Our SAP Services
S/4HANA Readiness Check
We analyze your ECC system and assess migration readiness. SAP Readiness Check, Custom Code Analysis, honest effort estimate.
Migration Path Advisory
Brownfield, greenfield, or hybrid? We evaluate all three paths against your system landscape, budget, and timeline. Including risk assessment.
Asset Accounting Migration (FI-AA)
In S/4HANA, asset accounting merges with the general ledger. We migrate your FI-AA master data, adjust valuation areas, and convert depreciation runs.
CO-PA Conversion
From parallel profitability analyses (account-based + costing-based) to a unified model in S/4HANA. Properly migrated, not just technically converted.
Business Partner Migration
Customers and vendors become Business Partners. Sounds simple, usually fails due to data quality. We cleanse before migration, not during.
General Ledger Migration (New GL)
S/4HANA requires the New General Ledger. Companies still on the classic GL need this step first. We have been doing this for years.
FI/CO Customizing
Our consultants configure SAP FI and CO themselves. Chart of accounts, company codes, controlling areas, operating concerns. Hands-on, not just slides.
E-Invoicing (XRechnung / ZUGFeRD)
Mandatory for B2B in Germany since 2025. We configure electronic invoice output in SAP and ensure XRechnung and ZUGFeRD compliance.
Intercompany Settlement
Intragroup service allocation, transfer pricing, IC reconciliation. We configure your intercompany processes in FI/CO so month-end close runs without manual effort.
Master Data Cleansing & Harmonization
Clean up charts of accounts, harmonize cost centers, restructure profit center hierarchies. Before your S/4HANA migration or as a standalone project.
FI/CO Team Augmentation
Your project team needs reinforcement in Finance or Controlling? We provide complete FI/CO teams or individual specialists. Two weeks lead time.
Interim Management
Individual consultants for transitional phases, special projects, or vacancies. Each one can lead projects independently, productive from day one. No ramp-up.
Sub-Contracting
Consulting firms such as valantic, PwC, and BearingPoint rely on our FI/CO specialists for complex S/4HANA transformations. Deep module expertise meets professional presence.
Contracting
Flexible engagement models for defined work packages or longer project phases. You set the framework and duration, we deliver the expertise.
AI-Enhanced SAP Processes
Anomaly detection in postings, automated account assignment, cash flow forecasting. We bring AI capability into your SAP landscape, starting with your first project.
Our Approach
How your SAP transformation works
Four phases proven across our migration projects. Not a rigid methodology, but a framework we adapt to your system landscape.
02
Migration Path & Planning
Detailed planning for the chosen path. Scope definition, resource planning, milestones. Because most projects fail on master data, not on technology.
03
Implementation & Testing
ACDOCA migration, Business Partner conversion, CO-PA merge, New GL. Every workstream with dedicated FI/CO specialists. Testing with AI-powered data validation.
04
Go-Live & Stabilization
Cutover management, hypercare phase, end-user training. We stay until the system runs stable. Not until the contract ends.
The Competence Triangle
Three sides. No compromise.
Every rwQUANTICAL consultant is assessed against our competence triangle: communication, domain expertise, technical skill. All three sides must hold. Other consultancies train their SAP consultants on live projects. Ours come from the field and are tested on both knowledge and skill before their first engagement.
The result: consultants who can engage business stakeholders, understand FI/CO processes from practice, and customize the system themselves when needed. Every single one can lead projects independently. This triangle is also part of our logo. It is not a slogan, it is our selection principle.
“We do not sell consultants who need onboarding. We provide experts who deliver from day one.”
SAP meets AI
Why SAP consulting without AI capability is no longer enough.
S/4HANA delivers a unified real-time data model for the first time. This makes SAP the foundation for AI applications in finance: anomaly detection, automated account assignment, predictive cash flow planning.
rwQUANTICAL is one of the few consultancies that combines both: deep SAP FI/CO expertise and in-house AI development capability. In our migration projects, we already deploy AI during the testing phase. Models validate migrated data against historical patterns and find inconsistencies that rule-based checks miss.
The SAP Market in Numbers
Why now is the right time
88% of SAP customers plan the S/4HANA migration. At the same time, thousands of FI/CO specialists are missing. Those who start early get to choose. Those who wait take what is left.

Common Questions
FAQ on SAP Consulting
What does SAP consulting cost at rwQUANTICAL?
Our day rates are in the standard range for specialized SAP FI/CO consulting. A pre-study or readiness check typically starts in the five-figure range. Full S/4HANA migration projects range from €250,000 to €1.2 million depending on complexity. We offer a free initial consultation for a realistic estimate.
Brownfield or greenfield: which fits better?
Brownfield is faster (6-12 months) and cheaper, but you migrate technical debt along with it. Greenfield is more expensive (12-24 months) but gives you a clean system. In about 40% of our projects we recommend the hybrid approach: keep master data, leave legacy behind. The decision depends on your system landscape, not on a philosophy.
How long does an S/4HANA migration take?
Plan for 3-6 months for the pre-study and 6-24 months for the actual migration, depending on path and complexity. Brownfield at the lower end, greenfield at the upper. Add a stabilization phase of 2-3 months after go-live.
What changes in FI/CO with S/4HANA?
Three fundamental changes: First, the ACDOCA table replaces over 20 separate FI and CO tables. Second, account-based and costing-based profitability analysis merge into one. Third, customers and vendors become Business Partners. These changes affect every accountant and every controller in your organization.
What sets rwQUANTICAL apart from other SAP consultancies?
Our competence triangle: every consultant must excel in communication, domain expertise, and technical skill. While other consultancies train junior consultants on projects, we only hire experts who work independently from day one. On top of that, we bring AI capability: we already use machine learning during the testing phase of migrations.
Do you also work as a sub-contractor for other consultancies?
Yes. Consulting firms such as valantic, PwC, and BearingPoint rely on our FI/CO specialists for complex S/4HANA transformations. We bring module expertise and a professional presence that matches the level of these projects.
When does SAP ECC maintenance end?
Standard maintenance for SAP ECC 6.0 ends in 2027. Extended maintenance runs until 2030 at a 2% surcharge on license fees. After that: no patches, no security updates, no support. Companies starting in 2028 will reach go-live in 2030 at the earliest. Without buffer.
How does rwQUANTICAL integrate AI into SAP projects?
During the testing phase, AI models validate migrated data against historical patterns and find inconsistencies that rule-based checks miss. After go-live, the ACDOCA data model enables AI applications such as automated account assignment, anomaly detection, and cash flow forecasting.
Do you also support e-invoicing?
Yes. E-invoicing has been mandatory for B2B transactions in Germany since 2025. We configure electronic invoice output and receipt in SAP and ensure XRechnung and ZUGFeRD compliance. For running systems we integrate this retroactively; for migration projects it is included from the start.
