Job costing & monthly close
Greywood CPA sets up and runs job cost accounting for contractors: cost codes, labor burden, equipment costs, change orders, retainage and a monthly close that ties every job back to the general ledger. Good job costing is what makes your WIP schedule, bids and surety statements reliable.
We work in the systems contractors already use, from QuickBooks to construction ERPs, and deliver a monthly package with job profitability, WIP and cash position. We are a licensed CPA firm working nationwide, at a fixed fee.

Job costs should be coded the same way you estimate, by phase and by type (labor, materials, subcontracts, equipment, other). That lets you compare actual to estimate line by line and catch overruns while there's still time to act.
Track pending, approved and rejected change orders separately so contract values in your WIP stay accurate. Retainage receivable and payable should be tracked by job, billed when due and collected before year-end where possible, since old retainage weakens your balance sheet in the surety's eyes.
