Frequently asked questions about Bkoppeling

General
Is this allowed by bol?
Yes. bol offers sellers an integration (the Retailer API) that lets software retrieve orders and upload invoices on your behalf. You create the keys for it yourself in your seller account and can revoke them at any time. You may only ask for a review in an email you're already sending, and only ask for an honest review. That's how Bkoppeling does it. The rules are, in bol's own words, at Within bol's rules.
Is Bkoppeling an official bol partner?
No. Bkoppeling is an independent service and is not affiliated with bol. You connect with two keys that you create yourself in your seller account, not with a "log in with bol" button.
Do I need payment details for the trial?
No. You create an account and can use everything for 14 days. After that the trial simply ends. You only pay once you choose a plan yourself.
How do I connect my bol seller account?
Log in to your seller account at bol and go to Settings, Services, API settings. Under Client credentials, create a new key and copy the client ID and client secret into Bkoppeling. You don't need your bol password and there's nothing to install.
Does it also work with Logistics via bol (LVB)?
Yes. Orders that bol ships for you get an invoice in the same way as orders you ship yourself.
I also sell in Belgium. Is that possible?
Yes. You set the VAT rate per country and per product, and French-speaking buyers get the invoice and the email in French. Note: if you're based in Belgium yourself and deliver to Belgian businesses, that invoice has had to go through Peppol since 2026. Bkoppeling doesn't support that.
I fall under the small business scheme (KOR). Does it work for me too?
Yes. You indicate that you fall under the KOR, and Bkoppeling creates invoices without VAT, with the required note.
Where is my data stored?
In the European Union (Frankfurt). The keys to your seller account are stored encrypted. We only use buyer data for the invoice and the accompanying email.
What happens to my invoices if I cancel?
They remain yours. After cancelling you can keep logging in to view and download them, so you can meet your seven-year retention obligation. This applies to everyone who has had a plan. If you only did the trial and didn't choose a plan, we delete your data 30 days after the trial ends.
I currently use another tool. Can I switch?
Yes. You connect your seller account and switch on automatic processing at the moment you stop using the other tool. Only shipments from then on automatically get an invoice and an email, so no buyer receives two.
Pricing and payment
Do you count the number of orders or invoices?
No. You pay the same amount for ten orders as for ten thousand.
What happens after the 14-day trial?
The trial ends automatically. Nothing is charged, because you haven't entered any payment details. If you don't choose a plan, fetching orders and creating and sending invoices stops. You can still log in and download your invoices. 30 days after the trial ends, we delete your account and your data; you'll get two emails beforehand with the date.
Can I cancel monthly?
Yes. You cancel in your dashboard with one button. You keep access until the end of the period you've paid for: the end of the month for a monthly plan, the end of the year for a yearly plan.
How do I pay?
Through Mollie, with iDEAL or credit card. A monthly or yearly subscription is then charged automatically. You get an invoice for every payment in your dashboard. Lifetime is a single payment.
Are prices including VAT?
No, all prices are exclusive of 21% VAT. Start costs € 12,04 per month including VAT, Pro € 18,09 and Lifetime € 240,79 including VAT.
What exactly does Lifetime mean?
You pay € 199 once and then use everything included in Pro, for as long as Bkoppeling offers the service. There's no subscription and nothing renews. The license applies to one company and one seller account. A second seller account gets Lifetime at half price (€ 99,50, one-time). Modules such as the AI Advisor, the repricer and ads can be added for a fixed monthly amount.
What's the difference between Start and Pro?
With Pro you can turn on the AI Advisor module (€ 14,95 per month per seller account): weekly advice on your prices, reviews, product titles and ads, with a button to apply it, and answers to questions about your own numbers. Everything else (invoices, reviews, margin, reports, notifications) is in all plans, as are the Repricer and Ads modules.
Is paying yearly cheaper?
Yes. Per year you pay roughly ten times the monthly amount, so two months free: Start € 99 and Pro € 149 per year, excluding VAT.
Can I switch to another plan later?
Yes. You switch between Start and Pro in your dashboard; the new amount takes effect at your next payment. If you go back to Start, the AI Advisor stops at the end of your paid period. Switching to Lifetime is also possible: you pay once and your subscription ends. What you've already paid for the current period isn't credited.
I have more than one seller account. What does that cost?
An extra seller account costs half the price of your plan: € 4,98 per month with Start and € 7,48 with Pro, and € 99,50 one-time with Lifetime. You turn modules on per seller account. If you already had extra seller accounts, you keep your old price for them.
AI Advisor
How much does the AI Advisor cost?
