What is an ERP solution?

An Enterprise Resource Planning (ERP) solution is a central data repository that connects every department in an organization and allows all the company’s information to be accessed—anytime, anywhere.

Modern ERP solutions are also powerful, intelligent platforms that can automate manual tasks, consolidate all inventory, product, manufacturing, distribution, and project-related information. By breaking down data silos, an ERP solution sets businesses up for success in the digital economy. However, before your team can enjoy this single source of truth, your business must complete the ERP implementation life cycle.

What is ERP Implementation?

An ERP implementation is the step-by-step process of installing your chosen ERP system software, moving your business data over to the new system, configuring your custom workflows, and training your employees.

That may sound like a lot, but these components of an ERP system implementation do not happen all at once. They are accomplished in a logically progressing way across the entire implementation life cycle. This structured approach helps ensure seamless compliance, minimizes disruptions, and maximizes your return on investment.

What Are the Eight Steps of the ERP Implementation Process?

As with any large project, you must approach an ERP implementation by carefully progressing through each project phase, one step at a time. Every ERP deployment life cycle is made up of eight standard stages, all of which are critical to the project success.

The timeframe for completing these stages differs from company to company. For perspective, most ERP implementations are completed from planning to a fully operational system in six months to one year. Each step should be fully completed before moving on to the next, which ensures that all parts of the process are built on firm foundations.

Step 1: Planning and Organization

The planning and organization phase establishes the foundation for your entire project. This involves securing executive buy-in, assembling your ERP implementation team, and choosing your deployment model.

Getting leadership and IT buy-in for the project is your first priority. Support from your executive team and IT department is critical because the rest of the organization looks to them for leadership and security. Here are some important steps to attaining leadership support:

- Explain why a modern cloud ERP solution is important: Most executives today are fully aware of the need for a digital transformation strategy. To remain competitive, businesses must automate important business management processes to increase efficiency, scalability, and profitability. You must clearly communicate what a modern ERP solution can do: put every department on the same page with a single source of truth, provide real-time data for better decision making, and allow for seamless integration with necessary third-party applications.
- Highlight the ROI: Justifying a large expenditure requires estimating the cost of the investment, from licensing and implementing it to training users. The total cost is then weighed against the benefits of a new system. The benefits of cloud ERP solutions generally include reduced operating expenses, automated regulatory compliance, improved customer satisfaction, and increased data analysis for better decision making.
- Keep the leadership team in the loop: A designated champion from the leadership team should meet with the organization regularly throughout the ERP implementation. They will not only be prepared for the process but also help resolve any challenges that arise.

Once there is support from leadership and the process of implementation starts developing, it is important to have the whole company involved in the process. Here is what you can do:

1. - Communicate the ERP rollout plan right away: The benefits of a cloud-based ERP solution may be unclear to employees who have been using a legacy system for years. Giving employees advance notice that a new business management system is in the works gives them time to ask questions and adjust.
  - Communicate the features and benefits clearly: Communicating the benefits before and during the ERP implementation will help ease the transition. Cloud ERP solutions are designed to be learned intuitively, and the benefits include increased efficiency, better compliance reporting, and scalability.
  - Communicate leadership support:Attaining organizational buy-in without pushback is always the goal. Reinforcing the fact that the executive team fully supports this major investment can facilitate faster acceptance.
Next, you will assemble your ERP implementation team. These employees should be drawn from different departments, and each will be given a specific role to ensure cross-departmental synchronization. Finally, you must choose your deployment option, whether it is a cloud-based SaaS, private-cloud, or hybrid environment.

ERP Implementation Steps

Step 2: ERP System Selection

ERP system selection is the process of defining your business requirements, identifying functional gaps in your current software, and choosing the platform that best aligns with your goals.

Defining Requirements

Defining cloud ERP solution requirements involves documenting current business processes. You and your team will need to determine which processes you can improve and how you want your new Acumatica ERP solution to function. There are four general areas within which your requirements fall:

Essential: Features or functions that are mandatory for the company to operate, such as automated tax compliance.
Desirable: Functions that would significantly enhance the usefulness of the new system.
Not an immediate need: Functions that are not required at this time but will be necessary soon, depending on the company’s growth and advances in technology.
Nice to have: Non-essential functions that would make work easier.

You and your team will then create a list, starting with essential functionality and ending with additional functionalities that are affordable and fit your timeline. By the time you’re done, you should have a list of features and functions you expect to have when the project is completed.

System Selection

Now that you have established your requirements, it is time to execute the ERP software selection process.

The decision-making process begins by determining what pain points exist within your tech stack, your available budget, and how you want to host the ERP solution. From there, evaluate your options based on scalability, usability, functionality, and security features.

Step 3: Installation

Installation involves setting up the software infrastructure for your new ERP solution. If you chose a SaaS deployment, installation is nearly instantaneous; if you chose on-premises or hybrid, it involves physical hardware setup.

