How fulfilment works step by step: from order to delivery

The clock on the wall reads 11:22. The customer has just clicked the ‘Order’ button. Where will their parcel be in 10 minutes? In an hour? The following morning? And where do you fit into the whole story?

Fulfillment is, at its core, a precisely defined chain of events where every link must function at the right time. If one link fails, the customer will feel it. If they all work, you won’t even know about the logistics – and that is precisely the goal.

In this article, we’ll break down the entire fulfilment process step by step, including what happens behind the scenes, which technologies drive orders, and what happens when an exceptional situation arises.

How does fulfilment work? Fulfilment is a set of processes that automatically trigger the warehouse once an order is received: the system locates the goods, a warehouse worker picks them, packs them, labels them with a shipping label and hands them over to the courier – usually on the same day before the cut-off time.

Step 0: Connecting the e-shop to the warehouse system (integration)

Before the first order is processed, your e-shop must communicate with the warehouse management system (WMS). This is a one-off technical step that is set up once and then runs automatically.

Modern fulfilment centres in Slovakia – including Pack4you – support connections to the most widely used platforms:

• Shoptet, WooCommerce, Shopify – directly via API or plug-in
• Custom solutions – via a universal REST API / XML feed
• Marketplaces – Allegro, Mall and other platforms

Once connected, the system sends every new order to the warehouse in real time. This is the basis for same-day shipping, which today’s customers have come to expect.

Inventory management – the synchronisation of stock levels back to your e-shop works on the same principle. When the last item in stock runs out, the e-shop knows and automatically removes the product from sale.

Step 1: Receiving goods into the warehouse (inbound / stocking)

Every fulfilment relationship begins with stocking. You send the goods to the fulfilment centre – whether from the manufacturer, an importer or your own premises. What happens next?

What happens during goods receipt?

1. Physical inspection of the consignment: The warehouse verifies that the correct number of items has arrived and checks for visible damage. Any discrepancies are recorded and reported to the client.
2. Scanning and registration in the WMS: Each product is assigned a storage location. The system knows that a specific SKU is on shelf B, shelf 3, position 7.
3. Labelling: If the goods do not have barcodes or EAN codes, the fulfilment centre will add them after the client has provided the details. Without barcodes, reliable pick & pack is not possible.
4. Checking expiry dates: For food, nutritional supplements or cosmetics, the expiry date is also recorded to ensure correct FIFO/FEFO dispatch.

Why it matters: Inaccurate stock placement is the root cause of 80% of logistics errors. If the system does not know where the goods are, it cannot pick them correctly.

Step 2: Order receipt and automatic processing

The customer has clicked "Pay". The order flies from your e-shop’s servers directly to the WMS fulfilment centre. The entire transfer takes seconds.

What does the WMS do with the order automatically?

• Checking stock availability: The system immediately checks whether all ordered items are in stock.
• Prioritisation: If necessary, orders can be prioritised – for example, for express delivery or special customer requests.
• Generating a picking list: The WMS automatically generates an optimised route for the warehouse operator so that they can move through the warehouse via the shortest possible route and collect all items.
• Stock reservation: Picked goods are immediately ‘locked’ in the system so that the same item cannot be allocated to another order.

Step 3: Pick – collecting goods from the warehouse

This is the moment when the physical world meets the digital. The warehouse worker (picker) receives an instruction on their mobile terminal or headset: “Go to B-3-7, pick up 2 red T-shirts in size L.”

Picking methods – how it works in practice

• Single order picking: One warehouse worker processes a single order from start to finish. Ideal for bulky items or complex packaging.
• Batch picking: One warehouse worker collects items for multiple orders at once. This saves time when dealing with large volumes of similar goods.
• Zone picking: The warehouse is divided into zones, with each warehouse operator responsible for their own. The order ‘passes through’ the zones and is finalised at the end.

Every item picked is scanned. The WMS verifies that the warehouse operator has taken the correct product and the correct number of items. If the scan does not match, the terminal alerts them to the error before packing – not after delivery to the customer.

Step 4: Pack – order packing

Proper packaging is more than just a box and some tape. It also protects the product, represents the customer’s first physical contact with your brand, and serves as proof of quality.

What does a professional packing process involve?

1. Choosing the packaging: Our experienced team selects the right size of box or bag – based on the dimensions and weight of the contents. The goal is always the same: minimum weight, maximum protection.
2. Filling material: Bubble wrap, paper padding or air cushions, depending on the fragility of the goods.
3. Including documents: Invoice, delivery note, or possibly a gift card or marketing material – all automatically printed by WMS according to the client’s settings.
4. Shipping label generation: WMS automatically selects the optimal courier (based on destination, weight and price), generates the label and affixes it to the parcel.

