Purchasing

What this is

Purchasing is where goods come into the shop: what you order from a supplier, what arrives, what the supplier bills you, what you pay, and what you send back.

Everything hangs off one record, the purchase document. It carries the supplier, the warehouse the goods land in, the currency the price was agreed in, and the lines. Deliveries, invoices, payments and returns are all booked against it, so the document answers three questions at any time: what is still outstanding, what is still unbilled, and what is still unpaid.

What you use it for

  • Order goods and track what has not arrived yet.
  • Book a delivery — this is the moment stock and the purchase cost change.
  • Record the supplier's invoice and pay it, in full or in parts.
  • Let the system propose what to reorder, from consumption and stock cover.
  • Send goods back to the supplier and settle the amount.
