Who designs your ERP, who implements it, and what that means for your project

ERP vendor or integrator: comparing provider models for a manufacturing SME

When you choose an ERP, you also choose a provider, and its model shapes the entire project that follows.

Some providers develop their own software, others implement software from a third-party vendor, and others do both. This model determines who configures your solution, who develops your specific requirements, who responds when an issue arises and who evolves the software over time.

Each model has its strengths depending on the context. This guide helps you identify the one that fits your organization, your business requirements and the relationship you expect from your provider.

4 provider models to tell apart: vendor, integrator, vendor-integrator and reseller
7 criteria for comparing a vendor-integrator and an independent integrator
5 questions to ask a provider before signing

In one sentence: an ERP vendor designs and develops the software, while an ERP integrator installs it, configures it and supports the company through deployment; a vendor-integrator plays both roles, which reduces the number of contacts but limits the choice to its own solution.

1. What is the difference between an ERP vendor and an ERP integrator?

An ERP vendor is the company that designs, develops and evolves the software. An ERP integrator is the provider that implements it for the customer: requirements analysis, configuration, data migration, interfaces, training and support. Depending on the provider, these two roles are held by two separate companies or by a single one.

The four ERP provider models

The vendor
It designs and develops the software, defines its roadmap and releases updates. A vendor that does not implement its own solution relies on a network of partners to roll it out to customers.
The integrator
It implements software developed by a third-party vendor for its customers. It masters configuration and project methodology, and can carry out additional developments, but changes to the core of the software remain the vendor's decision.
The vendor-integrator
It develops its own software and implements it for its customers itself. The consultants who configure the solution work with the team that develops it, within the same company.
The reseller
It sells licenses or subscriptions. The support offered varies from one reseller to another, from a simple sale to a full service: a point to check case by case.

Not to be confused with an independent ERP consultant: this consultant (known in France as AMO, assistance à maîtrise d'ouvrage) helps you express your requirements, write the specifications and compare offers, without implementing the software. The consultant advises; the final decision rests with the company's management.

2. Vendor-integrator or independent integrator: the comparison

The difference lies mainly in how information flows. With a vendor-integrator, the person who configures your ERP works in the same company as the team that develops it. With an independent integrator, the provider acts as the link between you and an external vendor, but can offer you several software products.

The 7 comparison criteria

CriterionVendor-integratorIndependent integrator
Software choiceLimited to its own solutionOne or more solutions, depending on its partnerships
ContactsA single company, from sale to supportThe integrator day to day, the vendor in the background
Custom developmentsCarried out by the team that develops the softwareCarried out by the integrator around the software, with the core remaining under the vendor's control
Software evolutionCustomer feedback goes directly to the development teamPassed on to the vendor by the integrator, which does not control the timing
Issue after go-liveA single party responsible for diagnosisDiagnosis shared between integrator and vendor, depending on the source of the problem
Changing providerChanging provider generally means changing softwarePossible to change integrator while keeping the same software
Version upgradesPrepared and carried out by the team that develops the softwareReleased by the vendor, then applied for the customer by the integrator

How to read this table: the same row can be an advantage or a drawback depending on your priorities. A company that wants to compare several software products will value choice; a company with highly specific processes will value proximity to the development team.

In both cases, check the scope covered: an integrator can implement several software products, and a vendor-integrator can also integrate third-party solutions, in business intelligence or accounting for example. Ask for the list of solutions implemented and the partnerships in place.

The same applies to industry expertise and proximity: they depend on each provider, whatever its model. Ask for references in your industry and where the teams that will work with you are located.

3. When is an independent integrator the right choice?

An independent integrator makes sense when you want to compare several software products with a single contact, when you have already chosen an ERP distributed through a partner network, or when you want to keep the option of changing provider without changing software.

Four situations where an independent integrator has the edge

You are still choosing the software
An integrator partnered with several vendors can present different solutions and help you compare them. Ask about its commercial ties with each one: they may influence its recommendation.
The software you are considering is distributed by partners
Many vendors, especially the largest ones, rely on a network of integrators to implement their solution. The choice then focuses mainly on the partner: its knowledge of your industry, its references and its proximity.
You want to be able to change provider
With software distributed by several integrators, you can change partner while keeping your ERP, your configuration and your data, subject to the terms of your contracts.
You want to consult several providers for the same software
When a vendor relies on a partner network, you can ask several integrators to quote for implementing the same software, and compare their methodology, their team and their terms.

4. When does a vendor-integrator make the difference?

A vendor-integrator has the edge when your business requires custom developments, when you expect high responsiveness on software changes, or when you want a single party responsible from sale to support. The trade-off is that its offer is limited to its own solution.

