Choosing an ERP system is one of the biggest decisions a manufacturer can make. Get it right and it can help improve visibility, reduce manual processes, tighten coordination between departments, and give teams better information to work with. Get it wrong and even everyday tasks can become harder than they need to be.
Many manufacturers start the process in the same way. They build a shortlist of familiar names, compare feature lists, sit through demonstrations, and assume the larger vendors are likely to be the safest option.
That approach seems sensible at first. But choosing an ERP based on name recognition alone can create problems later.
The reality is that manufacturing businesses do not all operate in the same way. A company producing standard products at high volume has very different requirements from a business managing engineering changes, project-based work, and customised orders.
It is not unusual for two manufacturers of similar size to end up with completely different ERP shortlists.
Manufacturers need to consider the size of their business, but also the type of manufacturing they do. A smaller custom manufacturer may have more complex ERP needs than a much larger company making standard products at high volume. Both factors matter, but the way a manufacturer actually operates is often the better guide when evaluating ERP systems.
We look at how manufacturers can evaluate ERP systems based on company size and manufacturing environment, why ERP projects often run into problems, and what manufacturers should ask vendors before making a decision.
Most ERP projects do not start badly. Manufacturers usually begin with clear goals: they want better reporting, more visibility, less manual work, and stronger coordination between departments. The problems often appear later, once the system has been selected and the business starts seeing how well it actually fits day-to-day operations.
Sometimes a manufacturer chooses a system because it appears powerful, widely used, or suitable for businesses across many industries. On paper, it may seem like a safe long-term choice. But once implementation begins, the gaps can become much clearer. Engineering teams may still need to re-enter information manually. Production schedules may be difficult to manage. Teams may continue using spreadsheets because certain processes are awkward or time-consuming inside the ERP itself.
The problem is not always that the software is poor. More often, the software was designed around a different type of operating environment. An engineer-to-order manufacturer with 120 employees may need more specialised manufacturing functionality than a repetitive manufacturer with 500 employees. Looking only at company size does not tell the full story.
Manufacturers need to understand not only whether the software has the right features, but also how well it supports the way they actually work.
Company size still matters when evaluating ERP systems. Smaller manufacturers usually have different priorities from larger organisations, particularly around resources, complexity, and implementation requirements. Company size remains an important part of ERP selection, but it should be considered alongside the way a manufacturer actually operates.
Smaller manufacturers are often trying to bring structure to everyday operations. Many are moving away from spreadsheets, disconnected software, or accounting systems that were never intended to manage production environments properly.
The main goal at this stage is often straightforward: make daily work easier and improve visibility.
For smaller manufacturers, the priorities are often centred around making day-to-day operations easier to manage. Ease of use, implementation time, and affordability are usually important considerations, along with improving visibility between departments, reducing manual work, and gaining better oversight of inventory and production activities.
Smaller businesses also often have limited internal IT resources, so support and implementation become important considerations.
Useful questions to ask an ERP vendor include:
The best ERP for a smaller manufacturer is usually the one that gives teams more control without making processes more complicated.
As manufacturers grow, ERP discussions often start changing. The conversation becomes less about solving isolated problems and more about keeping operations connected as the business becomes more complex.
There are more jobs to manage, production schedules become tighter, inventory becomes harder to track, and engineering changes can happen more often. This is often where generic systems begin to show their limitations. Departments can quickly become disconnected if information is not flowing properly between engineering, purchasing, production, inventory and finance.
Manufacturers at this stage should look carefully at practical manufacturing workflows rather than broad feature lists. It is worth asking how engineering revisions are managed, whether CAD systems can connect directly into the ERP, how flexible production scheduling really is, and whether the system can handle customised work efficiently. Manufacturers should also look at how visible job costs are during production and how much additional configuration would be needed to make the system fit their processes.
Vendor experience also becomes more important at this stage. Manufacturers should ask what types of manufacturing businesses the vendor typically supports, whether the implementation team understands manufacturing operations, and how often they work with businesses of similar complexity. It is also worth understanding how much core manufacturing functionality is built into the ERP, and how much depends on third-party tools.
