Building the future of virtual front door interaction
QBell is on a mission to upgrade the world’s front doors.
The requirement
Smart home technology has become a standard part of modern living — with connected heating, lighting and security now commonplace. Yet the front door remains one of the least digitally optimised parts of the home. Traditional smart doorbells are often expensive to install, require maintenance, and raise privacy concerns.
QBell changes this.
Using patent-pending QR-based technology, QBell creates a real-time, secure and anonymous connection between visitors and residents, with no hardware installation and no app required for visitors. A simple QR code at the door becomes a virtual doorbell, allowing instant messaging, delivery instructions and remote access to the homeowner.
As online shopping and home delivery continue to grow, the front door has become a major bottleneck. Missed deliveries, time-wasting knock-and-wait cycles, and privacy concerns all create friction for households and logistics providers alike. QBell solves this by enabling seamless, remote interaction at the exact moment it matters.
The project at-a-glance
- Shaping the product vision and roadmap to transform a patent-pending concept into a scalable SaaS proposition.
- Designing a high-availability AWS architecture to manage secure, real-time messaging between visitors and residents.
- Creating a frictionless mobile-first experience requiring no hardware installation or visitor app downloads.
- Delivering end-to-end UX/UI design and prototyping to validate user journeys in real-world environments.
- Aligning technical delivery with commercial growth through a strategic long-term investment partnership.
Our solution
QBell had a powerful idea:
A low-cost, privacy-first, zero-installation way to turn any front door into a smart door.
But turning that idea into a scalable SaaS platform required:
- A secure cloud architecture
- A frictionless user experience for both residents and visitors
- A mobile-first interface
- A product strategy that could support growth, partnerships and commercial rollout
QBell needed more than software — they needed a product partner.
IDS partnered with QBell across strategy, product, design and delivery to bring the platform to life.
What IDS delivered
Business & product strategy
IDS worked closely with QBell leadership to shape the product vision into a viable, scalable SaaS proposition. This included:
- Business and product consultation
- Feature prioritisation and roadmap planning
- Commercial and platform strategy
This ensured the technology was aligned to QBell’s long-term business goals, not just short-term development.
Mobile and web user experience
The success of QBell depends on how easy it is to use at the front door — often under time pressure.
IDS delivered:
- User experience strategy
- Mobile-first interface design
- Visitor and resident user journeys
- Intuitive chat-based interaction flows
The experience was designed so that a first-time visitor can instantly understand what to do, while residents get a fast, clear and secure way to respond.
SaaS platform & cloud infrastructure
IDS designed and delivered the complete QBell digital platform, including:
- A secure, scalable SaaS architecture
- AWS cloud hosting and infrastructure
- Real-time messaging and connection handling
- Privacy-by-design data flows
The result was a high-availability cloud platform capable of handling real-time conversations between doors, visitors and residents — at scale.
Investment in the product
IDS didn’t just act as a supplier, they invested in the product itself.
This aligned IDS with QBell’s success and reinforced a true partnership model rather than a transactional delivery relationship.
Design, innovation and prototyping
IDS helped QBell explore, validate and refine the product through:
- Innovative concepts and ideation
- UX and UI design
- Interactive prototypes and demos
- Proof-of-concept installations
This allowed QBell to test ideas in the real world – at real front doors, before committing to full production builds.
The results
Together, IDS and QBell created a new category of smart-door technology:
- No installation
- No visitor app
- Strong privacy by design
- Real-time interaction
- Built for mass adoption
QBell is now positioned to scale across residential, multi-occupancy, and delivery-service use cases — turning the humble front door into a connected digital touchpoint.
We ourselves experienced first-hand that this is a real pain for home delivery services when we ran an online coffee shop. One day we connected the dots — why can’t there be a virtual doorbell instead of a traditional one? And now we have QBell.
