About Alpine Tree Service

Alpine Tree Service is a growing, family-owned tree care company serving Northern New Jersey. We are a fast-paced, operationally driven business focused on delivering a high-quality customer experience, staying organized, and scaling the company the right way.

We are looking for a part-time bookkeeper who is experienced, detail-oriented, reliable, and comfortable working in a small business environment where accuracy, follow-through, and communication matter.

This is not a passive data-entry role. We need someone who can keep the books clean, stay on top of invoicing and receivables, help us understand where the money is going, and support better financial decision-making through timely, accurate reporting.

Role Overview

The Part-Time Bookkeeper will be responsible for day-to-day bookkeeping functions for Alpine Tree Service, as well as basic bookkeeping support for two related rental properties. This person will manage transaction entry, account reconciliation, invoicing, accounts receivable follow-up, accounts payable tracking, and monthly financial reporting support.

The ideal candidate has strong bookkeeping experience, understands small business accounting, is comfortable asking questions when something does not look right, and can make friendly but firm collection calls when invoices become past due.

• Escalate collection concerns when needed.
• Help improve the companys process for reducing overdue balances.
• Provide regular updates on outstanding receivables.

Accounts Payable & Expense Tracking

• Track vendor bills, recurring charges, subscriptions, and operating expenses.
• Help ensure bills are entered, categorized, and paid appropriately.
• Flag questionable, duplicate, incorrect, or unnecessary charges.
• Support expense organization so leadership can clearly understand spending.

Monthly Close & Reporting Support

• Assist with monthly close procedures.
• Prepare basic monthly financial reports for leadership review.
• Help ensure financial information is complete, accurate, and available on time.
• Provide summaries of key bookkeeping items, open issues, and follow-up needs.
• Support budgeting, cash flow visibility, and financial organization as needed.

Rental Property Bookkeeping

• Track income and expenses for two rental properties.
• Assist with clean monthly reporting for each property.
• Keep property-related transactions organized and properly categorized.
• Coordinate with ownership on missing information, reimbursements, or unusual expenses.

Qualifications

• Prior bookkeeping experience required, preferably in a small business environment.
• Experience with QuickBooks or similar accounting software strongly preferred.
• Strong understanding of basic bookkeeping, account reconciliation, invoicing, AR/AP, and monthly reporting.
• Comfortable making professional collection calls in a friendly but direct manner.
• Strong attention to detail and accuracy.
• Able to work independently and follow through without constant supervision.
• Comfortable identifying problems and bringing them forward with suggested solutions.
• Organized, deadline-driven, and consistent.
• Experience with service businesses, construction, trades, landscaping, tree care, or property management is a plus.
