Sage 100 Contractor Bookkeeper (Construction Accounting)

You know construction accounting. You know Sage 100 Contractor. And you take pride in getting it right.

At Syscon, we help construction companies stay accurate, organized, and in control of their financials. This role is focused on supporting a portfolio of clients through outsourced bookkeeping, payroll, and day-to-day accounting support within Sage 100 Contractor.

This is a hands-on role for someone who takes ownership of their work, manages multiple priorities, and follows through without needing constant direction.

This is a senior-level, client-facing accounting role requiring deep Sage 100 Contractor expertise.

This role is designed for someone who wants to build long-term stability in a hands-on, client-facing accounting position.
