Microsoft .NET Software Development

Ballard Chalmers delivers a bespoke Microsoft .NET application development service that brings into reality the ambitions of our clients.

We work closely and consultatively so that the true business requirements are captured and analysed, ensuring that business processes as reflected in the software architecture and design are streamlined, efficient and flow logically. Proper design, architecture and overview are essential to developments which function well.

We are also extremely proficient in rescuing wayward software developments. Our experience ensures we are able to quickly identify and solve even the most complex of problems, explain what has happened, and how to fix it. We can either do the fixing directly, or we can work alongside your in-house team.

Our software engineers and consultants can help you with:

  • Custom building new high-performance applications to help you innovate and disrupt your market
  • Custom software development for cloud, on-premises and mobile applications
  • System re-engineering – upgrading and migrating legacy applications to the cloud
  • Migrating between versions
  • Maintaining and supporting new or existing custom .NET platforms
  • Integrating cross-platform applications

The development of the Oyster card system, with contactless payments and other features, was a massive .NET development, involving enormous data volumes and requiring the best development team…Ballard Chalmers contributed to the success of this project by supplying critical resources.

We will experience net savings after eliminating all three legacy document management solutions. Also, transferring data from one of the large, on-premise systems will decrease the risk of the system failing. Document storage is critical to our industry, and the business will be safer once these documents are transferred. Our IT team couldn’t have accomplished these goals without the support of Ballard Chalmers—they’ve had a tremendous impact.

CIO – United Living

The best result of their work recently is the portal itself. Until the recent MVP [minimum viable product] went out, we were unable to make emergency bookings through the system. They’ve really improved the functionality and our ability to work with other installers.

Project Manager – OVO Energy

Since the original phase 1 launch, the number of accounts worked by the team has increased by 250%, successful outcomes by 137%, payments by 152%, among many more positive stories. While headcount has remained fairly static, these improvements have been heavily influenced by process and system improvements that we’ve put in place together.

Business Analyst – Energy Services Company

Ballard Chalmers built a .NET/SQL application for one of our Fortune 500 clients that totally exceeded expectations. They rapidly turned complex business processes and an SKU list of thousands into an easy to use application that enabled our client to run a very successful partner awards programme.

Managing Director – Mason Zimbler

Over the past few years Ballard Chalmers has consistently surprised me with effective and economic solutions to difficult briefs, especially when dealing with the upgrading and integration of legacy systems. Their new builds are also excellent, and I would recommend them without hesitation.

Account Director – Caburn Hope

Ballard Chalmers has consistently provided a service that has matched or exceeded expectations within the agreed budget and timescale. They were receptive to our on-going suggestions and changing requirements and able to act promptly throughout. We look forward to working with them more in the future and would recommend them highly.

Director – Fenix Insight

Before partnering with Ballard Chalmers Ltd, we were struggling to roll out enough updates. Now, we’re releasing changes and improvements every other week. We’ve pushed out more updates in the last six months than we have in the last three years.
