About Nooks.ai:

Nooks is an applied AI lab building the Agent Workspace for GTM. We design AI agents that operate across the full sales action set, from account strategy to prospect research and outreach. Building 0→1 has never been easier, but selling at the speed of the market remains the last frontier for AI. Our mission is to 10x every seller by automating the busywork so they can focus on what humans do best: closing deals.

Today, over 1,500 customers run on Nooks, including Notion, HubSpot, Cursor, and Rippling. We’ve raised $70M+ from top VCs like Kleiner Perkins, which made its first sales-tech investment in over a decade with us. Since then, we’ve tripled ARR each year for 3 years running and grown a high-caliber team turning the art of sales into a scalable science.

About the Role:

This is a great opportunity to join Nooks' growing Finance team and play a critical role in our revenue accounting and operations function. Reporting directly to the Senior Accounting Manager, the Accounts Receivable Analyst will be a key player in ensuring our billing, collection, and cash reconciliation workflows are timely, accurate, and seamless.

You'll be at the forefront of modern accounting practices, working with AI tools and systems automation. This role is perfect for someone with an "in the weeds" mentality who is ready to tackle daily cash application tasks, resolve billing disputes, own AR balance sheet reconciliations, and help build scalable processes for our next phase of rapid growth.

Working Hours:

This role requires flexibility to collaborate across Central European and Pacific Time zones.

Core Responsibilities:

• Billing & Invoicing Execution: Assist with the end-to-end billing cycle by preparing and auditing invoices against contracts, MSAs, and Purchase Orders (POs), while submitting invoices and tracking payment approvals directly through customer procurement portals (e.g., Coupa, SAP Ariba, Taulia) to prevent payment holds.

• Collections & Aging Management: Proactively manage AR aging schedules and conduct firm, professional outreach to resolve payment delays, and designing payment workout strategies for high-risk clients and managing legal or third-party collection escalations to optimize DSO.

• Tech-Forward Reporting & Communication: Utilize modern software tools to design clear collections dashboards, deliver structured weekly AR updates to direct managers, and maintain transparent, proactive communication across Sales and Finance to keep cash flow metrics visible.

• Discrepancy & Dispute Resolution: Partner with Sales, Customer Success, and Finance to investigate short payments, billing disputes, unapplied cash, and process valid credit memos or adjustments.

• Cross-departmental Collaboration: Partner with cross-functional leaders to optimize customer onboarding, billing workflows, and internal revenue controls.

• Audit Support & Documentation: Maintain clean, well-organized AR documentation on an ongoing basis, and assist during annual external audits by gathering the relevant supporting documents.

What You Bring to the Table:

• 2-3+ years of dedicated accounting experience focused on accounts receivable, billing, and cash reconciliations, preferably in SaaS or a high-growth environment.

• Experience with ERP systems (QuickBooks, NetSuite, or similar) and billing tools, with a strong aptitude for learning new systems.

• Familiarity navigating customer procurement portals (Coupa, SAP Ariba, etc.) and handling complex PO structures is a plus.

• Fluent in English.

• Excellent attention to detail and strong problem-solving skills.

• A proactive team player with an "in the weeds" mentality and a willingness to roll up their sleeves to build scalable processes
