Sr. Accountant - Quickbooks Online /Multi-Entity

About the Opportunity

We are a growing, tight-knit professional services firm based in St. Louis that provides comprehensive outsourced accounting and financial operations support to a diverse portfolio of clients across industries including life sciences, SaaS, nonprofits, and more. Our team operates in an open, collaborative environment where personality is just as important as technical skill -- we work hard, invest in each other, and genuinely enjoy what we do. This is not a behind-the-scenes accounting role. You will be the point person for your clients, managing their day-to-day financial operations with an entrepreneurial mindset and a strong service orientation. If you thrive in a fast-moving, multi-client environment and want to own your work with minimal micromanagement, this is the role for you.

Day-to-Day Responsibilities

• Manage the full-cycle accounting operations for a portfolio of 5 to 7 clients across multiple industries, functioning as their primary accounting contact
• Own all aspects of month-end close including journal entries, accruals, prepaids, depreciation and amortization, and equity-related entries
• Prepare and review account reconciliations across bank accounts, credit cards, balance sheet, and P&L accounts
• Produce monthly financial packages including management reports, board decks, and investor updates
• Monitor cash flow and proactively advise clients on their financial position, including rolling forecasts and budget-versus-actual analysis
• Handle AP, AR, and payroll processing in coordination with client-preferred platforms
• Support clients with HR-adjacent functions including onboarding coordination, PTO tracking, and benefits-related fielding through payroll providers
• Assist clients with state business registration compliance and annual filing deadlines
• Build and maintain strong client relationships, serving as a trusted advisor across vendors, CPAs, and key stakeholders
• Collaborate with CPAs at year-end to deliver final financials, W-2s, 1099s, R&D tax credit support, and all necessary tax prep materials
• Participate in client board meetings and investor presentations when needed

Required Skills & Qualifications

• 5 to 10 years of professional accounting experience, with at least 2 years in a leadership or client-management capacity
• Proven ability to manage multiple client engagements simultaneously with strong attention to detail and time management
• Outstanding communication and interpersonal skills -- you must be comfortable running client meetings and engaging with executives, investors, and board members
• Strong proficiency in QuickBooks Online (QBO) -- this is a non-negotiable requirement
• Experience with AP and expense management platforms such as Ramp.com is a significant plus
• Familiarity with payroll software such as Gusto, JustWorks, Insperity, or similar platforms
• Proficiency in Excel and comfort learning new accounting and ERP tools quickly
• Familiarity with deferred revenue accounting, cash flow forecasting, and startup financial modeling is highly desirable
• Degree in Accounting, Finance, or a related field preferred
• CPA license is not required but any public accounting or multi-entity background is a plus

Why This Role Stands Out

• True autonomy -- once up to speed, you manage your clients like your own book of business with full ownership and minimal oversight
• Collaborative, energetic team culture -- this is not your typical accounting environment
• Exposure to diverse industries including life sciences, biotech, SaaS, and nonprofits
• Flexible hours with consistent schedule expectations -- no rigid 9-to-5 mandate
• Competitive compensation ($85K to $100K) plus medical, dental, vision, 401(k) with match, FSA, generous PTO, and life insurance
• Opportunity to grow with a firm that is actively expanding its client base
