The overlooked importance of post go-live support in ERP implementations

Clients often think that their implementation project finishes when they are live in production. The reality is that the go-live marks the end of the initial implementation, but the beginning of a new project of continuous support and improvement of the ERP. In many ways, post go-live support can still make or break an ERP implementation and has enormous sway in whether the project overall is deemed a success.

Growing alongside the business

A company’s ERP is a living part of the business and operates in continuous evolution. It is shaped for and by employee usage, and as the needs of the business change, the ERP evolves alongside of it. It is therefore essential to have a framework in place to allow for the company and the ERP to evolve in tandem. Without a team dedicated to understanding new business requirements and putting in place new solutions, the ERP begins to act as a limiting fixture in the business, rather than a powerful tool for enhancing operations. 

An ERP without a post go-live strategy stays frozen in time, missing out on enhancements that are becoming more rapidly available. ERPs now more than ever are quickly evolving to offer cutting edge solutions so that businesses can remain competitive in the market. New and powerful features such as those which rest on large language models or agentic artificial intelligence, are important catalysts in the world of technology in 2026. 

There is, however, considerable effort required to understand and translate these features into something usable by the business and into material gains. This is where having a clear ERP strategy and evolution roadmap becomes so important. It allows companies to create a clear portrait of their growth while giving the business a chance to align themselves effectively with the integration partner and the other stakeholders of their IT ecosystem. Roadmaps and strategies themselves also need to evolve and be continuously improved upon, ensuring the company’s approach and efforts remain targeted and relevant.

A pillar of change management

Having a robust post go-live support plan is essential to ensuring a smooth transition from the legacy system to the new system. Although not an element of technical design or functionality, post go live support is often a primary indicator of overall user confidence in the new ERP. It is surprisingly common to observe user frustration after ERP go-lives, often created by mismatched expectations or unclear directives. Training sometimes gets forgotten by the time users need to be working in the ERP and the new methods become tedious and cloudy. It is therefore crucial to have a network of tools in place that allow for easy issue ticketing, prioritization, response, and resolution. Employees then recognize that their questions and concerns are heard and addressed, which facilitates change management and drives enthusiastic user adoption. Users see themselves within the ERP and recognize that the door is open for dialogue.

Beyond these concrete change management parameters, part of a company’s post go-live support strategy should also include an initiative to continue reframing the implementation and refocusing the business on why all these changes were put in place. It becomes the role of the business’s leaders and executives to rally their employees and remind them what the company was trying to achieve in changing their ERP solution, why they made these choices, and by what metrics success is to be measured. While change management is almost always discussed and addressed during the implementation, it becomes even more important after going live to keep the company on its course and continue fostering adoption and enthusiasm.

The first financial year

Going through a full financial cycle with the new ERP will often reveal missed use cases or untested scenarios. It is important that during this time, especially during year-end, a support strategy be in place to respond to issues as they come up that might prevent a proper year closure. The new year-end process will not be the same as the old process, initially creating delays and slowing down the final validations. Reports and dashboards that rely on coherent financial data become extremely important during this time.

Executive visibility

Even a highly successful implementation which arrives at its go-live on time and under budget can be perceived as a failure within the company if insufficient effort is dedicated to the post go-live phase. Small issues can quickly become widespread and debilitating for teams and departments if not addressed precisely and in a timely manner. Executives will seek to understand how their investment in the ERP is being received by employees and what kind of improvements it has created within the business. As within the context of change management, reframing and reminding leadership of their new goals, vision, and metrics for success is primordial in communicating and understanding the value creation of the new ERP. Executive visibility and leadership on post go-live usage, results, and return is key in measuring the success of both the project and the business.

Ultimately it is important to consider the true full cycle of a project, from its initial quotation to its operation, stabilization, appropriation, and enhancement. The post go-live project and the implementation project are two halves of a whole comprehensive IT enterprise transformation, the former often having as much, if not more, impact on the business and its future than the implementation itself.  Continuous improvement, persistent change management, and the need for clear ROI all represent opportunities for the business to either turn away and miss out on growth and improvement, or springboard into long-lasting success.
