The Delivery Promise Score
The Delivery Promise Score shows how attractive your delivery promise is to customers. On this page, you can read how the score works and how you can improve it.
What is the Delivery Promise Score?
For every visit to your item page, we show a delivery promise. This is the number of days within which the customer expects to receive the item. The Delivery Promise Score is based on this promise.
This score is different from delivery time. The score does not indicate whether you fulfill your promise and deliver on time, but rather how attractive your promise is to customers. So, you can always deliver on time and still have a low score if your promised delivery time is relatively long.
How to read your score?
The score ranges from 0 to 100. We calculate it over the past 56 days. We compare your average delivery promise with a target figure.
The target figure is based on comparable items from other partners. It shows what delivery time is logical for your product range.
The score is determined by comparing your average delivery promise with your target figure:
- Score of 100
- Score of 0
- Score of 60
Example:
Your average delivery promise is 4.4 days and your target figure is 4.8 days. This results in a score of 74.
Components of the score
Displayed delivery time to customers
The delivery promise is the delivery time a customer sees on the item page. The actual delivery time is not included in this.
This component is influenced by, among other things:
- The time of order and the cut-off time
- Weekdays on which you hand over and carriers deliver
- Mandatory holidays
- Automatic adjustments of the delivery promise for Shipping via bol & Logistics via bol (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 that items with more customer visits count more heavily.
There are several ways to arrive at an average result of 2 days. See the examples below.
- Example 1: each 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 promise of 1 day (next day delivery) and 50% of customer visits have a delivery promise 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 visited at 5:00 PM, delivery promise shown to the customer is 1 day
- Item visited at 6:00 PM, delivery promise shown to the customer is 2 days
Average delivery promise (in days): 1.5 days
Expected delivery time per item
Not every item needs to reach a customer equally quickly. Customer expectations for delivery may vary, or options for fast delivery may be expensive. Therefore, we divide items into three groups:
- Long delivery time
- Target delivery time:
- 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: 5 days
- All other product categories
Your target figure
The target figure 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 promise in days to aim for. You don't have to meet the target figure for every item, as long as your average delivery promise is below your target figure.
Example 1: all your customer visits fall into the short delivery time group
Example 2: your impressions are spread across different groups
How do I improve my delivery promise?
Review items in the seller account and see which items have the most customer visits and the worst delivery time. Do you see room for improvement?
- Consider using Logistics via bol or Shipping via bol. Partners who use 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, carrier delivery days, or a later order cut-off time.