Branded packaging: If you have your own boxes with a logo, printed tape or include marketing materials, the fulfilment centre will incorporate this into the process. The customer receives an experience of your brand, not from an anonymous warehouse. Pack4you also offers personalisation using stickers with your graphics.

Step 5: Dispatch and handover to the courier (shipping)

The packed parcel is sent to the dispatch ramp, where it is collected by the courier service. This stage has a key parameter: the cut-off time.

The cut-off time is the time by which an order must be in the system to be dispatched on the same day. Thanks to its strategic location in Bratislava, Pack4you ensures a later cut-off time – orders received by midday are dispatched on the same day.

Once handed over to the courier, a tracking number is automatically generated in the system. This is:

• sent to the customer by email or SMS,
• recorded in your e-shop (the customer can see it in their order history),
• recorded in the Pack4you portal for your reference.

The couriers we work with (DPD, SPS, Packeta, DHL and others) collect parcels directly from the warehouse. No trips to the post office, no waiting.

Step 6: Last-mile delivery – delivery to the customer

Last-mile delivery is the final leg of the journey – from the courier’s depot to the customer’s door. It is the most expensive and complex part of the entire chain.

Delivery options that customers appreciate

• Delivery to address (next working day): The standard in Slovakia and the Czech Republic.
• Collection points (Packeta, Z-BOX, DPD Pickup): A cheaper alternative that the customer can collect at their convenience.
• Express delivery (same-day, time-slot): A premium service for urgent orders within Bratislava.
• International delivery: Thanks to contracted rates with carriers, a small e-shop can access prices it wouldn’t be able to negotiate on its own.

Step 7: Returns processing (reverse logistics)

Returning goods isn’t the end of the story – it’s a new chapter. And in a professional fulfilment centre, it follows a precisely defined process.

How is a returned parcel processed?

• Receipt of the returned parcel: The courier delivers the parcel back to the warehouse.
• Checking the condition of the goods: A warehouse worker checks whether the goods are unused, damaged or incomplete.
• Decision based on your rules: Depending on your instructions, the goods are either restocked (if in good condition), marked as B-grade, or sent for disposal.
• Processing the refund: The WMS automatically notifies your e-shop, which can then initiate the refund.

Why this matters: E-shops in the fashion sector see return rates of 20–40%. Without a functional reverse logistics process, every return costs you twice as much.

What happens when something goes wrong? (Exception handling)

No warehouse is perfect. What matters is not whether an exception occurs – but how quickly it is resolved. Professional fulfilment centres have a defined procedure for every situation:

• Item out of stock: The system puts the order on hold and automatically notifies both you and the customer.
• Damaged goods on receipt: Photographic documentation, notification to the client, complaint to the supplier.
• Courier delay: Notification to the customer, or a change of carrier in the event of repeated problems.
• Return of undelivered parcels: A parcel that the customer has not collected or was not at home to receive will be returned to the warehouse and await further instructions.

Technologies driving modern fulfilment

Behind every properly functioning fulfilment centre lies a technological foundation that most e-shops would not even have the chance to build individually:

• WMS (Warehouse Management System): The brain of the entire warehouse. It manages receiving, stock levels, picking, packing and dispatch.
• Barcodes and scanners: Every movement of goods is recorded. No manual counting, no guesswork.
• Integration layer (API): Connects the WMS with your e-shop, couriers and accounting system in real time.
• Reporting dashboard: As a client, you can view the following in real time: stock levels, number of fulfilled orders, error rates and costs.

Real-time timeline: from order to delivery

11:22 – customer places an order on your e-shop 11:22 – order arrives in the Pack4you WMS 12:35 – warehouse staff pick the goods (pick) 12:50 – order packed, label applied (pack) 15:30 – courier collects parcels from the warehouse 16:00 – customer receives an SMS with a tracking number The following morning – parcel delivered

Conclusion: Fulfilment as a system, not a coincidence

The difference between an e-shop that is growing and one that is stagnating is not always down to the product or marketing. Very often, it comes down to logistics – specifically, whether you have a system in place or rely on improvisation day in, day out.

A professional fulfilment process is designed so that every step – from stock replenishment through pick & pack to last-mile delivery – runs predictably, quickly and with minimal errors.
