Third-party e-commerce fulfilment: how we manage order processing and shipping for your shop

Behind every online purchase there is an operational machine that either works — or ruins the end customer's experience. Picking, packing, carrier dispatching, managing seasonal peaks: these are activities that require infrastructure, dedicated staff and well-tested processes.

‍

At LDE, we manage third-party e-commerce fulfilment for companies across multiple sectors, and in this article we explain exactly how our service works in practice.

‍

What e-commerce fulfilment is and when outsourcing makes sense

E-commerce fulfilment refers to the full set of logistics operations that turn an online order into a parcel delivered to the customer: goods receipt, storage, picking, packing, shipping and returns handling. When these activities are entrusted to a specialist external operator, it is called third-party fulfilment or, using the industry term, 3PL Logistics (Third Party Logistics).

‍

In-house management works well enough when volumes are modest and seasonality is flat. As soon as the shop grows — or starts experiencing significant peaks — the fixed costs of warehouse space, staff and technology become a constraint. That is the point at which outsourcing fulfilment stops being an option and becomes a strategic decision: you pay only for what you actually use, you gain access to infrastructure that is already up and running, and you free up time to focus on your core business.

B2B Logistics and e-commerce Logistics: two different worlds

B2C e-commerce Logistics operates on fundamentally different rules from its B2B counterpart. In B2B Logistics, work is typically organised around scheduled orders and delivery windows agreed days in advance. In e-commerce, the time variable contracts sharply: every order is a single unit, arrives without notice and must leave the warehouse within the day.

‍

This difference is not merely organisational — it is structural. It requires a warehouse configured for unit picking rather than pallet picking, a tracking system that updates stock availability in real time, and a workforce accustomed to working in order waves rather than weekly plans. Building this capability in-house only makes sense at certain volumes: below that threshold, partnering with an operator already set up for e-commerce is the more efficient choice.

How our order fulfilment process works

The backbone of our e-commerce order management service is operational discipline around time. Every working day is structured around a 14:00 cut-off: all orders received by that time are processed and handed over to carriers by 15:00, with next-day delivery guaranteed. Orders transmitted after 14:00 roll over to the following working day, without exception — because process predictability is the guarantee that our clients can communicate to their end customers.

‍

Orders arrive in batches throughout the morning and are transmitted to the warehouse at regular intervals. From there, the operational sequence begins: products are located in their storage positions, retrieved via picking, moved to the preparation line, checked, packed to the client's specifications and finally labelled for dispatch.

Final dispatching takes place across multiple carriers in parallel: each shipment is assigned to the most suitable carrier based on destination, weight, dimensions and service requirements. This approach reduces exposure to disruptions from any single carrier and, in most cases, lowers the average cost per shipment compared with a single-carrier contract.

Seasonal peaks and variable volumes: how we keep pace

One of the least-discussed advantages of outsourced e-commerce Logistics is the ability to absorb peaks without requiring clients to scale their own infrastructure to handle them. The final two months of the year — November and December, with Black Friday and the Christmas period — can account for a third of many e-commerce businesses' annual revenue. Managing those volumes with an in-house structure means sizing it for the peak and paying for underused resources for the rest of the year.

‍

At LDE, we work with clients whose seasonality patterns differ from one another: this allows us to balance the operational load across the year and allocate additional resources during each client's peak period, without one peak affecting service quality for the others. For the client, the practical result is a logistics partner that scales with their business: volumes are absorbed without bottlenecks during busy periods, and costs adjust accordingly during quieter ones.

Returns management: the hidden side of fulfilment

In e-commerce fulfilment, returns are not an exception — they are a structural part of the process. In some sectors, such as fashion, return rates can exceed 20–30% of orders. Overlooking this variable when choosing a logistics partner is a mistake that shows up in lead times, costs and the quality of service perceived by the end customer.

‍

Our service includes e-commerce returns management as an integrated component of the workflow: returned goods are received, inspected and classified according to the client's instructions — returned to stock, placed in quarantine or sent for disposal. Each return is tracked and reconciled with the original order, so that warehouse availability remains accurate and reliable at all times. A well-managed reverse logistics process reduces refund lead times for consumers and lowers the rate of unrecoverable products.

Integrations with e-commerce platforms

Third-party e-commerce fulfilment only works if the information flow between the shop and the warehouse is seamless and real-time. This is why our WMS system integrates with the leading platforms — Shopify, Magento and others — automatically synchronising orders, stock availability and shipment status.

‍

Clients have constant visibility over stock and orders without having to query the warehouse manually, and the risk of overselling — selling products that are not available — is eliminated at the source. Shipment tracking is available in real time for both the client and the end consumer, reducing the volume of customer care enquiries about delivery status.
