The project

Resident services and the work behind them

Residents need a clear way to book facilities, pay fees, report a problem or arrange an apartment handover. Behind each request, property staff need the right unit details, responsible person and service status.

Twin’s programme for Sơn Kim Land covers these resident services alongside the administration and leasing work that supports them. It draws on RIO Solutions, Twin’s property software suite, which includes residential and office property management and residential Leasing CRM.

The work spans three groups with different responsibilities: residents raising requests, management staff coordinating service and leasing teams maintaining availability and agreements. Linking those tasks to property and unit records makes the operational scope visible beyond the resident app alone.

Resident experience

Everyday property services in the Highgate app

The home screen puts fees, facilities, work orders, sales and leasing, feedback, the handbook, messages and forms within reach. Fee reminders and message notifications sit alongside these services. The project selector shown in the app includes The Opera Residence, Serenity Sky Villas and The 9 Stellars.

Highgate is the property management business formerly known as Son Kim Office Company Limited. Its current resident application is Highgate Connect, published by Highgate Property Management Company Limited. The project screens shown here use the earlier Highgate Tenant branding; available functions are configured for each property.

Work orders

Follow a service request through to resolution

A resident can describe an issue, attach photos and send it to the management team. The request keeps its status, comments and assigned technician’s contact details together, so the resident can see who is handling it and what happens next.

Sales and leasing requests

Submit an apartment for sale or lease

Residents choose whether to sell or lease, then add contact details, a property description, price, floor area, bedroom and bathroom numbers, and photos. After submitting, they can check the request’s status, update the details or cancel with confirmation.

Apartment handover

Book the appointment and know who to contact

Residents select an apartment awaiting handover, choose a date and time, set a reminder and review the handover rules before confirming. The appointment record shows its status and the responsible staff member’s email and phone details. Waiting and completed handovers appear separately.

Property operations

A working view for the management office

The Property Management System supports the people handling resident requests, building records and daily operations. Its overview dashboard brings resident, unit, staff and work-request information into a single view, with tables and charts that help managers see the activity behind each building.

Rules that can be configured for each property

The RIO platform supports project-specific modules, rules and permissions. The presentation also sets out options for fees, amenity bookings, language support and system connections.

Amenities and fees

Booking approval rules, shared amenity spaces, deposits and refunds, automatic fee generation, payment reminders and PDF fee statements in the app.

Project access and resident services

Permissions at project level, login with a one-time password, multiple languages and reminders for upcoming amenity bookings.

Reporting and integration

Support for embedded Power BI dashboards and connections to other systems through APIs and software development kits.

Leasing and unit availability

Keep the unit record in view throughout the leasing process

Leasing staff need to know which units are available, what a prospective tenant is looking for and where each agreement stands. The RIO Leasing CRM shown in the presentation supports enquiries and client records, unit matching, digital proposals, site visits, reservations, lease agreements, payment schedules and commissions.

Sales availability

See which units are sold, reserved or available

Sơn Kim Land’s sales stacking plan arranges units by floor and uses distinct statuses for sold, booked and available apartments. This gives staff a view of the unit’s sales status when handling a reservation. It is a separate view from the leasing and occupancy plan below.

  • Booked / reserved
  • Available

Leasing unit management

Check availability, then open the unit’s full record

The leasing stacking plan groups apartments by floor and status, including vacant, leased, internal use, showroom and out of order. Filters narrow the view by project, unit type, status and date range; leased units show check-in and check-out dates.

Opening a unit reveals its area, balcony size, asking rent, direction and facilities, alongside related activities, enquiries, agreements, site visits, reservations, guests, status records and documents.

Lease agreements

Keep contract details, payments and expiry dates together

The agreement record brings together the tenant and company, leased unit, contract dates, deposit, rent, fees, commissions and supporting documents. Staff can follow each payment period’s due date and status, alongside total rent, paid amounts and unbilled balances.

Project value

Connected leasing and resident service around the property record

Leasing CRM kept unit information, availability and the leasing process together. The property operations tools and Highgate resident app extended that information into the occupied building and its daily service work.

The result was a practical set of tools for different users: leasing teams could manage the commercial relationship, management offices could coordinate property work and residents could access everyday services through the app.
