  • Identify discrepancies and coordinate with vendors and internal teams to resolve issues before processing
  • Support execution of recurring check runs and scheduled payments
  • Maintain and organize vendor files, records, and supporting AP documentation
  • Support new vendor setup by collecting and maintaining accurate vendor information
  • Assist with responding to vendor inquiries related to invoice status and payments
  • Assist with reconciliation activities, including vendor statements and credit card transactions
  • Assist the AP team with month-end close activities, including organizing and reconciling documentation
  • Track invoice approvals and follow up internally to help prevent payment delays
  • Support additional administrative and accounting-related tasks as needed

 

Must have's:

  • Understanding of A/P processes, including invoice review and basic payment workflows
  • Strong attention to detail with the ability to identify discrepancies in invoices and documentation
  • Comfort working with Microsoft Excel
  • Ability to manage multiple tasks in a structured, detail-oriented environment
  • Strong communication skills for working with vendors and internal teams
  • Reliable, organized, and able to follow through on assigned tasks independently

 

Nice to Have Qualifications:

  • Previous experience with A/P, invoice processing, or bookkeeping
  • Exposure to vendor payments, check runs, or reconciliation processes
  • Experience working in accounting software or ERP systems
  • Experience supporting vendor setup or maintaining vendor records
  • Prior experience in construction, landscaping, or subcontractor-driven environments

 

Compensation and Perks:

  • Competitive hourly compensation based on experience
  • Flexible part-time schedule
  • Opportunity to gain hands-on accounting experience with a stable, established company.
  • Potential for short- and long-term growth and expanded responsibilities over time
  • Collaborative and supportive team environment
  • Company culture includes team events, holiday celebrations, and office-wide engagement activities
