Published: April 19, 2025

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

But beware: the choice of this miracle tool must be made for a solution adapted to ESNs, 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 a friendly bunch 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's defined as software that integrates various functionalities designed to manage all company processes.

It centralizes all data within a single space, and enables them to communicate with each other, in order to :

  • provide the various business functions with an overview of all 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
  • inventory management
  • HR management,
  • production management,
  • project management, etc.

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

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

Take account of your specific business needs

But are all the modules of a conventional ERP system beneficial to ESNs? For example, does inventory management make sense?

We recommend that you turn to a real business solution, which will be able to 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.

Consider the functionality required

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

In addition, consider the following parameters before making your choice:

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

Frequently asked questions: ERP & ESN, what we're always asking you

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 risk spending more time picking up the pieces than developing your business. And spoiler: it doesn't scale.

What's the minimum sales figure or number of employees you need?

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 sales, at around 1 million euros, a business ERP for ESN starts to become much more profitable than a mix of Excel + in-house tools. And your nights will be quieter 😴.

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

Yes, the best ERP for ESN are designed for this. They enable you to :

  • manage a variety of contracting modes;

  • track margins by mission;

  • 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, multi-client invoicing?

In fact, this is one of its greatest assets. No need to juggle e-mails, pivot tables and notepads: ERP automates reminders, invoices on account, down payments and even prorated 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, it will save them the eternal "I sent you my CRA, didn't you get it?". 😅

How do you get teams on board with a new system?

Two keys: get them involved early and show them the concrete benefits.

A well-deployed ERP eases their mental load: fewer manual tasks, greater clarity, fewer endless e-mails. 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. Now all you have to do is 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 get to grips with the software before you take the plunge!
