LeaseAccounting.app is the self-serve IFRS 16 and FRS 102 lease accounting platform built for SME finance teams that need audit-ready compliance without spreadsheets, implementation consultants, or six-figure software contracts. Made by ZenTreasury Oy in Helsinki, Finland with EU-only data hosting. Who it's for: group controllers, finance managers, and CFOs at companies reporting under IFRS 16, FRS 102 (UK GAAP), and ASC 842 (coming soon), typically managing 5 to 50 leases across 1 to 10 entities. Core workflow: upload your lease contracts; AI-assisted contract extraction reads each PDF and proposes around 25 fields with confidence scoring; you review and approve; the deterministic calculation engine produces the right-of-use asset, lease liability, journal entries, schedules, modifications, remeasurements, and indexation entries automatically. Same inputs, same outputs, every time. Zen AI is advisory only and never touches a calculation. Capabilities include: Discount Rate Advisor (reference rates from central bank sources, AI drafts the rate memo for review), continuous compliance monitoring (flags indexations due, expiring leases, and overdue reassessments daily), multi-entity bookkeeping from day one, one-click audit evidence packs that auditors can verify independently, and auditor portal access with activity logging (coming soon). Integrations: journal export to SAP (BKPF/BSEG), Oracle (FBDI), Microsoft Dynamics, and NetSuite formats. Azure AD / Entra ID SSO with JIT provisioning and domain verification. Live Sage Intacct API integration in development. Pricing: free tier covers 2 leases with no credit card required. Starter €149, Growth €349, Pro €699 per month, with no per-seat pricing and generous team access included on every tier. Built IFRS-first, EU-hosted, and fully self-serve. The alternative to spreadsheet chaos and consultant-heavy enterprise lease tools.

Sondu is a modular operating system created for service businesses that want bookings, communications, space management, and professional sessions managed from one connected platform. Instead of requiring a business to piece together several unrelated tools, Sondu offers four products that can work independently or share information across the same account. Schedule is designed for appointment-based businesses and provides online booking pages, deposits, email reminders, automated waiting lists, and multi-person scheduling options. Connect centralizes customer enquiries from website chat, email, Instagram DMs, and Facebook Messenger so staff can work from a single queue. Its AI assistant drafts responses based on approved information and current diary data, while keeping a human in control of every message that is sent. Reserve supports businesses that rent rooms, studios, desks, chairs, or similar spaces by providing live availability, custom rate cards, off-peak pricing, member access, and automated monthly statements. Consult focuses on professionals selling one-to-one time and includes recurring sessions, built-in video rooms, invoicing, automated balance chasing, and multilingual customer emails. Because the products use shared data, customer conversations can sit alongside booking details, deposits, histories, and space reservations instead of being scattered across separate systems. SONDU One combines Connect, Schedule Team, and Reserve for businesses that need messaging, appointment management, and space rental tools together. The company charges flat subscription fees rather than commissions and also offers free migration from existing systems, product-specific free trials, and discounts for combining products. Sondu is especially relevant for salons, clinics, therapists, consultants, coworking spaces, studios, and other service businesses that want to simplify operations while retaining control of their customers and software costs.
