Choosing an ERP system is a significant business decision.

The right platform can connect departments, improve visibility, reduce manual work and provide a foundation for future growth.

The wrong one can introduce unnecessary complexity, require expensive customisation and leave employees working around the system instead of with it.

The challenge is that ERP platforms can look surprisingly similar during the selection process.

Most offer familiar functionality such as CRM, sales, finance, purchasing, inventory, projects or manufacturing. Feature lists alone therefore rarely tell you which system will work best for your organisation.

The better starting point is your business.

What processes need to improve?

Which information needs to be shared?

Where are the current bottlenecks?

Which functionality is genuinely essential?

And how will your requirements change as the organisation grows?

This guide provides a practical 12-point ERP selection checklist to help you evaluate ERP software based on the way your business actually operates.

ERP Selection Checklist at a Glance

Before choosing an ERP platform, evaluate these 12 areas:

	What to Evaluate	Key Question
1	Business requirements	What problems should the ERP solve?
2	Business processes	How well does the system support the way you work?
3	Required modules and functionality	Which capabilities do you actually need?
4	Integration requirements	Which existing systems must remain connected?
5	Flexibility and customisation	Can the system adapt where necessary?
6	Scalability	Can it support future growth and complexity?
7	User experience and adoption	Will employees actually be able to use it effectively?
8	Reporting and visibility	Can you access the information needed to make decisions?
9	Deployment and technology	Does the technical approach fit your organisation?
10	Implementation partner	Who will help translate your requirements into a working system?
11	Total cost of ownership	What will the system really cost over time?
12	Long-term fit	Will the platform still make sense in several years?

The purpose of this checklist isn't to find the ERP system with the most features.

It's to find the system that best matches your processes, requirements and ability to implement it successfully.

1. Start With Business Requirements, Not ERP Software

One of the easiest mistakes in ERP selection is starting with product demonstrations.

A vendor shows an impressive dashboard.

Another demonstrates automation.

A third presents hundreds of available features.

Soon the selection process becomes a comparison of software rather than an analysis of what the business actually needs.

Before evaluating ERP platforms, identify the problems the new system is expected to solve.

For example:

• Are employees entering the same information into multiple systems?
• Is data fragmented between departments?
• Does reporting require extensive manual preparation?
• Is inventory difficult to track accurately?
• Are sales, purchasing and operations poorly connected?
• Are existing systems limiting growth?
• Are important processes still dependent on spreadsheets?

These problems should become ERP requirements.

Instead of writing:

“We need an inventory module.”

define the actual requirement:

“Sales must be able to see current and expected stock availability before confirming a delivery date.”

The second statement is much more useful when evaluating ERP software.

It describes the business outcome the system needs to support rather than simply naming a feature.

If you're still determining whether your current systems have reached this point, our guide Why Do Businesses Need an ERP System? 10 Signs It May Be Time explains the most common warning signs.

2. Map Your Critical Business Processes

ERP doesn't simply store information.

Its real value comes from connecting processes that cross departments.

Consider a typical customer order:

CRM → Sales → Inventory → Purchasing or Manufacturing → Delivery → Invoicing → Accounting

Each step may involve different employees, responsibilities and information.

When evaluating ERP software, don't look only at whether each individual function exists.

Ask whether the complete process works.

For example:

A system may have excellent sales functionality and excellent inventory functionality.

But what happens when a salesperson confirms an order for an item that isn't currently available?

Does the system identify the shortage?

Can purchasing respond?

Can production see demand?

Does the expected availability become visible to sales?

Does the information eventually flow into delivery and invoicing?

ERP selection should therefore focus on end-to-end business scenarios, not isolated feature demonstrations.

A useful exercise is to identify several processes that are critical to your organisation and ask ERP providers to demonstrate those exact scenarios.

This reveals far more than a generic product presentation.

3. Identify the Modules You Actually Need

Modern ERP platforms can offer an enormous range of functionality.

That doesn't mean your organisation needs all of it.

A distributor might prioritise:

Sales + Inventory + Purchasing + Finance

A manufacturer may need:

Sales + Inventory + Purchasing + Manufacturing + Finance

A professional services company might focus on:

CRM + Sales + Projects + Time Tracking + Finance

The appropriate combination depends on how the organisation creates and delivers value.

Before evaluating platforms, separate functionality into three groups:

Essential

Capabilities required for the ERP implementation to succeed.

Important

Functionality that provides significant value but may not be required immediately.

Future

Capabilities the organisation may introduce as requirements evolve.

