What it’s like to work at Topsort

At Topsort, we communicate openly and move fast. We say things as they are, challenge each other early, and embrace feedback with curiosity—it’s how we build better, faster. Every experiment has a purpose, and every outcome helps us make the next decision smarter. There’s no single formula for success here; we find what works, improve it, and scale it.

We’re collaborative internally and competitive externally—never the other way around. The pace is quick, sometimes a 100-mph kind of fast, and that’s what keeps it exciting. We act with intent, lift each other up, and turn bold ideas into real results. No endless meetings here—if it can be done today, it gets done today.

What Is This Role Like?

We’re looking for a sharp, execution-driven Billing Manager to own and scale global billing and collections at Topsort.

In this role, you will:

• Billing Operations Ownership: Own end-to-end billing processes across multiple entities and regions, ensuring accurate, timely, and consistent invoicing aligned with contractual terms.
• Collections & Cash Flow Management: Lead the collections process, proactively managing outstanding invoices, reducing DSO, and serving as the primary point of contact for all billing and payment-related client inquiries.
• Systems & Process Optimization: Optimize billing systems (e.g., NetSuite, Sequence) and workflows to improve efficiency, reduce errors, and build scalable processes that support company growth.
• Compliance & Local Regulations: Ensure all invoicing complies with local tax regulations and fiscal requirements across jurisdictions, balancing standardization with country-specific requirements.
• Issue Resolution: Identify and resolve billing discrepancies proactively, partnering with Finance, Sales, and Customer Success to address disputes efficiently and maintain client trust.
• Cross-Functional Collaboration: Collaborate closely with Finance, Sales, Customer Success, and Legal teams to ensure accurate billing, contract alignment, and smooth revenue operations.
• Reporting & Insights: Provide clear visibility into billing performance, collections status, and potential risks, enabling stronger financial decision-making and operational planning.

What We Think You Need to Be Successful - We’re open to candidates who don’t check every box but show strong potential.

Core Requirements & Experience:

• Experience: 2+ years of experience in billing, revenue operations, or accounting, ideally in multi-entity, multi-country environments.
• Billing Expertise: Strong understanding of end-to-end billing cycles, collections, reconciliation, and revenue operations in complex setups.
• Global Exposure: Experience working across US, LATAM (including Brazil), APAC, or EMEA, with solid knowledge of local tax regulations and invoicing requirements.
• Systems & Tools: Hands-on experience with billing systems such as NetSuite, Sequence, or similar tools, with a focus on optimization and scalability.
• Process Building: Proven ability to build, standardize, and improve billing processes in fast-paced, high-growth environments.
• Stakeholder Management: Strong communication and structured thinking, with the ability to partner effectively with clients, sales teams, and finance leaders.
• Detail & Ownership: Highly detail-oriented, reliable, and accountable — you take full ownership and don’t let things fall through the cracks.
• Language Skills: Full professional proficiency in English, plus Spanish or Portuguese.
• Agility & Mindset: Comfortable operating in ambiguity, with a hands-on, problem-solving attitude and a strong drive to improve systems and processes.
• Collaboration: Team-oriented, curious, and eager to learn, with the ability to thrive in a global, remote-friendly, and fast-evolving environment.
