The most important decision you'll make
Almost everyone starting on Bol.com asks the wrong question. They ask, "How do I sell this product?" when the real question is, "Am I even selling the right product?"
Product choice determines 80% of your success. A great listing for a bad product is still a bad product. An average listing for a good product still sells. This article gives you a systematic method to choose products that actually make money.
The four pillars of a winning product
Every product you consider must score on four criteria. Fall short on even one, and the risk is too high.
| Pillar | Question | Why | |--------|----------|-----| | Demand | Are people actively searching for this? | No demand = no sales, no matter how good your listing | | Competition | Can I break in among existing sellers? | Too many strong players = impossible to rank | | Margin | Do I keep enough after all costs? | Revenue without margin is an expensive hobby | | Logistics | Is the product practical to ship and store? | Fragile, heavy or bulky eats your profit |
Pillar 1: Demand — does it sell at all?
Use Bol.com's own search function
Start in the Bol.com search bar. Type a product term and look at the autocomplete suggestions. These are real searches people enter — free data on what customers want.
Look at review counts on top products
Reviews are a rough but reliable proxy for sales volume. A product with 500+ reviews demonstrably sells. If the top 3 in a category each have hundreds of reviews, there is proven demand.
Rule of thumb: if the bestseller in a niche has fewer than 20 reviews, demand is probably too low — or the niche is so new it's a gamble.
Watch for seasonal patterns
Some products sell year-round (household items, organisers), others spike (garden products, Christmas decorations). A seasonal product can be profitable, but make sure your cash flow can survive the quiet months.
Pillar 2: Competition — can I win here?
The biggest beginner mistake: choosing a popular product where 40 sellers have been fighting over the Buy Box for years. You want demand, but not impossible competition.
The competition sweet spot
Look for niches with:
- Proven demand (top products with 100+ reviews)
- But weak listings (poor titles, short descriptions, few product photos)
A niche where the top sellers have lazy listings is gold. You enter with an optimised listing and overtake them.
Red flags
- A major brand fully dominates the category
- The top 5 sell below cost (price war)
- Bol.com itself (retail) sells the product — hard to beat on price
Analyse what the competitor is missing
Look critically at the listings of the current leaders. Are they missing keywords in the title? Is the description generic? Do they fail to respond to recurring complaints in the reviews? Every gap is your opportunity.
Tip: A free Listing Health Check on a competitor's top product instantly shows where their listing falls short — and therefore where you can win.
Pillar 3: Margin — is there enough left?
Many beginners only calculate cost versus sale price. That's the most expensive miscalculation on Bol.com.
The full margin formula
Selling price
– Purchase price
– Commission (8–17% depending on category)
– Fulfilment cost (FBB or self-fulfilment)
– Storage costs
– Return costs (average % × handling fee)
– Advertising costs (optional)
= Net margin
Concrete example
| Item | Amount | |------|--------| | Selling price | €24.95 | | Purchase price | –€6.50 | | Commission 12% | –€2.99 | | FBB fulfilment | –€2.49 | | Storage | –€0.15 | | Return (7% chance) | –€0.17 | | Net margin | €12.65 (51%) |
Minimum criteria
- Selling price: at least €12–€15 (otherwise fixed costs eat your margin)
- Net margin: aim for at least 35–40% after all costs
- Purchase/sale ratio: ideally buy in for no more than 30% of your selling price
A product with €3 margin per unit looks attractive at volume, but a single return or price correction wipes out your profit.
Pillar 4: Logistics — is it practical?
The perfect product on paper can be a nightmare in practice.
Avoid at the start:
- Fragile products — high damage and return costs
- Very large/heavy items — high shipping and storage costs
- Products with sizes/variants — more complex inventory (clothing, shoes)
- Products with expiry dates — risk of write-offs
- Electronics with warranty claims — heavy customer service
Ideal for starters:
- Small and light (low shipping costs)
- Not fragile
- Single variant (no size/colour complexity)
- Stable, year-round demand
- No brand protection required
Where to find product ideas
- Bol.com bestseller lists — see what's selling well per category
- Search bar autocomplete — direct demand signals
- Reviews of existing products — complaints reveal improvement opportunities ("broke quickly", "too small")
- Your own frustrations — what product did you once search for and couldn't find?
- Trends outside Bol.com — what's popular on social media often comes to Bol.com later
Common mistakes
- Falling in love with a product before checking the numbers
- Going too niche — a unique product with no demand doesn't sell
- Going too broad — competing with major brands on their own turf
- Ignoring margin — focusing on revenue instead of profit
- Skipping a test order — always check your supplier's quality yourself

Frequently asked questions
What is the best product to sell on Bol.com? There's no universal "best" product. The best product scores on four criteria at once: proven demand, beatable competition, a net margin of at least 35%, and practical logistics.
How much money do I need to start on Bol.com? It depends on your sourcing model. With a small initial inventory you can start from a few hundred euros; also budget for EAN codes, packaging and possibly advertising.
How do I know if there's demand for a product? Look at the review counts of the top products in a category and use the autocomplete in the Bol.com search bar. Hundreds of reviews on the bestsellers indicate proven demand.
