How We Architect Your Web Application
A modern, layered architecture that separates concerns, simplifies scaling, and makes future development faster.
Sydney Property Management — Tenant Portal
A Sydney property management company managing 800+ residential properties was handling all tenant communications via email and paper forms. Rent receipts were sent manually, maintenance requests were tracked in a shared inbox, and lease documents were stored in a shared drive with no version control.
We built a fully custom tenant portal with secure login for tenants and property managers, integrated online rent payments via Stripe (with automatic receipts to Xero), a maintenance request system with status tracking and contractor dispatch, and a document management module for leases, inspection reports and condition reports. The property management team reduced inbound calls by 55% in the first three months.
