Glossary

Key terms used throughout StackKnack documentation.

A

Authentication

StackKnack uses a token-based system that connects to third-party platforms via OAuth. Each integration requires a one-time authorization flow.

B

Bidirectional sync

Inventory data flows in both directions between StackKnack and a connected platform. When a sale happens on Shopify, StackKnack updates. When inventory is adjusted in StackKnack, Shopify updates.

C

Channel

A sales channel is any platform where you list items for sale. Examples include Shopify, StockX, eBay, and in-store POS. StackKnack treats each as a separate channel.

Committed inventory

Items that are reserved or sold on one channel but not yet fulfilled. Committed inventory is subtracted from available inventory on other channels to prevent oversells.

Consignment

A selling arrangement where a consignor provides items to a store, and the store sells them on the consignor's behalf. The store takes a commission and pays the consignor after the sale.

Consignor

The person or business that provides items to a consignment store. StackKnack tracks items by consignor and calculates payouts.

D

Dead stock

Items that have been listed for sale but have not sold within a configurable time window. StackKnack flags dead stock so operators can take action such as repricing or delisting.

I

Inventory reconciliation

The process of comparing expected inventory counts with actual counts. StackKnack performs continuous reconciliation across all connected channels.

M

Margin

The difference between the selling price and all associated costs, including purchase price, platform fees, and shipping. StackKnack calculates margins per item and per channel.

Multi-location

Operating from more than one physical location. StackKnack supports multi-location inventory tracking with separate counts per location.

O

Oversell

Selling an item that is no longer available. This happens when the same item is listed on multiple platforms and sells on two of them simultaneously. StackKnack prevents oversells through real-time committed inventory tracking.

P

POS (Point of Sale)

The system used for in-store transactions. StackKnack integrates with Clover POS to sync in-store sales with online inventory.

S

SKU (Stock Keeping Unit)

A unique identifier for each product variant. StackKnack uses SKUs to match items across different sales channels.

Settlement report

A report generated for consignment payouts. It lists all items sold for a consignor during a period, the sale prices, commissions taken, and the net amount owed.

Sync

The process of keeping inventory data consistent across all connected platforms. StackKnack performs real-time sync when sales, returns, or inventory adjustments occur.

V

Variant

A specific version of a product defined by attributes like size, color, or condition. A Nike Air Jordan 1 in size 10, new condition is one variant. The same shoe in size 11 is a different variant.
