Transaction advisory services
Transaction advisory services form the multidisciplinary ecosystem that helps buyers, sellers, investors and lenders evaluate, execute and implement corporate transactions.
Definition
Transaction advisory services (TAS) comprise financial, commercial, operational, tax, technology and implementation support surrounding acquisitions, divestitures, investments and related transactions. The label is broad and its precise scope varies among providers.
Scope
TAS developed from financial due diligence but now often includes broader support across the transaction lifecycle. A provider may advise on quality of earnings, working capital, tax, valuation, commercial prospects, technology, operations, carve-outs and integration. Investment banking, legal counsel and regulated securities activity remain distinct even when marketed within a larger transaction platform.

Selecting advisers
Clients should define the decision each workstream must support, how findings will be synthesized and who owns cross-workstream issues. Brand breadth is less important than relevant sector knowledge, senior attention, access to specialists, independence and the ability to convert findings into transaction terms or operating action.
