growth since using BigChange




A start-up business with ambitious expansion plans. A need for the correct working practices to allow managed & sustainable growth.


Working practices and management structure of a large company from day one evidenced by an 800% growth, diversified product and service offering and ambitious plans.

Having seen business growth of 800 per cent since implementing BigChange’s field service management software, Crucial Engineering now plans to build on this success by increasing its geographical coverage using the BigChange Collaboration Network. The Network allows it to connect with trusted sub-contractors, also using BigChange, to operate beyond the constraints of its existing workforce whilst maintaining performance and service KPIs.

Paul Van Heeswyk, Managing Director and founder of Crucial Engineering knew from the start how he wanted the business to run and adopted BigChange after just three months of trading. He would load jobs onto the system in the morning, do the work during the day, and complete reports and invoices while he ate his dinner.

“Despite being mocked for creating more work for myself, I was adamant, if I wanted the company to succeed and flourish, I needed to put in place the correct working practices, that would allow managed expansion, underpinned by the highest levels of efficiency and service.

“BigChange has given me this and more!” Paul Van Heeswyk, Managing Director & Founder of Crucial Engineering.

Using BigChange, which incorporates a mobile workforce app, customer relationship management (CRM), job scheduling, live tracking, resource management, financial management, and business intelligence, Crucial has had the working practices and management structure of a much bigger company from the start. This has mitigated many of the growing pains that companies like them have to go through and has meant that Crucial has been virtually paper free for more than 6 years. The cloud-based system is used by engineers in the field, workshop, and production staff, the back-office support team, and management, to provide end-to-end automated workflows from initial enquiry through to job completion reporting, invoicing, and customer care follow ups.

The BigChange Collaboration Network has also allowed Crucial to identify and engage with other BigChange users. With Crucial, its new partners, and existing contractors, all using the same reporting platform, the customer receives a seamless service and management has total visibility of the mobile operation. By sharing existing and proven digital workflows Crucial can also maintain its first-class customer service levels and performance targets, regardless of who is actually delivering the work package.

“Like us BigChange continues to evolve and adapt. During the last few years, we have had to diversify our product and service offering and BigChange has continued to deliver.

“Using BigChange we have proven, that in spite of difficult or challenging circumstances, we can provide the highest levels of choice, quality and service, and we are confident that we can build on our growth profile and achieve our ambitions for a UK wide operation.” Paul Van Heeswyk, Managing Director & Founder of Crucial Engineering.


Crucial Engineering was established in 2016 by current Managing Director and owner Paul Van Heeswyk. Originally specialising in automated access systems including industrial doors, automated gates and barriers, and loading bay solutions, Crucial has added an aluminum fabrication division and a glazing production division to its service offering, which includes manufacturing and installing aluminum curtain walling, shopfronts, windows, and doors. Working with blue chip clients such as Audi, Arnold Clark, CBRE, and Travis Perkins, Crucial is proud to maintain the highest quality of customer service recognised with successive Build Construction and Engineering Awards in 2020, 2021, and 2022 and a Digital Enterprise Top 100 rating in 2020.
