Short answer. bol gives the buy box to the offer that is best for the customer at that moment: total price including shipping and VAT, delivery, condition, availability and, since 24 June 2026, the quality score. The weighting differs per category. There is one winner at any time; the buy box does not rotate.
What the buy box is and why it matters so much
A bol product page has one "Add to basket" button. The seller behind that button has the buy box. Other sellers sit under "All offers", one click further. In practice the large majority of sales go to the seller in the buy box. Lose it and you usually see it in the same day's revenue.
bol describes it like this: the buy box goes to the partner with the best offer at that moment, judged on price, delivery and quality. There is no fixed point at which you have done "enough". When a competitor improves their offer, the buy box moves.
The five factors bol names
| Factor | What bol says | What you control |
|---|---|---|
| Availability | The item must be deliverable right away. | Keep stock up to date, never let it run to zero. |
| Condition | New, refurbished, second-hand and returned items are weighed. | Sell new where you can; list second-hand separately. |
| Price | The total price including shipping and VAT counts. A difference of €0.01 has no effect. | Include shipping in the sum; do not chase cents. |
| Delivery | Faster is better. bol also looks at the cut-off time ("ordered before 23:00, delivered tomorrow") and whether the customer can pick a later delivery slot. | Late cut-off, Shipping via bol or Logistics via bol, delivery options switched on. |
| Quality score | Five service standards over 22 weeks, scale 0–100. Minimum 65; extra benefits from 70. | Deliver on time, few cancellations, track & trace, handle returns and customer questions properly. |
Important: the weighting is not the same everywhere. bol's own example is that fast delivery weighs heaviest for everyday items, while for furniture the price is usually decisive. bol keeps adjusting that weighting based on customer behaviour. That is why a tactic that works in one category does nothing in another.
What changed on 24 June 2026
Until that date the old performance score counted in the buy box. Since 24 June 2026 it is the quality score. It measures over 22 weeks instead of 6, looks at five standards instead of three (returns and customer questions are new) and counts every shipment. The score is shown per shipping method in your seller account: own shipping, Shipping via bol and Logistics via bol. bol has announced that it will later use those sub-scores for the buy box as well.
The practical consequence: a bad week no longer drops out of your score after six weeks. A problem with returns or unanswered customer questions now counts, and stays visible for more than five months.
Six things you can do yourself
- Calculate with the total price. An item at €24.95 with €2.99 shipping competes at €27.94, not €24.95. Free shipping above a threshold changes the comparison per item.
- Sharpen your delivery promise. A cut-off at 23:00 instead of 16:00 is a better offer in bol's eyes, even at the same price. Shipping via bol or Logistics via bol strengthens the promise; bol does not attach a fixed percentage to it.
- Keep the quality score above 70. Then you also qualify for Select deals. From 75 you no longer get a strike for an occasional missed delivery promise.
- Watch your stock per EAN. Sold out means no buy box. If you connect a webshop, let stock sync automatically.
- Do not chase €0.01. bol says literally that such differences have no effect. Small price cuts make sense until you have the buy box back, and not after.
- Measure per item. Because the weighting differs per category, an experiment beats a general rule: change one factor, watch for a few days, and record what it did.
Common mistakes
- Looking only at price while the competitor delivers faster. In many categories delivery wins.
- Cutting the price to win back a lost buy box when the cause is a fallen quality score. Then you pay margin for a problem that sits elsewhere.
- Forgetting that returns and customer questions count since June. A slow reply to questions now costs buy box chances too.
- Waiting until the score drops below 65. With a structural score of 64 or lower you get a warning and four months to improve; after that bol can close the account.
When automation helps
Once you have more than a few dozen items, tracking by hand who has the buy box and at what price is no longer feasible. A repricer watches the buy box status per item and adjusts the price within a floor and ceiling you set. Start in dry-run: let the software show for a week what it would do, check the proposals, and only then switch on live repricing.
