ERP selection

Comparing ERP systems: a practical decision framework

A feature list says little when every package ticks sales, inventory and reporting. The right choice is determined by process fit, the partner, total cost and how well the system works with your shop floor.

Compare more effectively

Why feature lists do not help

Almost every mature ERP can manage customers, products, sales orders, inventory and financial reporting. On a spreadsheet, every package therefore receives the same ticks. Differences only emerge in exceptions: a changed bill of materials, partial delivery, alternative route, machine data, complex approval or reporting across several companies.

A feature list also does not show how much configuration, how many add-ons and how much manual work are needed to make a function usable. “Manufacturing planning” can range from a simple list to finite-capacity scheduling. “WMS” can mean basic locations or advanced wave planning. The comparison must therefore start from real scenarios, volumes, error costs and the people who use the system.

Finally, comparisons often focus only on the package. The partner who analyses processes, migrates data, trains employees and manages custom work has at least as much influence on the result.

Decision criteria

The five questions that genuinely determine the choice

1. Where is the truth created?

Is the most important information entered in the office, scanned in a warehouse or produced by machines and measuring equipment?

2. Which exception costs the most?

It is not the ideal demo, but the expensive deviation that determines whether a system continues to work in practice.

3. How many systems do you want to manage?

A specialised system landscape can be powerful, but requires ownership of master data, interfaces and error handling.

4. How much change can the organisation absorb?

A technically better package fails when process decisions, training and internal capacity are underestimated.

5. Who remains responsible after go-live?

Determine which knowledge remains internal, which partner provides support and how upgrades, custom work and improvements are governed.

Competitor prices are not stated as fixed facts. Licences, editions, add-ons and partner costs change and must be verified during the selection process.

Total cost of ownership

Look at five years, not the first proposal

The first proposal includes licences and implementation, but the biggest differences emerge later. How many add-ons are required? Who maintains interfaces? What does a version upgrade cost? How many employees continue checking data between systems? How quickly can a process change be implemented without breaking custom work?

Calculate licences, implementation, internal project time, migration, training, integrations, support, upgrades and expected custom work over five years. Also include hidden operational costs: duplicate entry, error correction, waiting time and dependency on one employee who knows the workarounds.

A more expensive initial project can be cheaper when the system landscape becomes simpler. A low licence fee can prove expensive when several portals and integrations remain necessary. The pricing page shows how we separate the components.

Implementation capability

Why the partner can matter more than the package

An ERP contains possibilities, but the partner translates them into roles, data, exceptions and daily behaviour. The partner determines whether standard functionality is used sensibly, whether custom work remains manageable and whether employees can genuinely work before go-live.

For manufacturing and logistics, shop-floor knowledge is also required. Someone who only understands processes at screen level often misses where recording is physically impossible or illogical. Linky Business combines Odoo implementation with machine and device connectivity. This is not necessary for every company, but avoids an extra handover when the shop floor is part of the scope.

The quality of analysis and decision-making matters more than demo features.

When not

When Odoo is not the right choice

Odoo is a less suitable choice when a specialised industry system clearly fits the core process better and broad integration is not a priority. It is also a poor starting point when there is no internal project owner or time for process decisions: flexibility requires ownership and discipline.

If the current environment is stable, affordable and well integrated, optimisation may be more sensible than replacement. An honest selection process therefore keeps “no change” or “another package” open as serious outcomes.

Frequently asked questions

Practical answers in advance

No. Licence costs and flexibility can be favourable, but implementation, custom work and management determine the total cost. A poorly fitting Odoo configuration can become more expensive than a better-fitting alternative.

When the organisation mainly needs financial administration and straightforward trading, with little need for integrated manufacturing or logistics.

For organisations that value a traditional ERP model, a strong partner ecosystem and proven industry-specific solutions more than rapid adaptability.

Often it does, particularly when Microsoft 365, Power Platform and existing Dynamics expertise carry significant weight. The implementation and add-on structure must still be budgeted in full.

Consider product structure, planning, shop-floor recording, quality, traceability, integrations and the implementation partner's experience with your specific process.

The partner determines scope, process choices, data, training and management. The same package can therefore become either a clear platform or an expensive collection of exceptions.

From shortlist to decision

A selection process that produces comparable answers

Start with five to eight scenarios that together cover the core process and the most expensive exceptions. For each scenario, describe the starting situation, roles involved, desired outcome and available data. Ask every supplier to demonstrate the same scenarios and record which components are standard, configuration, add-ons or custom work.

Then request an implementation proposal with the same scope. Licences, migration, training, integrations, support and your internal project effort should be shown separately. A partner who asks difficult questions may provide a more realistic proposal than one who immediately says everything is possible during the demo.

Also assess the people who will deliver the project. Sales knowledge is not the same as implementation expertise. Ask who will guide process decisions, who will migrate data and who will provide support after go-live.

Evidence

Which demonstrations are genuinely informative

A standard sales order or dashboard mainly shows that the product exists. Ask for a change after release, a partial delivery, an inventory shortage, a manufacturing deviation, a return and a report that can be traced back to transactions. For shop-floor projects, the scenario should also include recording by an operator, scanner or device.

Ask the supplier to state what is not available directly. A credible answer includes boundaries, alternatives and management implications. If every question is answered “yes” without analysis, there is a significant risk that complexity will only become visible during the project.

Checks beyond the demo

What to ask about references and contracts

Ask for a reference with comparable processes, not merely the same industry. Discuss how scope changes, data, support and upgrades were handled. A satisfied client may still have a completely different level of complexity from your organisation.

Check in the contract who owns the configuration, custom work, documentation and exportable data. Record how rates change, which response times apply and what happens if the collaboration ends. Technical freedom has little value without practical transferability.

Do more than watch

Test an ERP system with your most difficult exception

A demonstration almost always runs smoothly when the supplier shows a standard process. The real differences become visible with an urgent order, partial delivery, reworked production, multiple units of measure or a journal entry that must be corrected afterwards. Bring three recognisable exceptions and ask the supplier to execute them step by step.

Do not focus only on the number of clicks. Ask who can adjust the configuration later, how changes are tested and which knowledge must remain with the partner or your own team. A solution that looks impressive today can be expensive in five years if every small change requires specialist custom work.

Also ask for references with process complexity similar to your organisation. A package that works well for trading does not necessarily offer the same depth for manufacturing, service or regulated quality.
