What is Transaction Services? The Job Explained for 2026

Transaction Services (TS) is one of the most sought-after career paths in corporate finance — and one of the least understood by the candidates who apply for it. This post answers the basic questions: what does the job actually involve, what does a typical day look like, how does it differ from audit or investment banking, and how much do people earn. By the end, you'll know if the role fits your profile and how to prepare your application.

Definition: what is Transaction Services?

Transaction Services is a financial advisory function dedicated to M&A (mergers and acquisitions) deals. Concretely: when company A wants to buy company B, A doesn't just look at B's accounts — it commissions a TS team to produce a rigorous economic analysis of B, called the Financial Due Diligence (FDD) report.

The TS team works either for the buyer (buy-side) or for the seller (sell-side) depending on the engagement, and produces a documented report that frames the price negotiation. Without it, a buyer takes huge risks: overpaying for the target, inheriting hidden debt, or discovering litigation after close.

The job goes by different names depending on the firm:

Transaction Services (TS) at Deloitte, KPMG
Transaction Advisory Services (TAS) at EY, Eight Advisory
Deal Advisory at KPMG
Deals at PwC
Financial Advisory Services or Corporate Finance Advisory at others

The function and deliverables are identical: produce a Quality of Earnings (QoE), analyse the Working Capital Requirement (WCR) or Net Working Capital (NWC), build the net debt bridge, and defend the adjustments needed to move from reported EBITDA to normalised EBITDA — the basis for valuation.

What does a typical day in Transaction Services look like?

A TS engagement typically runs 4 to 8 weeks. The team has a partner (commercial lead), a manager or senior manager (deal pilot), one or two senior analysts and several junior analysts. Here's the split of a junior analyst's day:

30-40% in Excel: building the financial model, EBITDA adjustments, NWC normalisation, net debt bridge.
20-25% in the data room: extracting management accounts, customer contracts, leases, financing facilities. The data room is a secure platform (Datasite, Intralinks, Ansarada) where the seller uploads documents.
15-20% in management interactions: written Q&A with the target CFO, occasional calls with the controller.
15-20% drafting the report: writing sections of the final FDD report (50-150 pages), formalising findings, building exhibits.
5-10% in internal reviews: alignment with the manager, quality reviews, partner feedback.

The average week is 45-55 hours, with peaks at 60-70 hours in the final 7-10 days before deadline. Demanding but bounded — far less extreme than investment banking M&A, where peaks regularly exceed 80 hours.

What are the concrete deliverables?

The three structural deliverables of a TS engagement are the QoE, the net debt bridge and the WCR analysis. Each directly impacts the deal price.

1. The Quality of Earnings (QoE)

The QoE tests the "quality" of the target's reported EBITDA. The analyst goes line by line through the P&L to identify:

Non-recurring (one-off) items: legal fees from a one-time dispute, restructuring costs, gain on asset disposal, Covid-related charges.
Owner-related normalisations: founder paying themselves €200k/year when a salaried CEO equivalent would earn €120k, non-arm's-length related-party fees.
IFRS 16 adjustments: since 2019, operating leases are capitalised, splitting rent into depreciation + interest, which inflates reported EBITDA. For deal comparability, this treatment is often reversed.
Non-recurring revenue: a one-time exceptional contract that won't repeat, an asset sale gain recognised in revenue.

The deliverable is an Excel waterfall that walks from reported EBITDA to normalised EBITDA, each adjustment defensible against the buyer's TS team.

2. The net debt bridge

The net debt bridge determines the amount the buyer must withhold from the purchase price to repay the target's debt. Formula:

Net Debt = Financial Debt + Debt-like items − Cash − Cash-like items

Debt-like items are obligations that economically resemble debt but aren't classified as such on the balance sheet: accrued bonuses, earn-outs from past acquisitions, tax provisions, unfunded pension obligations, customer deposits, recourse factoring.

This is where a strong TS analyst's value shows: spotting an overlooked debt-like item (e.g. an uncollected earn-out from a prior acquisition) can shift the price by several million euros.

3. The Working Capital Requirement (WCR) analysis

The WCR (or NWC depending on the firm's vocabulary) is the structural funding need of the operating cycle. In a deal, a target NWC is fixed in the SPA (Share Purchase Agreement) based on the trailing 12-month average. At completion, actual WCR is compared to target and the price is adjusted euro-for-euro.

