A missed break option or a late rent review notice is a significant financial event

Commercial leases have financial consequences attached to every critical date. Miss the window to exercise a break option and you're committed to another lease period. Fail to serve a rent review notice in time and you may be locked at the current rent. Overlook a service charge reconciliation deadline and your recovery right lapses.

Most commercial property teams manage these dates in spreadsheets. One person maintains the sheet. When they're on leave, nothing gets updated. When a portfolio grows through acquisition, the new leases get added to a different version of the spreadsheet. The risk isn't that the team is incompetent -- it's that a spreadsheet is not an adequate system for managing financial obligations across a portfolio of any meaningful size.

Lease management software gives every lease its own structured record, surfaces critical dates automatically before they become urgent, and generates the notices and reports your team needs without manual compilation.

What we build

Lease register and schedule management

Complete lease register covering all tenancies with lease dates, parties, demise details, current passing rent, rent-free periods, capital contributions, and lease classification. The data model supports residential, commercial, and ground lease structures, with tenant, unit, and lease term stored as linked records rather than flat rows -- so a multi-let building with thirty tenancies has one building record, thirty unit records, and thirty lease records, each independently searchable and reportable. Lease abstract extraction using AI-assisted NER (Named Entity Recognition) identifies key dates, rent amounts, break option clauses, and service charge obligations from uploaded PDF leases, pre-populating the register fields for review rather than requiring manual transcription. DocuSign or Adobe Sign e-signature integration allows new leases to be executed directly from the platform, with the signed document automatically attached to the lease record on completion. Document storage with executed leases, supplemental agreements, licences, and correspondence attached to each record. Portfolio summary showing total contracted rent, WAULT, vacancy, and upcoming expiry exposure by sector, location, or asset class. The lease register that is the source of truth for your portfolio -- not a spreadsheet that might have been updated last month and might not have been.

Critical date tracking and alerts

Automated alert system for every critical date in the lease -- rent review trigger dates, break option exercise windows, expiry and renewal notification deadlines, rent-free expiry, service charge deadlines, and any bespoke event defined in the lease. Lease expiry dashboard with rolling 90/60/30-day renewal pipeline view: all leases expiring within each window displayed with current passing rent, tenant name, and whether a renewal discussion has been initiated -- so no expiry passes without a deliberate decision to renew, re-gear, or remarket. Alert thresholds configured per event type -- first alert 12 months out, reminder at 6 months, final warning at 3 months, with additional escalation to the portfolio manager if the event remains unactioned within 30 days. Rent escalation notifications triggered automatically when a CPI review date arrives: the system calculates the new rent based on the applicable index -- CPI-U for US leases, RPI or CPI for UK -- or applies the fixed percentage increase, and generates a notification to the tenant with the new rent amount and effective date. Alerts routed to the responsible team member by property or by event type, not a single shared inbox where critical notices get buried. Dashboard showing all upcoming events within the next 90, 180, and 365 days with priority-ranked by financial exposure.

Rent review management

Rent review management covering CPI-linked reviews, fixed uplifts, open market reviews, and turnover-based rents. Rent review calendar with upcoming review dates, trigger notice deadlines, and review mechanism details. Open market review workflow where comparable evidence is recorded, negotiated position is tracked, and the agreed uplift is recorded against the lease. Upward-only and bidirectional review clauses correctly modelled. Memorandum of variation generated on completion of review. The rent review process that doesn't rely on someone's memory of which leases are due and what mechanism applies.

Break option and expiry management

Break option register with exercise window start and end dates, notice requirements, pre-conditions, and penalty rents. Break notice workflow generating the required notice document with the correct served and expiry dates, routed through approval before dispatch. Expiry management covering lease end, holding over, and renewal or re-gear. Section 25 and Section 26 notice management for England and Wales commercial leases. The break and expiry management that ensures the right notice goes to the right party within the right window without someone manually calculating dates from the lease document.

