In this lesson, we'll walk you through recording Supplier Bills using the Simple Purchase Invoice stage in Cin7 Core. Building on your understanding of Order and Stock Receipt, you'll conclude the Purchase Order by syncing the Supplier Invoice, adding costs to products, and integrating with accounting platforms. Whether you prefer Receipt First or Invoice First, we'll explore both approaches and guide you through entering Invoice details, managing product lines, additional costs, and verifying totals. From authorizing the Invoice to handling Supplier Deposits and making payments, we'll cover each step thoroughly.
