What is that: Basic Centra concepts and definitions



Account is a company or individual buying Wholesale with a profile stored in Centra. An Account can be represented by several Buyers. Information about the Account is stored where customer information is stored. Examples are: Customer Number, Buyers, Addresses. There are also attributes for segmentation such as Market, Price List and Allocation Rule. Accounts are only used in the Wholesale module of Centra. The corresponding concept in the Direct-to-Consumer module is Customer.


Tool for linking orders to different sources, typically to track sales from social media channels. An Affiliate can use it by inserting a pixel or a code snippet with a specific URL into their own channels. Each call of the URL will create a cookie that identifies the end user and matches with the Affiliate. You have the option to setup the Affiliate URL to include additional attributes and change the amount of days that cookie will be valid.


Specific user role in Centra for agents. The Agent can add Accounts and place orders for Accounts. Agent users have access to both Centra and Centra Showroom. Agents can be configured with a commission percentage which is used to calculate their Commission.

Allocated (stock)

Allocated = Physical - Free To Allocate
The number of said products that are allocated on orders or shipments which are not yet completed.

Allocation Rule

Consists of one or more warehouses sorted by priority. One Allocation Rule can belong to multiple markets, but two groups cannot belong to the same market. With the help of a Allocation Rule, you will set for which markets and stores specific warehouses is used for. Each market has exactly one default Allocation Rule.


Specific data field attached to a Product (General Attributes) or Variant (Variant Attributes). There are standard, predefined and custom attributes. Custom attributes definitions are set up in the Configuration and their values are set up in the Attribute Catalog

Attribute Catalog

This is where the static custom attributes defined in the client configuration are added to then be selectable on the products, variants, orders, customers or accounts. Attributes can be of type boolean, input, multi-line text, drop-down select, image, file or a readonly static. Please note that empty attribute values are not returned in API responses. Attribute catalog is shared by both B2B and B2C stores.

Archived (order status 5)

This order has been archived and will not show up in search results in Centra. Depending on API plugin configuration, it may also be hidden in API responses.

Available = Free To Allocate - Demand + Incoming
The total of said product’s stock including incoming supplier orders.

Available now (stock)

Available now = Free To Allocate - Demand
The quantity available right now of said product.



An order placed when there was no stock. Back-ordering is configured for each Store separately and applies to all products in the store. When an Order is created with back-ordered items, Demand is created. See also: Preorder.

Campaigns are used to set up store-wide price reductions or to set a manual “New in store” flag. It’s important to note that the original price will not be overwritten. Campaigns can be set-up on specific Markets and/or Price Lists. Unlike Vouchers, this logic is applied before checkout process.

Campaign site

A Campaign Site is a way to give selected Customers access to a campaign prior to its launch. This is achieved by assigning the Customer to a Market which they cannot access without going through the campaign site (like VIP Market).

Color Swatch

Taken from the world of fashion, color swatches allow the customer to compare colors, gradients, textures or patterns in a simple manner. In Centra, color swatches can be defined as custom product or variant attributes, usually consisting of color description, hex value and/or small image to show the example texture or pattern.

Completed (order status 4)

This order has completed payment capture and expedited all related shipments. Additional information on shipping details and tracking number can be added when completing each shipment.


Basic configuration settings for Centra are stored in the config file. The config file differs per client and is only accessible for Centra’s front-end agency partners and Centra Support – not for end-users.

Confirmed (order status 2)

This order has been manually confirmed in the Centra admin panel. Only confirmed orders can have a shipment created for them. This step can be skipped by enabling store option “Direct to Shipment”, in which case the checked out order will transfer to status Processing (3) with a shipment created and marked Good-To-Go.



Demand is used with either “Allow backorders” or “Preorder” enabled. Demand will show up in the Order View, Stock View, in the Supplier Module and in some reports. It tells you what you have not yet placed Purchase Order for, and what is the amount you have on open customer orders that are not Allocated.
Demand in the Order overview will include what’s Linked towards Purchase Order, compared to the Stock View where Linked and Demand are separated.

Demand (stock)

The quantity of said product which is on order but not linked to a supplier order or allocated. All products in unshipped orders that are back ordered or on preorder.

Delivery window

Delivery Window (also known as DelWin) is used to manage when products are expected to be delivered. Every B2B order in Centra must belong to one or many Delivery Windows. Products are available for sale once the Delivery Window they belong to has been activated. The Delivery Window normally corresponds with “Order Type” logic in ERP systems. Products in a Delivery Window have available stock based on “Stock”, “Link”, “Stock/Link”, or “Preorder”. Depending on selected option the order will act differently in the way it Allocates Stock, Links towards incoming Supplier Orders, or creates a Demand.


A Discount is a setting for making a reduction off the original price of a product. It can be applied to the price of a single product or the entire order. It can also be configured as a fixed or percentage discount value.


