IT Integration: Bringing Acquired Locations onto One Platform

Buying another HVAC, plumbing, or electrical company brings new customers, technicians, and trucks. It also brings a second set of systems, passwords, and habits. A clear IT integration plan helps the new location work like part of the company without disrupting service.

Assess the acquired company first

Before changing anything, learn what you are inheriting. Ideally, start this review during due diligence, before closing. At a minimum, begin on day one.

Find out which field service platform, accounting system, and phone service the shop uses. Also identify who controls the domain name, the website, and admin passwords. Sometimes a former owner or a relative holds them personally.

Look for security gaps too. For example, an acquired shop might have no multifactor authentication or no working backups. Those gaps become your risk the moment the deal closes.

Secure the new location right away

You do not need to merge everything at once. However, a few security steps should happen within the first days.

• Change admin passwords on email, domain, website, and banking accounts.
• Enable multifactor authentication on every email account.
• Install endpoint protection on every computer and server.
• Confirm that backups exist and that you can restore from them.
• Remove access for former owners and departed staff.
• Warn the office team about fake payment requests during the transition.

That last step matters because criminals watch for acquisition news. A transition period, with new bank details and unfamiliar names, is ideal for fraud.

Plan your IT integration in phases

A phased approach limits disruption for customers and technicians. So decide what moves first and what can wait.

Typically, email and identity come first, since they control access to everything else. Next come devices and security tools. Then line-of-business systems such as field service and accounting follow, often timed around the slower season.

Set a target date for each phase, and share it with the new team. People handle change better when they know what is coming.

Also plan for phones early. Customers call the number on the old truck wraps, so keep that number working and route it into your main system.

Merge Microsoft 365 and email

Moving the acquired company into your Microsoft 365 tenant gives everyone one directory, one set of security policies, and one Teams environment. It also simplifies licensing.

Plan the email domain carefully. Many contractors keep the acquired brand for a while because local customers know it. In that case, you can add the old domain to your tenant and keep both addresses working.

Also migrate mailboxes, OneDrive files, and shared folders on a set weekend. Then help each user set up multifactor authentication and their mobile apps on Monday morning.

Move field service and customer data carefully

Field service data is the heart of the acquired business. It holds customer history, equipment records, and maintenance agreements. So treat this migration as the most important part of the IT integration.

First, clean the data before moving it. Remove duplicate customers and fix addresses, since both sources often share some customers.

Next, run a test import and have dispatchers review it. Check that maintenance agreements, pricing, and equipment records came across correctly.

Finally, schedule the cutover for a slow week, and keep read-only access to the old system for a while. Technicians will need old service notes long after the move.

Standardize devices, networks, and support

After the major systems move, bring hardware and networks in line. Replace aging computers and consumer-grade routers. Enroll truck tablets in your device management platform.

Then retire any old accounts, servers, and subscriptions the acquired shop no longer needs.

In addition, give the new location the same help desk process as everyone else. Consistent support helps new technicians feel like part of one company.

Finally, document the whole process as you go. If you plan more acquisitions, that record becomes a playbook for the next IT integration.
