Job Specifications

Title: Sage Implementation Manager

Type: Contract Only -1099

Location: Reston VA—Remote Flexibility

Reports To: CFO

Muller is looking for a hands-on Sage Implementation Manager to lead the full lifecycle of our Sage implementation — from assessment and design through data migration, testing, and training. This is a 1099 contractor role offering 100% remote work, ideal for a results-driven professional who thrives in fast-paced environments and knows how to turn complex accounting systems into efficient, integrated solutions.

Disclaimer: The following description has been designed to indicate the general nature and essential responsibilities of work performed by employees within this classification. It is not a comprehensive inventory of all duties, responsibilities, and qualifications required.

Responsibilities:

Needs Assessment:

Evaluate the Chart of Accounts, general ledger structure, job costing, project billing and profitability, retainage and WIP tracking, purchase orders, vendor and subcontractor billing and payment process tracking, AP approval workflow, PO processing workflow, and custom reporting needs. Review multi-entity reporting requirements, consolidations, and reconciliations. Document core workflows and develop a comprehensive project plan with integrations for additional applications, including milestones and a timeline.

Design and Configuration:

Assist with module identification and configuration based on assessed needs. Explore and define requirements for system integrations with Salesforce, InEight, and payroll.

Data Migration:

Oversee the migration of historical financial data, vendor and client records, and job records. Conduct data validation and assist with setting up additional entities, replicating processes for smaller (non-DFM) companies.

Testing:

Test job setup and billing, AP approval workflows, subcontractor payment tracking, and PO workflows. Validate system integrations with InEight, Salesforce, and payroll. Test banking and credit card live feeds and explore options for an AR payment portal. Review reporting functionality and develop custom reports to replace spreadsheets (e.g., contract matrix, WIP report, joint project tracking, and subcontractor payment tracking from invoice receipt to client payment). Identify and resolve technical issues in the test environment.

Training and Documentation:

Support user training for accounting staff and project managers. Document all core workflows and customizations.

Requirements:

5+ years of Sage Intacct implementation experience (Construction focus strongly preferred)
Strong knowledge of construction accounting, WIP, retainage, and AIA billing
Project management experience; ability to drive deadlines and clearly communicate with accounting and project management personnel
