Cal Poly payroll and regional activity
University-related activity can involve construction, professional services and recurring operating work. A business supplying that work needs to distinguish each engagement and its billing terms. Separate reimbursable expenses from ordinary overhead, and reconcile customer receipts against invoices so a large institutional payer does not obscure overdue balances elsewhere.
- Cal Poly employs the full-time equivalent of 5,000 people with a total payroll of $403 million and an estimated $2.6 billion annual regional economic impact.

Modular housing and the Prado Road interchange
For modular construction, deposits, delivery milestones and installation labor may reach the books at different times. An interchange contract has its own scope and reporting instructions. Tidwell can help organize these records by project, with approved hours available for certified payroll and purchase commitments available for monthly cost review.

High school completion and campus improvements
A completed campus project can still leave a contractor with receivables, warranty-related expenses or supplier adjustments. Retain the campus and work-package reference during closeout. Reconcile those balances separately from new university housing work, even if the same accounting system handles both customers.
