Inventory tracks what you sell, what you have on hand, what you are buying, what actually arrived, and what inventory cost has been recognized. The area is split into Products, Suppliers, Purchase Orders, and Goods Receipts because ordering stock and receiving stock are separate events.

​
Products

Products carry identity, category, selling price, cost, stock behavior, images, and supplier relationships where configured. Stocked products participate in quantity movements and inventory valuation. Service or non-stock products can use different cost semantics because there is no physical inventory fulfillment to record. Start with Create a product and Stock levels and movements.

​
Suppliers

Supplier records store procurement identity and reusable defaults. Product-supplier relationships can hold vendor SKU, vendor price, currency, preferred status, and active state. A preferred supplier helps the business act quickly when a product reaches its reorder threshold.

​
Purchase Orders

A purchase order is the intent to buy. The builder supports supplier, PO number, order and expected dates, currency, exchange-rate context, terms, shipping and billing addresses, tax, freight, notes, and product lines with quantity and unit cost. Creating a PO does not increase stock. For a full walkthrough, see Create a purchase order.

​
Goods Receipts

A goods receipt records what physically arrived. It can separate accepted, damaged, and on-hold quantities and can represent partial delivery against a larger purchase order. Posting the receipt locks it for ordinary editing and applies the supported inventory consequences. If only part of the order arrived, the purchase order can remain partially received with the remaining quantity outstanding.

Receive a purchase order

Record a partial or full supplier delivery correctly.

Post a goods receipt

Understand the posting lock and stock consequences.

​
Stock movements and integrity

Current product stock should reconcile with the quantity movement ledger. Opening stock, receiving, fulfillment, and other supported movements should explain how the quantity changed. Do not fix an unexplained stock balance by editing the product number until you understand the source movement that is missing or wrong.

​
Replenishment and exceptions

Inventory automation can surface out-of-stock products, items below reorder level, overdue purchase orders, stalled partial orders, missing preferred suppliers, damaged deliveries, on-hold stock, and receipt posting issues. The Inventory overview also exposes attention metrics such as stock risk, incoming stock, overdue POs, outstanding PO value, active suppliers, and receipt posting review.

​
Inventory reporting

The active catalog includes Available Stock, Inventory Valuation Summary, Stock Movements, Reorder List, Goods in Transit, Slow Moving Stock, Open Purchase Orders, and Margin by Product. Open PO value uses the remaining quantity, not the original order total after partial receipt. Product margin for stocked items uses recognized fulfillment cost rather than assuming an invoice alone proves stock was delivered.

​
Permissions

Inventory access, product management, supplier actions, purchase orders, and goods receipts can be controlled separately. A finance user can have Inventory read access while operations users have broader procurement actions.

Next steps

Products

Create a product

Add a product to Inventory, choose the stock and cost information that matters, and understand how products connect to purchasing, invoicing, and reporting.

Understand stock levels and stock movements

Learn how Lynka reconciles current stock with movement history, opening quantity, goods receipts, fulfillment, and stock health reporting.

Reorder low stock and investigate slow-moving inventory

Use reorder levels, open replenishment, out-of-stock signals, slow-moving stock, and supplier relationships to decide what inventory needs action.

Understand product margin and recognized inventory cost

Learn how Lynka calculates product margin from invoiced sales and recognized fulfillment cost, including why stocked margin can be incomplete.

Suppliers

Create and manage a supplier

Add a supplier for purchasing, store procurement defaults, link products, and understand how supplier data is used by purchase orders.

Purchase orders

Create a purchase order

Create a supplier purchase order with line quantities, unit costs, currency, dates, tax, freight, payment terms, addresses, and FX context.

Purchase order statuses and outstanding quantity

Understand draft, open, partially received, received, closed, and cancelled purchasing states and how Lynka calculates what is still outstanding.

Receive a purchase order partially or in full

Record what actually arrived from a supplier, keep remaining quantities open, and understand how partial receiving affects stock and purchasing reports.

Goods receipts

Create a goods receipt

Record a supplier delivery with GRN number, dates, linked purchase order, accepted quantity, damaged quantity, and on-hold quantity.

Post a goods receipt

Understand what posting a goods receipt means, why posted receipts are locked, and how to handle posting review problems without rewriting history.

Record damaged and on-hold stock at receiving

Separate accepted, damaged, and on-hold quantities on a goods receipt so delivered stock is not all treated as clean available inventory.