Five situations where a vendor-integrator has the edge

Your business processes go beyond the standard
Engineer-to-order manufacturing, complex bills of materials, regulatory traceability: when your requirements call for custom developments, entrusting them to the team that develops the software makes it easier to maintain them through updates.
You expect regular software improvements
Your requests go directly to the development team, with no external channel. This makes it easier for them to be taken into account in future versions of the software.
You want a single party responsible
When an issue arises, the question of whether it stems from the configuration or from the software is settled within the same company, without back-and-forth between two providers.
You are looking for a long-term relationship
The team that supports you at go-live knows the product in depth, and can remain your point of contact for as long as you use the software.
You want to limit information loss
Commitments made during the sales phase are passed on internally to the project team, which limits gaps between what was presented and what is delivered.

Points to check with a vendor-integrator: its financial strength and track record, since both the software and the support depend on the same provider, its references in your industry, and the terms for retrieving your data at the end of the contract.

5. Proges Plus, an example of both models

Proges Plus works with both models. The company is the vendor-integrator of Synoptic ERP, which it develops and implements itself for manufacturing SMEs from its offices in Lille, Lyon and Nantes. It also acts as an integrator of third-party solutions: as a Sage Competence Center (Centre de compétence Sage), it implements this vendor's business management solutions, and it is a MyReport partner for business intelligence.

This dual position gives a concrete view of what each model brings: full control of the software with Synoptic ERP, the backing of partner vendors with Sage and MyReport. To see how a project unfolds, take a look at the Synoptic ERP deployment methodology.

6. Questions to ask your future provider

These five questions quickly reveal which model a provider follows and how it divides responsibilities. Ask them to every provider you consult, and compare the answers.

Five questions to find out who you are dealing with

Who develops the software you are offering me?
Good answer: the name of the vendor and the nature of the relationship with it (vendor itself, certified partner, reseller).
Red flag: a vague answer, or software presented as "in-house" with no further detail.
If I need a specific feature, who develops it and who maintains it through updates?
Good answer: a clear process, with an identified party responsible for compatibility with future versions.
Red flag: "we'll see when the time comes", or a development excluded from the maintenance contract.
Who is responsible if an issue appears after go-live?
Good answer: a single support contact who handles the diagnosis, whatever the source of the problem.
Red flag: being passed back and forth between integrator and vendor depending on the type of incident.
Will the consultants who implement my ERP be the ones who support me afterwards?
Good answer: an identified team, a named project manager and continuity planned after go-live.
Red flag: different people at each phase, with no organized handover.
Do you have customers comparable to my company that I can contact?
Good answer: references in your industry and of similar size, reachable directly.
Red flag: only anonymous references, or references far removed from your business.

FAQ: ERP vendor or integrator

What is an ERP integrator?

An ERP integrator is a provider that implements business management software in a company: requirements analysis, configuration, data migration, interfaces with other tools, user training and support after go-live. It can implement software from a third-party vendor or, if it is also a vendor, its own solution.

What is an ERP software vendor?

An ERP software vendor is the company that designs, develops and evolves the software. It defines the roadmap and releases updates. Some vendors implement their software themselves, others rely on a network of partner integrators.

What is the difference between a vendor-integrator and an integrator?

A vendor-integrator develops and implements its own software: a single company manages both the product and the project. An integrator implements another vendor's software: it can offer several solutions, but changes to the software remain the vendor's decision.

Is it better to work with a vendor or an integrator for a manufacturing SME?

For a manufacturing SME, a vendor-integrator is a relevant choice in many cases. Manufacturing processes regularly require adaptations, and entrusting the software and its implementation to the same company makes it easier to take them into account, maintain them through updates and support them. An independent integrator remains a good option for comparing several software products or for keeping the possibility of changing provider without changing ERP.

Can you change integrator without changing ERP?

Yes, when the software is distributed by several integrators. The company then keeps its ERP, its configuration and its data, subject to the terms of its license and maintenance contracts. With a vendor-integrator, changing provider generally means changing software.

Can an integrator develop custom features?

An integrator can carry out developments around the software, such as reports, interfaces or add-on modules, within the possibilities opened up by the vendor. The core of the software, however, remains under the control of the vendor, the only party able to modify it. Before signing, check who maintains these developments through software updates.

Why choose a vendor-integrator for your ERP?

A vendor-integrator brings together, within the same company, the team that develops the software and the team that implements it. Specific requirements are handled by people who master the software, change requests reach the developers without intermediaries, and a single party responds when an issue arises. The trade-off is that the choice is limited to this vendor's solution.

In conclusion: choosing a provider model suited to your project

Vendor, integrator or vendor-integrator: the right choice depends on your business requirements, on whether you want to compare several software products and on the relationship you expect over time. An ERP supports a company for many years, and the provider's model deserves the same attention as the features.

Ask each provider you consult the five questions in this guide: their answers quickly show who does what, and who will be responsible for what.
