About this role

ABOUT EVERTUNE AI

Evertune is building the first AI discovery platform for modern marketers. As large language models (LLMs) become the go-to source for recommendations – we help brands understand exactly what AI is saying about them, where they stand against competitors, and how to show up more often in AI-powered answers. Our platform turns black-box AI behavior into actionable insights, so marketing teams can make faster, smarter decisions that drive growth.

Founded by leaders who helped scale The Trade Desk into the world’s leading ad tech platform, we bring deep expertise in digital advertising, data, and high-growth environments. Now, we’re pioneering a new category at the intersection of AI, SEO, and brand strategy.

We raised a $15M Series A led by Felicis Ventures, with support from Eniac, NextView, Roger Ehrenberg, and leaders from OpenAI, Google, Meta, Uber, and more. This gives us the momentum to move faster and build the first enterprise-grade AI marketing suite.

Backed by top-tier VC investors and trusted by forward-thinking brands, we have the resources to scale – but what really defines us is our culture. We move fast, think boldly, and believe the best ideas win regardless of title. If you're excited about shaping the future of how brands grow in the age of AI, you’ll thrive here.

YOUR ROLE

We’re hiring a Billing Specialist to support our growing finance function and help keep Evertune’s billing and collections process running smoothly as we scale.

You’ll work directly under our Controller and own much of the day-to-day execution across invoicing, accounts receivable, and collections. Our billing process is complex and highly manual today, including usage-based billing inputs, customer-specific pricing rules, contract interpretation, invoice revisions, customer portal uploads, PO requirements, payment application management, and collections follow-up.

This is a hands-on role for someone who is highly detail-oriented, professional with clients, and comfortable operating in a fast-moving startup environment where the process is still being built. You should be energized by ambiguous work, able to follow through without a perfect playbook, and comfortable communicating directly with customers to resolve billing questions and payment delays.

You do not need experience with our exact finance stack, but you should be strong in spreadsheets, comfortable learning new tools, and meticulous when reading contracts and applying customer-specific billing terms. Experience with Stripe, QuickBooks, customer procurement portals, agency billing, usage-based billing, or collections is a plus.

This role requires being onsite in our NYC office in Flatiron Tuesday through Thursday. Candidates must currently be based in the New York City area.

YOUR TEAM

You’ll report to our Controller and work closely with the finance team as we build more structure around billing, AR, and collections.

You’ll also partner cross-functionally with Sales and Client Services on billing-related initiatives, including customer questions, invoice disputes, usage reconciliation, contract details, and collections escalation. Because this role will communicate directly with customers, we’re looking for someone who brings professionalism, patience, and a strong client-service mindset to every interaction.

- Upload invoices into customer portals and manage customer-specific submission requirements

- Track invoice status and ensure invoices are sent accurately and on time

- Own the end-to-end AR process once invoices are sent, including payment application, monitoring outstanding balances, and proactively following up on overdue accounts

- Pull weekly AR and collections reports for the Controller and maintain organized tracking of collections status, customer responses, and next steps

- Communicate directly with customers to resolve billing questions, invoice disputes, portal issues, and payment delays

- Partner with Sales and Client Services to escalate customer-specific billing escalations and flag where their involvement is needed to move collections forward

- Support the Controller on billing setup for new products, customers, or pricing structures as the business evolves

- Help identify recurring billing issues, manual bottlenecks, and opportunities to improve the process

- Support ad hoc finance and billing-related projects as needed in a scrappy startup environment

REQUIREMENTS

- Experience in billing, accounts receivable, collections, finance operations, accounting, client billing, or a related operational role

- Strong client-facing communication skills and a professional, patient, service-oriented approach

- Excellent attention to detail, especially when reading contracts, applying pricing rules, and reviewing invoices

- Comfortable with manual, repetitive, detail-heavy process work

- Strong follow-through and ability to proactively chase down payments, answers, and missing information

- Highly organized and able to track many invoices, customers, follow-ups, and edge cases at once

- Comfortable working in Google and Excel spreadsheets and manipulating billing or AR data

- Resourceful and able to operate without a perfect playbook, documented process, or step-by-step instructions

- Able to ask good questions when something is unclear, especially around contract terms or customer-specific billing requirements

- Comfortable working directly with cu
