What actually doubles the day it closes.
The announcement describes two companies becoming one. For a while they are running two of everything that operates the business: finance, customers, orders, tickets, payroll. None of that is in the press release. It shows up in the first quarter.
Both stacks are live on Monday.
Customers, invoices, and inventory still live where each company left them. Someone reconciles them by hand, or a migration starts before either side is ready to retire a system.
A roll-up does this on a schedule.
Each add-on arrives with its own systems already wrapped around its own customers. Absorbing the next one quickly is part of the thesis, and the previous one's seams are often still open.
In the MSP channel alone, Omdia tracked 169 announced deals in 2025, private equity in 69% of the disclosed ones. The write-up is here. The mechanism is the same when a manufacturer buys a competitor or a software company absorbs a product line.
The longer the two stacks stay apart, the more it costs.
Integration debt works like technical debt. A disconnected pair of systems is double the licensing and a person in the middle of every record that has to agree. Forcing one surviving system means retraining the people and remapping every workflow at once, on the deal's timeline.
Cross-sell and a single view of the customer are what the deal was sold on. They wait on the systems agreeing. The systems do not agree because a slide said they would.
Connect them before you retire either one.
The engine reads an API and writes the connector: discovers the surface, infers the mapping, and repairs it when either side changes. Customers, invoices, and orders can move between the two companies while each system is still the one its people know.
A mapping the engine is sure about, it handles. Below that line, a named person answers a question with the engine's best guess attached. Retirement of a system can follow the relationship, on the timeline that relationship can stand, once the records already agree.
Keep the platform you already have.
Many of these companies already run MuleSoft, Boomi, Workato, or a stack of scripts their integration partner built. That work can stay. The people who know it keep it. An in-flight project does not have to stop so a team can retrain before the deal can move.
The engine takes the seams that platform is not staffed to open during the integration window: the acquired company's systems, and the connections that break when either vendor ships a change. The flows already running on the other platform stay there.
The comparison is for a team that is choosing a platform. This page is for a team that is closing a deal and cannot spend the quarter switching one.
