IT Due Diligence

Anticipating the cost of technology

IT is increasingly a key factor in enabling post deal business development initiatives, and successful integration and separation programmes.

Identifying the need

Due to the financial focus and the confidential nature of M&A transactions, IT departments are often not consulted until late in the process. This often adversely affects the anticipated post deal financial results as IT costs and timescales can be underestimated/misunderstood.


What we do

At Deloitte, we have a range of pre and post transaction core services, tailored to suit individual client’s challenges, to help ensure that IT is a successful enabler for the transaction lifecycle.

We regularly work with both corporate and private equity investors, on both the buy and sell-side of transactions, and on IPOs. We have a dedicated IT Due Diligence team and bring in specific technical and industry experts for each transaction from our extensive technology consulting business.
We work either as part of a combined diligence team, together with our financial, tax, operational, commercial, risk, cyber and other diligence colleagues, or on a standalone basis for our clients.
