We're looking for a high agency person with a strong understanding of and an interest in startups, who enjoys bringing order to messy books and thrives working across several new clients at once.

• Assess each client's current accounting systems, chart of accounts, tech stack, and historical books to identify cleanup needs, gaps, and risks.
• Set up new clients in Topo's systems and tools, including chart of accounts design or restructuring, bank and credit card feeds, and integrations with payroll, billing, and expense platforms.
• Perform historical cleanup, including account reconciliations, catch-up bookkeeping, reclassifications, and adjusting entries, so balances are accurate and supportable.
• Run the client's first month-end closes with Topo, establishing close checklists, reconciliation schedules, and reporting packages, and support initial budget and cash flow setup where in scope.
• Document and implement accounting processes and workflows (e.g., AP, AR, payroll, revenue, and expense management), recommending improvements where needed.
• Coordinate with  tax advisors, and prior accountants to obtain records and resolve open items, ensuring timely and accurate completion of deliverables.
• Support and guide Topo team members assisting on onboarding engagements.
• Research technical accounting questions that arise during cleanup and setup, and provide guidance internally and to clients.
• Prepare complete handoff documentation and support a smooth transition to the ongoing Topo accounting team.

What You'll Need:

• You're organized and demonstrate a high attention to detail and accuracy.
• You're a self-starter who can put ideas into action.
• You love working with numbers and helping people.
• You enjoy diagnosing and cleaning up messy books, and you take pride in leaving things better than you found them.
• You're comfortable working directly with clients, asking good questions, and setting clear expectations during a period of change.
• You can manage several onboarding engagements at different stages, keep each on track against tight timelines, and write clear documentation others can pick up and run with.
• You have the ability to quickly shift from high-level strategic thinking to tactical execution.
• 4+ years in public accounting, corporate accounting or finance, or similar experience, including month-end close, reconciliations, and cleanup or catch-up accounting.
• Excellent quantitative skills with strong experience in spreadsheet software and familiarity with Quickbooks; experience implementing or migrating accounting systems and integrated tools is a plus.