This prevents an ERP selection process from becoming a competition over which platform has the longest feature list.

It also helps distinguish genuine requirements from features that look impressive during a demonstration but may never be used.

If you need an overview of the functional areas typically available within ERP platforms, our guide ERP Modules Explained: Finance, CRM, Inventory, HR, Manufacturing and More provides a useful starting point.

4. Define Your Integration Requirements

Implementing ERP doesn't necessarily mean replacing every system your organisation already uses.

Some specialised applications may continue providing significant value.

Examples might include:

• e-commerce platforms,
• specialised production software,
• BIM or engineering applications,
• logistics systems,
• payment services,
• document management,
• marketing platforms,
• industry-specific applications.

The important question is whether these systems can exchange the required information with the ERP platform.

For each integration, define:

What information needs to move?

In which direction?

How frequently?

Which system should be the source of truth?

For example, simply stating:

“ERP must integrate with our webshop.”

isn't specific enough.

A useful requirement might instead be:

“Confirmed webshop orders must automatically create sales orders in ERP, while current product availability and order status must be synchronised back to the webshop.”

This level of detail makes it possible to evaluate whether an integration already exists, can be configured or will require custom development.

It also prevents integration requirements from being discovered late in the implementation, when they can become significantly more expensive to solve.

5. Evaluate Flexibility and Customisation

No ERP system will match every business process perfectly out of the box.

The question is how much adaptation your organisation actually needs.

There is an important difference between:

Configuration - adapting the system using standard options,

and:

Customisation - developing functionality that isn't available as part of the standard platform.

Configuration is usually easier to maintain.

Custom development can provide significant value when it supports a process that genuinely differentiates the business, but unnecessary customisation can increase cost, implementation complexity and future maintenance.

Before requesting a custom solution, ask:

Does this process really need to remain exactly as it is?

Sometimes the existing process exists simply because previous software imposed certain limitations.

An ERP implementation can be an opportunity to simplify the process rather than reproduce it.

At the same time, forcing every organisation into completely standard workflows isn't always realistic.

Some businesses have specialised operational requirements, industry-specific processes or integrations that genuinely require additional flexibility.

The right ERP platform should therefore provide an appropriate balance:

Standardise where possible. Adapt where it creates real business value.

When evaluating ERP software, consider how easily the platform can accommodate both.

6. Think About Scalability

The ERP system you choose today should also support the organisation you expect to become.

Growth can mean many things:

• More employees
• More customers
• More transactions
• More products
• Additional warehouses
• New business units
• New countries or markets
• More complex reporting
• Additional integrations
• New business processes

A system that works well for today's organisation may become restrictive if every significant change requires replacing software or building workarounds.

But scalability doesn't simply mean choosing the largest or most complex ERP platform available.

That can create the opposite problem.

A smaller organisation may end up paying for and managing complexity it doesn't need.

Instead, ask whether the platform provides a realistic path from your current requirements to your expected future requirements.

For example:

Can additional modules be introduced later?

Can new users and locations be added?

Can the system support multiple companies if required?

Can new integrations be introduced?

Can processes become more sophisticated without rebuilding the entire solution?

ERP should provide room to grow without requiring you to implement tomorrow's complexity today.

7. Consider User Experience and Adoption

An ERP system can have excellent functionality and still fail if employees don't use it properly.

ERP changes how people perform everyday tasks.

Salespeople may create quotations differently.

Warehouse employees may need to record movements directly in the system.

Project managers may track time or costs in a new way.

Finance may receive information automatically instead of collecting it manually.

This means usability isn't simply a cosmetic consideration.

It directly affects whether business processes are followed consistently and whether the information in the ERP system remains reliable.

During ERP evaluation, involve the people who will actually use the system.

Ask them to test realistic tasks rather than simply watch a presentation.

For example:

Can a salesperson create and confirm a typical order without unnecessary steps?

Can a warehouse employee quickly identify what needs to be picked and delivered?

Can a manager find the information required without asking someone to prepare another spreadsheet?

User feedback can reveal practical problems that aren't visible in a feature checklist.

Training is also important, but training shouldn't be used to compensate for unnecessarily complicated processes.

The easier the system is to understand and the more naturally it supports everyday work, the better the chances of successful adoption.

8. Evaluate Reporting and Visibility

One of the reasons businesses move towards ERP is to gain better visibility across operations.

But simply having all the data in one system doesn't automatically mean that useful information will be easy to access.

Before choosing an ERP platform, identify the questions management and operational teams need to answer.

