What are Samples?

What are samples and why are they essential?

What are samples? A sample - also known as a prototype, trial product, or specimen - is a physical example of a product that you, as a seller, receive before placing a large purchase order. Samples form the first and most important step in the purchasing process and protect you from costly mistakes. Whether you're an experienced bol.com seller or just starting out: buying without samples is like sailing blindly into open sea.

In the e-commerce world, and specifically on marketplaces like bol.com, the quality of your products directly determines your success. Customer reviews, return rates, and your ranking are all linked to what you actually deliver. Samples give you the opportunity to check and optimize this beforehand.

The different types of samples explained

Not every sample is the same. Depending on your product phase and goal, there are several types that you can request from your supplier.

Pre-production samples

This is the first physical example that a factory makes based on your specifications. The goal is to check if the design, dimensions, and basic quality meet your expectations. Pre-production samples are often made before mass production starts and are essential for private label products.

Production samples (Golden Sample)

A production sample - also known as the "golden sample" - is the approved reference example. This sample determines the quality standard that all products in the production run must meet. Always keep this sample as a reference for future orders and quality checks.

Existing product samples

If you're purchasing an existing product (not private label), you'll receive a standard example of the product as it's available on the market. This type of sample is common when buying products from wholesalers or via platforms like Alibaba and 1688.

Packaging samples

Often overlooked, but just as important: a packaging sample. On bol.com, customers not only review the product itself, but also the presentation and protection during transport. A damaged package directly leads to returns and negative reviews.

Sample type	Purpose	When to request	Average cost
Pre-production sample	Validate design and specifications	Before mass production	€20–€100 + shipping
Golden sample	Set quality standard	After pre-production approval	Often included
Existing product sample	Test existing product quality	Before first purchase order	Product price + shipping
Packaging sample	Check packaging quality	Along with product sample	€5–€30 + shipping

Why are samples so important for bol.com sellers?

As a bol.com seller, you have to deal with strict performance standards. Your service standard, return rate, and customer satisfaction determine whether you win or lose the koopblok. Samples play a crucial role in this.

1. Quality control beforehand

The most important purpose of samples: you can assess the quality with your own eyes and hands. Photos and descriptions from suppliers rarely give the full picture. Material thickness, color accuracy, finish, and scent - you can only experience these by physically inspecting the product. Without this control, you risk receiving a container full of products that don't meet your expectations.

2. Reduce return rate

Returns are one of the biggest cost factors for bol.com sellers. According to bol.com data, the average return rate in certain categories is over 20%. By testing samples for quality, functionality, and presentation beforehand, you can detect defects before your customers do. This not only saves you money but also protects your sales rating.

3. Better product descriptions and photos

With a physical sample, you can take professional product photos, specify accurate dimensions, and write honest descriptions. This not only reduces returns but also increases your conversion rate. Use the Listing Generator AI to generate convincing product texts based on your sample.

4. Competitive analysis in practice

Don't just request samples from your own supplier, but also from competitors. By comparing products side by side, you can objectively compare quality, packaging, and presentation. These insights help you position and improve your own product.

5. Strengthen your negotiating position

When you provide concrete feedback after receiving a sample - for example, on material, weight, or finish - you show that you're a serious partner. This strengthens your negotiating position for price agreements, Minimum Order Quantities (MOQ), and payment terms.

6. Legal and safety compliance

Products you sell on bol.com must comply with European safety standards. Think of CE marking, REACH regulations, and product-specific guidelines. A sample gives you the opportunity to check if all certifications and markings are correctly applied before you invest thousands of euros.

How to effectively request samples from suppliers?

Requesting samples seems simple, but with the right approach, you significantly increase your chances of getting a quick and useful result.

Step 1: Search and select suppliers

Start by identifying 3 to 5 potential suppliers via platforms like Alibaba, 1688, or European wholesalers. Use the Boloo Product Tracker to research which products sell well and which suppliers other successful sellers use.

Step 2: Create a professional sample request

Always include in your request: the exact product (including specifications), the desired number of samples, your shipping address, and whether you're willing to pay for sample costs. Be specific about color, material, dimensions, and any adjustments.

Step 3: Compare and evaluate systematically

Receiving samples from multiple suppliers? Evaluate them based on the same criteria. Create a scorecard with points for quality, packaging, delivery time, and communication. This way, you make an objective choice instead of a gut decision.

Step 4: Provide detailed feedback

Whether the sample is good or bad: always provide extensive feedback. Send photos of any defects, mention what you like, and specify adjustments for the production run. This process builds trust and leads to a better end product.