It's a module for Pro and Lifetime: € 14,95 per month per seller account, excluding VAT. The first 14 days are free, and during your trial you use it for free anyway. You can cancel monthly.
Which data does the AI Advisor use?
What Bkoppeling already tracks from your seller account: sales and margin per product, your prices, the buy box and competitors' prices, reviews and review requests, your performance at bol and, with the Ads module, your campaigns, keywords and search terms. Buyer data, such as names and addresses, is not included.
Does the AI Advisor change anything at bol by itself?
Only when you click Apply. After that, Bkoppeling checks the advice again against the figures of that moment: for example, a price never goes below what the product costs you. We keep what was there before the change.
Is the AI Advisor included in Start?
No. The AI Advisor is available with Pro and Lifetime. You can switch from Start to Pro in your dashboard; after that, you turn on the module under Modules.
Ads
Which keys do I need?
The ones for bol's Advertising API. You create those separately at bol; the keys for your seller account (the Retailer API) don't work for ads. Your dashboard shows step by step where to find them.
How much does the Ads module cost?
€ 19,95 per month per seller account, with every plan. The first 14 days are free. What you spend on ads at bol, you pay to bol as always.
How often are the figures updated?
Every half hour, Bkoppeling retrieves your campaigns and the figures for today and yesterday; once a day, the last 30 days, the search terms and the winning bid per keyword.
Can I still advertise directly at bol?
Yes. What you change at bol, you'll also see in Bkoppeling after the next sync. You can use both interchangeably.
VAT invoices
Do I have to send a VAT invoice for a bol order?
You must give a business customer an invoice. Any buyer can ask for one via bol, and bol expects you to answer a buyer's request within 24 hours. bol doesn't create that invoice for you: that's the seller's job.
What's on the invoice?
A sequential invoice number, the invoice date, the bol order number and the order date, your company details with KvK and VAT number, the buyer's name and address, and per item the quantity, price and VAT. Your bank account number isn't on it: bol doesn't allow that, and the buyer has already paid via bol.
Can I create the invoice in my own branding?
Yes. You add your logo, choose a colour and a font, decide which columns to show and write your own text at the bottom. You see a preview of the result right away.
How does it work for a return?
As soon as bol reports a return as processed, Bkoppeling creates a credit invoice for the returned items. In your dashboard and in the UBL file, you'll find the reference to the original invoice. You can also credit an invoice manually.
Can I email invoices to business customers only?
Yes. For each seller account, you choose whether every buyer gets an email, only business buyers do, or the invoice is only uploaded to bol. Note: the review request is in the email, so anyone who doesn't get an email doesn't get the request either.
Do older orders get an invoice too?
Not automatically. Automatic processing applies to shipments from the moment you turn it on. For earlier shipments, you create the invoices with one click, per order or for a whole period. No email is sent to the buyer in that case.
What if uploading to bol fails once?
Then Bkoppeling tries again automatically. If it still doesn't work after several attempts, the invoice appears as failed in your list, with the reason and a button to try again.
How do I get the invoices into my accounting software?
With "To my accounting", every invoice is sent automatically to the import address of your accounting software: as a UBL file (e-invoice), as a PDF or both. Moneybird reads the UBL; SnelStart and Yuki read the PDF. You can also download invoices one by one or per period as UBL, as PDF or as a CSV file with all amounts. Bkoppeling does not have a direct API connection with accounting software.
I have multiple seller accounts. Is that possible?
Yes. Each seller account has its own company details, its own invoice numbers and its own settings, and you switch between them with one click at the top. An extra seller account costs half the price of your plan.
Invoice requests
What is an invoice request at bol?
A buyer can ask for an invoice in their bol account, for example because they need it for their records. bol puts that request in your seller account and expects you to answer it with an invoice within 24 hours.
How quickly does Bkoppeling answer an invoice request?
Bkoppeling checks bol every five minutes. If there is a request, the invoice is created if it didn't exist yet and uploaded to bol. A request is usually answered within a few minutes.
What if it doesn't work automatically once?
Then you'll see the request on the Invoice requests page in your dashboard, with the time you have left, and you'll get a notification, by default six hours before the 24 hours are up. You answer it with one button, with a form or with your own PDF.
Does the buyer get an extra e-mail?
No. The invoice is in the buyer's account at bol, and bol lets them know it's there.
Credit invoices and returns
When does Bkoppeling create a credit invoice?
As soon as bol reports a return as processed and the item has actually come back. Bkoppeling checks this every ten minutes and creates the credit invoice for exactly the items that were returned.
And for an exchange?
Not then. With an exchange, the buyer gets a new item and no refund, so the sale stands.