For example:

• What is our current sales pipeline?
• Which orders are delayed?
• What stock is available or expected?
• Which products are most profitable?
• What purchases are outstanding?
• Which projects are exceeding their budgets?
• What is our current cash position?
• How is performance changing over time?

Then determine whether the ERP system can answer these questions without requiring extensive manual preparation.

Look at:

• Standard reports
• Dashboards
• Filters and drill-down capabilities
• KPIs
• Custom reporting options
• Data export
• Analytics and business intelligence integrations

The goal isn't necessarily to eliminate Excel or external analytics tools.

Spreadsheets can remain extremely useful for ad-hoc analysis and specialised modelling.

The important distinction is that reporting shouldn't depend on employees manually reconstructing basic operational information from multiple disconnected sources.

If this is already a problem in your organisation, our guide ERP vs Excel: When Spreadsheets Stop Being Enough explains where spreadsheets remain useful and where an integrated system becomes the better foundation.

9. Choose the Right Deployment and Technology Approach

ERP systems can be deployed in different ways.

Depending on the platform, organisations may use:

• Vendor-managed cloud services
• Public or private cloud infrastructure
• On-premise infrastructure
• Hybrid environments

There is no single deployment model that is automatically right for every business.

The appropriate approach depends on factors such as:

• Internal IT resources
• Security requirements
• Existing infrastructure
• Integration requirements
• Regulatory requirements
• Required level of control
• Maintenance responsibilities
• Availability and performance requirements

It's also important to look beyond the simple label “cloud ERP”.

Two ERP systems described as cloud solutions may differ significantly in how they're hosted, updated, customised and managed.

Ask practical questions:

Who manages the infrastructure?

Who performs updates?

How are backups handled?

What happens if custom functionality is introduced?

How is the system monitored?

How easily can data be accessed or migrated if requirements change?

Technology should support the business requirements defined earlier in the selection process rather than become the starting point for the decision.

10. Evaluate the Implementation Partner, Not Just the Software

Choosing ERP software is only part of the decision.

Someone still needs to turn that software into a system that supports your organisation.

That usually involves:

• Process analysis
• Solution design
• Configuration
• Data migration
• Integrations
• Custom development where required
• Testing
• Training
• Deployment
• Ongoing support

For this reason, the quality of the implementation can be just as important as the platform itself.

A capable implementation partner shouldn't simply ask which modules you want.

They should understand why you need them and how information needs to move through the organisation.

During the selection process, consider questions such as:

• Does the partner understand our business processes?
• Have they identified risks or challenged unclear requirements?
• Can they explain what should remain standard and what genuinely requires customisation?
• Do they understand the integrations we need?
• Is the proposed implementation approach clear?
• Who will actually work on the project?
• How will changes in scope be handled?
• What happens after go-live?

Be cautious if an ERP project is presented primarily as a software installation.

Successful ERP implementation is a combination of technology, processes and people.

11. Calculate the Total Cost of Ownership

Licence price is one of the easiest ERP costs to compare.

It is also only one part of the total investment.

Depending on the platform and implementation, costs may include:

• Software licences or subscriptions
• Hosting or infrastructure
• Implementation
• Configuration
• Data migration
• Integrations
• Custom development
• Training
• Support
• Maintenance
• Upgrades
• Additional modules
• Internal project resources

A platform with a low subscription price can become expensive if extensive custom development is required.

A more expensive platform may include functionality that would otherwise need to be developed separately.

Implementation approach can also make a substantial difference.

This is why ERP systems should be compared using total cost of ownership, not simply the price shown on a software website.

Ask vendors and implementation partners to clearly separate:

Initial implementation costs

from:

Recurring costs

and:

Potential future costs.

You should also understand which assumptions the estimate is based on.

A low estimate built around an incomplete understanding of your requirements isn't necessarily a better offer.

12. Evaluate Long-Term Fit

ERP isn't usually a short-term investment.

Once the system supports sales, inventory, purchasing, finance, projects, manufacturing or other critical processes, replacing it can become a significant undertaking.

The final question should therefore be:

Will this ERP platform still make sense for us several years from now?

Consider:

• The platform's development and product direction
• Availability of implementation and technical expertise
• Integration possibilities
• Ability to add functionality
• Upgrade path
• Data accessibility
• Vendor and partner ecosystem
• Support options
• Expected future business requirements

No organisation can predict every future requirement.

The goal isn't to find a system that solves hypothetical problems ten years in advance.

It's to avoid selecting a platform that already appears restrictive based on the direction your organisation is moving.

A good ERP choice should solve today's problems while leaving enough flexibility for tomorrow's opportunities.

