UK Engineering Organisation Transforms Operations with Business Central SaaS and Tasklet 

Customer Overview

A long–established UK engineering organisation delivering specialist solutions across aerospace, energy, utilities and other technical sectors required a modern, flexible and reliable business system to support evolving operations. The organisation needed to improve warehouse processes, reduce manual effort and remove the limitations of its ageing on–premises ERP platform. To achieve this, it partnered with Mercurius IT to move from Microsoft Dynamics NAV to Dynamics 365 Business Central SaaS, supported by Tasklet Mobile WMS and tailored enhancements.

Business Challenges

Performance Concerns and On‑Premises Costs

NAV performance was declining and running the system on‑premises meant ongoing expenses for infrastructure, updates, maintenance and IT support. 

Mobile NAV Not Fully Meeting Warehouse Needs

The warehouse team needed a more capable and user-friendly mobile solution to support daily activities. Mobile NAV did not fully meet their workflow requirements. 

No Functionality for Multi‑Line ID Label Printing

The team required the ability to print ID labels for multiple lines at once. NAV lacked this functionality which led to manual workarounds and repetitive effort. 

Rigid Licensing Structure

NAV licensing did not offer the flexibility to scale licences up or down as needed, making changes slow and costly. 

Manual Version Updates

All updates in NAV had to be performed manually which required additional time, planning and budget. This often delayed upgrades and limited system improvements. 

The Solution

Migration to Business Central SaaS 

Mercurius IT migrated the organisation from NAV to Microsoft Dynamics 365 Business Central SaaS. This move removed the need for on-premises servers, provided modern cloud functionality and improved system reliability. 

Implementation of Tasklet Mobile WMS

Tasklet was introduced to replace Mobile NAV. Tasklet offered a robust, intuitive mobile solution that aligned with the organisation’s warehouse processes and significantly improved usability. 

Custom Multi‑Line Label Printing

Mercurius IT delivered a bespoke enhancement that enabled the warehouse team to print ID labels for multiple lines in a single action, reducing manual steps and improving productivity. 

Flexible Licensing

With Business Central SaaS, the organisation can easily add or remove user licences on a prorated basis at any time. This offers far better control and cost efficiency. 

Automatic System Updates

Updates are now applied automatically by Microsoft, ensuring that the organisation always operates on the latest version without manual intervention or additional project costs. 

Results and Benefits

Reduced Costs and No Infrastructure Overheads

By moving to Business Central SaaS, the organisation eliminated the need for on-premises hardware, associated maintenance and manual update costs. 

More Efficient Warehouse Operations

Tasklet delivered a stronger, more modern warehouse management experience. Staff can now complete scanning tasks quickly and accurately, improving overall operational efficiency. 

Time Savings Through Automation

The custom multi‑line label printing solution removed repetitive manual steps and allowed the warehouse team to work more productively. 

Greater Licensing Flexibility

The organisation can now scale licences according to operational demand, ensuring it only pays for what it needs.

With automatic updates, the organisation benefits from new features, improved performance and enhanced security at no additional cost or effort.
