Four traces, built one arrow at a time.
Trace one. Labour. A person records time. The cost is imported as an expenditure item. Priced using a rate schedule. Burdened. Accounted via a transaction account definition. Posted to the ledger. Six hops, each with its process named — because when it stops, you will need the name.
Trace two. An expense report or a supplier invoice, with the project and task coded on the transaction. Imported to costing. Accounted. Ledger.
Trace three. Billing and revenue. Costed expenditure items → contract bill plan → invoice generated → approved → transferred to Receivables. And separately — revenue recognized per the revenue plan → accounted → ledger.
COST AND REVENUE ARE TWO SEPARATE CHAINS THAT BOTH START AT THE EXPENDITURE ITEM. This is the insight to land. Learners consistently assume invoicing and revenue recognition are the same event. They are not. And the gap between them is unbilled and unearned — the two balances a project accountant lives with. If you remember one thing from this module, remember that those are two chains and not one.
Trace four. Capitalization. Costs collected on a capital project → asset assignment → placed in service → transferred to Assets → depreciation. Note the connection to the Financials course — that last hop is that course's territory.
That is the map. It terminates exactly where the Financials course begins.
