There is more to us

On top of an exceptional team, OneOverZero usually resorts to its academic and partner connection network for complementing its know-how and manpower should this be required. The strong bonds to ETHZ, EPFL and world class partners allow us to complete our knowledge in order to cover all aspects of a project, from design to coding, from UI/UX to management.

The right tools for the jobFor businesses and consumers

Business-to-employee communication

Enterprises with a large number of full- or part-time employees face the challenge of optimizing their communication with the workforce: availabilities and absences, planned assignments and their execution reports, submission and processing of forms (e.g. expense reports) pose a considerable burden to the back-office.

Our business-to-employee portal takes care of these aspects by consolidating all communication workflows into an easy-to-use, scalable, bring-your-own-device web/mobile application. It is cross-media by design and supports modern web browsers, tablets, smartphones, featurephones, email, calendaring applications and SMS.


Sales quotation generation

We design and implement server-based applications that consolidate, streamline and mobilise the sale of products and services.

With their notebooks or tablets, field-forces can browse product catalogues, spec a formal proposal and quote prices under the strict guidance of the server-side business logic. The quotation generation is complemented by modules for customer relationship management, acquisition of used equipment, financing, leasing, production schedules, service level agreements, etc.


Automation of field-forces

The optimal deployment of field-forces, e.g. field technicians, is a common challenge of service-oriented enterprises. For these scenarios we realized an application framework for the automation of service activities on top of which customised solutions can be implemented.

The framework supports the end-to-end process bound to service activities: an initial inbound call received by the call-center triggers the data gathering process relevant to the active case, which is presented to an operator who can select a technician and schedule an on-site intervention; the personnel in-the-field uses its mobile phone or notebook computer for acknowledging the activity and reporting duties, which are immediately sent to the guidance system, in real-time; back-office verifies the reports and passes them to the company ERP system, where they can be post-processed for billing and statistics purposes.


Time reporting

Zeitr is our web and mobile application for time reporting. It tackles the two major challenges faced by companies across many business segments: booking of time on a per-project basis, reporting of activities on a per-day basis.

The very loose application business logic allows for a wide range of usage patterns: from unstructured to semantics-rich, from flat to hierarchical. This flexibility is ensured through a smart tagging mechanism, which empower the users with a simple yet powerful feature.

Zeitr is offered on a usage license basis (SaaS) and is remarkable for its high ROI and almost inexistent up-front-investments required.


Personal finances

Monsai is a web application for managing personal finances. At its core, smart algorithms automatically categorize and aggregate expenses. On its surface, its compelling user-interface presents data in a visual and fun way.

Monsai helps us (and you, too!) combine the different accounts and credit cards, while letting us discover where all the money goes.

While in other countries similar applications have already won the heart of many clients, Monsai is the first application of its kind to be released in Switzerland with support for Swiss financial institutions.


Native, hybrid, and web frameworks

The many projects we undertook during the past couple of years prompted us to synthesize a small set of core functionalities that are common to every mobile/web application. This yielded three frameworks (native, hybrid, web) that relieve us—and our clients—from all the heavy-lifting and boilerplate code that is needed for modular and secure applications for both mobile and web.

The frameworks are owned by OneOverZero and are used today by many important Swiss financial institutions, looking for a robust, audited, penetration-tested, and mature foundation upon which mobile services can be custom built.


Android mobile printing

We all strive for a paperless workflow. And yet reality (and legal requirements) sometimes work against us. When this need arises, we use our mobile printing framework for Android devices. The software works as a generic, independent module which can be easily integrated into third parties applications. It works with the majority of portable printers available today on the market and can address the most complex requirements.


Our technology meets your challenges We listen, we build, we deliver

Services

OneOverZero and its employees have more than 100 man-years of experience in the design and implementation of complex, dependable, high-performance, enterprise-class IT solutions and, in particular, in the realm of mobilization of business processes.

During our first seven years of activity, we completed a significant number of high-profile, mission-critical projects on-time, on-budget, using best-of-breed technologies to the highest customer satisfaction.

Clients that elected us as their partner choose engineering excellence and a competent team that help them think outside the box, characteristics that few IT companies share and which ultimately result in high efficiency, performance and return on investment.



Analysis

We are proficient in a wide range of disciplines and we take pride in tackling the hardest problems. We help our clients take advantage of technology by choosing the best solution for the challenges at-hand, devising the best mapping for the given use- or business-cases, realizing their visions for the constantly changing business and technology landscape.

Implementation

It is our firm belief that a talented engineering team that is able to work shoulder-to-shoulder with the client is paramount to the successful realization of demanding projects. Geographical proximity, language affinity, 24/7 on-site availability of every member of the team, valuable intellectual contributions and commonality of goals complete the formula.

Support

We know enterprise requirements: availability and security. We confront the first with scalability, redundancy and resilience to errors. We attack the latter with best-of-class methods and algorithms. Our methods have been audited, our solutions penetration tested many times over. And if that does not suffice, we are available 24/7/365.
