About The Role

We are looking for a highly driven AR / Project Billing Specialist to own and execute our billing and collections processes for enterprise customers. This role will partner closely with the Revenue Accounting Manager and play a critical role in ensuring timely, accurate billing and accelerating cash collections.

This is a hands-on, execution-focused role — ideal for someone who thrives in the details, is persistent in following up with customers, and knows how to navigate complex enterprise procurement and payment environments (e.g., Coupa, Ariba, customer portals).

You will be instrumental in helping us reduce DSO, shorten time-to-bill, and drive toward a 5-business-day billing and AR close.

 

What You’ll Do

• Own end-to-end project-based billing, including invoice preparation, validation against contracts/SOWs, and timely delivery to customers.
• Navigate and manage customer procurement and payment portals (e.g., Coupa, Ariba, and similar systems) to ensure invoices are submitted correctly and without delay.
• Proactively drive collections efforts — follow up consistently with enterprise customers via email, portals, and calls to resolve outstanding invoices.
• Partner with Sales, Delivery, and Accounting to resolve billing discrepancies, disputes, and contract-related issues quickly.
• Monitor AR aging and take action to reduce DSO and improve cash collections performance.
• Ensure all billing aligns with contract terms, milestones, and project deliverables.
• Support a fast and efficient month-end close, helping achieve a 5-business-day billing/AR close timeline.
• Maintain accurate and up-to-date records in QuickBooks Online (QBO) and other billing systems.
• Reconcile billed revenue to underlying project data and ensure proper association of costs and revenue where applicable.
• Identify and implement process improvements to streamline billing, invoicing, and collections workflows.
• Assist in maintaining documentation and audit support related to billing and AR processes.
• Communicate clearly with internal and external stakeholders to ensure smooth billing and payment cycles.

 

Required Qualifications

• 3+ years of experience in accounts receivable, billing, or project-based invoicing roles
• Strong experience with project-based / milestone / services billing
• Proven track record of managing enterprise collections and reducing DSO
• Hands-on experience with customer payment and procurement portals (e.g., Coupa, Ariba, or similar)
• Experience working in QuickBooks Online (QBO) or similar accounting systems
• High attention to detail and ability to manage multiple invoices, accounts, and follow-ups simultaneously
• Strong organizational and follow-through skills — you don’t let things slip
• Comfortable working cross-functionally to resolve billing and payment issues quickly
• Ability to operate in a fast-paced, evolving startup environment
