What Skills Do You Actually Need to Succeed in Transaction Services? A Practitioner's Honest List

The Skills Gap Nobody Warns You About

Every transaction services job description lists the same things: strong analytical skills, attention to detail, ability to work under pressure, excellent communication skills. These are accurate but almost completely useless as a preparation guide.

What actually differentiates the analysts who thrive in TS from those who struggle is a specific combination of technical, commercial, and interpersonal capabilities—several of which are never mentioned in job descriptions and are rarely taught in any formal qualification.

Here is the honest list, built from 14 years of doing FDD and observing what separates strong deal professionals from competent but undistinguished ones.

Technical Skill 1: Excel Proficiency at a Deal-Specific Level

The Excel standard in transaction services is materially higher than in most finance roles. You are not building simple budget trackers or summary reports. You are building multi-tab databooks with interdependent schedules, reconciliation checks, and dynamic EBITDA bridges that update as new data arrives.

The specific capabilities you need: PivotTables for rapid data slicing; SUMIFS, INDEX/MATCH, and VLOOKUP for cross-referencing management data; data cleaning and structuring of raw accounting exports (which are rarely formatted conveniently); and the ability to build a reconciliation schedule that can be audited by someone who was not in the room when you built it.

Macros and VBA are a bonus, not a requirement. What is not a bonus is the ability to move quickly, accurately, and without creating errors that cascade through a connected model. Speed matters on a deal. Accuracy matters more.

Technical Skill 2: Accounting Depth That Goes Beyond the Surface

Many finance analysts can read a P&L. Fewer can read a P&L and immediately identify where management has used accounting flexibility to present a more favourable picture.

The accounting depth you need for FDD includes: a working understanding of revenue recognition under Ind AS 115 and the areas where management judgment creates variability; the mechanics of lease accounting under Ind AS 116 and how it affects EBITDA and net debt; the difference between accrual and cash accounting and why the gap between them is commercially significant; and the ability to read audit notes and identify the passages that merit further investigation.

This depth is not achieved by memorising accounting standards. It is achieved by reading real financial statements—hundreds of them—with the specific lens of "where is management exercising judgment, and is that judgment serving the reader's interest or management's interest?"

Commercial Skill 1: Pattern Recognition Across Business Models

The single most valuable commercial skill in FDD is the ability to form a rapid, preliminary view of a business's financial quality—before the detailed analysis is complete.

This pattern recognition is built through deal exposure. After reviewing fifty businesses in a sector, you begin to recognise what a healthy margin profile looks like, what a customer concentration risk looks like in the numbers, and what working capital seasonality looks like in a business with the target's characteristics.

Before that experience is built, you can accelerate its development by: reading deeply in sector-specific contexts (industry reports, comparable company filings, sector M&A coverage), studying worked examples of FDD analyses, and paying close attention to the management commentary in annual reports—particularly when that commentary diverges from what the numbers suggest.

Commercial Skill 2: Writing That Is Concise and Precisely Evidenced

FDD professionals write a lot. Reports run to fifty to one hundred and fifty pages. Executive summaries need to convey the essence of a four-week analysis in two pages.

The standard of writing in TS is higher than most finance professionals are accustomed to. Every finding needs to be: specific (not "revenue quality appears reasonable" but "72% of revenue derives from three customers, of which one contract is under annual renegotiation"); evidenced (the source data that supports the finding); and commercially framed (the implication of the finding for the buyer—valuation, deal structure, or post-acquisition risk).

Vague language in an FDD report is not merely stylistically weak—it is a professional failure. If you cannot describe a finding precisely, you have probably not understood it well enough.

The way to build this skill is to write, get feedback, and rewrite. There is no shortcut.

Interpersonal Skill: Communication Under Commercial Pressure

The interpersonal skill that TS professionals most need—and most underestimate—is the ability to communicate clearly and calmly when the stakes are high and the timeline is short.

Management calls on a live deal are high-pressure situations. A CFO who is protective of their numbers, a CEO who is rehearsing for the narrative they want to tell, and an FDD analyst who needs accurate answers to uncomfortable questions are all in the same room (or video call).

The ability to ask a direct question without being confrontational, to press for a specific answer when the initial response is evasive, and to synthesise what was said in the call into a crisp set of action points—these are skills that take practice to develop.

They are also skills that, once developed, are among the most career-defining in M&A. The FDD professionals who progress fastest are rarely the best modellers. They are the best communicators.
