About the role
We’re looking for a detail-oriented AP Specialist to manage the full-cycle accounts payable process for a busy commercial construction company. You’ll work closely with project managers, field staff, and the accounting manager to keep subcontractor, vendor, and supplier invoices posted accurately and timely and paid on time.

- Reconcile vendor statements; investigate and resolve discrepancies
- Support month-end close
- Maintain accurate vendor records and certificates of insurance in Sage 300
- Communicate directly with subcontractors and vendors to resolve billing issues
- Assist with annual 1099 preparation
- Support audits and provide documentation as requested by the Controller
Required qualifications
- 3+ years of accounts payable experience, with at least 2 years in commercial construction or a related trade industry
- Hands-on experience with Sage 300 Construction and Real Estate (Timberline) — AP module experience specifically
- Working knowledge of construction lien laws, conditional/unconditional lien waivers, and pay-when-paid provisions
- Hands-on experience with AIA payment applications (G702/G703) and subcontractor billing processes
- Hands-on experience with General and Administrative GL coding
- Strong attention to detail; able to catch coding errors before they hit the GL
- Comfortable working in a fast-paced environment with shifting priorities across multiple active projects
- Proficient in Microsoft Excel (pivot tables, VLOOKUP/XLOOKUP, basic reconciliation work)
Preferred qualifications
- Experience with certified payroll or prevailing wage projects
- Familiarity with One Drive or similar for referencing project data
- Associate degree in accounting (preferred)
What we expect
- Accurate work — we run on honest numbers
- Direct communication when something looks wrong, not silence
- Ownership of your queue; payment delays get caught and escalated before they become problems
