Nine engagements across close transformation, treasury, M&A diligence, margin and working-capital work, valuation defense, lender restructuring, and purchase-price allocation — drawn from 13+ years at PwC, BDO, and a leading global accounting advisory firm. Anonymized by design; the numbers are real.
A private-equity-backed multi-entity operating company brought me in as acting controller with one mandate: fix the close. The existing process ran 20 business days end to end, across three continents, on disconnected systems with no standardized chart of accounts and no reliable reconciliation cadence. Every month, finance leadership flew blind for the first three weeks of the new period.
I rebuilt it from the ground up. The close calendar was redesigned around entity-level deadlines feeding a consolidated timeline with accountability at every node. The chart of accounts was standardized across all entities. Manual reconciliations were automated, removing the single biggest source of delay and error. Within one quarter the close compressed from 20 business days to 5 — a 75% reduction that held and became the new baseline.
The result wasn't just speed. It was visibility: sponsors had consolidated numbers in week one, and finance could operate as a forward-looking function instead of a month-end recovery operation.
“We had lived with a painful close for years and assumed it was structural. It wasn't. Within a quarter we had a process that actually worked, and a team with time to do real analysis instead of chasing reconciliations.”
A multi-currency operating company engaged me for treasury advisory. The presenting issue was vague: management felt uneasy about FX exposure but couldn't quantify it. That unease was warranted.
A diagnostic of the P&L and management reporting revealed a structural problem. FX exposure was embedded in the business but invisible in the way results were reported — gains and losses flowed through the income statement with no framework to isolate, measure, or hedge them. The CEO had no line of sight to a risk moving the numbers every period.
I designed and implemented a hedging program calibrated to the company's actual exposure profile, alongside reporting that surfaced FX impact as a discrete, visible line. For the first time, leadership could see the exposure, track it, and decide deliberately how much risk to carry.
“We knew something was off with how FX affected our results but couldn't see it clearly enough to act. This went from diagnosis to implementation fast — we ended up with real control over something that had been an invisible drag.”
Across Big Four engagements spanning more than 100 M&A deals and over $2 billion in capital-markets transactions, a pattern repeated with near-perfect consistency.
Companies arrived at diligence in strong commercial shape — credible teams, solid revenue, defensible positions. Then the technical-accounting review would begin. Revenue recognition under ASC 606 with performance obligations never properly identified. Lease liabilities under ASC 842 never recorded. Convertible instruments under ASC 470/480 never analyzed for bifurcation or classification. Not fraud — just complexity that had outpaced the finance function.
Each is a deal risk: the potential to reprice a transaction, extend a timeline, or collapse a deal that should have closed. And each is fixable — if it's caught before the buyer does. The work was technical-accounting remediation and readiness: identify issues early, quantify impact, develop the position, and prepare the memos that gave buyers confidence the numbers meant what they said.
“Having someone who could sit across from the Big Four diligence team and engage on the technical substance made a real difference. That capability is hard to find and easy to underestimate until you need it.”
B2B services firm in the mid-single-digit-millions range. A respectable blended margin headline — but management couldn't say which clients or service lines were actually profitable.
Built true client-level P&Ls with proper indirect-cost allocation. The bottom 30% of accounts were unprofitable at contribution margin once costs were honestly assigned. Repriced or exited them on a structured timeline.
Net margin expanded ~9 points in under a year. Zero revenue attrition from the repricing wave.
Mid-market PE-backed services platform. DSO running at more than twice net terms — revenue trapped in receivables and constraining M&A capacity.
Built collections discipline: aging cadence, automated reminders, dispute escalation, terms enforcement tied to sales comp. Re-papered top contracts to align commercial terms with working-capital reality.
DSO compressed by half in two quarters — funding the next bolt-on without drawing the revolver.
Mid-market ARR SaaS platform preparing for a transaction. Financials reported ARR on a contract-signed basis, commingled services revenue, no cohort retention — the stack a sophisticated buyer tears apart.
Rebuilt the metric stack — GAAP-aligned ARR, recurring vs. services separated, net retention documented by cohort. Produced the audit-ready data room before the buy-side QoE firm arrived.
Buyer's QoE returned ARR higher than the seller reported. Documented retention defended a multiple the seller couldn't have argued without the data.
When a portfolio company is in soft default on a leverage covenant, the wrong move is to scramble into the lender meeting empty-handed. The right move is to arrive with the documentation already done.
Rebuild trailing-twelve EBITDA with rigorous, documented normalizations. Categorize add-backs by type and contestability. Produce a forward 12–18 month covenant-compliance forecast. Lead with the numbers, not the narrative.
Covenant holidays. Leverage resets. Refinance avoided entirely.
When a lead investor pushes back on recurring-revenue quality, churn methodology, or margin classification, the founder's leverage depends on how fast and cleanly the rebuild happens — your data versus their portfolio benchmarks.
Rebuild the ARR walk with full cohort detail. Defend churn methodology against the alternatives the investor is calibrating to. Reclassify COGS to reveal true gross margin. Bring documentation, not argument.
Founder closes at target valuation. Dilution from the counter avoided.
Post-acquisition accountants often book the entire excess over net assets as goodwill — a placeholder that creates impairment risk, audit scrutiny, and complications for the next transaction.
Identify separately identifiable intangibles — customer relationships (income approach), developed technology and trade names (relief-from-royalty), non-competes (with-and-without). Assign defensible useful lives. Document each method, audit-ready.
Goodwill correctly stated — materially lower than the placeholder. Statements that survive the next audit.
Every case study here is anonymized by design. Revenue appears as ranges, not points. Outcomes are stated as percentages or magnitudes, not specific dollar amounts. Industry profiles are generalized; timing is described in duration, not by year.
Cases marked Methodology describe the playbook itself — the disciplined approach to a recurring deal-side problem — rather than the mechanics of any single engagement. The most identifiable cases are described as approaches, not transactions.