Don't Compare ERP Systems With a Feature Checklist Alone

Once requirements have been defined, businesses often create a spreadsheet containing dozens or even hundreds of ERP features.

Each vendor receives a score:

Yes.

No.

Partial.

Custom development required.

This can be useful, but it also has limitations.

Two ERP systems may both receive a “Yes” for inventory management while supporting the actual process in completely different ways.

Similarly, a platform may technically support a required feature but require a complicated workflow that employees will struggle to use.

Feature comparison should therefore be combined with scenario-based evaluation.

Instead of asking only:

“Does the system support purchasing?”

ask the vendor to demonstrate:

“A customer order creates demand for an item we don't have in stock. Show us how the system identifies the requirement, creates or suggests a purchase, receives the goods and updates the customer order.”

Real business scenarios reveal how modules, workflows and information actually work together.

And that's ultimately what ERP is supposed to do.

A Practical ERP Evaluation Scorecard

Once you've narrowed the selection to a few realistic options, a simple weighted scorecard can make the comparison more objective.

For example:

Evaluation Area	Example Weight
Business process fit	20%
Required functionality	15%
Integration capabilities	10%
Flexibility	10%
Scalability	10%
User experience	10%
Reporting & analytics	5%
Technology & deployment	5%
Implementation partner	10%
Total cost of ownership	5%

The percentages shouldn't be treated as universal recommendations.

A manufacturer may assign more weight to process fit and production functionality.

A business with many specialised applications may give integrations greater importance.

An organisation with limited internal IT resources may place greater emphasis on implementation and ongoing support.

The purpose of weighting is to force an important conversation:

What actually matters most to our organisation?

Only then should individual ERP platforms be scored.

This prevents a less important feature from influencing the decision as much as a requirement that is critical to the business.

How to Shortlist ERP Systems

The ERP market includes many platforms, and evaluating all of them in detail would be inefficient.

A better approach is to gradually narrow the field.

Start by eliminating solutions that clearly don't meet fundamental requirements.

For example, a platform may be unsuitable because it:

• doesn't support a critical business process,
• cannot provide a required integration,
• doesn't support your deployment requirements,
• lacks necessary localisation,
• cannot realistically scale with the organisation,
• falls significantly outside the available budget.

Once these basic criteria have been applied, create a shortlist of ERP platforms worth evaluating in greater detail.

At this stage, demonstrations should focus on your own business scenarios rather than generic product features.

Provide vendors or implementation partners with the same scenarios and ask them to demonstrate how their proposed solution would handle them.

This makes comparisons much more meaningful.

You're no longer comparing presentations.

You're comparing how different ERP solutions would support the same business.

Questions to Ask ERP Vendors and Implementation Partners

By the time you reach detailed evaluation, you should be asking much more than:

“Does your ERP have this feature?”

Useful questions include:

• Which of our requirements are supported by standard functionality?
• Which require configuration?
• Which require custom development?
• How would our most important end-to-end processes work?
• Which integrations already exist?
• Which integrations would need to be developed?
• How will existing data be migrated?
• What responsibilities will our internal team have?
• How will users be trained?
• How are updates and upgrades handled?
• What happens to custom functionality during upgrades?
• What support is available after go-live?
• Which costs are included in the proposal?
• Which potential costs are not included?
• What assumptions is the implementation estimate based on?
• How will additional requirements or changes in scope be handled?

The answers matter.

But so does how the questions are answered.

An implementation partner who asks detailed questions about your processes, challenges assumptions and identifies potential risks may provide more value than one who simply confirms that every requirement is possible.

ERP selection is not only about finding software that can do what you ask.

It's also about finding an implementation approach that helps you determine what you actually need.

Common ERP Selection Mistakes to Avoid

Even a structured selection process can go wrong if the decision is based on the wrong criteria.

Choosing the Most Familiar Brand

A well-known name can provide reassurance, but brand recognition doesn't automatically mean the platform is the best fit for your organisation.

ERP is a category of business software with many different platforms and providers.

As we explain in ERP vs SAP: Is SAP an ERP System?, businesses should evaluate individual ERP solutions against their requirements rather than treating one vendor as synonymous with ERP.

Choosing the System With the Most Features

More functionality isn't automatically better.

Features create value only when they support processes your organisation actually needs.

Unused functionality can instead introduce additional complexity.

Focusing Only on Licence Price

A lower licence or subscription price doesn't necessarily mean a lower total cost.

Implementation, customisation, integrations, support and internal resources can have a much greater impact on the overall investment.

