What is the best ERP for a mid-size company growing by acquisition?
Sage Intacct is the best ERP for most mid-size companies growing by acquisition, because its fit is multi-entity accounting, reporting and dashboards, which is the first thing a buyer needs from each company it adds. A custom system built by Black Badger ranks second, as a layer you own that pulls the numbers and operations of every acquired company together without forcing each one onto a new ERP at closing.
Technical groups that will run a multi-company setup themselves
Published per-user price with a wide set of apps under one fee
Choice of hosting, including on premise on the Custom plan
Portal users such as customers and suppliers are not charged
Implementation and custom code maintenance are not in the plan price
Multi-company use and Studio need the dearer Custom plan
Companies over 50 employees usually work with a partner
The ranking, entry by entry
1 Sage Intacct
Best for acquirers that need consolidated books across many entities
An acquirer needs the books of each new company in one place quickly, long before operations are merged. Sage Intacct is first because that is the job it is suited to. Sage describes it as designed for scaling and mid-sized businesses with complex accounting needs, and its fit is multi-entity accounting, reporting and dashboards with operations handled in other tools. Acquired companies can keep running what they run while finance comes together.
Watch for. Sage publishes no price and builds the quote around the organization. Ask what adding an entity costs, since you plan to add several.
How it charges
Quoted by sales to the size and needs of the organization
Main limit
Quote only, built around accounting for mid-sized firms
Best for acquirers whose companies will keep different systems
Black Badger, the publisher of this guide, builds custom software, and for an acquirer that often means one system over the systems each company keeps. Each company you buy arrives with its own ERP or accounting package, and replacing them all is slow and risky. We build one system you own that reads from each of them and gives management a single view of orders, stock and cash. Adding a company adds no licenses and no per-seat fee.
Watch for. The scope has to say which system holds the authoritative copy of each kind of record. That is settled in discovery, before anything is built.
How it charges
One-time build scoped in writing, then running costs such as hosting
Main limit
Needs a scoping call first, and suits companies of 50 or more employees
Best for acquirers that move every company onto one cloud suite
NetSuite is third. The other strategy for an acquirer is to move each acquired company onto the same system, and NetSuite suits that because it is one vendor-managed cloud product with accounting, inventory and order management in the core platform. It ranks below the first two because every migration is a project, and the license grows with the users and modules each new company brings.
Watch for. Its pricing guide lists data migration and implementation as costs beyond the license. For an acquirer those costs repeat with every deal.
How it charges
Quoted annual license by modules and users
Main limit
Quote only, and each module is licensed separately
Best for acquirers adding many users with each deal
Acumatica ranks fourth. An acquisition can double the number of people who need access at once, and Acumatica does not price by user seats. Its cost follows the applications you deploy, expected usage and deployment option. That makes the bill after a deal easier to predict than a per-user quote. It trails NetSuite here because buying and implementing run through a reseller, which adds a party to every integration project.
Watch for. A larger group means larger resource needs. Have the reseller show how the price moves when a company of your target size is added.
How it charges
Quoted by applications and usage, not by user seats
Main limit
Quote only, sold through resellers, priced by resources and not by users
Best for acquirers that impose one standard process on every company
SAP S/4HANA Cloud is fifth. An acquirer that wants every company it buys to adopt the same preset processes will find that SAP is built on that idea. SAP sells packages for finance, supply chain or HR at a rate that drops as users are added. It ranks lower because acquired companies rarely fit a preset process on arrival, and SAP is not the fit for a business that needs heavy changes to how the system works.
Watch for. Check the package scope against the smallest company you expect to buy, since packages are scoped by area and carry a 15 user minimum.
How it charges
Per user, 15-user minimum, rate varies with user count
Main limit
Sold as fixed packages with a 15 user minimum, rate depends on user count
Best for microsoft-based groups buying smaller companies
Business Central ranks sixth for acquirers. Its published per-user prices make it simple to cost a newly acquired company before the deal closes, and a group already on Microsoft tools keeps one vendor. It sits low on this list because each acquired company still has to be purchased and set up through a partner, and per-user licensing rises with every team you bring in.
Watch for. Count how many acquired staff need a full license and how many can use the limited Team Members license.
How it charges
Per user, paid yearly, bought through a Microsoft partner
Main limit
Manufacturing needs the Premium plan, and Microsoft sends buyers to a partner
Best for technical groups that will run a multi-company setup themselves
Odoo is seventh. It does offer multi-company use, and that is what moves a customer from the Standard plan to the dearer Custom plan, billed per user and yearly. A group with its own technical staff can use that to bring small acquisitions onto one system at a published price. It ranks last because implementation and the upkeep of custom code sit outside the plan.
Watch for. Only the Custom plan can be hosted on Odoo.sh or on premise. Decide on hosting before you plan the second company.
How it charges
Per user, billed yearly or monthly, one app free
Main limit
Mid-size firms usually need a partner, and Custom adds multi-company and Studio
We ranked for a mid-size company that has bought at least one other business and expects to buy more. The test was how fast a newly acquired company can be brought into the group's numbers, and what each added company costs in licenses and migration work.
An acquirer has two workable strategies, which are to consolidate finance and leave operations alone, or to move everyone onto one system. The top two entries serve the first and the next three serve the second.
Questions buyers ask
Should an acquired company move onto the parent ERP right away?
An acquired company should rarely move onto the parent ERP right away. The first need is consolidated financial reporting, and that can be met without touching how the acquired company takes orders or ships. Moving its operations onto a new system is a separate decision that is best made once you understand how that business runs.
What does each acquisition add to an ERP bill?
With per-user products each acquisition adds a license for each new user, plus migration and implementation work. With NetSuite it may also add modules, each with its own fee. Acumatica prices by applications and resources and not by seats. A custom system you own adds no licenses and needs only the work to connect the new company.
Can one system sit on top of several different ERPs?
Yes, one system can read from several different ERPs, and that is a common design for a custom build. The system reads from each company's existing system and presents one set of numbers and one view of operations. Black Badger builds this kind of system, and the scope names which records come from where.
