Financial processes · Systems · Controls
Reliable numbers — through sound financial processes, systems and controls.
Over 17 years in finance — audit at Deloitte, Head of Finance, ERP migrations. I bring structure to financial processes, systems and internal controls — as an external partner, in clearly defined packages, step by step, each with a results report. Remote, with no ongoing costs.
Services
Where I come in
Controlling, finance and the systems behind them — from analysis to implementation. System-agnostic and remote.
Controlling & Reporting
Management and investor reporting, planning, forecasting and KPIs — transparency as the basis for sound decisions.
Finance & Statements
Bringing order and stability to financial processes, preparing financial statements — HGB, IFRS and US GAAP, clean and audit-proof.
Processes & Systems
Analysing, optimising and digitalising workflows — system-agnostic, from DATEV to SAP. In system migrations I validate the data on the finance side: that balances, statements and controls carry over correctly and stay audit-proof.
Analysis, Documentation & Handover
Current-state analysis, results reports, work aids and training — so your team can carry on independently and a permanent role becomes viable to fill again.
Experienced across common ERP and finance systems — incl. SAP HANA, Oracle NetSuite, Microsoft Dynamics, DATEV (incl. DATEV Unternehmen online) and Agenda. I get up to speed with your system landscape quickly — whatever you run. Experienced across corporates, SMEs and start-ups — familiar with how each operates.
Profile
Over 17 years in finance — from Big Four audit to heading up finance
Audit, controlling and building and reworking finance processes: with a background in audit at Deloitte, in manager and head-of-finance roles, and in ERP projects for technology, e-commerce and industrial companies.
Seniority & track record
From Big Four audit (Deloitte) through manager and head-of-finance roles to project mandates — 17+ years across a range of industries.
HGB · IFRS · US GAAP
Financial statements and reporting logic across all three standards — including reconciliations and cross-border comparability.
Controls & governance
Internal control systems (ICS/SOX) and building an ISMS to ISO 27001 certification — structure and reliability in complex financial setups.
Finance meets systems
ERP migrations and data structures (SAP, NetSuite, Dynamics, DATEV) — spotting structural issues in financial data and tracing them back to the underlying process or system.

How I work
Clearly scoped packages instead of constant availability
You don't need to arrive with a finished plan. Gaining an overview and turning it into clearly defined, prioritised steps is already part of my work. I then drive each step forward and deliver; you won't have to follow up.
The five questions that decide it — instead of quick fixes:
- What's actually keeping you up at night?
- What's it costing you right now?
- How does the process run today — and where can it be improved?
- Which best practice applies here?
- Which steps are possible — and which do we take first?
Assessment
I get a picture of your processes and work out what really needs doing — and how urgent it is. You receive a results report with recommendations and a clear order of priority for the next steps.
Implementation
A follow-up offer for the first concrete step — you accept it, raise different priorities or stop. Communication runs through one central email address, without endless calls.
Adapt & continue
Depending on what emerges, the plan stays or is adjusted. A new offer follows for the next step. The work proceeds step by step, all documented.
It's not about availability — it's about results. The difference:
This way — my approach
- Every step ends with a results report — not just presence
- Start small, stop any time — a fixed price per step, nothing to pay in between
- Adapts: if requirements change, the next package changes with them
- Direct, not via a middleman — exactly the right expertise, no agency margin
- Documented and traceable through closed steps
- Independent and remote in the background, delivered on time — keeping your daily business clear, no constant calls
Not this way — buying availability
- Lots of activity, little solved — the problem is postponed, not fixed
- A fixed monthly budget runs whether you use it or not — with a bought-in interim role, quickly into five figures
- Often via a provider in between — focused on a fast placement, less on the exact match
- A fixed block of hours, no matter how requirements change
- Little documented in the end — hard to keep gapless when requirements keep changing
- You keep having to feed and steer the work — the scope stays unclear
- Costs of on-site presence — desk, travel time and expenses
For companies looking to bring order to, migrate or stabilise their controlling and financial processes.
For example when a finance role departs, ahead of a year-end close, when migrating systems, or when many isolated tools need to become one clean process — without creating a permanent position.

What clients say
Demiana impressed me with how quickly she was able to dive into complex finance processes and understand the underlying data flows and reporting structures within a SAP-based environment. She has a natural ability to spot inconsistencies and get to the root of issues … she focuses on building sustainable solutions that bring clarity, stability, and long-term value to processes and systems … I would gladly work with her again and can highly recommend her to any team looking for strong expertise in finance processes, systems, and controls.

I have worked on several projects with both Demiana herself as well as her team. I can fully and wholeheartedly recommend her to anyone looking for temporary or long-term Finance support. The quality of the work is outstanding and everything is delivered as agreed (both in terms of output and timing). Prices are very fair and she will make sure that scoping is done right, so that there won't be any surprises.