Does the credit invoice go to bol?
No. bol doesn't accept credit invoices. It does go to your accounting software and into your VAT overview, and if you e-mail invoices, the buyer gets it too.
Can I issue a credit myself, for example for a cancellation?
Yes. With the "Credit" button on an invoice, you create a credit invoice for the entire outstanding amount.
Accounting integration
Which accounting software does it work with?
With any software that imports sales invoices by e-mail, such as Moneybird, SnelStart, Yuki, e-Boekhouden.nl, Informer, Exact Online and Twinfield. For each one, we show where to find the import address and which format it reads.
UBL or PDF: which should I choose?
Whatever your software reads best. Moneybird reads the UBL (e-invoice). SnelStart doesn't read a UBL sales invoice yet, but it does read the PDF. Yuki lists PDF as a file format. You can also send both.
Is this a direct connection with my software?
No. Bkoppeling sends every invoice to the e-mail address your software uses to import sales invoices. That's why it works with almost any software, without you having to log in anywhere.
Will my old invoices be sent too?
Not automatically: only invoices created after you turn it on are sent automatically. You can send older invoices in one go per period, up to 1.000 at a time.
VAT
Which VAT rate appears on an invoice to Belgium?
By default, the Dutch rate. If you sell more than € 10.000 a year to consumers in other EU countries, the rate of the buyer's country applies and you file your return through the One-Stop Shop (OSS). You turn this on in Bkoppeling with one switch; from that moment, buyers in Belgium get the Belgian rate.
Can I reverse-charge the VAT to a business buyer in Belgium?
Yes. If you turn this on, a Belgian buyer who has given a VAT number at bol gets an invoice without VAT, stating that the VAT has been reverse-charged.
I sell books or food. Can a product have a different rate?
Yes. You set a default rate per country, and for a product that differs you choose another rate: 9% or 0% for the Netherlands, 12%, 6% or 0% for Belgium.
I fall under the KOR. What appears on the invoice then?
No VAT, but a line stating that you are exempt from VAT. The rates you have set don't apply then.
Does Bkoppeling help with my VAT return?
With the figures, not with the return itself. The VAT overview adds up your revenue and VAT per quarter, per buyer's country and per rate, from your invoices and credit invoices. Always have your return checked by your accountant.
Is this tax advice?
No. Bkoppeling calculates using the scheme and rates that you set. Which scheme applies to your business is determined by your accountant or the Dutch Tax Administration.
Invoice design and email text
Can I put my own logo on the invoice?
Yes. A PNG or JPG up to 2 MB, at the width you choose.
Can I put my web address on the invoice?
No. bol doesn't allow any reference to your own shop on the invoice or in the e-mail. That's why Bkoppeling rejects a web address, social media, a bank account number or a discount code in your texts. Your e-mail address and phone number are allowed.
Can I also customize the invoice e-mail?
Yes. The subject, the text, the review request, the button and the closing, in Dutch and in French. You see the e-mail the way the buyer gets it and send yourself a test e-mail.
Do French-speaking buyers get a French invoice?
Yes. The fixed parts of the invoice and the e-mail are translated. Your own texts on the invoice appear exactly as you typed them.
Product reviews
Am I allowed to ask customers on bol for a review?
Yes, under two conditions. The request must not be in a separate e-mail, and you may only ask for an honest review of the item. That's why Bkoppeling puts the request in the invoice e-mail. You can read the rule in bol's policy.
Can I give something in return for a review?
No. bol prohibits compensation in exchange for a review, as well as steering towards five stars. Bkoppeling rejects a review request containing words such as "discount", "gift", "free" or "5 stars".
Why is the invoice in the same e-mail?
Because bol doesn't allow an extra e-mail in which you ask for a review. You're sending the invoice e-mail anyway, so the request is allowed in there.
How many reviews does it generate?
That differs per product and per price range, so we don't promise a number. In your dashboard you can see per product how many review requests have been sent, how often the button was clicked and how many reviews the product has on bol. A click is not yet a review: we can't see whether the buyer writes one.
How do you measure the clicks?
The button in the e-mail goes through a neutral Bkoppeling link that counts the click and immediately forwards the buyer to the review page on bol. No page from us or from you comes in between. If you don't want that, you turn off tracking and the button goes directly to bol.
Can I customize the text of the e-mail?
Yes. You can customise the subject, text, review request, button and closing, in Dutch and in French. When you save, Bkoppeling checks that the words "honest review" appear in the request and that it contains no words that steer or reward.
Does a customer who returns their order also get the request?
No, if the return has already been reported when the email goes out: then the email is sent without a review request. If you send the email a few days after shipping, that catches most returns.
