Business Controller (full-time, Amsterdam)

About Wundermart.

Wundermart builds and operates 300+ unmanned lobby shops in hotels across Europe. We're a fast-growing company active in the Netherlands, Belgium, Germany, France, Poland, Austria, Spain, the Czech Republic, and the UK - and we're just getting started. Our finance team plays a central role in fuelling that growth and is located in Amsterdam.

Your Role.

As our new Business Controller, you'll be the go-to finance partner for our commercial teams responsible for new shop openings and account management. You'll translate numbers into insights — for our internal teams and for the hotel partners we work with.
You'll work closely with the Commercial Director to set the annual sales budget and keep the forecast sharp throughout the year. As owner of project administration, you'll collaborate with project managers to monitor investments and track financial performance of new openings from day one.
Data drives smart decisions at Wundermart, and you'll make sure the right reports reach the right people at the right time. You'll oversee other income streams — license fees, rebates, and more — and help automate and improve processes like our Adyen reconciliation, working hand in hand with our in-house tech team.
Most importantly, you bring a continuous improvement mindset. You'll help design and implement scalable financial processes that can grow with us. If you're the type who spots an inefficiency and immediately wants to fix it — you'll fit right in.

What You'll Do.

• Report and analyse monthly shop financial results and share insights with internal stakeholders including the management.
• Support and advise the commercial team on financial matters related to new openings and new business development.
• Own project administration for new shop openings, monitoring investments and financial performance.
• Build and maintain periodic and ad hoc reports to support data-driven decision-making.
• Control other income streams and commercial incentives.
• Drive automation and process improvement initiatives, including Adyen reconciliation.
• Collaborate with Data analytics and the Commercial Director on annual budgeting and regular reforecasting.
• Design and implement scalable financial processes to support future growth.

What You Bring.

• A degree in Finance or Accounting (HBO, BSc, or MSc).
• At least 3 years of relevant experience in a similar finance role.
• Strong analytical skills combined with a hands-on, get-things-done attitude.
• A genuine drive to continuously improve processes and challenge the status quo.
• Solid Excel skills, formulas, models, and data manipulation are second nature to you.
• Fluency in English (written and spoken); Dutch, German, and/or French is a plus.
• Comfort working in a fast-paced, entrepreneurial environment where no two days are the same.

What We Offer.

• A pivotal role in a fast-growing European retail tech company.
• Direct impact on commercial performance and strategic decisions.
• A collaborative, ambitious team that values curiosity and initiative.
• Room to grow as the company scales across Europe.
• Salary range: €3.750 – €4.000 gross/ month, based on experience.
• Learning budget

• Monthly phone compensation
• Regular company events
• And more...
