Case Study - Self Storage Web Application Development

Business Challenges


The self-storage industry uses padlocks to ‘overlock’ a customer’s unit when the customer is late in payment of their rent. The overlock denies the customer access to their possessions until they pay their dues.

The existing process for removing these padlocks was inefficient. Specifically, it required personnel from the property to physically go to the storage unit to remove the overlock.

If the customer Wanted the lock removed after business hours,then either the customer is out of luckor the facility should incur added man-hours to dispatch personnel back to the facility to remove the lock.

Flatworld built a PaaS web application


Flatworld built a PaaS web application for self-storage operators to deliver a Padlock combination to a customer so they may independently remove overlocks which are Combination Padlocks.


The web application has the following features:

  • Multi-tenant architecture
  • Facility management
  • Overlock management and unlock combination code management
  • Bill plans management
  • Audit logging
  • Call-center agent interface
  • Invoice management (Integration with FreshBooks)
