Advisory Assistant

At JOINSON&SPICE, we work with leading tech companies and strongly believe in a data-driven approach, using our in-house developed software to deliver outstanding results. Innovation really does literally flow through our veins. Our team is growing (we aim to triple in size by 2028), and we work with fast-growing scale-up clients in Tech, both national and international who need more than just compliance — they need Advisory Assistants who think with them.

🧩 Your Day

Your day starts with a coffee or tea and a quick team check-in. Together, you go over the planning and your tasks for the day. You’ll be supporting the advisory team with a variety of activities, helping to keep client work organized and on track.

In the morning, you work on updating client files and processing financial data, such as purchase and sales entries. You make sure everything is correctly recorded and well-structured. As you go, you start to recognize how financial information fits together and supports the bigger picture.

Mid-morning, you assist a colleague with preparing a VAT return or gathering documentation for a year-end process. You help ensure all required information is complete and ready to use. When something is unclear or missing, you check in with your team to move things forward.

After lunch, you continue with your tasks—working in tools like CaseWare, updating documentation, and preparing simple overviews or reports. You receive feedback from colleagues and use it to improve your work and build your skills step by step.

Throughout the day, you stay in touch with your team, ask questions, and support where needed. You’re learning how advisory work comes together, while contributing to accurate and well-organized client files.

At the end of the day, you close your laptop knowing you’ve supported the team and made progress. With each task, you’re building your knowledge, confidence, and experience in advisory.
