Boekhouder / Bookkeeper

Your Mission

We are looking for an experienced and detail-oriented Bookkeeper to strengthen our Finance team and help us bring more of our day-to-day financial administration in-house.

Based primarily at our Elst (Gelderland) office, you will be responsible for accurate and reliable bookkeeping across our Dutch and German operations. This is a hands-on role for someone who genuinely enjoys financial administration, takes pride in getting the details right, and is comfortable managing the day-to-day books independently.

Key Responsibilities:

• Maintain accurate and up-to-date day-to-day bookkeeping and general ledger administration.
• Process purchase and sales invoices, expense claims and journal entries.
• Manage accounts payable and accounts receivable, including payment runs and outstanding balances.
• Reconcile bank accounts, balance-sheet accounts and subledgers, investigating and resolving discrepancies where necessary.
• Support month-end closing activities and help maintain reliable financial reporting.
• Prepare and support Dutch VAT returns and other routine financial reporting requirements, including CBS reporting.
• Maintain the financial administration for our Dutch and German entities in cooperation with colleagues and external advisers.
• Ensure transactions are accurately coded, documented and processed in line with internal controls and local requirements.
• Follow up with colleagues on missing information, approvals or documentation.
• Identify practical opportunities to improve the quality and efficiency of our financial administration.

Your Profile

• Several years of hands-on experience in bookkeeping, financial administration or a similar role.
• A relevant financial qualification such an MBO+/HBO degree in Finance, Accounting, Business Administration or equivalent practical experience.
• Strong practical understanding of general ledger bookkeeping, journal entries, AP/AR and reconciliations.
• Experience with Dutch financial administration is required.
• Experience with German bookkeeping or financial administration is an advantage, but specialist German tax knowledge is not required.
• Experience supporting VAT administration and month-end activities.
• Fluent Dutch and professional working proficiency in English. German language skills are an advantage.
• Accurate, structured and highly detail-oriented in your work.
• Reliable and discreet when handling confidential financial information.
• Comfortable working independently, meeting deadlines and taking ownership of your responsibilities.
• Hands-on, pragmatic and solution-oriented.
• You enjoy bookkeeping and financial administration and are looking for a role where you can develop strong knowledge of the organisation and provide reliable long-term support to the Finance team.
