What we build / Suppliers, stock and purchasing

Suppliers, stock and purchasing

Who you buy from, on what terms, what's changed and what needs reordering.

What you lose without it

A supplier's price rise lands in an invoice and nobody notices for a quarter, so every quote since was under-priced. The best-selling line runs out on Thursday. Three accounts have early-payment discounts nobody claims.

What it holds

Suppliers with terms, contacts, account limits, discount terms and price-change history. Standing orders and their cycles. Reorder points on the lines that matter, with days of cover. Deliveries expected this week.

What it reads from

Supplier invoices as they are filed (the Inbox module or manual), the POS or inventory export for stock, and the price book so a rise flows into quoting.

What the morning check says about it

"Reece invoice shows copper up 6 percent on last order; price book not updated." "Two lines under reorder point; delivery from Bunnings Trade due Wednesday."

Where a spreadsheet stops being enough

Thousands of SKUs, multiple locations with transfers, or serialised stock. Then inventory belongs in the POS or an inventory system, and this module reads it.
