Within bol's rules: what's allowed, and what Bkoppeling checks for you
bol has rules on what you can email a buyer and what can appear on an invoice. A violation costs policy points, and bol can deduct them from all your seller accounts under the same KvK number. Below are the rules in bol's own words, with what Bkoppeling does about each one.
No payment details needed. The trial ends automatically.
What Bkoppeling checks for you
A standalone review email
Not allowed by bol “Sending an extra email to the customer with a review request for the item.”
What Bkoppeling does Bkoppeling doesn't send a separate review email. The request is in the invoice email, which is sent automatically just once per shipment.
The request for a review
Allowed by bol “A request for an honest item review on bol (literally mention honest review in the email), provided this request doesn't result in an extra email to the customer.”
What Bkoppeling does The words “honest review” must be in your review request. If they're missing, you can't save the text.
Steering toward stars or offering something in return
Not allowed by bol A review request that “implies giving a 5-star review”, for example with stars or a prize draw or promotion.
What Bkoppeling does Words that steer or reward, such as “5 stars”, “positive”, “discount”, “gift” and “giveaway”, are rejected. You can't save the text with a word like that.
Asking for a review of you as a seller
Not allowed by bol “A request to the customer for a partner/seller review.”
What Bkoppeling does A request like “review our shop” is rejected. The button in the email opens the review page of the purchased item on bol.
Advertising your own store in the email
Not allowed by bol “Sending discount coupons, newsletters or marketing campaigns that refer to your own (web)shop or social media page.”
What Bkoppeling does A web address, the name of a social network or advertising for your own shop in your email text is rejected. A link to bol is allowed.
Your website on the invoice
Not allowed by bol “Placing a link to your website on your invoice as part of your contact details.”
What Bkoppeling does A web address in the texts of your invoice design is rejected: a design like that can't be saved. Your email address is allowed.
Invoice requests
Required by bol bol writes: “invoice requests must be answered within 24 hours”.
What Bkoppeling does With uploading turned on, the invoice is already in the buyer's bol account with the shipment. If a buyer still asks for one, Bkoppeling answers that request automatically with the invoice.
Your bank account number on the invoice
Not allowed by bol “Don't state a bank account number on the invoice.”
What Bkoppeling does A Bkoppeling invoice has no bank account number, and an IBAN you type into a text yourself is rejected. The buyer has already paid via bol.
The language of the invoice
Required by bol The invoice must be in the language of the buyer's country (summarised from bol's explanation of the integration).
What Bkoppeling does The buyer gets the invoice and the email in Dutch or French, depending on the language of their order.
A buyer who returns something
Our own choice bol has no rule for this. This is our own caution.
What Bkoppeling does If a return has been reported for the order, the invoice email is sent without a review request.
The check runs while you write your email text or your invoice design, and blocks saving if it contains anything bol doesn't allow. Right before sending, Bkoppeling checks once more: if your own text no longer passes, the default text is sent instead.
See where you stand in your dashboard
The bol rules page shows, for each rule, whether your email texts and your invoice design are in order, in Dutch and in French. Next to each rule is what bol writes about it.
- Your email text and invoice design, checked rule by rule
- Whether open invoice requests were answered within 24 hours
- What the platform itself takes care of, such as one email per shipment
What you need to watch yourself
Bkoppeling checks your email text and the texts on your invoice. What happens outside of that is in your own hands.
A flyer or packaging with your own web shop
Not allowed: referring to your own web shop or social media in the package or on the box. A flyer with your range is only allowed if it refers to bol.
What you do This is about what you put in the box yourself. A tool can't do anything about that.
Sending a manual or e-book afterwards
Not allowed: “Sending an extra email about the item with a manual.”
What you do You add a manual to your item on bol. Bkoppeling can't send a separate email, so this takes care of itself.
Shipping updates
Not allowed: sending shipping updates yourself, or a separate email with the track and trace, unless the buyer asks for it.
What you do bol keeps the buyer informed itself. Bkoppeling doesn't send shipping emails.
Not an official partner
Bkoppeling is an independent service and is not affiliated with bol. We work with the integration that bol offers every seller, the Retailer API. You create the keys yourself in your seller account and can revoke them there whenever you like.
Buyer data
We use the name, address and email address that bol passes on for the invoice and the email that goes with it, and for nothing else. No newsletters, no advertising.
Peppol for Belgium
bol writes: “Belgian partners must send B2B invoices via structured electronic invoicing.” This has applied since 1 January 2026 and runs via Peppol. Bkoppeling can't do that.
Where this comes from
The quotes on this page were on these bol pages on 7 October 2026. bol may change its rules; what bol itself writes always takes precedence.
- Self-promotion
- Unwanted communication
- Invoice for business customers
- Retailer API: invoices for customers (English)
This is not legal advice. If you're unsure whether something is allowed, ask bol via your seller account.
See the email your buyers receive
In the trial you see the invoice email and the review request before anything goes to a buyer. Also read how the review request in the invoice email works.
