AP Specialist

Cornerstone Solutions Group is a Dade City, Florida-based portfolio company with operations spanning landscape and hardscape construction, commercial construction management, multi-location retail, fine furniture and interior design, and marketing services. Our accounting department operates as a shared services team supporting five entities with distinct business models. We are a growing team that values precision, process discipline, and ownership.

The Opportunity

We are looking for an Accounts Payable Specialist to join our shared services accounting team. In this role you will be the primary data entry owner for vendor invoices, credit card transactions, and vendor compliance documentation across our portfolio of companies. You will work closely with the accounting team and report to the Accounting Manager, supporting accurate and timely AP processing that keeps the department's close cycle on track. This is a detail-first, process-first role — the accuracy of what you enter determines the accuracy of every downstream financial report.

What You'll Do

• Enter vendor invoices for multiple entities in Sage Intacct with accurate GL coding, entity, department, and project dimension tagging.
• Perform 3-way PO match — purchase order, receiving document, and vendor invoice — before entering any bill
• Own the AP Aging review for multiple entities in Sage Intacct to ensure timely payment to vendors.
• Obtain and maintain W-9s and insurance certificates for new and existing vendors
• Assist with year-end 1099 preparation and vendor data accuracy throughout the year
• Route invoices through the approval workflow per entity-specific authorization requirements
• Support the accounting department with month-end close, AP aging review, and open item resolution
• Handle occasional in-office tasks such as incoming/outgoing mail.
• Assist with lien waiver process for subcontractor 

What We're Looking For

• 1+ years of accounts payable or accounting experience
• Demonstrated accuracy and attention to detail in high-volume data entry — errors in this role have downstream consequences

• Experience with Sage Intacct preferred; experience with another ERP (QuickBooks, NetSuite, Sage 300) considered. (We also use Sage Construction Management and BuildOps.)
• Familiarity with construction AP — subcontractor invoices, lien waivers, and PO matching — is a strong plus
• Intermediate Excel skills
• Organized and systematic — you will manage vendor files, compliance documents, and lien waiver logs across multiple entities
• Strong written communication skills for vendor correspondence
• Comfortable following established processes but able to identify when improvement is needed— consistent execution of AP workflows is a core expectation
• Must be able to work in our Dade City, FL office

We hire for culture as much as we hire for skill. Every member of our team is expected to:
