// Over 150 Carriers
Do you have an account with a carrier?
AtomicSeller connects to your account (Colissimo, Mondial Relay, DHL, Lettre suivi, and over 150 other carriers worldwide) to generate your labels and retrieve your tracking numbers. All you have to do is print your tracked parcel or letter labels, affix them, and ship!
AtomicSeller offers you direct access to all major French, European, and international carriers, as well as multi-carrier operators such as Ventes Privées, Showroom Privé, Colis Privé, Esendeo, and more.
If your carrier isn’t connected yet, ask us!
// Customs Declarations
You can generate export customs documents such as CN23 and CN22 forms, electronic invoices, pro forma invoices, etc.
Depending on the configuration and the carrier, customs documents can be:
- either printed and attached to the package
- or sent directly electronically to the carrier to streamline customs clearance.


// Return Labels
Generate return labels directly in AtomicSeller.
You can also involve your customers in this process by connecting AtomicSeller to a returns portal or e-commerce module. This way, your customers can return the goods themselves.

Perfect the delivery process
// A single interface regardless of the carrier
Once the shipping services are configured, the method for generating labels is always the same: a single click.
However, it is possible to change carriers (for example, from Colissimo to Mondial Relay) or shipping services within the same carrier (for example, switching from Colissimo without signature to Colissimo with signature).
// Automatic correction of basic data
You can label your packages from your warehouses and stores.
With its automatic data checking and correction (zip codes, cities, accented characters, etc.), AtomicSeller will help you significantly reduce processing and shipping errors.
You’ll save valuable time!



// Package tracking synchronization
AtomicSeller automatically communicates tracking numbers to merchant sites as soon as the carrier picks up the package to inform your customers. This way, they can track the delivery of their package.
AtomicSeller can be configured so that certain carriers notify your customers as soon as their package is available at a collection point.
AtomicSeller can also enable the option for home pickup appointments with carriers that allow it.
// Analyze performance
AtomicSeller offers a range of reports to measure your activity, including the performance of shipping methods, preparation times, tracking numbers, and more.
This way, you can place delivery at the heart of your strategy.
The more efficient your delivery is, the more satisfied customers will be when they receive their order. This will result in more positive online reviews.
