What Is a Post Merger Integration Checklist? Why do You Need One?

A post-merger or post-acquisition integration plan checklist is a list of activities that need to happen for a merger of two or more companies to realize the success envisioned. This would include capitalizing on the synergies between the companies and ensuring that value is added and not removed from the newly merged organization.

Because of all the complex changes that happen in both companies during a post-merger integration process, it’s important to have a list of steps or tasks outlined and categorized for each area of the organization that will be impacted, all of which are captured in a company integration checklist.

Get Your Free OCM Account and Access Free M&A Integration Resources

Some best practices when using a post-merger or post-acquisition integration checklist are:

  • Keep one main merger checklist integration document (do not have duplicate, siloed copies).
  • Securely share the integration plan template with those that are responsible for tasks listed on the checklist.
  • Add a recurring calendar item to help ensure you regularly update your M&A integration checklist.

The free M&A integration checklist can be leveraged and then share with the teams responsible for each area of the company.

What Can Cause a Post Merger Integration Process to Go Wrong?

Often companies will hire consulting firms when going through a major change such as a merger or acquisition because there is so much at stake if it’s not handled correctly. They may align with a McKinsey post merger integration team, for example, to ensure that nothing is left to chance and that the transition is handled by professionals that do this all the time.

When a post-merger integration process goes wrong, it can result in a company losing value, employees leaving in droves, customer retention problems, and other issues, which is why it is essential to use a post merger integration framework.

Here are some of the things that can cause mergers and acquisitions integration to go awry.

1. No Change Management to Prepare the Two Organizations

If change management isn’t part of the post-merger integration plan, then the people going through the major transition of an M&A can become an afterthought. This can result in talent upheaval, roles and reporting confusion, and more.

Using the free OCMS change management “merging two companies checklist” can help increase the success of your post-merger integration efforts.

2. Not Defining a Clear Post Merger Integration Plan

You can’t take a “we’ll see how it goes” or “we’ll cross that bridge when we get there” mentality if you want to ensure a successful organization post-merger. You need to have a detailed M&A integration plan if you want the organization to achieve success and increase value after the merger has happened. Using the post-merger integration framework outlined in this guide will guide you in developing an efficient plan for integration.

3. Underestimating the Complexity of the Merging Companies

Leaders that underestimate the complexity of how the merger will impact both companies will often run into issues after the post M&A integration is completed on paper.

Using a OCMS Portal change impact assessment tool for M&A and a “merging two companies checklist” provides a place to lay out in detail the complex nature of the transition, identify which internal and external groups are being impacted, and manage it competently.

4. Not Having a Company Merger Checklist

If a company doesn’t have a Day-1, 50-Day, or 100-Day integration plan checklist to catalog an outline of activities that can be checked off as they happen, things can easily get missed. When this happens, companies that have merged will end up running into problems once the two teams are integrated.

In order for a post merger integration framework to be effective, it needs to include a defined and seamless integration plan template like the free OCM Solution post merger integration process checklist template offered below.

5. Focusing on Logistics Over Value & People

Too much focus on logistics, like legal documentation, integration of technology systems, new corporate branding, etc., and not enough on value creation and people can lead companies that have merged to miss the mark.

The new enterprise can suffer from value loss, so even if the technical logistics were handled well, the project ends up failing due to major issues.

Post Merger & Post Acquisition Integration Plan Checklist

Below, you’ll find a merger checklist integration template that you can use as a guide for managing a merger or acquisition for an organization. This company merger checklist is divided into seven key company areas.

When you download the OCMS Post Merger Integration Checklist xls file at the end of this section, you’ll find that we’ve outlined some of the key checklist tasks to include in each area (these are also noted below). You should also add other tasks that are pertinent to the specifics of your M&A project and the organizations that are merging.

Your post-merger or post-acquisition integration checklist should include the following.

1. HR & Personnel Post Merger Integration Plan

Companies that have merged will have personnel in certain job roles that will need to be integrated into various departments. This may involve an adjustment of duties or laying off some staff due to redundancies.

Beyond department and job role structures, there are also the basic HR processes that need to be handled, such as onboarding and entering all employees into one HR system.

HR and personnel integration plan template tasks:

  • Restructure staff to the various organizational departments/business units.
  • Provide employees undergoing role changes with a clear outline of responsibilities and job descriptions.
  • Onboard employees that need onboarding to new processes and procedures.
  • Incorporate all employees into the HR and payroll/benefits systems.
  • Address position redundancies and execute a plan to either reposition or dismiss staff.

2. Finance & Accounting Post Merger Integration Plan

There will be a number of finance and accounting tasks that need to be completed as part of your integration plan template. The OCM Solution template is designed to be used as your post merger integration finance checklist.

In some cases, an entirely new company may be forming from two companies that have merged. In other cases, the main company may remain the same, but be integrating financial assets or debts from an acquired organization.

Finance and accounting tasks for a 100-day integration plan checklist:

  • Integrate banks accounts for the merging companies.
  • Integrate assets for the merging companies.
  • Integrate debts for the merging companies.
  • Create an opening balance sheet post-M&A.
  • Update company details for vendors, lenders, and other financial contacts that need to be updated.
  • Address tax planning and strategy.

3. Organization & Culture Merger and Acquisition Checklist Tasks

If you are creating an entirely new organization as part of your M&A integration plan, there will be a lot of tasks that you’ll need to accomplish in the area of organization and culture.

