CONTEXT

Project Context

MangoPay operates in a multi-currency, multi-entity environment that demands surgical precision. Spreading treasury management across 14 partner banks created daily operational complexity: manual reconciliations, undetected discrepancies, and consolidated reporting that was impossible in real time.

Each new subsidiary, each new counterparty bank opened its own communication channel, its own file formats, its own exceptions. The marginal cost of a bank onboarding was becoming prohibitive and was holding back the group's European expansion.

The challenge was to consolidate these critical flows within a single, modern system (SAP S/4HANA) to deliver real-time visibility on liquidity, automate interbank reconciliation and industrialise the onboarding of new banking partners.

Strategic Objectives

OBJECTIVES

(01)

Flow modernisation

Fully redesign interbank exchanges using the ISO 20022 and SWIFT standards, to make cross-border payments more reliable and reduce operational friction across 14 European counterparty banks.

(02)

Group consolidation

Unify treasury management across all MangoPay subsidiaries and legal entities, with a real-time, multi-currency and multi-geography view: no more country silos, replaced by a central cockpit for the CFO and treasury.

(03)

S/4HANA migration

Secure the transition to the new generation of SAP ERP without interrupting payment operations, with a blue-green strategy on the FI/CO and Treasury modules, and zero impact on interbank SLAs.

Solutions Delivered by Adservio

SOLUTIONS

Adservio mobilised a multidisciplinary team (Solution Architect, SAP Consultants, Treasury Engineers, Project Manager) to lead this transformation over 18 months.

(01)

Financial flow architecture

Design of a cloud-native infrastructure for communication with the 14 counterparty banks via APIs and the SWIFT/ISO 20022 standards. Implementation of a central orchestrator guaranteeing idempotency, deduplication and immutable logging of every transaction.

(02)

SAP S/4HANA integration

Configuration and rollout of the Treasury and FI/CO modules for automatic, intelligent reconciliation of inter-entity flows. Implementation of multi-criteria matching rules (amount, currency, value date, counterparty) with fine-grained exception handling.

(03)

Process optimisation

Audit and re-engineering of treasury processes to eliminate manual tasks, reduce the risk of error and automate the production of regulatory reporting (CRD IV, ACPR). A 60% reduction in daily reconciliation time.

(04)

Performance steering

Setting up executive steering with real-time treasury KPIs, rigorous test plans (UAT, regression, load testing) and tracking reports to guarantee the compliance of financial flows at every release.

(05)

Change management

SAFe coaching across 4 agile release trains, dedicated Treasury / Compliance / DevOps training, and the creation of a living documentation repository to equip MangoPay teams over the long term.

All the group's cash, on a single screen,
updated to the second.

The SAP S/4HANA cockpit consolidates cash positions in real time across all subsidiaries and all currencies. The central hub orchestrates SWIFT and ISO 20022 flows with the 14 counterparty banks: 8,920 transactions per second, 312K per day.

WHAT IT CHANGES

Unified treasury

A consolidated, real-time view of the cash position across all subsidiaries and all banks. A central cockpit rolled out for the CFO, with currency and investment trade-off decisions cut from several days to a few minutes.

Faster close

Reduced interbank reconciliation time thanks to SAP automation: the monthly close moves from 8 days to under 5, freeing up team capacity for value-added analysis.

Controlled scale-up

The architecture supports MangoPay's growth with no degradation: processing capacity multiplied by 3, with no manual intervention and no increase in treasury headcount.

Fintech scalability

An architecture ready to support the addition of new banks and new geographies in a few days rather than several months: industrialised bank onboarding via ISO 20022 templates.

Compliance & security

Full alignment with international banking security standards (SWIFT CSP, ISO 27001) and ACPR/EBA requirements. Internal and external audits validated with no major reservations on the Treasury scope.

Accelerated time-to-market

New bank connections or protocol changes reach production in a matter of days, versus several months before: a decisive competitive advantage in a fast-consolidating fintech market.
