What are the key differences between ERP and MRP systems?
In short, both MRP and ERP systems are pieces of software that help you to run your business better based on historical information, forecasting algorithms and your chosen business priorities. The key difference is the scope; MRP has a much narrower, manufacturing-centric focus than ERP, which provides business-wide benefits as well as supply chain management. To give you a better understanding of the components of each, and to help you to decide which one might be right for your company, we’ve set out some of the detail below.

ERP systems integrate every piece of the complex jigsaw that makes up a manufacturing business. Data from one part of the business can accurately inform decisions taken elsewhere. This means that real costings taken from manufacturing and purchasing can be used to generate accurate quotes at chosen margins with realistic lead times, even running ‘what-if’ scenarios within the scheduling software to understand the impact of new demand on the existing plan.

The accounts team can see a full breakdown of current and historic customer purchases and trends in receipt of cash, allowing for open discussions with customers using accurate information, as well as forecasting and effective management of creditors. Business leaders can use insights to drive strategic decisions; the data available from a full ERP system provides a holistic picture of the company’s – as well as its customers’ and suppliers’ - activities. If your objective is supply chain management, an ERP system will give you the tools to achieve absolute control across the whole process, from the supply of raw material to the logistics of delivery. An MRP module is a crucial component of ERP systems, but it is not the sole focus of the solution.
MRP, however, is a tool largely used by production and operations teams to manage the manufacturing and purchasing areas of the business for efficiency gains. It enables the manufacturing facility to meet customer demands whilst meeting stocking KPIs and purchasing economically. Customers benefit from your business’ visibility and control, whilst you will see an improvement in cash flow and a reduction in manufacturing delays. MRP is a stand-alone item of software, so that whilst other departments can use the data (for example, for accurate costing or for chasing invoices), the data will not be linked to their databases. Whilst MRP systems can often be integrated into other software through imports and exports of relevant data, it is a more difficult process than with ERP, which has been developed with total integration and data-flow in mind.
