Examples
Maple and labor sit on one job page
You run a custom millwork shop. On April 14 you start Job 184 for a clinic client, a reception desk; a hardwood supplier bills $1,860 of maple and shop labor that week is $940. You post both to Job 184 in the cost ledger (in QuickBooks Online, a Project stands in for that job page), and goods in process in the general ledger, the controlling account, rises $2,800. Open the cost ledger and you see maple and labor on Job 184; the general ledger only shows one WIP total. That subsidiary ledger of job cost accounts is the cost ledger, not a cost sheet (one product statement) and not the cost system (the whole method).
Vendor aging is not job cost
You run a commercial kitchen installer. In November you have three jobs in progress when a sheet-metal shop bills $4,200 of stainless and an electrician bills $1,150. You enter both bills in Xero to accounts payable and read the AP aging as if it told you job cost. That aging is the creditors ledger, a vendor subsidiary ledger, not a cost ledger; the customers ledger would only show who owes you after you invoice. Open a cost-ledger account (or a Xero project) for each job, post the stainless and electrical there, and keep the AP aging for who you owe; mix the three jobs on one Job Materials P&L line and you cannot summarize what each kitchen cost.
Why it matters
You need a cost ledger when you manufacture goods or produce services as jobs or processes, because the general ledger only holds a controlling account total for goods in process or job cost. The cost ledger is the subsidiary ledger of those job, process, and cost-pool accounts; you post to it whenever materials, labor, or overhead hit production, and you reconcile it to the controlling total at month-end. A reseller or a shop with no jobs almost never opens one. Treat it as the cost system (the whole method), a cost sheet (one product's statement), or the creditors ledger and customers ledger (vendor and customer books), and you will read AP aging or a single P&L materials line as if it told you job cost; in QuickBooks Online or Xero, Projects or a job-costing add-on is the usual stand-in for the paper book.