Service charge and reconciliation

CAM (Common Area Maintenance) and service charge budget and reconciliation management covering annual budget setting, on-account demand generation, year-end reconciliation, and tenant communication. Apportionment calculations based on floor area ratios or other allocation basis defined in the lease -- individual tenant's demised area as a proportion of total lettable area, or a fixed percentage where the lease specifies it. Cap and collar modelling calculates each tenant's maximum and minimum service charge liability where lease caps apply, and flags where the actual apportionment exceeds a capped amount so the recoverable shortfall is visible. Service charge audit documentation stored against the reconciliation record for each year. Reconciliation statement generated per tenant showing actual expenditure against budget, the tenant's apportioned share, the balancing charge or credit, and the supporting cost breakdown. NACHA-compliant ACH rent collection via Stripe processes both on-account service charge demands and reconciliation balancing payments, with payment status tracked in the same record as the demand. Yardi, AppFolio, MRI, and Buildium integration options allow the service charge data to sync with the accounting platform rather than requiring dual entry. The reconciliation process that recovers what you're entitled to recover without occupying your management team for six weeks every year-end.

IFRS 16 and corporate occupier reporting

For corporate occupiers managing a lease portfolio as IFRS 16 right-of-use assets (or ASC 842 under US GAAP), the system calculates right-of-use asset values, lease liability amortisation schedules, interest expense, and disclosure note data at each reporting date. The right-of-use asset calculation discounts future lease payments at the incremental borrowing rate applicable to the lease's currency and jurisdiction, producing the initial measurement figure and the subsequent depreciation schedule over the lease term. Lease modifications -- extensions, early terminations, rent amendments -- trigger a remeasurement event: the system recalculates the present value of the revised payment stream and updates both the ROU asset and the lease liability. Move-in and move-out inspection workflows capture unit condition at commencement and termination with timestamped photos, providing evidence for deposit deductions and dilapidations claims. Discount rate management stores the applicable rate per lease so historical calculations use the correct rate rather than the current rate. Monthly journal entry output -- debit ROU asset depreciation, credit accumulated depreciation, debit interest expense, credit lease liability -- formatted for import into SAP, Oracle, or any accounting system that accepts a structured journal upload. The IFRS 16 compliance process that removes the quarterly spreadsheet exercise from your finance team's workload and gives auditors a clean, traceable calculation rather than a complex model they have to reverse-engineer.

Frequently asked questions

Lease management software is a structured database of lease obligations, rights, and critical dates that surfaces upcoming events automatically and generates the notices and reports your team needs. It replaces the spreadsheet most commercial property teams use to track leases -- which works until the portfolio grows large enough that one missed update creates a significant risk event. A dedicated lease management platform is appropriate when your portfolio has enough leases that managing critical dates in a spreadsheet carries meaningful risk, when IFRS 16 compliance requires lease liability tracking across a portfolio, when the team managing the leases has multiple members and the spreadsheet is a single-person dependency, or when you're acquiring or managing a portfolio where the existing lease data needs to be systematically captured and maintained.

Commercial leases have a wide range of rent review mechanisms -- upward-only open market reviews, CPI-linked escalations with collars and caps, turnover top-ups, fixed annual uplifts, stepped rents, and hybrid mechanisms. The system models the review mechanism as defined in the lease rather than forcing every lease into a standard template. CPI escalation applies the relevant index at each review date and calculates the new rent. Open market reviews trigger the negotiation workflow at the review date. Upward-only constraints are respected in the calculations. Bespoke mechanisms -- turnover clauses, revenue sharing arrangements -- can be configured with custom calculation logic where the mechanism is unusual enough to require it.

Yes. Notice generation is one of the core functions. The system holds the notice requirements for each lease event -- notice period, form of notice, and service requirements -- and generates a draft notice document at the appropriate point in the alert calendar. The document is generated from a template that pulls the correct lease details, parties, and dates automatically. The notice then routes through an approval workflow before dispatch, so the right person reviews it before it goes out. Service is recorded against the lease record. For commercial leases where the consequences of a defective notice can be significant, the generation and approval workflow is designed to ensure nothing goes out without review.

A lease management platform covering lease register, critical date alerts, rent review management, and expiry tracking typically runs $30,000--$65,000. A more complete system with IFRS 16 reporting, service charge reconciliation, notice generation, and accounting integration typically runs $65,000--$130,000. Cost depends on the number of lease types and review mechanisms to be modelled, the IFRS 16 reporting requirements, the number of integrations, and whether document generation needs to handle multiple jurisdictions with different notice requirements.