If you chose to deploy your new ERP solution as a SaaS instance, you will have no software installation requirements and little to no installation lead time. If you chose a private-cloud or hybrid model, there will be a window of days to weeks during which hardware and software will be delivered and installed on your premises.

Step 4: Data Migration

Data migration is the process of filtering, cleaning, and transferring your legacy business data into the new ERP solution. Clean data is vital for accurate analytics and reporting.

Once your chosen ERP solution has been installed, company data must be filtered to remove any incorrect or redundant data. This includes basic records like customer, vendor, and item master files, as well as general ledger charts of accounts. Just before going live, active transactional data will be converted and moved into the new software.

Step 5: Training

Training empowers your staff to confidently use the new ERP solution. Effective training is the key to high user adoption and immediate productivity gains.

Employees you designate as subject matter experts should receive specialized training during this part of the ERP implementation process. This allows them to teach others and serve as internal resources for questions. All other users should be taught how to perform their specific roles within the new system.

Step 6: Testing and Validation

Testing and validation ensure the ERP solution works exactly as expected before launch. This phase prevents operational disruptions and guarantees data integrity.

This step involves creating and applying a detailed testing plan to measure user acceptance. You should also employ your IT resources to validate whether the new software is functioning properly. They must ensure that all company data migrated in step four is complete and accurate.

Step 7: Go Live

The go-live phase is the official launch of your new ERP solution. You can choose a big bang, phased, or parallel approach based on your risk tolerance and operational needs.

When you are ready to roll out the ERP implementation across your company, choose the approach that best suits your context:

1. - Big Bang: The new ERP system is activated and used exclusively going forward.
  - Phased: The new ERP system is activated in phases to minimize disruptions in operations.
  - Parallel: Both the legacy system and the new ERP system run at the same time.

Step 8: Ongoing Improvements and Feedback

Post-launch, ongoing improvements ensure the ERP solution continues to scale and adapt to your changing business needs. Implementation is a continuous journey of optimization.

The ERP implementation process does not end at the go-live date. As your employees use the software, you will gather user feedback and make ongoing adjustments. This highlights why it is vital to choose an ERP solution that can scale seamlessly as your organization expands.

ERP implementation FAQs

How long does ERP implementation typically take?

Most ERP implementations are completed, from planning to a fully operational system, in six months to one year. Completion times vary depending on the size of the business, the scope of the rollout, the ERP solution, and the vendor. Cloud deployments generally move faster than on-premises projects because there is no hardware to provision and less custom code to manage.

How much does ERP implementation cost?

Several factors drive the cost of an ERP implementation. These include whether the solution will be hosted on-premises (requiring upfront investments in hardware, licensing, maintenance, IT staff, storage, and utilities) or in the cloud (which avoids hardware, software, storage, and most IT infrastructure costs); the vendor’s pricing model (per user or by resources consumed); training and downtime costs, if they apply; and the potential addition of complementary applications in the future. Acumatica’s resource-based pricing means costs scale with usage, not with seat counts.

What kind of training and support should be provided to employees during ERP implementation?

Complete training and support should be provided by the ERP vendor and the ERP implementation partner. Every user should receive hands-on training tailored to their role, plus online resources and partner support after go-live. Depending on the ERP solution, training may or may not be included in the initial cost, so confirm what is covered before signing an ERP contract.

How do I measure the ROI of ERP implementation?

ROI is the comparison of the total cost of ownership (TCO) against the direct and indirect benefits you expect to receive over a five-to-ten-year period. Common savings include increased revenue, reduced operating expenses, improved production efficiency, and better cash flow. Together, cost and ROI provide a clear picture of the economic impact of the ERP solution under consideration.

What are the post-implementation maintenance and support requirements?

Going live is a major milestone, but the ERP implementation journey does not end there. Ongoing support includes reviewing the current setup, adding features that were not required at initial go-live, and accommodating changes to business processes as the system is used in production. ERP software should also receive regular improvements and enhancements. With an on-premises deployment, your IT team owns upgrades, maintenance, and security; with a cloud ERP solution, the vendor handles upgrades and security on your behalf.

How often should an ERP system be upgraded or updated?

Most ERP systems have a useful life of five to ten years, though this varies by product. A modern, easily extended platform that integrates seamlessly with third-party applications and receives regular enhancements based on customer feedback can support the business reliably for many years.

Conclusion

An ERP implementation is a time-intensive, expensive process. Before embarking on an ERP implementation journey, you must be prepared for the challenges that await but recognize that the many benefits the right ERP solution delivers, including increased efficiency, happier employees, and more satisfied customers, makes it all worth it. Now is the time to review the stages of ERP implementation, find the perfect ERP solution for you, and take the first step to implementation success.

An ERP solution connects businesses end-to-end, helping them automate manuals tasks, consolidate all inventory, product, manufacturing, distribution, and project-related information, and find success in the digital economy.
