Why system implementation support matters: getting more from your investment

28th October 2026 By Gareth Murphy
Choosing a new core system such as an Enterprise Resource Planning (ERP) or Customer Relationship Management (CRM) is a huge decision. The more mindful and mature businesses run a structured businesses run a structured selection process, weigh up how well each system fits their requirements, check the vendor is capable and culturally aligned, and make sure the numbers stack up. By the time a contract is signed, it can feel like the hard part is over. In reality, this is where many projects start to drift. Vendors will often say they have done this hundreds of times before and that their proposal includes everything needed to succeed. Some vendors do deliver good results working directly with their clients. Many others deliver, at best, a mediocre outcome Sadly in the worst case, the implementation can fail completely leading to large write offs, or vastly underused systems. Just ask Lidl and their €500 million write off of their failed 7 year SAP ERP project. It remains the case that 70-80% of IT projects fail to deliver on their original expectations. Here, our CEO, Gareth Murphy, explains what vendor proposals commonly leave out, and why independent system implementation support can make the difference between a project that limps over the line and one that transforms the business.

What vendor proposals often leave out

When a system implementation goes wrong, it rarely fails outright on day one. More often, the return on investment is smaller than the business case promised. The project runs late or over budget or goes live with a reduced scope that needs a second phase to finish the job. In the worst cases, the system never makes it over the line and creates serious risks for the business.

Much of this can be traced back to the fine print. One of our clients recently received a proposal to implement Microsoft Business Central. The project plan ran for around nine months, but the proposal included just nine days of project management in total. That is roughly one day a month to steer a major system change.

In our experience, vendor project management is mostly about managing the vendor’s own team. It does not usually cover bringing your stakeholders and process owners to the table for design workshops, or making sure the right people are available to test the solution properly before go-live.

Other gaps are common too:

Data migration – Proposals often state that data migration is the client’s responsibility. The vendor may provide a day of training on the upload tools, then leave you to extract, cleanse, complete and load your data, and check it has landed correctly.

Training – Many packages use a train-the-trainer model. A few of your people are trained, and it is then up to them to train tens or hundreds of colleagues. Accountability for making sure everyone is ready stays with you.

Client-side coordination – Someone needs to manage your people through requirements, design, testing and go-live. That work rarely appears in a vendor’s scope.

Change management – helping your team through the psychological uncertainty of change, hand holding them every step of the way So that they adopt the new system faster and more completely in order to realise greater benefits and ROI it’s almost certainly not in your vendor’s scope

The difference between a self-catering and a package holiday

Working directly with a vendor is a bit like booking a self-catering, self-planned holiday. It can be a great success, and it can be cost-effective. But the organising falls on you. You research and book the flights, arrange transfers to and from the airport, sort out the accommodation, plan the trips and excursions, do the food shop and cook every meal. 

Working with a trusted partner alongside your vendor is more like booking a premium, all-inclusive package holiday. You pack your bags and the rest is looked after, from the pick-up at your front door to the arrangements waiting for you when you land. 

At Fluid, we look after the things the system vendor does not. We manage the vendor on your behalf and manage your own people through the change, so your team can keep running the business. 

Why people, not technology, decide project success

The factors that most often separate a successful system implementation from a failed one are human, not technical. People need to understand why the change is happening, how their role and processes will change, and have the confidence to use the new system from day one. 

Prosci, the global leader in change management solutions, carries out long running benchmarking research which makes the point clearly. Of the projects with excellent change management, 88% met or exceeded their objectives, compared with only 13% of those with poor change management. That makes a project roughly seven times more likely to succeed. Even moving from poor to fair change management triples the likelihood of meeting objectives. The same research shows that excellent change management makes a project nearly five times more likely to stay on schedule and nearly 1.5 times more likely to stay on budget. 

At Fluid, our Head of Business Change, Sarah Toulson, leads our change approach using Prosci’s ADKAR model. It makes sure the people affected are Aware of the need for change, have the Desire to support it, gain the Knowledge and Ability to work in new ways, and receive the Reinforcement needed to make the change stick. You can read more about this in our blog on the benefits of change management. 

This approach was central to our work with ARC Inspirations on its move to Sage Intacct. Every team member was trained, informed and confident at go-live, with no negative feedback about preparedness. 

Why businesses hesitate to invest in implementation support

The most common barrier is cost. Done properly, professional project and change management can add around 40% on top of an implementation partner’s fees. When the focus is on buying and paying for technology, it is easy to see that wrapper of support as an optional extra that simply inflates the fees. 

Competitive tendering adds to the problem. Many vendors know their clients would benefit from change management and client-side support. But a vendor that includes it in their proposal can look expensive next to one that strips everything back to the basics. The tendering process rewards the leaner proposal, even when the vendor knows the client will need more. 

It is also worth noting that vendors often value this support too. On almost every project where we have worked alongside a vendor and a client, it is not just the client who tells us the project would not have gone as well without us. The vendor says it as well. 

The real question is what a suboptimal implementation would cost your business. What is the difference between achieving 50% of the benefits in your business case and getting close to 100%? What is the opportunity cost if it takes you a year longer than you planned for your team to adopt the new ways of working, and achieve the expected cost savings your new system will deliver? What is the cost, if the new system works so badly at go live that it permanently hits the confidence of the users that it can ever make their lives easier? A major system implementation is something most businesses only go through once a decade or so. The investment in getting it right is cost avoidance, risk reduction and benefit maximisation rolled into one. 

How Fluid supports your system implementation

We focus on business outcomes, not technology deliverables. Our goal is not simply to get the new system live. It is to help you achieve the return on investment and the benefits set out in your original business case. 

That means implementing the software correctly, but it also means: 

  • Engaging your people throughout, with a structured change management approach 
  • Making sure users are not only fully trained, measuring that they are capable and giving extra support where they need it 
  • Helping teams understand how their processes and ways of working will change and giving them adequate opportunities to become well practised in their new ways of working, prior to go live 
  • Doing the heavy lifting on data migration, from extraction and cleansing to making sure data is ready for upload 
  • Coordinating your people day to day, so the right stakeholders shape requirements, design and testing 
  • Supporting adoption for weeks or months after go-live, so new ways of working are embedded and benefits are realised. 

Because we are solution agnostic, we have no hidden agenda to push a particular product or vendor. We sit on your side of the table and hold the implementation partner to account.

FAQs

System implementation support is independent, client-side project and change management for a new system such as an ERP or CRM. It covers the work vendor proposals often leave with the client, including stakeholder coordination, data migration, testing, training and post go-live adoption. 

Most vendors include some project management, but it usually focuses on managing their own team and deliverables. It rarely covers managing your stakeholders, process owners and users through design, testing and adoption. 

In Fluid’s experience, professional project and change management typically adds 30% to 60% on top of the implementation partner’s costs. This should be weighed against the risk of overruns, reduced scope or a shortfall in the benefits set out in your business case. 

The biggest risks to a system implementation are usually human rather than technical. Prosci’s research shows that projects with excellent change management are around seven times more likely to meet their objectives than those with poor change management.
