Retail operations glossary
From WMS to FEFO, from e-Invoice to omnichannel: the terms of retail operations. We explain each concept in plain language and by what it is actually for.
Warehouse operations terms
Concepts that define stock movement within the warehouse, from receiving to shipping, the picking flow and traceability.
WMS Warehouse Management System
A warehouse management system is software that digitally manages receiving, putaway, picking, packing and shipping. It knows in real time where and how much stock is at location level and guides warehouse staff step by step. Today's WMS work together with handheld terminals, barcodes and robots (AMR/AGV).
In HaROS WMS: Warehouse workflows are set up to work together with robots. Explore →
FEFO First Expired, First Out
A stock rotation rule that ensures the product nearest to its expiry date ships first. It is used to reduce waste and destruction in categories where expiry date is critical, such as food, cosmetics, pharmaceuticals and cold chain. The system automatically determines which lot is picked first.
In HaROS WMS: FEFO and FIFO rules are applied automatically during picking. Explore →
FIFO First In, First Out
A rotation method in which the stock that entered the warehouse first leaves first. It limits product aging and shelf-life loss; it is the standard approach for products that are not date-sensitive but carry an obsolescence risk. WMS sets picking priority by the lot/batch entry date.
In HaROS WMS: Rotation rules are applied automatically at lot level. Explore →
Slotting
Planning the shelf and zone locations of products in the warehouse so as to maximize picking efficiency. Fast-moving products are placed near the picking path and heavy products in ergonomic positions. A good placement plan noticeably shortens walking distance and picking time.
In HaROS WMS: It suggests the best shelf location based on product movements. Explore →
ABC Analysis
Dividing products into classes A (most critical), B (medium) and C (low) by their contribution to revenue or turnover rate. High-value A products get more frequent counting, better locations and higher safety stock. It is the basic method of prioritization in stock management.
In HaROS WMS: ABC classes determine counting frequency and shelf placement. Explore →
Wave Picking
Picking orders in groups (waves) rather than one by one. Orders passing through the same zone or going to the same carrier are planned together; this reduces movement in the warehouse and synchronizes picking with shipping times. It noticeably increases efficiency in busy e-commerce operations.
In HaROS WMS: You set wave and batch picking strategies according to your own rules. Explore →
Hero Picking Best-seller route
A method in which best-selling SKUs are picked in bulk along a single route. An operator takes the same SKU belonging to dozens of orders onto the cart in one go and verifies it with a single barcode scan. Walking and scanning repetition drop, and picking gets faster.
In HaROS WMS: The same SKU from 50 orders goes onto the cart with a single barcode; Comnous AI plans the routes. Explore →
Handheld / RF Terminal
A handheld radio-frequency (RF) terminal device through which warehouse staff receive tasks by scanning barcodes. It verifies receiving, putaway and picking steps in real time and warns instantly on a wrong product or location. It noticeably reduces the error rate compared with paper lists.
In HaROS WMS: Handheld terminal and barcode flows come as standard. Explore →
AMR / AGV
An AMR (Autonomous Mobile Robot) is an autonomous robot that senses its environment with sensors and freely determines its route; an AGV (Automated Guided Vehicle) is a guided carrier that follows a fixed line or markers. Both automate bringing goods to the operator and transport tasks in the warehouse.
In HaROS WMS: Robot tasks are tied to warehouse workflows. Explore →
Cycle Count
Instead of closing the whole warehouse and counting at once, small sections of stock are counted continuously at regular intervals. Stock accuracy is kept high without stopping operations; deviations are caught early. A products are usually counted more often by ABC class.
In HaROS WMS: You plan counting tasks and monitor deviations. Explore →
Replenishment
Refilling stock in picking locations from the reserve storage area in time. The aim is to prevent the shelf from emptying during picking and keep the flow uninterrupted. The system automatically triggers the replenishment task for locations that fall to the minimum threshold.
In HaROS: Replenishment tasks are generated automatically by threshold rules — Explore →
Cross-dock
Transferring incoming goods directly to outgoing shipments without shelving them in the warehouse. It lowers storage cost and handling time; it is used for fast-moving or pre-allocated products. Goods from the supplier flow almost without stopping from receiving to the exit dock.
In HaROS WMS: You define the cross-dock flow at receiving. Explore →
Lot Traceability
Keeping on record, from start to finish, which production batch (lot/batch) a product came from. It is critical for expiry tracking, product recall and regulatory compliance. When a batch turns out to be problematic, all stock and shipments belonging to that lot can be traced instantly.
