Case Study: DoorBill – Revolutionizing Property Management with a Smart, Cost-Effective Solution


Client: Mission Workspace

Industry: Property Management

Solution: DoorBill – Custom Software for Smart Lock Access and Rental Billing


Mission Workspace, a player in the property management arena, encountered a prevalent challenge: integrating a smart lock and co-working software solution that was efficient and economically feasible. Conventional solutions were overly complex and prohibitively expensive, with quotes ranging between $50,000 and $100,000. Enter Doejo, with their tailored, streamlined solution: DoorBill.


Mission Workspace needed a system for a 50-unit office building that could manage smart lock access and rental billing seamlessly. The market’s fragmented solutions led to operational inefficiencies and excessive costs. The client sought a solution that was straightforward, effective, and affordable.


Doejo sourced an economical Bluetooth lock, initially priced at $250 retail, and obtained it at $150 wholesale. Including a locksmith fee of $50 per door, the hardware expenses were significantly reduced.

The pivotal component was the development of DoorBill, a bespoke software solution tailored for Mission Workspace. DoorBill integrates with the smart locks, facilitating efficient tenant access management and rental billing. Key features of the solution include:

  • Simplified Operations: A unified system for access control and billing.
  • Cost-Effectiveness: Drastically lower initial and recurring costs compared to other market options.
  • Scalability: Versatile for various property types, including office spaces, multifamily units, and storage facilities.
  • User-Friendly Interface: An intuitive design for both administrators and tenants.


Implementing DoorBill in the 50-unit office building marked a significant advancement in operational efficiency and cost-effectiveness:

  • Reduced Costs: Hardware and installation expenses were a fraction of those quoted by other providers.
  • Enhanced Accessibility: Streamlined tenant access, eliminating the need for conventional keys or intricate access systems.
  • Efficient Management: A simplified rental billing process, leading to time savings and reduced errors.
  • Positive Feedback: Tenants valued the straightforward access and billing system.
