Your ESN needs an ERP too! Discover the 11 market champions

Published: 19 April 2025

Digital Service Companies, like any other business, need to structure and digitalise their activities to meet today's challenges and compete effectively. That's why the need for the power of a dedicated business ERP quickly becomes apparent.

But beware: when it comes to choosing this miracle tool, you need to choose a solution that is suited to NSEs, since they operate in the form of assignments to which they assign consultants. And not all management software on the market guarantees such alignment!

Fortunately, there are a number of ERP solutions for ESNs. As we're friendly people here at Appvizer, we've put together a selection of the 11 best.

Definition and benefits of an ERP for ESN

First of all, what exactly is an ERP?

An acronym for Enterprise Resources Planning, it is defined as software that integrates various functions designed to manage all the company's processes.

It centralises all the data in a single space and enables them to communicate with each other, so as to :

  • provide the various business lines with an overview of their activities ;
  • support them in managing their missions.

To achieve this, ERP systems are made up of a multitude of modules. Although they differ from one solution to another, they generally include :

  • CRM
  • accounting and financial management
  • stock management
  • HR management
  • production management
  • project management, etc.

Of course, these ERPs are modular, so that each organisation can build a solution in line with its own reality.

👍 The automation and coordination of workflows enabled by these solutions means real productivity gains. At the same time, the automation and unification of information reduces the risk of errors. Ultimately, companies save money.

How do you choose an ERP for your ESN?

Take account of your specific business needs

But are all the modules in a traditional ERP system beneficial to ESNs? For example, does stock management make sense?

We recommend that you opt for a real business solution, one that can accommodate your specific needs by offering dedicated functionalities such as :

  • staffing
  • consultant management
  • business management and tracking
  • declaration and monitoring of working hours,
  • management of different types of invoicing (by time spent, for example),
  • monitoring KPIs and profitability, etc.

Study the functionality required

However, even if you narrow down your choice to specialist software, each also has its own functional coverage. So it's a good idea to draw up an exhaustive list of your requirements beforehand. For example, will a CRM be useful if you want to keep yours?

In addition to this, you should evaluate the following parameters before making your choice:

  • ergonomics and ease/quickness of deployment,
  • cost and potential return on investment,
  • integration with your current tools,
  • modularity and scalability,
  • the hosting mode (on-premise or SaaS?),
  • the degree of support provided by the publisher and the quality of its customer service,
  • data security.

Frequently asked questions: ERP & ESN, what we ask you all the time

Is an ERP really useful for a small ESN?

Yes. Even with a small team, the challenges of project management, invoicing and resource management are already very real.

Without a structuring tool, you run the risk of spending more time picking up the pieces than developing your business. And spoiler: it doesn't scale.

At what turnover or number of employees does it become essential?

As soon as you have more than 10 employees or your projects are moving at a good pace, the need becomes obvious.

In terms of turnover, at around €1 million, a business ERP for ESNs starts to become much more profitable than a mix of Excel and in-house tools. And your nights will be quieter 😴.

Is it possible to track fixed-price, project management and TMA projects in a single tool?

Yes, the best ERP for ESNs are designed for this. They allow you to :

  • manage a variety of contracting methods;

  • monitor margins by assignment

  • anticipate future workloads for each scope.

A good ERP speaks the language of your project managers and your management controllers.

Can ERP simplify my monthly and multi-client invoicing?

That's one of its greatest assets. There's no need to juggle emails, spreadsheets and notepads: ERP automates reminders, invoices on account, down payments and even pro-rated invoicing.

Will my consultants have to change their habits?

A little, but don't panic.

Good ERP systems focus on a simple user experience, with interfaces designed for non-accountants. You don't need to be a CFO to enter your time or validate an assignment.

What's more, they won't have to deal with the eternal "I sent you my CRA, didn't you get it? 😅

How do you get teams to buy into a new system?

There are two keys: get them involved early on and show them the tangible benefits.

A well-deployed ERP reduces their mental workload: fewer manual tasks, greater clarity, fewer endless emails. And if, in addition, you appoint one or two internal champions, it can quickly become a collective reflex.

In conclusion

You now know the best ERP ESNs on the market. All that remains is to find the one that will boost your company's performance tenfold.

We also recommend that you take advantage of the free trials offered by most publishers. They'll give you a chance to immerse yourself in the software before you take the plunge for good!
