About the role

We are looking for a precise, structured and proactive Accounts Payable Accountant to take ownership of our accounts payable process across our Belgian and Dutch entities.

This is a full-time role with a high degree of autonomy, trust and flexibility. The position can be performed largely remotely, provided that communication is clear, availability is predictable and key finance processes remain well controlled.

You will play an important role in keeping our purchase-to-pay flow accurate, timely and reliable. Your work directly impacts supplier payments, financial closing, reporting quality, cash visibility and the overall efficiency of the finance team.

Your responsibilities

You will be responsible for the day-to-day management of the AP process and related finance administration.

Your main responsibilities include:

• Processing and following up purchase invoices in Blue10 & ExactOnline.
• Ensuring invoices are routed to the correct approvers, owners and approval flows.
• Monitoring open, blocked or unclear invoices and resolving bottlenecks proactively.
• Managing the finance mailboxes for Belgium and the Netherlands.
• Processing bank transactions and matching payments correctly with invoices.
• Reconciling customer accounts, including payments, invoices and credit notes.
• Reviewing and cleaning up supplier balances, including open items, duplicates, credit notes and unclear positions.
• Booking invoices on the correct legal entity, general ledger account and cost center.
• Supporting monthly, quarterly and yearly closings by ensuring AP items are processed before the agreed deadlines.
• Preparing a short weekly AP status update, including backlog status, blockers, required actions and expected timing.
• Escalating issues in a timely and constructive way when clarification, decisions or support are needed.

What we are looking for

We are looking for someone who combines accuracy with ownership. You understand that accounts payable is not just administration, but an important part of a reliable and well-run finance operation.

You are someone who:

• Has relevant experience in accounts payable, accounting or finance administration.
• Works accurately and consistently, with strong attention to detail.
• Is comfortable working independently in a remote or hybrid setting.
• Communicates clearly, proactively and professionally.
• Follows up open items until they are resolved.
• Is organised, deadline-conscious and able to manage recurring processes.
• Understands the importance of correct coding, reconciliations and clean supplier balances.
• Knows when to ask questions, escalate issues or challenge unclear information.
• Is confident working with digital finance tools and approval workflows.
• Takes initiative to improve structure, control and efficiency in day-to-day processes.

Experience with Blue10, ExactOnline and Teamleader or similar finance and workflow tools is a strong plus.

What we offer

At Customer Collective, you will join a dynamic and entrepreneurial environment where collaboration, ownership and continuous improvement are part of everyday work.

We offer:

• A full-time role within a growing marketing and technology consultancy platform.
• A high level of autonomy and trust.
• The possibility to work largely remotely.
• Flexible working arrangements, with clear alignment and communication.
• A role with visible impact on the quality and reliability of our finance processes.
• Collaboration with experienced professionals across finance, strategy, digital, data, technology, creative and performance marketing.
• The opportunity to help further professionalise our AP, closing and finance operations.

Why this role matters

This role is essential to keeping our finance operations stable, predictable and accurate.

When invoices are processed correctly and on time, suppliers are paid reliably, closing runs more smoothly, reporting becomes more accurate and the finance team can operate with greater confidence.

We are therefore looking for someone who brings not only technical accuracy, but also ownership, structure and pride in well-run financial processes.