On the other hand, if you’re working with an acquisition integration checklist and one company is being folded into another that will be keeping its structure and culture, then the work will involve indoctrinating the team from the acquired company into your existing organization.

Organization and culture tasks for an M&A integration checklist:

  • Create a new organizational chart.
  • Deploy change management plans before and after the merger to ensure everyone has the support they need to be successful post M&A.
  • Handle all legal documents, name changes, etc.
  • Create materials documenting the new or existing corporate culture and meet with staff for culture onboarding.
  • Update the organization’s mission statement, vision, priorities, etc. as necessary.
  • Update company systems or procedures and accompanying documentation.
  • Deploy corporate communications internally and externally regarding the merger/acquisition.

Use the free OCM Solution company acquisition integration checklist for your post M&A organization and culture activities.

post acquisition integration checklist4. Technology & Physical Space Post Merger Integration Plan

As part of the logistics of mergers and acquisitions integration, there will be changes to technology that need to be addressed. For example, putting all employees on the same business app accounts, and ensuring that everyone is protected by the same IT security strategy.

Some M&A activities may also involve moving employees physically from one location to another, in which case physical space considerations will also be a part of any checklist, whether it is your own company merger checklist or one by a consultant, like a McKinsey post merger integration checklist.

Technology and physical space post-merger / post-acquisition integration plan checklist tasks:

  • Update software to ensure uniformity.
  • Ensure all employees are on the same cloud application company plans.
  • Issue user credentials for new users.
  • Review hardware and ensure all devices are secured to company cybersecurity standards.
  • Integrate all network systems.
  • Review mobile device policies for both companies and integrate, issuing new devices where needed, or adding new users to a company mobile device manager.
  • Conduct a post-merger IT security audit to identify any vulnerabilities.
  • Train employees, as needed, on data privacy and IT security policies.

You can use the free OCM Solution M&A IT integration checklist for your post M&A technology and systems integration activities.

5. Sales, Marketing & Customer Service Post Acquisition Integration Checklist Tasks

When working on post M&A integration, there may be changes that impact the products and services that an organization provides. Products may be added, and branding may also change to reflect a new company direction.

Customer service may also go through a transition that is designed to improve customer experience.

Some tasks for the sales, marketing, and customer service areas of a post-acquisition integration checklist are:

  • Update products/services offerings as needed.
  • Align sales and marketing team with new organizational offerings and goals.
  • Align customer support team with any new customer initiatives.
  • Develop post M&A corporate branding and messaging, and deploy.

6. Supply Chain Management Post Acquisition Integration Checklist Tasks

 Another area on a merger checklist integration template will be related to supply chain management. This would be pertinent to any companies that receive materials and ship out products to customers.

Typical tasks related to supply chain management on your merging two companies checklist include:

  • Consolidate warehousing and storage between the merging companies.
  • Renegotiate/reconfigure outsourcing agreements as necessary.
  • Coordinate shipping and fulfillment processes.
  • Review suppliers and update agreements to reflect the new merged company’s needs.
  • Update shipping calculations in e-commerce and other platforms based on new locations as needed.

7. Production Merger and Acquisition Checklist Tasks

If either one of the two companies that are merging manufactures any products, then production will need to be addressed and streamlined to reflect the goals of the integration plan template.

There may be equipment or facilities that are no longer needed, or the newly transformed organization may be expanding production capabilities and need to standardize procedures across the new company.

As part of the post-merger integration process for production, here are some of the tasks that would be on the M&A integration checklist:

  • Review production facilities and identify redundancies in equipment.
  • Identify the production sites that will be used post-merger.
  • Execute a plan to move production equipment as necessary.
  • Execute a plan to sell or decommission unneeded production equipment.
  • Review production sites that have been added to apply systems and procedures per company policies.

Post-Merger Integration Plan FAQs

What happens in post-merger integration?

During a merger or acquisition, two companies are merging into one. In post-merger integration, you need to ensure all the people, systems, facilities, processes, culture, etc. are appropriately integrated. Using an integration plan template and checklist can help ensure that all facets of both companies are accounted for and aligned in every department.

Why do mergers fail?

When a post-merger integration process goes wrong, it can result in a company losing value, employees leaving in droves, customer retention problems, and other issues. Here are some of the things that can cause mergers and acquisitions integration to go awry.

• No change management to prepare the people in the two organizations
• Not defining a clear post-merger integration plan
• Underestimating the complexity of the merging companies
• Not having a company post-merger checklist
• Focusing on logistics over value & people

How do mergers and acquisitions relate to organizational change?

Mergers and acquisitions are one of the types of transformations that involve a lot of things that are changing. Roles and responsibilities, corporate culture, processes, systems, policies, and more can be changed during M&A. Because the number of changes is usually quite high during M&A, the importance of change management is magnified. Through effective change management practices, you can mitigate negative impacts on employees and increase their buy-in, support, and engagement in the newly transformed organization.

What is the importance of change management in mergers and acquisitions?

According to a survey by McKinsey, organizational problems like failure to adopt a new corporate culture or changed operating models are responsible for nearly 50% of the failure when mergers don’t meet projections. Change management before acquisition helps prepare everyone for the changes to come so there is less apprehension and resistance. Change management after acquisition helps everyone to adapt to their new normal and successfully transition to the new corporate culture, systems, and other changes.
