Examples
Sheet goods tagged the day they arrive
You run a closet shop, and on September 12 a sheet-goods supplier invoices $1,240 of maple plywood for a hallway install. You enter the bill that day to job materials and tag it to that hallway project (a Project in QuickBooks Online, or a tracking category in Xero). Shop hours for that week go on the same job. That is direct costing: you assign each direct cost as it is incurred, not later from a pile of untagged bills. Open the job and you should see plywood and labor before you invoice.
A close with no jobs on the P&L
You run a window-tint shop. Through June you code every film-supplier bill and installer paycheck to Materials and Wages with no customer job. At the June 30 close the P&L shows $3,420 of film and $5,100 of wages, but the dealership lot and the three downtown storefronts look the same. That is period expense with no assignment, not direct costing. Recoding from memory after close is a cleanup; pick the job when you enter the next bill so each install shows its own cost as you incur it.
Why it matters
Direct costing is the method of tagging vendor bills and labor to the product or job they belong to as you incur them. You will do this on most purchase and payroll days if you track job or product cost; a shop that only reads a period P&L almost never does. A direct cost is one of those lines; direct costing is the process of assigning them as they happen, not a single expense account. Leave every bill in period expense with no job and you cannot see which work made money; wait until month-end to guess the split and the assignment is already late.
