• Complete draw checklists for monthly billing cycles for internal review.

• Coordinate with project managers and accounting staff to ensure all draw requirements are satisfied.

• Organize and upload all draw support documents to customer/GC portals once reviewed and approved.


Additional Expectations

• This role will temporarily operate out of our Maricopa office; we are expanding and will be opening a Phoenix office in 2026.

• Maintain highly organized digital folders and financial documentation.

• Communicate clearly with managers, office staff, and vendors.

• Meet internal deadlines for monthly billing, reconciliations, and month-end close cycles.
