About these case studies

Real mandates.
Anonymous clients.

Every case study on this page is drawn from real cross-border work delivered by WONE Global Partner firms. Client identities, firm names, and certain identifying details have been anonymised to protect confidentiality. The jurisdictions, timelines, structures, and outcomes are accurate.

What every engagement has in common
One senior partner
The same WONE partner coordinates every jurisdiction. Clients do not deal with different teams in different countries.
Price model
Fixed before work starts
Price is agreed before the first document is drafted — across every jurisdiction involved. No billable hours surprises.
Team assembly
48 hours from brief
From the moment a brief is submitted, a full multi-jurisdiction team is assembled and introduced within 48 hours.

Case Studies

Four mandates.
Four outcomes.

Drawn from Legal, Tax, Advisory, and Audit. Each shows a different type of cross-border complexity — and how WONE resolved it through one coordinated engagement.

Cross-Border Acquisition of a Financial Services Business Across Three East African Jurisdictions

Price agreed

A European private equity firm sought to acquire a financial services business with operations in Kenya, Uganda, and Rwanda simultaneously. The acquisition required regulatory approvals from the financial services regulator in each jurisdiction, employment law compliance across three different employment frameworks, and share purchase documentation governed by the laws of each country. WONE was engaged as a single coordinating partner — assembling specialist lawyers in Nairobi, Kampala, and Kigali under one engagement.

The challenge
Each regulator had different approval timelines — 6 weeks in Kenya, 10 weeks in Uganda, 4 weeks in Rwanda. The transaction was structured to close sequentially, with each closing conditional on the previous. WONE had to coordinate legal teams across three time zones, three legal systems, and three regulator relationships — all reporting to one PE client in London who expected a single weekly update, not three separate email chains.
The outcome
All three regulatory approvals obtained within the projected timeline. The transaction closed across all three jurisdictions in sequence, on schedule, at the agreed fixed price. The client dealt with one WONE partner throughout and received a single consolidated update each week. Elapsed time from brief submission to final closing: 14 weeks.

Transfer Pricing Documentation for a Colombian Industrial Group Across Four Latin American Jurisdictions

Engagement
Fixed
Fee

A Colombian industrial group with subsidiaries in Ecuador, Bolivia, and Argentina received simultaneous transfer pricing inquiries from tax authorities in all four jurisdictions. The intercompany transactions in question — management fees, IP licensing, and shared services — were treated differently under each jurisdiction's local TP rules, and the documentation requirements varied significantly in both content and deadline. WONE assembled a coordinated TP team — one senior tax partner per jurisdiction — under a single engagement managed from Medellín.

The challenge
Each tax authority had different deadlines — Colombia's was the most urgent at 8 weeks. Bolivia required documentation in a specific local format not compatible with the OECD standard used in the other three jurisdictions. Argentina's authority had also issued an information request that went beyond the standard TP inquiry, requiring historical financial records not readily available in a comparable format across the group.
The outcome
Full TP documentation package delivered across all four jurisdictions before the earliest deadline. The Colombian and Ecuadorian inquiries were resolved without assessment. Bolivia's authority accepted the locally-formatted submission and closed without further action. Argentina's inquiry required additional correspondence — WONE continued to manage this through to resolution six months later, within the original fixed fee.

Group Restructuring of a Second-Generation Family Business Across Five European Countries

A second-generation family business with operating entities in Italy, Poland, Austria, Greece, and Luxembourg required a full group restructuring — separating operating companies from holding structures, addressing succession planning across three family branches, and managing the tax and legal consequences of the restructuring in each jurisdiction. The family had retained different advisers in each country, none of whom had visibility of the whole group. WONE was engaged as the single strategic advisory team across all five jurisdictions.

The challenge
The three family branches had different views on the restructuring — one wanted to exit the operating business entirely, one wanted to consolidate ownership in Luxembourg, and the third was concerned about the Italian succession tax implications for their branch. WONE had to design a structure that worked legally and tax-efficiently across five jurisdictions while also satisfying three families with different objectives, different lawyers, and different levels of trust in each other.
The outcome
Group restructuring completed over 18 months. Holding structure consolidated in Luxembourg with a governance framework agreed by all three branches. Succession documentation prepared and executed in each jurisdiction. The exiting family branch received a structure that allowed an orderly exit over five years. All three branches signed the shareholder agreement at the same meeting in Luxembourg — the first time the three branches had been in the same room together in four years.

Group Audit for an International NGO with Field Programmes Across Four East African Countries

Donor audits

Qualifications

Fee

An international development NGO with field programmes in Kenya, Rwanda, Uganda, and Tanzania required a coordinated annual audit that satisfied both the statutory audit requirements in each of the four jurisdictions and the separate audit requirements of three different donor organisations — each with different reporting standards, different definitions of allowable expenditure, and different audit deadlines. Previous auditors had delivered separate jurisdictional audits with no group consolidation — creating annual reconciliation problems and donor compliance failures.

The challenge
Donor A required audited accounts under IFRS. Donor B required accounts under US GAAP with specific grant expenditure tracking. Donor C used its own reporting template that did not map cleanly to either standard. The NGO's internal financial systems were inconsistent across field locations — Kenya used one accounting platform, the other three used a different one with different chart of accounts structures. The statutory audits in each country also had non-aligned financial year-ends.
The outcome
Group audit completed on time across all four jurisdictions. Statutory requirements satisfied in each country. All three donor audit requirements met — including the bespoke Donor C reporting template, which WONE's team mapped to the underlying audit evidence directly. No audit qualifications in any jurisdiction. The NGO also received a consolidated management letter with internal control recommendations for each field office — the first time they had received group-level audit intelligence rather than four separate reports.

The WONE model

The same process.
Every engagement.

These four case studies each look different — different practice areas, different regions, different types of complexity. But the model behind every one is identical.

01
You submit a brief
Tell us about your matter — the jurisdictions involved, the type of expertise you need, the timeline, and any constraints. No call needed first. The brief form takes 5 minutes. You can also call or email directly if you prefer.
02
We assemble your team within 48 hours
A senior WONE partner reviews your brief and identifies the right specialists in each relevant jurisdiction — drawing from the 73 approved member professionals across 30+ countries. Within 48 hours you are introduced to your full team. Every professional has been evaluated and admitted by WONE for their jurisdiction.
03
Price is agreed before work starts
Before any work begins, you receive a fixed-price proposal covering every jurisdiction involved. One price. One invoice. No billable hours. No surprises when the matter becomes more complex than originally scoped — we discuss that with you and agree any change before it affects the price.
04
One partner coordinates everything
You deal with one WONE partner throughout. Local specialists in each jurisdiction work with that partner directly. You receive consolidated updates — not separate emails from lawyers in three different countries. The coordinating partner is accountable for the quality and timing of work in every jurisdiction.
05
Outcome delivered. Matter closed.
When the matter closes, you receive a consolidated closing report from the coordinating partner — not four separate reports from four separate firms. For ongoing relationships, the same partner and team are available for subsequent matters. WONE is not a one-off service — it is a professional services relationship.
