and overdue reassessments; multi-entity bookkeeping from day one; auditor portal access with activity logging (coming soon); journal export to SAP, Oracle, Dynamics, and NetSuite formats; Azure AD / Entra ID SSO with JIT provisioning. Pricing: free tier covers 2 leases with no credit card required. Paid plans start at €149 per month with no per-seat pricing and generous team access included on every tier. Differentiation: built IFRS-first (not ASC 842-first), EU-hosted, fully implemented FRS 102, and self-serve onboarding. The trusted alternative to spreadsheet-based compliance and consultant-heavy enterprise lease tools.

Solsten is a cutting-edge platform that leverages AI to assist mid-market brokers, operators, and syndicators in commercial real estate underwriting, catering to those who have moved beyond Excel but find ARGUS Enterprise unnecessary. Users can create detailed financial models that include multi-property pro formas, comprehensive lease-by-lease rent rolls, varied exit strategies, and intricate investor distribution waterfalls, whether European, American, or hybrid promote, along with advanced modeling for step-up amortization and recoveries related to CAM, NNN, and multifamily RUBS. With Saga, the integrated AI assistant, support is tailored to the specifics of each user’s deal rather than relying on generic conversations. The platform ensures that every assumption is meticulously versioned, every formula is transparent and auditable, and all outputs can be exported seamlessly. While ARGUS Enterprise comes with a hefty price tag ranging from $5,000 to over $15,000 per seat annually, Solsten Professional is offered at a competitive rate of $1,932 per year, which includes access for two editor seats. Additionally, a free tier is available, allowing users to validate the platform's capabilities with one property and one analysis per month without needing a credit card. Designed specifically for independent brokers, acquisition teams, syndication sponsors, and CRE fund managers, Solsten empowers users to streamline their underwriting processes efficiently. As a result, it serves as an invaluable tool for those looking to enhance their real estate investment strategies.
