Westates Mechanical is seeking a Full-Charge Bookkeeper to serve as the financial and administrative backbone of the business. This is a highly trusted, hands‑on role responsible for owning the full accounting cycle, supporting construction-specific billing and compliance, and gradually assuming full payroll ownership.

This role is ideal for someone who thrives in a small, focused construction office, takes ownership with limited oversight, and confidently manages complex, detail-heavy accounting processes while partnering closely with ownership, project managers, and external advisors.

• Own the full accounting cycle, including general ledger maintenance, journal entries, accruals, reconciliations, and month‑end close
• Prepare and maintain monthly cash flow projections, AR projections, and financial tracking schedules
• Record and reconcile bank accounts, credit cards, and balance sheet accounts
• Prepare recurring and adjusting journal entries, including WIP, prepaid expenses, lease amortization, and P&L adjustments
• Support quarterly and annual accounting requirements, including preparation of required filings (e.g., 1099s, gross receipts reporting, property tax filings, and other regulatory documentation)
• Ensure books are accurate, compliant, and audit‑ready, escalating complex accounting questions to leadership or external advisors when required.

• Work closely with remote AP/AR support to ensure vendor invoices, credit cards, and payments are accurately recorded, coded, and allocated to the correct jobs and accounts
• Review and reconcile vendor statements, AP aging, and payment activity
• Prepare and process vendor payments as needed and provide coverage when required
• Oversee and manage conditional and unconditional vendor lien waivers, ensuring compliance with project and contract requirements
• Ensure AP activity is properly reflected in accruals, reconciliations, and month‑end close

• Partner with remote AP/AR support to ensure customer invoices, pay applications, and deposits are accurate, timely, and correctly recorded
• Own the reconciliation of AR activity across accounting systems, projection logs, and customer‑required billing platforms, ensuring billing activity is accurately reflected in the accounting system
• Review job cost reports, WIP, SOVs, and AR projections for accuracy and completeness
• Maintain oversight of invoice logs, collections tracking, and billing schedules
• Ensure conditional and unconditional customer lien waivers are prepared, submitted, and filed in accordance with contract requirements

• Initially support weekly payroll processing, including timecard entry, payroll reconciliation, and coordination with payroll systems, with hands‑on training and knowledge transfer
• Maintain payroll records and support payroll‑related audits (e.g., workers’ compensation, union, or insurance audits)
• Prepare and submit certified payroll reports and union fringe benefit transmittals, with oversight and guidance as needed
• Maintain employee payroll classifications, union rates, and deductions in payroll systems
• Over time, transition into full ownership of payroll processing, reporting, and reconciliation as the role ramps…
