About the role

The Sales Operations Analyst owns the post-sale financial engine: everything that happens after a deal closes. Your mission is simple to state and hard to do well: make sure every dollar of usage is billed cleanly and collected on time, and make it effortless for our customers' procurement and finance teams to pay us. You will be the operational counterpart to customer procurement, the owner of invoicing accuracy, and the person who keeps our revenue data trustworthy.

This is a high-ownership role with real room to grow. You will build processes where little exists today, and the systems you create will scale with the company.

What you'll do

• Own billing operations and data across all systems. You are the owner of billing operations end to end, and of the accuracy and integrity of billing data everywhere it lives: HubSpot, Chargebee, spreadsheets, and any downstream financial system. One trusted picture, maintained by you.
• Own invoicing. Create and issue accurate invoices, ensuring usage-based charges are captured correctly against each customer's entitlements, and that every invoice is delivered on the agreed date.
• Manage customer procurement and vendor portals. Be the point of contact for customer procurement and accounts-payable teams. Understand and align with each customer's purchasing process, and maintain and manage the vendor portals (e.g. Ariba, Coupa, and customer-specific systems) that each customer requires: vendor onboarding forms, POs, tax and compliance documents, and payment terms.
• Partner across the business. Work closely with Sales and Customer Operations so that deals flow cleanly from close to provisioning to billing, with no gaps between teams.
• Drive quote-to-cash. Shepherd each closed deal from order through invoice to collection, keeping the process fast, accurate, and clean.
• Run AR and collections. Monitor aging, follow up on overdue invoices, resolve disputes, and flag at-risk balances early.
• Keep the data honest. Reconcile CRM, billing, and accounting systems so the company operates from one trusted post-sale picture, and fix leaks and mismatches at the source.
• Improve the machine. Find the manual, error-prone, and leaky steps in quote-to-cash and systematically remove them.

Tools you'll work with

Day to day you'll work primarily in Excel / Google Sheets, HubSpot, and Chargebee (for billing operations, reconciliation, CRM data, and reporting), and in QuickBooks as needed for accounting and finance. Strong spreadsheet skills and comfort moving data cleanly between systems are essential.

How success is measured: KPIs

The metrics you'll own and report on:

• On-time invoice delivery: every invoice delivered on the contract start date or a date mutually agreed with the customer.
• Quote accuracy: 100%; every quote validated and correctly reflected in billing with no discrepancies.
• Invoice accuracy: invoices issued with no disputes or adjustments.
• AR overdue: past-due balances kept below 10% of total accounts receivable.
• Days sales outstanding (DSO): how quickly invoices convert to cash.
• Billing leakage: usage under-billed or missed; the goal is zero.
• Collections effectiveness: share of billed revenue collected within terms.
• Procurement & vendor-portal turnaround: vendor onboarding, POs, and portal submissions completed within each customer's required window.
• Dispute resolution time: how quickly invoice disputes are investigated and closed.
• Data integrity & reconciliation: billing data matched and consistent across HubSpot, Chargebee, QuickBooks, and spreadsheets.

Requirements

• 1 to 3 years in a billing, finance, revenue, sales operations, or accounts-receivable role.
• Strong spreadsheet skills (Excel or Google Sheets) and comfort moving data cleanly between systems.
• High accuracy and attention to detail with numbers and data; a low tolerance for errors.
• Clear, professional written communication, especially for customer-facing billing and collections.
• A self-starter who owns a process end to end and follows through.
• Comfortable working across Sales, Finance, and customers to get things done.

Nice to haves

• Experience with a billing system such as Chargebee or Stripe Billing, and/or QuickBooks.
• Experience with HubSpot or another CRM.
• Exposure to usage-based or SaaS billing and quote-to-cash.
• Familiarity with customer procurement portals (Ariba, Coupa) and PO-based invoicing.
• Familiarity with AI tools for automating repetitive finance and operations work.
• Interest in, or exposure to, technical, engineering, or scientific products.

Benefits

• Competitive compensation with equity of a fast-growing startup.
• Medical, dental, and vision health insurance.
