The Delivery Promise Score
On this page, you can read how the delivery promise score is calculated so you know what it means and can take action.
What is the Delivery Promise Score?
Every time a customer visits your item page, we show a delivery promise. The delivery time in that promise forms the basis of the Delivery Promise Score. This score shows, on a scale of 0 to 100, how good your delivery promise has been in the past 56 days.
Delivery Promise Score in the Growth Reward Program
This score shows how good your delivery promise is and is also used in the Growth Reward Program. Participation requires a score of 60 or higher. Do you want to know more about the requirements for the Growth Reward Program?
How do you read your score?
The score is determined by comparing your average delivery time with your target: the promised delivery time that is logical for the type of items you offer.
- Score of 100 = average 1.5 days delivery time
- Score of 0 = average 12 days or longer
- Score of 60 = your target (your score is “sufficient”)
Example:
With a target of 4.8 days, a score of 74 corresponds to an average delivery time of 4.4 days.
Components of the score
Displayed delivery time to customers
The displayed delivery time is the number of expected days until delivery at the moment a customer views your item.
This is influenced by, among other things:
- Time of day (cut-off time)
- Weekdays on which you transfer and on which carriers deliver
- Mandatory holidays
- For Shipping via bol and Logistics via bol: automatic adjustments to fulfill the promise (the Service Framework)

Your average promised delivery time (in days)
We calculate your average promised delivery time over the past 56 days. This is a weighted average based on customer visits, meaning: popular items count more heavily.
There are several ways to arrive at an average result of 2 days. See the examples below.
- Example 1: every customer visit has the same promised delivery time. 100% of all customer visits have a delivery time of 2 days, all 56 days have the same delivery time
- Example 2: customer visits have different promised delivery times. 50% of customer visits have a delivery time of 1 day (next day at home) and 50% of customer visits have a delivery time of 3 days.
The cut-off time of an item also has an influence. For example, for an item with a last order time of 6:00 PM:
- Item viewed at 5:00 PM, delivery time 1 day
- Item viewed at 6:00 PM, delivery time 2 days
Average delivery time (in days): 1.5 days
Expected delivery time per item
Not every item needs to reach a customer equally quickly. Customer expectations for delivery can vary, or options for fast delivery can be expensive. Therefore, we divide items into three groups:
- Long delivery time
- Target delivery time: 6 days
- Product categories: furniture
- Average delivery time
- Target delivery time: 5 days
- Product categories: garden, home decor, construction and sanitary
- Short delivery time
- Target delivery time 4 days
- All other product categories
Your target
The target is the delivery time that is realistic for your type of product range.
We determine this by combining two things:
- How often items from certain groups are viewed
- The expected delivery time per group
This results in a delivery time (in days) to aim for. You do not have to meet the target for every item, as long as your average delivery time is below your target.
Example 1: all your customer visits fall into the short delivery time group
Example 2: your impressions are divided into different groups
How do I improve my delivery promise?
Review items in your seller account and see which items have the most customer visits and the worst delivery time. Do you see room for improvement?
- Then consider using Logistics via bol or Shipping via bol. Partners using these services typically achieve a Delivery Promise score of 60 or higher.
- Prefer to use your own delivery? Then check if you can manage your delivery promise more effectively. You can better align your delivery promise with what you can actually deliver using My Delivery Promise.
Consider adjustments to your logistics process, such as extending your working days, the carrier's delivery days, or a later order cut-off time.
