Supply cycle

The module covers the whole inbound flow, from the order to stock entry, with a movement ledger (StockMovement) as the source of truth: current stock is never an estimate, it derives from the cumulative ledger.

Steps

1. Purchase orders (POs) — preparation, sending to the supplier, PDF export.
2. Receptions — goods entry; this is also when labels are printed.
3. Kits — grouping of products sold together.
4. Manufacturing — transformation / assembly of products.

Purchase orders

Why it matters

The purchase order (PO) is the document that formalizes your intent to buy from a supplier. Kept properly, it gives you:

• full traceability (who ordered what, when, at what price);
• a check on reception (compare received vs ordered, spot discrepancies);
• reliable supplier statistics (volumes, lead times, reliability);
• a clean base for accounting (purchases, supplier payables).

Procedure

1. Choose the supplier (it must already exist — see the supplier list in the Catalogue).
2. Generate the lines: add the products to order. Each line = one product, a quantity, a purchase price. You can rely on restock thresholds (min/max stock) to decide quantities.
3. Check the total, then save the purchase order (status draft).
4. Confirm / send the PO to the supplier (status sent) and export it to PDF if needed.

A good ordering procedure means: precise lines, an up-to-date purchase price, and a PO confirmed sent before delivery.

Receptions

On delivery, you record the reception: the quantities actually received enter stock (written to StockMovement), with lots and expiry dates captured for the relevant products.

Best practice

Always start from a purchase order: create the PO, confirm it sent, then receive each order from the purchase-order history — rather than receiving goods without a purchase order.

Receiving from the PO lets you:

• compare ordered vs received (quantities, prices) and trace discrepancies;
• keep the full supplier history;
• avoid "orphan" stock entries that can't be audited.

A reception without a PO remains possible (fallback), but should stay the exception.

Labels

Labels (EAN-13 / Code128 barcodes) are usually printed at reception, from the supplied A4 sheet templates.

Formats

Several sheet formats are available. In practice, the best formats — a good readability / density / cost trade-off — are the 40-label and 65-label per A4 sheet layouts. Prefer these for your day-to-day printing; reserve very large formats for special cases (aisles, gondolas).

Labeling well at reception guarantees a reliable scan at checkout and a faster inventory.
