The ideal candidate has experience in SaaS accounting, particularly revenue recognition and subscription billing, and is comfortable working cross-functionally to develop scalable, efficient financial processes. This role requires a mix of hands-on execution and strategic oversight, ensuring accounting policies and practices align with both business needs and compliance requirements.

While we are headquartered in Austin, Texas, this position is open to candidates in Dallas as well. For local candidates, we offer a hybrid office arrangement with flexible hours.

What you’ll do:

General Accounting & Compliance:

• Support the monthly and quarterly close process, including journal entries, reconciliations, and variance analysis.

• Assist in preparing and reviewing financial statements in accordance with GAAP and ASC 606.

• Collaborate with auditors during financial audits and tax filings.

Revenue & Order-to-Cash Management:

• Oversee and optimize the order-to-cash process, ensuring accurate revenue accounting and collections.

• Manage subscription billing cycles, contract changes, proration, and adjustments.

• Work cross-functionally with Sales, Customer Success, RevOps, and Engineering to improve invoicing and payment processes.

• Act as a key point of contact for revenue-related customer inquiries, collections, and issue resolution.

Systems & Process Improvement:

• Leverage and optimize accounting, ERP, and billing systems (e.g., NetSuite, Zuora, Chargebee).

• Identify opportunities for automation and process improvements to enhance accuracy and efficiency.

• Provide recommendations for system enhancements and financial controls.

Billing Operations:

• Generate, review, and ensure accuracy of customer invoices.

• Manage subscription billing cycles, proration, and adjustments in line with contract terms.

Customer Support:

• Resolve billing tickets and address customer inquiries promptly and professionally.

• Collect outstanding receivables, as needed.

• Act as a liaison between customers and internal teams to address complex issues.

Who you are

• Bachelor’s degree in Accounting, Finance, or a related field.

• 5-10 years of experience in accounting operations in a SaaS environment.

• Strong understanding of revenue recognition principles (e.g., ASC 606).

• Proficiency in accounting and billing systems (e.g., NetSuite, Zuora, Chargebee). Zuora is preferred, but not required.

• CPA is required.

• Excellent problem-solving and communication skills.

We hire for potential, passion for our mission, and a knack for solving difficult problems over checking every qualification box. We have competitive pay, equity with significant upside, and intentionally design our benefits to encourage healthy and well-balanced employees, from flexible work schedules to unlimited paid time off. We even offer a sabbatical after every five years of service so you’re able to pursue and enjoy what matters most to you. And of course, we wouldn’t be a technology company in Austin without a ping-pong table and free snacks in our break room. Join us!
