SAP Global Rollout at Scale, Without Compromise
Extending SAP across regions, business units, or newly acquired entities is one of the most complex SAP challenges organisations face. Aevitas IT has a proven track record of delivering structured, phased rollouts that maintain global consistency while respecting local requirements.
- What We Deliver
Multi-Region SAP S/4HANA Rollouts
Aevitas IT manages SAP rollouts using both 1-Tier (single global instance) and 2-Tier (central enterprise ERP with satellite systems) strategies, selecting the right model based on your operational structure, regulatory environment, and integration complexity. Our approach spans the full rollout lifecycle — from global template design through phased country deployments, localisation, and final cutover.
We have delivered rollouts across the Americas, Caribbean, and Europe, navigating language, currency, tax, and regulatory differences with experience accumulated across dozens of country deployments.

All entities operate on one SAP instance. Consistent global processes, unified real-time reporting, and lower infrastructure footprint. Ideal for organisations with standardised operations.
2-Tier Architecture
Enterprise SAP S/4HANA
Core ERP — Group Level
⟵ SAP Integration Suite ⟶
Subsidiary
S/4HANA A
Subsidiary
S/4HANA B
Central system for enterprise-wide processes; subsidiary or regional systems for distinct operations. Suited to acquired entities, regulated subsidiaries, or operations requiring local autonomy.
- Our Methodology
Global Template. Local Precision.
Migration Roadmap & Strategy
We begin with a thorough assessment — evaluating your current landscape, integration dependencies, greenfield vs brownfield considerations, and business unit priorities — to define a phased rollout roadmap that balances speed with risk.
Global Template Design
A global template establishes the standard processes, configurations, and design decisions that apply across all deployments. Built correctly, it accelerates every subsequent rollout wave and ensures operational consistency across the organisation.
Phased Country Deployments
Each rollout wave is planned to minimise disruption to live operations. Local business users are engaged early, localisation requirements are validated, and country-specific cutover plans are executed with dedicated in-country support.
Data, Reporting & UX Optimisation
Post-rollout, we standardise data models and reporting structures across entities and optimise the user experience — ensuring employees in every country get consistent, intuitive access to the tools they need.
- PROVEN IN THE FIELD
Location: Latin America
Unifying SAP operations across 22 countries
A rapidly expanding telecommunications provider was operating multiple SAP and non-SAP ERP systems following a series of mergers and acquisitions. Aevitas IT implemented a centralised SAP S/4HANA platform, introduced consistent processes across 22 countries and used SAP BTP to help harmonise the wider technology landscape. The programme improved process and data consistency, reduced operating costs and made it easier to integrate newly acquired companies.
AI in SAP Rollouts
As SAP Business AI (Joule) becomes standard in S/4HANA deployments, Aevitas IT ensures every rollout wave activates AI capabilities consistently across all regions. We also leverage AI-assisted testing tools to validate global template adherence and detect localisation gaps faster — significantly reducing rollout cycle times.
- Automated regression testing across rollout waves reduces manual testing by up to 60%
- AI-generated localisation gap analysis accelerates Explore phase per country
- Consistent Joule activation across all regions, configured for local language and process context
- SAP's embedded AI in finance, supply chain, and procurement activated at go-live

The Aevitas Advantage in Rollout
We have delivered a single SAP S/4HANA rollout covering 22 countries — one of the most complex multi-region deployments in the Americas and Caribbean.
Our consultants have direct experience of tax, regulatory, and operational requirements across Latin America, the Caribbean, North America, and Europe — reducing localisation risk.
We build global templates with governance built in — protecting template integrity while creating structured processes for managing local variations that are genuinely required.
Accelerators, pre-built localisation configurations, and reusable test packs allow us to compress rollout cycles without cutting corners on quality or compliance.

- FAQ
Frequently Asked Questions
The global template carries the standard processes and data model; local requirements, statutory reporting, tax procedures, e-invoicing mandates are handled through a governed localisation layer defined during template design, so country-specific rules don't fragment the core build.
Because the global template already exists, onboarding a new entity is largely a matter of applying the template and handling its specific localisation needs, significantly faster than building a new implementation from scratch, which is one of the main efficiency gains of a rollout-based approach for organisations growing through M&A.
It depends on how standardised your operations already are. Organisations with consistent operations across entities generally benefit from a single 1-tier instance; those with regulated subsidiaries, acquired entities needing operational autonomy, or highly distinct regional operations often do better with a 2-tier model connected through SAP Integration Suite.