The analysis involves:

Normalising the WCR (strip seasonal peaks, exceptional orders, accounting reclassifications)
Benchmarking against sector peers (30-45 day DSO for B2B services, 60-90 days for construction, etc.)
Testing seasonality over 24 months to set a defensible target
Detecting working capital pulls (the seller stretching payables before sale to artificially boost cash)

Buy-side vs sell-side: two variants of the same role

Depending on whether you work for the buyer or seller, the angle changes:

On buy-side, the goal is to identify risks and negotiate the price down. The TS analyst challenges reported EBITDA, hunts debt-like items, contests the target WCR. The buy-side report is used by the buyer to negotiate price and SPA warranties.
On sell-side, the analyst produces a Vendor Due Diligence (VDD) paid by the seller but shared with all potential buyers. The goal is to anticipate buyer questions and defend value. A well-built VDD shortens buyer due diligence by several weeks.

Most analysts alternate between both sides during their career. Useful: you learn to anticipate the other camp's playbook.

How does Transaction Services differ from audit? From investment banking?

Transaction Services vs audit

Audit certifies historical accounts against accounting standards (IFRS, US GAAP). The auditor produces an opinion on past compliance. Retrospective, constrained by standards, focused on legality.

Transaction Services analyses the same numbers from a buyer's economic angle. Forward-looking, constrained by deal logic, focused on value. Reported EBITDA can be perfectly audited AND massively non-representative after TS normalisation.

The audit → TS transition is the most common path: the technical foundation is in place (financial statements, accounting standards), what you need to learn is deal mechanics (normalisation, pricing, SPA logic). See how to switch from audit to Transaction Services.

Transaction Services vs investment banking M&A

Investment banking M&A teams (Lazard, Rothschild & Co, Goldman Sachs, Morgan Stanley, or boutiques like Centerview, Evercore) lead the full transaction on the commercial side: buyer search, price negotiation, calendar management, debt financing sourcing. They produce the valuation models (DCF, trading comparables, precedent transactions).

TS teams support technical due diligence only. The M&A banker builds the theoretical valuation; the TS team confirms or invalidates it based on actual EBITDA and net debt situation.

Bottom line: M&A bankers sell the deal, TS audits the numbers behind the price.

Salaries: how much does a TS analyst earn in 2026?

TS compensation is structured by grade and rises quickly with experience. For a Big 4 firm in continental Europe (Paris) in 2026:

Junior analyst (0-2 years): €38k to €50k + 5-12% bonus
Senior analyst (2-4 years): €50k to €65k + 10-18% bonus
Manager (4-7 years): €70k to €95k + 15-25% bonus
Senior manager (7-10 years): €95k to €130k + 20-35% bonus
Director / Partner: €150k to €400k+ depending on book of business

M&A boutiques (Eight Advisory, Accuracy, Alvarez & Marsal, FTI Consulting, AlixPartners) typically pay 10% to 25% above Big 4 at junior grades, with faster partner exposure. Salaries are 20-40% higher in London and 30-60% higher in the US.

Who does Transaction Services recruit?

Four profiles feed most TS recruitment:

Master's graduates in finance, accounting or audit (Big 4 graduate schemes, MSc Finance from European business schools): direct recruitment from end-of-studies internship into permanent role.
Big 4 or mid-tier auditors with 2-4 years of experience: the most frequent transition, technical foundation in place, learn deal logic on the job.
Investment banking M&A analysts: rarer profile, valued for deal-flow exposure.
Strategy consultants or restructuring practitioners: sourced for transversal analytical skills, will need to fill the gap on chiffré financial analysis.

A CPA / ACA / DEC qualification is valued but not required. A CFA helps for international credibility but isn't decisive.

How to break into Transaction Services?

The standard recruitment process runs over 2 to 4 rounds:

HR screening (30 min): motivation, background, firm fit.
Technical interview with a manager (60 min): questions on EBITDA adjustments, net debt, WCR, SPA mechanics.
Timed case study (60-90 min): given financial data, build a normalised EBITDA, a 12-month NWC analysis and a net debt bridge. Sometimes directly in Excel.
Final round with a partner: fit questions, career project, salary negotiation.

Common technical questions: "Walk me through an EBITDA normalisation"; "What's the difference between NWC and WCR"; "Give me a debt-like item example"; "How do you treat IFRS 16 in a deal". To prepare: see our Transaction Services Programme or the detailed list of Big 4 TS interview questions.
