Our Services
Each service starts with a finance outcome, then the SAP work that delivers it. We work on our own or alongside your integrator, as the SAP DRC and Finance specialists.
SAP DRC & Tax Compliance
Keep invoicing without interruption when e-invoicing and tax reporting become mandatory. We implement SAP Document and Reporting Compliance on clean master data, designed to reduce rejection risk.
- Valid invoices in every country: local and cross-border e-invoicing
- Returns filed on time: real-time legal and tax reporting
- Fewer rejections: a master data audit before go-live
S/4HANA Finance Optimization
A faster close and figures management can rely on. We redesign your accounting structures in S/4HANA Finance: ledgers, FI/CO and the close process.
- Local GAAP and IFRS side by side: leading and parallel ledger design
- Fewer days to close: Fast Close acceleration
- Margins and costs you can explain: FI/CO structure and analytics
Evolution and Advisory
Finance decisions that hold up in SAP. We work with CFOs and CIOs as a trusted counterpart between the business and the technology.
- Cash collected and suppliers paid on time: Order-to-Cash and Procure-to-Pay
- Cash and group results in one view: treasury and consolidation
- Cost control the business actually uses: management accounting (CO)
- SAP that keeps up with the strategy: tailored enhancements

Maricel Campos
Co-Founder & Chief of Staff

Our team
Beyond the founders
A growing team of SAP specialists, shaping this firm and the success of your project.
Most e-invoicing projects don't fail on the format. They fail on the master data.
SAP DRC takes care of the format. What the tax authority rejects is a missing VAT ID, an incomplete address or a wrongly mapped tax code. We get your SAP data ready before that happens.
It is our specialty, and the first step of every DRC project we run.
What we check
VAT and tax IDs, addresses, tax codes and the routing IDs each mandate needs (Peppol, SIREN), for every company code, customer and supplier.
How we do it
We profile the data in your own SAP system, rank each gap by the invoices it would block, and fix it at source, not in the output.
Keep it clean
Validation rules at creation, so a new customer or supplier can't break your compliance next month.
What you get
A gap list by country and entity, and a cleansing plan with owners and dates.
The 60-minute diagnostic: you leave with your gaps written down
A working session with the founder, not a sales pitch. By the end you have four things in writing:
Your top risks
What could stop you invoicing or reporting on time, ranked by impact.
Master-data gaps
Where your customer, supplier and tax data would be rejected, and where to start.
Your mandates
Which country mandates apply to which of your entities, and from when.
Next SAP actions
What to do in SAP, in what order, and whether your release supports it.
What to bring
A list of your legal entities and the countries they invoice in, your SAP release, and any deadlines you already know about.

E-invoicing and SAP DRC
Led the SAP DRC delivery for France (Chorus Pro) and Germany within an international technology group's global program: eDocuments, AIF and Peppol/BTP.
S/4HANA Finance and FI/CO
Functional SME on a Lift & Shift project (FI-AR / FI-AP) for an international commodity-trading client, plus end-to-end leadership of SAP RE-FX projects.
Delivery leadership
Over a decade leading functional and technical teams as Scrum Master and single point of contact for client leadership. PRINCE2, CSM/CSPO and ITIL4 certified.
We take over your developments, whether we built them or another provider did.
Your integrator has moved on, or the person who built it has left. Before we take responsibility for existing code, we run a handover assessment, so nothing is inherited blind.
After that, we keep your SAP DRC and Finance developments running and up to date: incidents, change requests and updates whenever a mandate changes.
And we don't just react. Every month you get a report of the tickets handled, the recurring problems worth fixing at the root and the regulatory changes coming up, and we plan the work ahead of each deadline. You can contract it as a monthly bag of hours, a fixed monthly fee or time and materials, and escalate any ticket straight to the founder.
Inventory
Every custom object in scope: programs, enhancements, interfaces, DRC settings and forms.
Documentation and risks
What is documented and what isn't, and which pieces are fragile or out of step with current mandates.
Access and transports
Systems, roles and the transport path we will use, agreed with your Basis team.
Runbook
A short guide per development: what it does, how to check it and what to do when it fails. It is yours to keep.

Frequently Asked Questions
Resolving your core questions before scheduling an initial diagnostic call.
The timeline depends on country scope and transactional complexity. A focused implementation for a local mandate (such as B2B e-invoicing or local reporting) typically takes 6 to 12 weeks. Thanks to our direct, streamlined approach, we eliminate weeks of theoretical design and focus straight on configuration, testing, and Go-Live.
Absolutely. We frequently act as boutique specialist advisors for executive leadership (CFO/CIO Advisory). We integrate seamlessly with your internal team or primary IT partner to specifically lead accounting architecture and tax compliance (DRC), bringing specialized technical depth to the project.
SAP DRC requires strict data consistency to prevent rejection by tax authorities (VAT IDs, addresses, tax classifications). We conduct a master data readiness audit early in the project to identify gaps and build validation rules prior to deployment.
We don't hand over and disappear post-Go-Live. We provide hypercare support and continuous monitoring during your first tax filings. Furthermore, we accompany your team through future legislative updates to ensure your ERP stays compliant without rebuilding the core.
