“People didn’t think this type of connectivity was possible within this budget. But through the quality of the engineering of Transparity Ballard Chalmers, the quality of the development team fronted up with the PM alongside the AppCan input in terms of UAT and direction, we successfully delivered on time and in the budget as stated.”

Co-founder and Director – AppCan

In Brief

After having worked with the AppCan platform for four years, 2022 brought about a new focus with Azure Integration Services Development. This project saw the development of an integration hub for use by one of AppCan’s clients.

Using the hub, AppCan’s client was able to move away from their reliance upon an expensive legacy Salesforce system within their business, using a percentage of their annual savings to fund the development of the integrated system solution.

The Client

AppCan is a software-as-a-service company working in the utility construction industry. The AppCan platform is a web and mobile data collection and documentation distribution platform for field workers. Specifically, for businesses that require their field-force teams to either collate and submit relevant job-related data or to receive/access documentation pertinent to their field activities.


As AppCan’s client base expands, some users require specific functionality. In this case, AppCan was approached by an existing client – a large gas services company – looking for a development partner as it had won the delivery lead framework contract bid for London. The previous framework contract, lasting 8 years, had come to an end, and the systems developed for that framework, based on Salesforce and Tableau, no longer delivered the new contract’s requirements.

AppCan then brought in Transparity Ballard Chalmers to the discussion, looking at whether what was required was possible within the available budget. With CTO Geoff Ballard’s direction and the whole team’s enthusiasm and confidence that we could do it, the project was ‘green-lit’ to proceed.


The Integration Hub

The integration hub is a collection of Azure services and is hosted in AppCan’s Azure tenancy. There are a number of integrations between the integration hub and the AppCan platform. These are:

  • AppCan Global Data Fields: Azure Functions app, integrating with the existing AppCan API and updating AppCan with data from Street Manager (the UK National Street works and Permitting Database) and Ctrl-Hub (a Works Management System)
  • AppCan Data collector data: Azure Functions app, integrating with the existing AppCan API and syncing data from AppCan into the Integration Hub
  • Notice & Permit PDF generation: Azure Functions app with an HTTP trigger to generate basic PDF documents for a specific notice/permit on demand.

Other outside integrations included in the hub are:

  • Integration with Street Manager: Azure Functions app to pull data from Street Manager API into the Integration Hub
  • Integration with Ctrl-Hub: Azure Functions app to pull data from Ctrl-Hub API into the Integration Hub

Other parts of the application include:

  • All data held in the integration hub is stored in a SQL Azure database
  • Each integration records successful and failed events to Azure Application Insights
Integration Hub Development

Web UI application

As part of the integration hub, a Web UI application was developed to support any manual interaction with the data held in the integration hub. This application has the following functions:

  • Authentication
  • User management and role assignments
  • Bid List upload function
  • Upload Scheme Procurement Status
  • View and Edit Bid List
  • View Reinstatements and Capture/Upload Final measures
  • Service Card and CSE Card validation

It was implemented as an Angular SPA (single page application) for the UI, with a .NET Web API backend.


By partnering with AppCan and by extension Transparity Ballard Chalmers, this client was able to unshackle itself from a large and expensive system that didn’t do exactly what was needed. Now it’s been replaced with something that is totally within its control to change, meaning no wait time or punitive costs. So, year on year, the client is better off with both the benefits of the changes and a significant reduction in annual running costs.

With gas networks across the North West, East Midlands, East of England and North London all now using the Integration Hub after only a few months since go-live, the project has been a great success.


In an interesting aside, once the development budget and timescales had been established by Transparity Ballard Chalmers, there was an initial challenge, from the client, that the project, given its scale and complexity, could not be delivered on time and on budget. Both confidence and reputation soared when both targets were met!

The development of the integration hub took 6 months and £125,000 to build and currently ticks along at less than £10,000 a year in Azure and support costs. One year of cost savings, achieved by leaving Salesforce, paid for the project, and the client is now accruing year-on-year savings for the remainder of the contract term.

Additionally, the company is using four partitions of the Hub across four geographical areas, meaning they’ve now internally spread the initial £125,000 investment across four cost centres. There is no other product on the market that can compete with that.


The key point is does it work – yes! It is already deployed across three businesses and four geographies since the product launched in July.  To date, the hub has received, validated, and processed in excess of 400,000 field-force transactions, across three different engineering processes.

Here we give just one example of how the system is used.

The OFGEM (Office of Gas and Electricity Markets) pays money to the client based on how many domestic/non-domestic gas services they replace. Each white row is associated with one or more pink rows and each processed white row attracts an OFGEM payment.

Looking at how that translates into money for the client, we have to consider what has been accepted.  Since August there have been over 75,000 accepted service cards across all four regions; at circa £500 per card, around £38m of transaction value!

Additionally, reporting ability, via access to the integration hub tables using Power BI, has dramatically improved; the client’s internal team of analysts can now deliver comprehensive dashboard summaries that track process performance.

The client has full control of the AppCan mobile platform and integration hub too, meaning that outsourced development, tweaks, or consultancy is not a constant requirement and features are able to be added internally if required.

For AppCan’s Client, this is a significant departure from the use of large legacy CRM systems which are expensive to implement, run, and make changes to. Effectively we have delivered a high-quality works management system UI, without any of the attendant costs of larger mainstream products.

The Integration Hub for AppCan

 “The Integration Hub is a great addition to the main portfolio of AppCan Web and AppCan Mobile. After the initial build for one client, further clients have already picked it up, seeing the huge value add.

Additionally, the integration between these apps and the hub has helped introduce companies into licences for AppCan web and mobile, adding to licence revenue for AppCan.

Lastly, the end client was nervous at the beginning and then they started to see the product working early on, and now they are confident enough that they are using AppCan (with BC as the development partner) as an extension of their IT team. BC has never let us down on cost and our confidence in their engineering capability means we can take on other large projects for our clients.” Co-founder and Director AppCan