At this stage, manufacturers often need more than software. They need a partner that understands manufacturing itself
Larger manufacturers may face a different set of challenges altogether. Multiple sites, standardised processes, reporting structures, governance requirements and broader operational complexity can all influence ERP selection.
Large ERP platforms may make sense in these environments. At the same time, bigger systems can also bring longer implementation timescales, larger customisation projects, more administration, greater training requirements, and more difficult user adoption.
Bigger does not automatically mean better. Even large organisations should evaluate how effectively a system supports real day-to-day manufacturing activity.
Company size tells part of the story. Manufacturing type often provides a much clearer picture of ERP requirements.
Two businesses with similar revenue and employee numbers can have entirely different operational requirements depending on how they manufacture products. That is why manufacturers should evaluate ERP systems based on how work actually moves through the business.
Engineer-to-order and custom manufacturers often deal with highly variable production environments. Customer requirements can change, engineering teams are closely involved, projects move through several stages, and custom BOMs and revisions are part of everyday work.
For these businesses, ERP fit often depends on how effectively information moves between engineering, purchasing, production, inventory and project management. Manufacturers should look closely at CAD-to-BOM integration, revision management, custom quoting, project visibility, flexible scheduling, job costing and long lead-time project management.
Useful questions to ask include:
For example, if engineers still need to manually rebuild BOMs after completing designs, unnecessary work and errors can quickly appear. For many custom manufacturers, a strong connection between engineering and production is often more valuable than a long list of generic ERP features.
Manufacturers operating in make-to-order or mixed-mode environments often deal with regular changes to schedules, customer priorities, and material availability. For these businesses, flexibility is usually one of the most important things to evaluate in an ERP system.
Manufacturers should look closely at inventory visibility, adaptable scheduling, purchasing coordination, production visibility, and planning tools. They should also pay attention to how easily production plans can be adjusted when priorities shift. In real manufacturing environments, plans rarely stay fixed for long, so ERP systems should help teams respond quickly without creating extra admin work.
Manufacturers producing standard products at high volume often focus more heavily on consistency, efficiency, and process control. Their ERP priorities may include production planning, inventory optimisation, procurement coordination, standardised workflows, reporting consistency, and operational scalability.
These businesses should look at how well the system supports repeatable processes, keeps materials moving, and gives managers clear visibility across production. It also needs to be practical for day-to-day users, because even strong planning tools can slow teams down if the system is difficult to use.
Manufacturers working in regulated industries, aerospace, defence, or similar sectors, often need stronger process controls, clearer documentation, and better visibility into how work is managed. Traceability, revision control, quality management, documentation management, audit readiness, and controlled processes may all need closer attention during ERP selection.
However, regulated manufacturers should avoid assuming that every large ERP platform automatically provides the best fit. Usability still matters. If the system is difficult for teams to work with, people may create manual workarounds outside the ERP, which can cause visibility, documentation, and process control issues of their own.
ERP demonstrations often focus heavily on polished feature presentations. Manufacturers should push conversations further. The goal is not simply to confirm whether a feature exists. The goal is to understand how the system works in a real manufacturing environment.
Some questions worth asking include:
Manufacturers should also ask vendors to demonstrate workflows that match their actual environment.
An engineer-to-order manufacturer should not settle for a generic demonstration. Ask to see engineering revisions, project tracking, scheduling changes, purchasing coordination and CAD workflows.
Those conversations often reveal more than feature lists ever will.
Manufacturers rarely struggle with ERP projects because a system lacks features. More often, problems appear because the software does not properly match the way the business operates. A system may look strong on paper, but still create friction if it does not support the realities of production, engineering, scheduling, inventory, and day-to-day decision-making.
The best ERP system is not automatically the largest platform or the most recognisable vendor. For manufacturers, the better fit is usually the system that supports how work actually moves through the business. A well-matched ERP can improve visibility and coordination, while a poorly matched one can leave teams relying on spreadsheets and workarounds just to get through the day.
When manufacturers focus on operational fit rather than reputation alone, they are usually in a much stronger position to choose a system that will support them long term.