Sample evaluation checklist: what to look out for?

Use the checklist below when you receive a sample. Systematically go through each point to ensure you don't miss any details.

Evaluation Criteria	What to Look Out For	Action in Case of Deviation
Material Feel	Thickness, texture, weight, flexibility	Photo + feedback to supplier
Dimensions	Measure everything exactly with a measuring tape or ruler	Refine specifications
Color and Finish	Compare with product photos and specifications	Provide color code or Pantone
Functionality	Test all functions, hinges, buttons, closures	Provide detailed improvements
Packaging	Protection, presentation, labels, barcodes	Discuss packaging adjustments
Odor	Chemical odor may indicate unsafe materials	Request material certificate
Certifications	CE marking, REACH, product safety sheets	Request documentation for import
Delivery Time	How quickly was the sample delivered?	Indication for production time

Common Mistakes When Working with Samples

Even experienced sellers make mistakes in the sampling process. Below are the most common pitfalls and how you can avoid them.

Mistake 1: Only Approaching One Supplier

Always request samples from at least three suppliers. One sample doesn't give you any comparison material. By evaluating multiple options, you'll discover quality differences that you would otherwise miss.

Mistake 2: Refusing to Pay for Samples

Many starting sellers expect free samples. Although some suppliers offer this, you often pay a reasonable fee with serious manufacturers. This is an investment that pays off: buying a bad product costs you much more than €50 in sample costs.

Mistake 3: Not Providing Written Specifications

Discussing orally or sending vague emails leads to misunderstandings. Always send a clear document with all your requirements: dimensions, colors (Pantone codes), materials, weight, and packaging wishes. The more specific, the better the sample.

Mistake 4: Not Keeping the Golden Sample

After approving a sample, suppliers start mass production. If you don't keep the approved sample, you have no reference if the delivered products deviate. Keep the golden sample in a safe place, preferably in the original packaging.

Mistake 5: Ignoring Packaging

On bol.com, the unboxing experience directly affects your reviews. Test not only the product but also how it arrives: is it well protected? Does it look professional? Does it fit in bol.com's standard shipping boxes or LvB?

Samples and bol.com Performance Standards

Bol.com has strict performance standards for sellers. Requesting and carefully evaluating samples helps you meet and maintain these standards.

The most important standards that samples have a direct impact on:

• Return Rate: products that don't meet expectations are returned. Good samples ensure good products and thus fewer returns.
• Customer Satisfaction: positive reviews come from products that deliver what the description promises. That starts with a well-tested sample.
• Product Availability: if your entire batch has defects and you have to stop selling, your availability suffers. Samples prevent this scenario.

Use the Boloo Sales Dashboard to monitor after your first sales period whether your return rate and reviews are in line with your expectations based on the tested sample.

Tips for Working with Foreign Suppliers

Many bol.com sellers purchase from China or other Asian countries. The sampling process with international suppliers has some extra considerations.

• Shipping time: expect 5 to 14 days for sample delivery via express (DHL/FedEx). Plan this in when launching your product.
• Communication: use clear visual references - photos, drawings, 3D renders - in addition to written specifications. This avoids language barriers.
• Import costs: even for samples, customs duties and VAT apply. Take this into account in your cost calculation.
• Quality inspection: consider an independent inspection (such as SGS or Bureau Veritas) in addition to your own sample evaluation for larger orders.
• Seasonal peaks: around Chinese holidays (such as Chinese New Year), factories are closed for weeks. Plan your sample requests well in advance.

Frequently asked questions about samples

What are samples exactly?

Samples are trial examples or specimens of a product that you receive from a supplier or manufacturer. They are used to evaluate the quality, finish, and functionality before placing a larger order.

How much do samples cost on average?

Costs vary greatly per product. Simple products often cost €10–€30 per sample, excluding shipping. More complex products (electronics, custom-made) can cost €50–€200. Many suppliers offset the sample costs with your first order.

Do I always need to request samples?

Yes, always. Even if you've been working with a supplier for a while, it's a good idea to request a sample for every new product line or significant change. Production processes and materials can change without you knowing.

How long does it take to receive samples?

Domestic suppliers: 2–5 working days. European suppliers: 5–10 working days. Asian suppliers via express: 7–14 working days. Custom or pre-production samples can take 2–4 weeks.

Can I get the sample costs back?

Many suppliers offer to offset the sample costs with your first purchase order, provided it reaches a certain minimum amount. Always ask about this before ordering the sample.
