About Onshore

Onshore is transforming how businesses identify and claim valuable tax incentives. We combine technology, automation, and exceptional customer service to make a traditionally complex process simple for our clients. We're growing quickly, and we're looking for people who thrive in fast-paced environments, enjoy solving problems, and genuinely care about helping customers.

The Opportunity

We're looking for an Accounts Receivable Manager who is much more than a collections professional. This role owns the customer billing and collections experience while building strong customer relationships. The ideal candidate is friendly, confident, organized, comfortable picking up the phone, and always looking for better ways to solve problems and improve processes.

Key Responsibilities

• Own the end-to-end Accounts Receivable process from invoicing through payment.
• Manage billing, collections, and customer payment communications.
• Build strong customer relationships while maintaining timely collections.
• Partner with Customer Success, Sales, and Finance to resolve billing issues.
• Monitor aging reports and reduce DSO.
• Investigate payment delays and resolve disputes professionally.
• Coordinate ACH, wire, and check payments.
• Maintain accurate AR records and reporting.
• Assist with month-end close and audit requests.
• Identify automation and process improvements.
• Build scalable AR processes as Onshore grows.

Qualifications

• 5+ years in Accounts Receivable, Billing, or Credit & Collections.
• Strong B2B collections experience.
• Excellent verbal and written communication skills.
• Comfortable speaking with customers daily.
• Strong problem-solving skills and business judgment.
• Highly organized and detail-oriented.
• Startup mindset with ownership mentality.
• Experience with QuickBooks, NetSuite, Salesforce, or similar systems preferred.

Who You Are

• Friendly and relationship-oriented.
• Customer-first communicator.
• Thinks outside the box and applies common sense.
• Takes ownership and follows through.
• Process builder, not just a process follower.
• Positive, proactive, and collaborative.
• Comfortable in a fast-paced, high-growth environment.

Success in the First 12 Months

• Improve collections efficiency and reduce DSO.
• Strengthen customer relationships while accelerating cash collections.
• Implement scalable billing and collections processes.
• Introduce automation and continuous process improvements.
• Become a trusted partner across Finance, Sales, and Customer Success.
