1. How Timesheet Costs Post to a Job
When a timesheet is approved, it creates Job Journal Lines (Type = Resource).
Posting these lines creates:
Job Ledger Entries → records usage for the job.
G/L Entries → cost posts based on Direct Unit Cost from the Resource Card.
The G/L accounts used come from:
General Posting Setup (via Resource Posting Group on the Resource Card).
There’s no separate “WIP account” here — the actual cost hits the Job Cost Applied accounts.
2. Why You See WIP Only for Materials
WIP in Business Central is controlled by:
Jobs Setup → WIP Method (Cost Value, Sales Value, % Complete, etc.)
Job Posting Group → defines WIP accounts for Cost and Sales.
Many default WIP methods only track Item costs (materials) unless the Job Posting Group is set up to also include Resource costs.
If your posting group for resources points to expense accounts (not WIP accounts), the cost will go straight to P&L instead of WIP.
3. How to Include Labor (Timesheets) in WIP
Check Jobs → Job Posting Groups → ensure Resource costs map to a WIP Cost Account (not just an expense account).
Run Process → Calculate WIP after posting timesheets.
Post the WIP to G/L so the labor costs move into WIP.
