# Glossary of OTO terms

> Short definitions of the terms used across the OTO docs, from AWB, COD and SKU to hubs, bins and waves, with links to the pages that explain them.

Every term the rest of these docs use, in one list. [Core concepts](https://docs.tryoto.com/get-started/core-concepts.md) explains how they fit together; this is the lookup.

| Term | Meaning |
| - | - |
| **[Account](https://docs.tryoto.com/get-started/architecture.md)** | The outer boundary of your business in OTO. Nothing crosses it. |
| **Area** | A delivery zone drawn geographically, attached to hubs and rules. |
| **[Available](https://docs.tryoto.com/get-started/core-concepts.md)** | Stock that can still be promised to a customer. Falls when an order is assigned to a pickup location. |
| **AWB** | Air waybill — the carrier's shipping label and tracking reference. |
| **[Bin](https://docs.tryoto.com/modules/warehouse-management/inbound-putaway.md)** | A specific location on a shelf, with a type, a capacity and sometimes a preferred SKU. |
| **Box** | One physical parcel. A shipment can contain several, each with its own barcode and weight. |
| **Brand** | A trading identity within one account — logo, sender name, templates and tracking page. |
| **[Branch](https://docs.tryoto.com/modules/hubs-management/overview.md)** | A shop configured as a hub, so it can fulfill and ship orders. |
| **[Carrier](https://docs.tryoto.com/modules/shipping-management/carrier-integration.md)** | The company that carries the parcel. Called a **delivery company** or **DC** in the API and in rules. |
| **Chargeable weight** | What a carrier bills for — the greater of actual and volumetric weight. **Desi** in Türkiye. |
| **City group** | Several cities named together so one rule can reference them all. |
| **[Click and collect](https://docs.tryoto.com/modules/omnichannel-oms/order-fulfillment.md)** | Bought online, collected in a shop, with the handover recorded. |
| **COD** | Cash on delivery. The carrier collects payment at the door and remits it to you. |
| **[Condition](https://docs.tryoto.com/modules/omnichannel-oms/order-routing.md)** | A test against an order — value, weight, destination, brand, tags and much else. |
| **DC** | Delivery company. See **Carrier**. |
| **Delivery option** | One named service from a carrier, such as *Aramex Same Day*. What a shipping rule actually selects. |
| **[Dispatching unit](https://docs.tryoto.com/modules/warehouse-management/packing-dispatch.md)** | A trolley, cage or pallet grouping packed parcels for one carrier's collection. |
| **[Driver](https://docs.tryoto.com/modules/oto-flex/fleet-management.md)** | Someone on your own fleet, working in the OTO FLEX app. |
| **[Feasibility](https://docs.tryoto.com/modules/shipping-management/shipping-automation.md)** | Whether a carrier is eligible at all, checked before selection. A rule can match an order and still find no carrier available. |
| **[Hub](https://docs.tryoto.com/modules/hubs-management/overview.md)** | Anywhere you hold stock and can ship from — warehouse, shop or third-party site. Called a **pickup location** in the API. |
| **Hub code** | The identifier that joins a hub to the same place in your ERP, POS or sales channel. |
| **[incrementId](https://docs.tryoto.com/get-started/core-concepts.md)** | The merchant-facing order number. Kept unchanged when an order syncs from a sales channel. |
| **On Hand** | Stock physically in the building. Falls when goods leave, at fulfillment. |
| **Order** | What the customer bought. Exists whether or not anything has shipped. |

| **[Preparation SLA](https://docs.tryoto.com/modules/hubs-management/overview.md)** | How long a hub takes to get an order ready, in hours. Defaults to 24. |
| **[Proof of delivery](https://docs.tryoto.com/modules/oto-flex/delivery.md)** | What a driver must capture to close a task — a photo, a code, a barcode, or a combination. |
| **[Putaway](https://docs.tryoto.com/modules/warehouse-management/inbound-putaway.md)** | Moving received goods into their bins. |
| **[Role template](https://docs.tryoto.com/platform/users-roles-and-permissions.md)** | A named set of permissions applied to people. One per user at a time. |

| **Serving radius** | How far a hub will deliver, in kilometers. |

| **Short address code** | Saudi national addressing — four letters and four numbers identifying a precise address. |
| **SKU** | The product identifier, and the join between OTO and every other system you run. |
| **[Surcharge](https://docs.tryoto.com/modules/shipping-management/shipping-invoices-reconciliation.md)** | A charge a carrier adds after the fact, usually when a parcel is heavier or larger than declared. |
| **Task** | One stop on a route — a pickup or a delivery. |
| **[User type](https://docs.tryoto.com/platform/users-roles-and-permissions.md)** | What kind of account a person has: Company Admin, Warehouse User, Branch User, Driver User, Customer Service User or Brand Manager User. |

| **[Wave](https://docs.tryoto.com/modules/warehouse-management/picking-methods.md)** | A batch of orders released to the warehouse floor together, so one walk serves many orders. |
| **[Webhook](https://docs.tryoto.com/developers/webhook-events.md)** | An event OTO pushes to a URL of yours, so your systems are told rather than asking. |
| **Zone** | A group of bins, usually an aisle, worked by one picker. |

> [!NOTE]
>
> **Three pairs worth knowing**
>
> **Hub** and **pickup location** are the same object. **Carrier** and **delivery company** (**DC**) are the same company. **Service** and **delivery option** are the same thing — and it is the delivery option, not the carrier, that a shipping rule selects.
>
> Each pair is one name from the dashboard and one from the API. See [Core concepts](https://docs.tryoto.com/get-started/core-concepts.md).