Recreating Every Existing Process

“This is how we've always done it” isn't necessarily a business requirement.

ERP implementation is an opportunity to examine whether existing processes still make sense.

Preserve processes that create value.

Improve those that don't.

Ignoring Users Until the End

Employees who perform the processes every day often understand practical requirements that aren't visible at management level.

Involving key users early can improve both the quality of the selection and eventual adoption.

Underestimating Implementation

ERP isn't simply another software purchase.

Even an excellent platform requires clear requirements, good data, realistic planning, testing, training and organisational involvement.

Selecting the software is only the beginning.

Frequently Asked Questions

How do you choose the right ERP software?

Start by defining your business requirements and critical processes before comparing individual ERP platforms.

Then evaluate potential solutions based on factors such as functionality, integration, flexibility, scalability, usability, reporting, deployment, implementation support and total cost of ownership.

The right ERP is the one that best fits your organisation's requirements rather than the one with the longest feature list.

What are the most important ERP selection criteria?

The exact priorities depend on the organisation, but common criteria include:

• Business process fit
• Required functionality
• Integration capabilities
• Flexibility
• Scalability
• User experience
• Reporting
• Technology and deployment
• Implementation capabilities
• Total cost of ownership
• Long-term fit

These criteria should be weighted according to their importance to your business.

How many ERP systems should you evaluate?

There is no fixed number, but evaluating too many systems in depth can make the process unnecessarily complex.

A broad initial market review can be used to eliminate clearly unsuitable options.

A smaller shortlist can then be evaluated using detailed requirements, demonstrations and real business scenarios.

The objective is to compare a manageable number of realistic candidates rather than every ERP platform available.

Should you choose ERP software or an implementation partner first?

The two decisions are often closely connected.

Some implementation partners specialise in particular ERP platforms, while the quality of implementation can significantly affect the success of the selected software.

For this reason, businesses should evaluate both the ERP platform and the people who will implement it.

A technically suitable platform with a poor implementation approach can still lead to a poor result.

Should ERP be customised to match existing business processes?

Not automatically.

Standard ERP functionality should be used where it supports the business effectively.

Customisation makes sense when it addresses a genuine requirement that cannot reasonably be solved through standard functionality or process improvement.

The objective shouldn't be to reproduce every existing process exactly as it works today.

How important is scalability when choosing ERP?

Scalability is important, but it should be considered realistically.

The ERP should support expected growth in areas such as users, transactions, locations, modules and business complexity.

However, choosing an unnecessarily complex system purely because it might be needed one day can create additional cost and implementation difficulty today.

What should you ask for in an ERP demonstration?

Avoid relying entirely on a standard vendor presentation.

Provide several real business scenarios and ask the vendor or implementation partner to demonstrate them from beginning to end.

For example:ž

A customer orders a product that isn't currently available. Show us what happens from sales order through procurement, delivery and invoicing.

This reveals how the ERP actually supports your processes and how different modules work together.

Conclusion

Choosing ERP software isn't primarily a technology decision.

It's a business decision supported by technology.

The process should begin with understanding how your organisation works today, where the problems are and what needs to improve.

Only then should individual ERP platforms be compared.

A structured selection process should evaluate:

Business requirements → Processes → Functionality → Integrations → Flexibility → Scalability → Users → Reporting → Technology → Implementation → Cost → Long-term fit

No ERP platform will be perfect in every category.

And the system with the most functionality isn't necessarily the right one.

The goal is to find the best overall fit between the software, your business processes and the organisation that will use it.

Taking the time to define that fit before implementation can prevent expensive compromises later.

What Comes Next?

Choosing the right ERP platform is only one part of a successful ERP project.

Once the decision has been made, the focus shifts from which system to choose to how to implement it successfully.

An ERP implementation affects processes, data, integrations and the people who use the system every day. A good implementation therefore requires much more than installing and configuring software.

In our next guide, ERP Implementation Process: 7 Steps From Planning to Go-Live, we'll walk through the ERP implementation lifecycle from defining the project and preparing data to testing, training and launching the new system.

Choosing an ERP System?

A successful ERP project starts before implementation.

Understanding your processes, defining the right requirements and evaluating how different solutions support them can significantly reduce uncertainty later in the project.

At Gecko IT, we help organisations analyse their business processes, define ERP requirements and implement integrated solutions based on Odoo, including custom functionality and integrations where standard ERP capabilities aren't enough.

If you're evaluating ERP platforms and want to determine whether Odoo fits your requirements, we can help you assess both the possibilities and the practical implications before implementation begins.