In HaROS: Lot/serial tracking is built in from receiving to shipping — Explore →
Order management terms
Concepts that define where, how and from which stock a multi-channel order is fulfilled.
OMS Order Management System
An order management system is the layer that collects and manages all orders from store, website, marketplace and B2B channels in a single pool. It decides from which stock and which point each order is fulfilled and tracks its status end to end. It is the center of omnichannel retail.
In HaROS OMS: Orders from all channels are collected in a single pool. Explore →
Omnichannel
A retail model in which store, online and marketplace channels are managed not separately but with a single stock and single order pool. The customer moves seamlessly between channels; an online order can be fulfilled from a store, a store request from the warehouse. Stock appearing consistent in every channel is the basic condition.
In HaROS OMS: Stock is visible from the same data in all channels. Explore →
Split Shipment
Sending the products of a single order from different points (e.g. some from the warehouse, some from a store) as separate shipments. If the products are not at a single location, it gets the order to the customer as fast as possible instead of cancelling it. It balances shipping cost and delivery speed.
In HaROS OMS: Sourcing rules decide whether an order is split. Explore →
Click & Collect
The model in which the customer buys online and collects the product from a store. It lowers shipping cost, drives traffic to the store and speeds up delivery. For it to work well, store stock must appear in real time and accurately in the online channel.
In HaROS OMS: Store stock is visible instantly in the online channel. Explore →
Ship-from-store
Picking and shipping online orders from store stock instead of the central warehouse. The store turns into a mini fulfillment center; stock close to the customer speeds up delivery and spreads the warehouse load. Store stock accuracy and picking discipline are critical for success.
In HaROS OMS: You use your stores as an order source. Explore →
Order Sourcing
The logic of deciding which warehouse or store an order is fulfilled from. Criteria such as stock availability, distance to the customer, shipping cost, capacity and service level are evaluated together. A well-built sourcing engine lowers both cost and delivery time.
In HaROS OMS: Rules and Comnous AI route the order automatically to the most suitable warehouse or store. Explore →
Oversell
The situation of selling more products than are actually in stock; it is usually caused by delayed stock synchronization between channels. The result is cancellations, delays and dissatisfaction; it also lowers the seller score on marketplaces. A single, real-time stock source is the most effective measure.
In HaROS OMS: All channels use the same stock data, so the oversell risk drops. Explore →
Product information terms
Concepts that define how the product catalog is structured and how it is distributed to channels.
PIM Product Information Management
Product information management is the system in which product title, description, image, attribute and price data is collected in one center and distributed consistently to all sales channels. It removes the problem of different, missing or conflicting product information in each channel. It is the catalog's "single source of truth".
In HaROS PIM: Product information is distributed from one center to 50+ channels. Explore →
SKU Stock Keeping Unit
The stock tracking code that uniquely identifies every sellable product variant. "Black, size M T-shirt" is a single SKU; other sizes/colors of the same model are separate SKUs. It is the smallest tracking unit of stock, orders and reporting.
In HaROS: SKU is the common key that identifies stock in every module. Explore →
Variant
A version of the same base product that differs by attributes such as color, size or volume. Variant SKUs are grouped under the parent product. A correct variant structure is the basis of correct listing and stock tracking in channels. Complex variant matrices are a typical challenge of retail.
In HaROS PIM: You manage all variants on a single product card. Explore →
Multi-Channel Listing
Publishing a product on multiple marketplaces and e-commerce channels in line with each channel's own format and category rules. Done manually, it is slow and error-prone. A central PIM converts the same product to channel rules and lists it in one move.
In HaROS PIM: You publish a product to all channels from one place. Explore → · Integrations →
Dynamic Pricing
Automatically adjusting price by rules or AI according to variables such as demand, stock level, competitor price and channel. Instead of a fixed price, it balances margin and conversion by keeping price current to conditions. Because it can damage brand perception and margin when applied uncontrolled, it is limited by rules.
In HaROS PIM: Price suggestions are produced with Comnous AI support, within the limits you set. Explore →
Shipping and transport terms
Concepts that define the transport and delivery processes a product goes through on its way from the warehouse to the customer.
TMS Transportation Management System
A transportation management system is software that manages shipment planning, carrier selection, route and cost optimization and delivery tracking. It decides which order goes with which carrier, at the most suitable cost and time. It directly affects logistics cost and delivery performance.
