Inventory / Stock Control

Before you promise stock, know what is here and what is merely on the way.

Check on-hand quantity, reorder thresholds, incoming supply and movement history together, then use explicit controls for adjustments and negative stock.

Treat the current quantity as the result of movements, not a number to edit casually

Stocked products keep a current stock level that is changed through controlled stock movements. Receiving, customer fulfillment and manual adjustment leave different source evidence behind the quantity change.

That history is more useful than a balance that looks correct today but cannot explain how it got there.

Let the threshold ask a question, not place the order

Each stocked product can have a minimum-stock threshold. Reorder List identifies products at or below that level.

The list says 'review this item.' A buyer can still check incoming supply, recent demand, supplier price and lead time before deciding whether to replenish.

Keep open supplier quantity out of available stock

Goods in Transit shows outstanding quantities on open purchase orders, while available-stock reporting describes inventory that can actually be used under the report's reservation logic.

A PO expected next week should not become a promise to a customer today merely because the goods are on order.

Make every unusual quantity change leave a reason

Stock movements can retain product, quantity change, movement type, reference, source, reason and cost basis when available.

Manual stock adjustment has its own process and requires a reason, with a written explanation for applicable uncategorized adjustments. The balance changes without erasing why.

Low stock is not the only stock problem

Slow Moving Stock combines current inventory with sales activity to highlight products that are sitting without enough recent movement.

Sold quantity, sold value, last sale date, sell-through rate and days since last sale can provide a better reason not to reorder than the minimum threshold alone.

Decide explicitly whether the business can go below zero

Outbound posting can respect a workspace rule that controls whether inventory may become negative. When negative stock is disabled, a fulfillment shortage can stop posting instead of silently creating impossible stock.

A workspace can allow negative inventory deliberately when its operating model requires it. The important part is that the rule is a system choice, not a hope that everybody remembers.

That makes a customer promise, a purchase decision and a stock correction easier to explain because they are not all reading the same number as if it meant the same thing.

One stock number cannot answer every operational question. Lynka separates what is on hand, what is available, what is incoming and why the balance changed.

Questions about Stock Control

Can I set a minimum stock level?

Yes. Stocked products can have a minimum-stock threshold used by the Reorder List.
