Accounts Receivable & Billing Specialist - Belgrade

Sedona Digital is a rapidly growing scale-up organisation specialising in software, data, cloud, and security transformation. We partner with enterprise clients to solve complex challenges, delivering modern technology solutions that drive long-term value.

We are looking for an Accounts Receivable & Billing Specialist to take ownership of complex billing and discount application across our global client base.

This is not a traditional AR role. You will sit at the centre of our order-to-cash process, ensuring that invoices are accurate, aligned to contractual terms, and reflective of agreed commercial arrangements.

You will play a key role in protecting revenue, improving billing accuracy, and enabling scalable growth.

Responsibilities

• Generate accurate invoices based on timesheets, delivery data, contracts, and milestones
• Manage complex billing scenarios across multiple entities, currencies, and client structures
• Apply contractual and approved discounts accurately
• Validate rate cards, pricing structures, and alignment to agreed commercial terms
• Identify and flag inconsistencies in discounting and potential revenue leakage
• Ensure alignment between sales agreements, delivery outputs, and billing data
• Maintain clear audit trails for invoices, adjustments, and discounts
• Prevent underbilling, overbilling, and revenue leakage
• Collaborate with finance, delivery, and sales teams to ensure billing accuracy and completeness

Additional Information

At Sedona Digital, we value integrity, persistence, and impact. We are looking for individuals who take ownership, are committed to continuous improvement, and want to contribute to building a high-performance organisation.

If you enjoy working at the intersection of finance, operations, and commercial delivery, and want to play a meaningful role in scaling a growing business, we encourage you to apply.