In a display you choose how and where a product should be presented in the front end. You set which market, categories and variant it should be displayed in. You’ll also set the storefront product name in the “display name”. A product without display won’t appear in API responses.

Folders are used to categorize products internally in Centra and used for reporting. One product can belong to at most one folder. When synchronizing data in Centra to an ERP or BI system, it is recommended to maintain the same folder structure, to ensure consistency between reports generated by the different systems. Folders are not to be exposed in B2C sales channels and are not visible in Centra Showroom.

Gift certificate

A Gift Certificate is a way to sell Gift Certificates to your B2C customers. Gift certificates can not be added to the same Selection as Products, hence it will require it’s own checkout. A Gift Certificate will create a Voucher in Centra if there is a purchase made by a Consumer, the value of the voucher will be decided by the value of the Gift Certificate and that is how much the consumer will pay.

Lookbook is a feature in Showroom that allows you to generate a link to products offered in a specific delivery window and display them without prices in order to present products to potential customers.



Markets allow you to segment your store into logical entities. They control which products are available on the website, what campaigns and vouchers are active and which shipping options will be available. In B2C, Market is usually selected based on the end customer geo-location, or it can be set when the customer visits the store via a campaign URL. In B2B, markets can be configured as separate customer groups.

Measurement chart

Used to display the measurements of your products. While Size Charts define product sizes (S, M, L, XL), measurement charts are used to define measurements, in specific units, for each size. For example, measuremement chart for trousers can consist of leg and waist size, defined in cm or inches, for each defined size. This data can be used when displaying products in Showroom.

Order statuses

See Order flow in Centra.


Payment authorization

This is the initial part of the payment, when the payment provider verifies the purchaser has the available funds to cover the transaction, and reserves the funds on the account of the purchaser. The reserved funds often show as "blocked" in the purchaser's account. Payment authotization is enough to complete the payment in Centra and finalize placing the order, payment capture usually occurs later. Payment authorization can be cancelled before capture occurs, but not after.

Payment capture

This is the second part of the payment, when the funds are actually transferred from the account of the purchaser to the merchant account. Payments that have been captured can no longer be cancelled, they should be refunded instead, if needed. Remember, that depending on the Payment Service Provider and the payment method used, there is a maximum time limit between authorization and capture (usually between 14 and 30 days). By default, Centra will finalize the payment capture when the Order is shipped, but you can configure it to capture immediately, or capture manually in the UI.

Payment method

B2B/B2C Payment method in Centra indicates which payment service provider has been used for making a payment. This will be equivalent to which store plugin was used for processing the payment.

A list that contains prices for available products. For each configured store, multiple Pricelists can be defined, each using specific currency and default shipping method, and linked to one or more geo-locations.

For B2B, two prices - Price A and B - are defined for each product, where B is RRP (Recommended Retail Price).

This order has at least one shipment related to it, and at least one of those shipments is not completed. Ordered items can be split into multiple shipments depending on availability and other factors.

Products are split up into variants (i.e. by colour, by style), and each variant is split up into sizes according to the selected size chart. Each Product Variant has to belong to at least one display in order to be searchable and purchasable. One product can be visible in both B2B and B2C depending on how the Displays have been set up. For more details, see Product Model.

Stock Keeping Unit. In Centra the full SKU is built from three different values: main product SKU, variant SKU and size SKU.


In Centra, statics are used to define some of the commonly used parts of the system. For example, e-mail statics can be used to define templates for order confirmations and cancellations. Other statics can define store terms and conditions, or items to be used in the Front End - a static button text or footer content. There are some pre-existing statics, and the customer has the option to add their own. Statics are defined by their name, type and the Store they’re configured for.


Centra can have multiple stores in the same instance. The usual setup is to have two stores - one for B2C and one for B2B. It is however possible to have more than one B2C store if needed. Each Store can have its own plugins configured. Each Store also has its own structure in terms of Brand, Categories, Pricelists and so forth. In a more general term a Store is a separate sales channel. However, if you are to create two Wholesale stores they will share the same invoice number, hence you can not use stores for a multi company setup in B2B/Wholesale if you want to create Invoices.


A Supplier in Centra is from where your products are purchased or manufactured. It’s from a supplier you can create supplier orders and supplier orders can be shown in the Order API for integrations with either supplier or warehouses. It’s on the supplier you add your purchase price/cost price for your products.

From a supplier order you can create one or many deliveries. On a delivery you have the option to add additional cost, meaning you can get a correct landed cost for your products when they are added to your warehouse.

Supplier Order

You can base a supplier order on the demand created from your preorders, additionally you can add over buy to you order, meaning you will have more to sell when you receive the goods from your supplier.



Terms is a section where you setup your incoterms and payment terms to be used for your customers. They are defined as store statics.

A warehouse in Centra is where stock is stored. Warehouse is defined by its name and priority. Each warehouse can belong to one or more Allocation Rules. When stock is added, either by importing a CSV or via stock editor, it always needs to be added to one of the warehouses.
