Property / PropTech / Web Development / Sydney
A Sydney real estate group (managing 4,200 rental properties across Sydney — 35 property managers, 18,000 tenants, AUD 1.2B in managed property value, operating across Sydney metropolitan area from Parramatta to Bondi to North Shore) needed a custom web platform replacing multiple disconnected systems. (1) Systems: property management across 5 disconnected systems — legacy property management software (PropertyMe), separate maintenance request system (email-based), accounting (MYOB), document management (SharePoint), and communication (email and phone). Manual: property managers spending 3+ hours daily on administrative tasks — re-entering data between systems, manually tracking maintenance, and managing communication through email. Errors: data inconsistency across systems — tenant contact details different in PropertyMe versus MYOB, maintenance history incomplete because email-based tracking losing records. (2) Tenant: tenant experience behind market expectations — no self-service portal. Maintenance: maintenance requests via phone or email — tenant calling property manager, leaving message, manager creating ticket manually, no status visibility for tenant. Payments: rent payment through direct debit only — no alternative payment methods, no real-time payment visibility. Documents: lease documents, inspection reports, and correspondence mailed or emailed — no central document repository accessible to tenants. Communication: communication gaps — tenants unable to reach property managers after hours, urgent maintenance (burst pipe, broken lock) requiring phone tag. (3) Owner: property owner reporting manual and delayed. Statements: monthly owner statements generated manually in MYOB — property managers spending 2 days per month preparing 850 individual owner statements. Reporting: owner wanting real-time visibility into property performance — rental income, expenses, vacancy, and maintenance costs. Tax: end-of-financial-year (EOFY) reporting — manual compilation of income, expenses, and depreciation schedules for each property. Compliance: Residential Tenancies Act (NSW) compliance — bond lodgement, inspection schedules, and notice periods tracked manually with risk of non-compliance. (4) Maintenance: maintenance management being the biggest operational pain point. Tracking: no centralised maintenance tracking — requests in email, phone notes, and spreadsheets. Contractors: 85 preferred contractors with no systematic management — availability, pricing, and performance not tracked. Allocation: maintenance allocation manual — property manager deciding which contractor to send based on personal knowledge. Cost: maintenance cost tracking poor — invoices processed through MYOB but not linked to specific maintenance requests or properties. History: no maintenance history per property — when tenant reports recurring issue, no easy way to see previous repairs. (5) Growth: group wanting to grow from 4,200 to 8,000 properties within 3 years — current systems unable to scale. Hiring: scaling requiring proportional staff increase — current ratio of 1 property manager per 120 properties unsustainable for growth. Competitive: competitors (Ray White, LJ Hooker, Belle Property) investing in technology — falling behind in tenant and owner experience.
We built a comprehensive property management web platform over 12 weeks — Next.js frontend, Node.js API, PostgreSQL database, deployed on AWS Sydney. (1) Unified platform: single source of truth. Architecture: single web application replacing 5 disconnected systems — property management, maintenance, accounting integration, document management, and communication unified. Database: PostgreSQL database — all property, tenant, owner, contractor, and financial data in single database with proper relational model. API: RESTful API — enabling web portal (primary), future mobile app, and third-party integrations. Real-time: WebSocket connections — real-time updates for maintenance status, messages, and notifications. Migration: data migration from PropertyMe, MYOB, and SharePoint — 4,200 properties, 18,000 tenant records, and 5 years of financial history migrated with full validation. (2) Tenant portal: self-service for 18,000 tenants. Dashboard: tenant dashboard — lease summary, upcoming inspections, payment history, and active maintenance requests. Maintenance: online maintenance requests — tenants submitting maintenance requests with photo upload, urgency selection, and preferred access times. Tracking: real-time maintenance tracking — tenant seeing request status (received, allocated, scheduled, in progress, completed) with notifications at each stage. Payment: rent payment options — direct debit (existing), PayTo (real-time payment confirmation), BPAY, and credit card. Documents: document centre — lease agreements, inspection reports, correspondence, and receipts accessible anytime. Communication: in-app messaging — direct communication with property manager through platform, with message history preserved. After-hours: after-hours maintenance — urgent maintenance requests flagged and auto-assigned to emergency contractor with tenant notification. (3) Owner portal: real-time property performance. Dashboard: owner dashboard — portfolio overview showing all properties, current tenants, rental income, and vacancy status. Financial: real-time financial reporting — income, expenses, and net return per property and portfolio-wide. Statement: automated monthly statements — generated automatically from platform data, no manual compilation. Tax: EOFY tax package — automated compilation of rental income, expenses, depreciation, and capital works deductions formatted for tax agent. Maintenance: maintenance transparency — owners seeing all maintenance requests, costs, and photos for their properties. Market: market insights — rental price benchmarking against comparable properties in the area (data from domain.com.au API). (4) Property manager tools: operational efficiency. Workflow: workflow automation — routine tasks (inspection scheduling, lease renewal, rent review) automated with reminders. Compliance: NSW compliance automation — Residential Tenancies Act compliance built into workflows (bond lodgement with NSW Fair Trading, inspection notice periods, termination notice requirements). Inspection: digital inspection reports — tablet-friendly inspection form with photo capture, condition assessment, and tenant sign-off. Lease: digital lease management — lease creation from templates, electronic signatures (DocuSign), and automated renewal workflow. Arrears: arrears management — automated arrears detection, graduated response workflow (SMS reminder → email → formal notice → NCAT preparation), and reporting. Dashboard: management dashboard — portfolio performance, team workload, compliance status, and financial overview. (5) Maintenance system: end-to-end maintenance management. Triage: intelligent triage — maintenance requests categorised by urgency (emergency, urgent, routine) and trade (plumber, electrician, locksmith, general). Auto-assign: auto-assignment — routine maintenance auto-assigned to preferred contractor based on trade, location, availability, and past performance rating. Contractor: contractor portal — contractors receiving jobs, submitting quotes, scheduling appointments, and uploading completion photos through web interface. Approval: cost approval workflow — maintenance under AUD 500 auto-approved, AUD 500-2000 requires property manager approval, above AUD 2000 requires owner approval. Invoice: invoice management — contractor invoices matched to maintenance requests, approved through platform, and synced to Xero (migrated from MYOB) for payment. History: complete maintenance history per property — every request, repair, cost, and photo preserved for property lifecycle.
Results over 12 months. Efficiency: property manager administrative time reduced from 3+ hours daily to 45 minutes — automated workflows and unified system eliminating re-entry and manual tracking.

Portal: 82% of maintenance requests now submitted through portal (previously 100% phone/email) — reducing property manager phone time significantly. Payment: on-time rent payment improved from 88% to 95% — PayTo enabling real-time payment confirmation, automated reminders reducing late payments. Arrears: arrears balance reduced 40% — automated arrears workflow catching late payments earlier and escalating consistently.

Contractor: contractor response time improved 35% — digital job allocation and contractor portal replacing phone calls. Growth: property portfolio grew from 4,200 to 5,800 properties in 12 months — technology enabling growth without proportional staffing. Revenue: management fee revenue from AUD 8.4M to AUD 11.6M — growth enabled by platform efficiency.
