Position Summary

Our US-based client is hiring a Senior Staff Accountant to join the Accounting & Finance team in a permanent, full-time capacity. This is a hands-on, individual-contributor role, especially in the first four months: you will work directly in our billing and accounts receivable function, learning our systems and processes so you can independently cover our billing lead's full responsibilities while she is on maternity leave (expected November/December).Once she returns, your day-to-day will shift. Billing and accounts receivable will move to more of a supervisory role, and your time will be increasingly focused on accounts payable, expense management, general accounting, and direct support of our CFO — who remains very hands-on in the business today. We're looking for someone who is comfortable being deeply hands-on early on and is equally comfortable evolving into a broader, more oversight-oriented role as the team grows.

Key Responsibilities

First Four Months: Hands-On Billing & Accounts Receivable (Maternity Leave Coverage)

• Own the end-to-end invoicing cycle in Stripe, including subscription billing, manual/credit-card paying customers, and the monthly usage-based billing run (leveraging AI tools as part of that process)
• Serve as the primary point of contact for customer billing questions, including negotiating and tracking delayed payments
• Coordinate with our Professional Services Managers (PSMs/account managers) on account-level billing issues
• Work with the Professional Services team to know when billing should begin for new customers
• Manage cancellation and downgrade opportunities/deals in HubSpot
• Catch and correct invoicing errors — voiding and reissuing invoices, avoiding duplicates

 

Billing & Accounts Receivable (oversight)

• Review and validate billing/revenue activity for accuracy — a second set of eyes on invoicing to catch duplicates or errors before they compound
• Provide ongoing oversight and backup support for the billing process and accounts receivable
• Conduct a monthly review of customer usage against current pricing tiers to ensure accurate billing, and update subscription records when changes are needed
• Correspond directly with partners through our Billing email to address any inquiries and answer any direct customer needs 

• Classify and code company credit card transactions (most cards sync automatically to QuickBooks) to the correct vendor and GL account
• Manually enter transactions for the one card without a QuickBooks integration
• Reconcile all credit card accounts
• Organize a consistent, twice-weekly payment run to keep vendor and expense payments on schedule

• Monitor the company checking account daily
• Manage the Stripe → Synder → QuickBooks deposit workflow: bring in payment batches, clear them through the Synder clearing account, and confirm deposits hit the bank correctly
• Own the Synder integration as the go-to systems expert for that process
• Prepare monthly journal entries, including accruals (e.g., sales commission accruals)
• Manage the prepaid expense schedule — ensure accurate monthly amortization and maintain a calendar of upcoming large prepayments for cash planning
• Support the budgeting process — build and maintain budget-to-actual templates and prepare monthly budget-to-actual and fluctuation analysis
• Support ad hoc reporting and analysis for the CFO

• Background as a staff accountant, senior staff accountant, accounting manager, or billing manager
• Comfortable preparing journal entries, accruals, and reconciliations independently
• Experience with GAAP or IFRS; public accounting background is a strong plus
• Strong Excel or Google Sheets skills, including budget-to-actual and variance analysis
• Experience with QuickBooks Online required; familiarity with Stripe, Synder, or HubSpot a plus
• Comfortable using AI tools to support accounting workflows
• Detail-oriented with a review/audit mindset
• Excellent written English for direct customer communication
• Comfortable working as a hands-on individual contributor initially, with the flexibility to grow into a broader oversight role as the position evolves
