Colas Ireland, a subsidiary of Colas SA, is a leader in the construction and maintenance of transport infrastructure within both the Republic of Ireland and Northern Ireland. Its parent, Colas SA, a subsidiary of the Bouygues Group, is a world leader in this area with 55,000 employees in more than 50 countries on five continents. The Colas Group works in every business segment involving the construction and maintenance of roads, along with all other types of transport infrastructure as well as urban development, through two operating units: Roads, its core business, and Specialized Activities to expand the range of offers. Through its projects and its innovations, Colas aims to meet the modern world’s real needs for mobility, urban development and environmental protection. Colas Ireland mirrors this at a national level with over 250 employees across 18 local business units and branches.


Colas wanted to simplify consolidation and group reporting by having consistent accounting set-up across their Irish operations. Colas Ireland in conjunction with their parent, Colas SA, selected ProStrategy to deploy Microsoft Dynamics NAV, a fully integrated ERP solution, to replace their former accounts system. Looking to improve current processes, reducing data entry and MS Excel reliance, ProStrategy set about implementing Dynamics NAV across 14 of the Colas Ireland locations.


Microsoft Dynamics NAV empowers Colas to work on an integrated hosted solution allowing them to have real time visibility of their stock level and expected revenues. It greatly reduced the amount of data entry required and errors at billing stage having data entered correctly at order stage and process purchase invoices directly from PO data creating work efficiencies. Dynamics NAV closes the loop by reliably handling complex pricing scenarios required by customer tenders. Colas reported improved staff productivity which significantly reduced data and role duplication. They now have consistent and comparable data from companies across their Irish operations leading to increased cost control and better decision making across the business. Colas SA, as parent company, were keen to implement an updated accounts package across their Colas Ireland operations with the improved data consistency and internal efficiencies brought by Dynamics NAV seen as big positive.


After months of challenging work, the project went live in phases between October 2016 and early 2017. The huge effort of both the ProStrategy and Colas project teams was realised when, within a brief time after the go live date, the business was seeing some huge benefits. ProStrategy’s differentiators came in the form of its in-depth knowledge of both NAV and the Irish accounting and tax environment provided by Dynamics NAV Consultants and Colas Project Manager. ProStrategy were able to advise on both the efficient hosting and IT set-up as well as the more detailed accounting set-up required to maximise the benefits from implementing Dynamics NAV. Prostrategy’s project team’s NAV experience and expertise were key in having a successful Go-Live and have been invaluable in providing post Go-Live support and assistance. Colas Ireland’s proximity to ProStrategy’s office base allowed for meetings to be easily arranged while staff training was suitably and efficiently designed to maximise the benefit for end users. The flexibility of NAV in adapting to complex customisations in areas such as sales pricing and invoicing combined with the most suitable partner has lead to a very positive project outcome.