In HaROS TMS: Shipping and carrier processes are in a single module. When the carrier system goes down, HaROS produces its own label. Explore →
Carrier
The courier or freight company that carries the product (domestic courier, messenger, logistics operator). Each carrier differs in price, coverage area, service level and transit time. TMS selects the best-fit carrier per order and integrates label/tracking processes.
In HaROS TMS: Carriers work integrated into the shipping flow. Explore → · Integrations →
Cross-border
Cross-border (international) selling and shipping; it includes customs, tax, currency and international transport processes. It is the basis of selling on international marketplaces and is noticeably more complex than local delivery. A correct document and customs flow prevents delivery delays.
In HaROS: International marketplace flows are ready; customs processes are integrated on a project basis — Explore →
Last-mile
The last leg of delivery: the part in which the product travels from the distribution point to the customer's door. It is usually the most expensive and most visible step of the logistics chain; the stage that most affects customer experience. Route optimization and delivery tracking are critical at this step.
In HaROS TMS: You manage the last mile with carrier selection and delivery tracking. Explore →
Türkiye e-document and tracking terms
The legal electronic document and traceability systems that retail operations in Türkiye must comply with.
e-Invoice e-Fatura
The legal e-document system in which an invoice is issued and delivered to the recipient electronically instead of on paper, over the infrastructure of the Revenue Administration (GİB). It is mandatory for taxpayers exceeding certain revenue thresholds. It speeds up invoicing and reconciliation and lowers archive and error cost.
In HaROS: e-Invoice is connected to operations through integrations and is updated in line with regulation. Integrations →
e-Waybill e-İrsaliye
The e-document type in which the dispatch waybill is issued and delivered electronically. It is the digital equivalent of the legal document accompanying the physical shipment of goods; it is created at the time of shipping and sent to GİB. It digitizes the process between warehouse exit and invoicing.
In HaROS TMS: The e-Waybill is created at the moment of shipping. Explore → · Integrations →
KEP Registered Electronic Mail
The official e-mail system that records the sender, recipient, content and time in a legally provable way. It is used for official notifications and correspondence requiring legal validity; the fact that it was sent cannot be denied. It is the legal guarantee of corporate correspondence.
In HaROS: KEP processes are supported through integrations. Integrations →
İTS Medicine Tracking System
The mandatory tracking system, under the T.C. Ministry of Health, in which medicinal products are tracked end to end by QR code from production to the patient. Every box is uniquely identified; it prevents counterfeiting and makes recall easier. In operations distributing medicines/medical products, every movement is reported to İTS.
In HaROS WMS: QR code and serial number are recorded in every warehouse movement. Explore →
Platform and operations concepts
General terms above the modules that define the platform as a whole.
Fulfillment
Running the whole operational process from receiving an order to packing it and delivering it to the customer (picking, packing, shipping, returns). It is also referred to as "order fulfillment". In HaROS, Fulfillment covers multi-brand warehouse operations and order fulfillment together. A fulfillment center is a facility dedicated to this work, built for speed and volume.
In HaROS Fulfillment: You fulfill orders of multiple brands in the same warehouse, in a single flow. Explore →
Safety Stock
The additional quantity of stock kept as a buffer against demand swings or supply delays. Its aim is to avoid stockouts in unexpected situations. If kept too high it ties up capital, if too low it causes lost sales; the right level is determined with demand forecasting.
In HaROS: Kahin plans safety stock. Kahin analyzes sales, historical data, live stock status and traffic to produce demand forecasts. Explore →
Data Fabric shared data layer
The architecture in which stock, order, customer and product data come together in a single, real-time layer instead of scattered systems. Every module looks at the same current data; the question "which system's number is right?" disappears. Single, current data is the foundation of omnichannel decisions.
In HaROS: All modules run on HaROS Data Fabric, with the same current data.
Composable Adoption
Instead of replacing the whole system at once, the needed modules are added piece by piece on top of the existing infrastructure. The existing ERP is preserved; modules go live step by step. It lowers transformation risk and downtime.
In HaROS: You start with the module you need, without replacing your existing ERP. Comparison →
Operations Platform
A system that manages every part of retail operations such as warehouse, order, product and shipping on a single platform instead of separate software. It solves the integration and data silo problems of a fragmented stack; the whole operation is gathered under a single data layer and a single vendor.
In HaROS: WMS · OMS · PIM · TMS on a single platform, as an operations platform — See HaROS →
