The Problem

EPC was operating on Microsoft Great Plains, a legacy ERP system approaching end of life.

The platform was increasingly difficult to maintain, lacked flexibility and could not support the evolving needs of the business.

An attempt had already been made to upgrade. Over an 18-month period, EPC worked with a previous supplier to migrate to Microsoft Dynamics 365 Business Central. Despite significant investment, the project failed to deliver a useable system.

The business was left with:

  • No working replacement for a legacy ERP system

  • Significant sunk cost with no return

  • Growing operational risk as Great Plains approached end of life

  • Reduced confidence in delivering a successful transformation

A reset was required.

The Challenge

The project was not starting from a clean slate.

Time, budget and internal confidence had already been impacted by a failed implementation.

Any new approach needed to demonstrate progress quickly and rebuild trust.

Replacing a business-critical system ERP systems sit at the centre of operations. Any replacement needed to support:

  • Sales order processing

  • Invoicing and quoting

  • Inventory and stock management

  • Financial reporting

Failure to deliver would directly impact day-to-day business operations. Supporting a connected business model EPC’s operations are closely linked with CSI, particularly through equipment lifecycle and inventory grading.

The ERP system needed to integrate with CSI’s proprietary grading platform to ensure accurate categorisation and valuation of assets.

The Solution

The Curve delivered a full Microsoft Dynamics 365 Business Central implementation, replacing a failed ERP programme with a structured, scalable solution. Core business processes including sales, invoicing, inventory management and financial reporting were configured from the ground up, supported by custom extensions where required. The platform was integrated with CSI’s proprietary equipment grading system to ensure accurate asset management across the lifecycle. By replacing fragmented systems and a legacy platform with a single, integrated ERP, EPC improved operational control, reduced risk and established a foundation for future integrations and growth.

Our Approach

We reset the programme, starting from first principles to deliver a clean, structured Business Central implementation focused on stability, integration and long-term scalability.

Starting with discovery and clarity

EPC approached The Curve in June 2024 to run a structured discovery.

The focus was to assess the current state, understand what had gone wrong previously and define a clear, achievable path to Business Central.

Rather than continuing from a partially delivered system, we made the decision to start again from first principles.

Delivering a clean implementation

We implemented Microsoft Dynamics 365 Business Central from scratch, ensuring that core business processes were correctly configured from the outset.

This included:

  • Sales order and invoicing workflows

  • Quoting and customer management

  • Inventory and stock control

Financial reporting and data structures

Where Business Central could not meet requirements out of the box, we developed custom extensions to support EPC’s specific operational needs.

Integrating critical systems

A key part of the implementation was integrating Business Central with CSI’s proprietary equipment grading system.

This ensured that inventory could be accurately categorised, valued and managed across the asset lifecycle.

Building for scale, not just delivery

The platform was designed not just to replace Great Plains, but to support future growth and integration.

This included preparing the system for integration with external platforms such as:

  • Shopify

  • Stripe

  • PayPal

  • ShipStation

  • Multiple internal systems

The Results

01.

Successful delivery after previous failure: A fully functional ERP system was delivered in 5–6 months, compared to 18 months with no outcome from the previous supplier. This restored confidence in the programme and provided immediate operational value.

02.

Following a previous failed investment, EPC achieved a complete, working system in approximately one third of the time, delivering significantly greater return and time to value.

03.

Modern, scalable ERP platform: Microsoft Great Plains was successfully replaced with Business Central, providing a modern, supported and flexible platform for the business. Integrated operational ecosystem The integration with CSI’s grading system ensures that inventory is accurately managed across the asset lifecycle, strengthening the connection between the two businesses.

04.

Foundation for ongoing growth: The success of the project has already led to: Additional integration projects Expansion into new system connections Introduction to the US division of the business

05.

Seamless financial system migration at year-end: EPC completed a seamless year-end migration from Microsoft Great Plains to Business Central, closing one financial year on the legacy system and starting the next entirely on the new platform without disruption.

What began as a recovery project became a complete operational reset. By replacing a failed ERP programme with a structured, delivery-focused approach, The Curve enabled EPC to move from uncertainty to a stable, scalable platform. The business now has a system that supports its day-to-day operations, integrates with critical partners and provides a foundation for continued growth. With further integrations already underway, Business Central is no longer just a replacement system. It is the core platform enabling EPC’s future operations.

Their Thoughts

“After 18 months and significant investment, we still didn’t have a working system. The Curve came in, reset the approach and delivered a complete implementation in a fraction of the time. It’s given us the platform we needed and the confidence to keep building.”
