In this course, you'll build an **Uninvoiced Shipping Accruals Report** — a flow that matches uninvoiced shipments to a carrier rate card to estimate accrued shipping costs and export a journal entry file for ERP upload. Even if this doesn't resemble a process you manage day-to-day, it's a perfect example for learning the fundamentals.
