Job Summary

The Full-Service Bookkeeper is responsible for maintaining accurate and complete financial records across one or more entities within the Mainspring corporate structure. This role owns the day-to-day bookkeeping cycle — accounts payable, accounts receivable, bank and credit card reconciliations, payroll journal entry support, and general ledger maintenance — and works closely with the Senior Finance Executive and Controller to support month-end close, budget-to-actual reporting, and audit readiness. This is a hands-on role suited to someone who is detail-oriented, comfortable working across multiple entities and cost centers, and experienced with QuickBooks Online in a multi-site or healthcare environment.

Key Responsibilities

• Maintain accurate, up-to-date books in QuickBooks Online for one or more Mainspring entities, including timely coding and posting of transactions to the correct entity, class, and location.
• Process accounts payable end-to-end: enter and code vendor bills, verify approvals, schedule/process payments, and maintain organized vendor and W-9 files.
• Manage accounts receivable, including invoicing, cash application, and follow-up on outstanding balances as applicable.
• Perform monthly bank, credit card, and balance sheet account reconciliations, researching and resolving discrepancies promptly.
• Record payroll journal entries and support reconciliation of payroll register data (Rippling/Paycom) to the general ledger, including accruals across pay periods.
• Distinguish and properly allocate corporate/shared costs versus true facility-level vendor spend across entities (e.g., legal, consulting, insurance, and other shared expenses).
• Support month-end and year-end close processes, including journal entries, account analysis, and preparation of supporting schedules.
• Assist with budget-to-actual reporting by compiling and organizing monthly data from facility-level workbooks.
• Maintain organized, audit-ready documentation and support responses to auditor and lender inquiries as needed.
• Track and reconcile intercompany transactions and management fee allocations across related entities.
• Identify and escalate discrepancies, unusual variances, or process gaps to the Senior Finance Executive or Controller.
• Assist with ad hoc financial reporting, vendor setup, and special projects as assigned.

• Three to six years of progressive accounting experience, preferably in healthcare multi‑entity environments, or private equity‑backed companies. 

Knowledge / Skills

• 3+ years of full-cycle bookkeeping or staff accounting experience, ideally in a multi-entity, multi-location, or healthcare/behavioral health environment.
• Strong working knowledge of QuickBooks Online required; QuickBooks Desktop experience a plus.

• Familiarity with AI (Claude) a plus
• Experience with payroll/HRIS platforms such as Rippling or Paycom, or willingness to learn, preferred.
• Understanding of GAAP-basis bookkeeping fundamentals and month-end close procedures.
• Excellent attention to detail and organizational skills; comfortable managing recurring deadlines across multiple entities simultaneously.
• Strong written and verbal communication skills, with the ability to work directly with facility staff, vendors, and finance leadership.
• Discretion in handling confidential financial and patient-adjacent business information, consistent with healthcare industry standards.

Preferred (Not Required)

• Experience in behavioral health, substance use disorder treatment, or another regulated healthcare setting.
• Exposure to multi-state payroll tax considerations.
• Familiarity with intercompany accounting and management fee/allocation structures.

Working Conditions
