3. Itemized Receipts & Customer Financial Documentation

• Create detailed, itemized receipts for customers reflecting materials and services provided
• Ensure receipts align with contracts, change orders, and actual installed components
• Coordinate with sales, operations, and project management to validate accuracy
• Deliver clear and professional documentation to customers in a timely manner
• Maintain organized records of all customer-facing financial documents

4. Procurement, AP & QuickBooks Invoice Entry

• Enter vendor invoices into QuickBooks with high accuracy and proper coding
• Ensure all invoices are coded to the correct project, cost category, and account
• Match invoices to purchase orders and received materials (3-way matching where applicable)
• Review purchase orders for accuracy and completeness prior to invoice entry
• Ensure timely processing of invoices to maintain accurate financial reporting
• Track and resolve discrepancies between invoices, POs, and received inventory
• Maintain organized digital records of invoices and supporting documentation
• Collaborate with procurement to improve cost visibility, vendor accuracy, and pricing consistency
• Support month-end close by ensuring all invoices are entered and costs are captured in the correct period
• Procurement of all appropriate vendor documentation prior to payments and complete end of year tax filings

5. Systems & Process Improvement

• Maintain and improve inventory and project accounting systems (ERP, job costing tools, etc.)
• Identify inefficiencies in inventory tracking or cost capture and implement improvements
• Build reporting dashboards for inventory levels, usage trends, and project margins
• Support audits related to inventory and project financials

Qualifications

• Bachelor’s degree in Accounting, Finance, or related field
• 3+ years of hands-on accounts payable experience required (inventory or cost accounting experience is a plus)

Preferred Experience (Solar / Construction Industry)

• Experience in solar, construction, or trades-based environments
• Familiarity with solar components (modules, inverters, racking, batteries, BOS materials)
• Understanding of project lifecycle (sale → install → PTO → closeout)
• Experience working with field operations teams (installers, electricians, PMs)

Pay for this position is $28-$38 per hour, depending on experience. Overtime opportunities may be available depending on seasonality and business needs.
