The role works closely with Finance, Sales, Customer Success and Operations to ensure customers are billed correctly, payments are applied accurately and past-due accounts are resolved without damaging relationships.

Key responsibilities

• Generate accurate, timely invoices based on contracts, order forms and service agreements.
• Manage the end-to-end order-to-cash cycle, maintain aging schedules and reconcile customer accounts.
• Post and allocate daily incoming payments (ACH, wires, checks, credit cards) to customer accounts.
• Investigate, document and resolve billing discrepancies, short payments and customer deductions.
• Lead proactive B2B collections outreach to past-due accounts and secure payment while protecting relationships.
• Structure reasonable payment plans and settlement agreements for delinquent accounts.
• Analyze AR aging reports to prioritize collection efforts across 30, 60 and 90+ day buckets.
• Identify billing-cycle bottlenecks and work with Sales, Customer Success and Finance to fix systemic billing errors.
• Maintain internal controls and documentation in line with GAAP and audit requirements.

Required profile

• Experience in billing, accounts receivable and collections, ideally in a B2B or SaaS environment.
• Fluent English and clear, professional written and verbal communication with internal and external stakeholders.
• Ability to negotiate payment plans and handle difficult financial conversations with tact and empathy.
• Attention to detail, strong time management and comfort in a fast-paced startup where processes are still being built.

Required skills

• Working knowledge of GAAP, internal audit controls and fair debt collection practices.
• Hands-on experience with an ERP or accounting system such as NetSuite, QuickBooks, SAP, Oracle or Sage, and billing platforms.
• Nice to have: subscription or recurring revenue billing, automation or AI tools for billing and collections, and familiarity with US billing and collections practices.

What we offer

• Pre-IPO equity.
• Performance bonus.
• Work alongside industry experts and leaders in multifamily.