When is the email sent?
You set that yourself: a number of days after shipping, so the buyer has the item at home before the request arrives. If upload is switched on, the invoice is already in their bol account with the shipment.
Repricer
What is the buy box on bol?
When several sellers offer the same product, one of them gets the "Add to basket" button. That's the buy box. Most customers order from that seller, so whoever has the buy box sells the most.
Do I always win the buy box with the lowest price?
No. bol looks at price, delivery and quality, and according to bol a one-cent difference makes no difference. A repricer helps with price; your delivery time and quality score remain your job.
Does the repricer also raise my price?
Yes, if you've set a maximum. If you're the only seller or a competitor raises their price, your price goes up step by step (by default at most 10% per step), up to your maximum or up to the limit of the number of price stars you choose. Without a maximum, it never raises your price.
Can I set a minimum margin?
Yes. You enter a minimum price, or your purchase price, your shipping costs and the margin you want to keep. Bkoppeling adds VAT and bol's commission and never goes below that minimum.
How do I avoid a price war?
If a competitor drops below your minimum, the repricer doesn't follow. There are also brakes: a waiting time per product, a maximum number of changes per hour, and a pause as soon as the price keeps going down and up against the same seller. You can exclude sellers you don't want to follow.
When is the repricer available?
Now. You switch it on in your dashboard, per seller account. It starts in trial mode: in the log you see what it would do, without any price changing. Trial mode stays free. Actually changing prices is free for the first 14 days; after that you order it on the Modules page.
What does the repricer cost?
The repricer is a module for every plan: € 19,95 per month per seller account, however many products it tracks. The first 14 days are free, and trial mode, in which it only makes suggestions, never costs anything.
Multiple seller accounts
What does an extra seller account cost?
Half the price of your plan, excluding VAT: on Start € 4,98 per month (or € 49,50 per year), on Pro € 7,48 per month (or € 74,50 per year). During the trial period an extra seller account costs nothing.
How many seller accounts can I have?
A maximum of 10, the first one included.
Do I have to set everything up again for the second account?
No. When adding it, you can have your company details, settings, invoice design, email texts and logo copied over. Then you only change what's different, such as the KvK number, VAT number and address. Invoice numbers start at 1.
I have Lifetime. How do I pay for an extra seller account?
Also as a one-off payment: Lifetime for your second account costs half, € 99,50 excluding VAT, and then works for as long as your first one. If you already had extra seller accounts at € 4,95 per month, that stays the same.
Can I remove a seller account again?
Yes. You archive it: fetching and sending stop, you no longer pay for it and the invoices stay viewable. You can always restore it.
Why is this extra important with multiple accounts?
If you break the rules, bol can deduct policy points across all seller accounts under the same KvK number. A mistake in the email of one account then affects the other too. That's why the review request check applies in every account.
Margin per product
How is the margin calculated?
Revenue excluding VAT, minus bol's commission, your purchase price and your shipping and packaging costs, minus returns. The commission is what bol charged per order line.
How do I enter my purchase prices?
Per product, or all at once with a CSV file with the columns ean, purchase price and (if you want) costs, up to 5.000 rows. If you already have purchase prices in the repricer, those are used.
What if I don't have a purchase price for a product?
Then it doesn't count towards profit. It's listed separately with its revenue, so you can see what's still missing.
Are LVB and advertising costs included?
No. bol doesn't pass on the costs of Logistics via bol, ads and return shipments per order, so we can't include them per order.
Reports
Which reports can I get?
A daily report every morning about yesterday, a weekly report on Monday morning about the previous week, and a monthly report on the 1th about the previous month. By default only the weekly report is on; you switch on the others with one click. If nothing happened in a period, you don't get an email.
What's in a report?
Your revenue, number of orders, average order value, returns, invoices created and review requests sent, always next to the previous period. Below that, your best-selling products, with the repricer also how often you won or lost the buy box, and what needs your attention now, such as an open invoice request or a failed upload.
How is the margin calculated?
Revenue excluding VAT, minus bol's commission, your purchase price and your shipping and packaging costs, minus returns. You enter the purchase price per product or add it all at once with a CSV file. A product without a purchase price doesn't count towards profit: it's listed separately, so you can see what's still missing. The costs of Logistics via bol and ads aren't passed on by bol per order, so they're not included.
What is account health?
bol tracks your performance every week: on-time delivery, cancellations, track and trace, returns, customer questions, response time, phone availability and your rating as a seller. Bkoppeling fetches those figures and places them next to bol's standard, with the trend over thirteen weeks and, for each point, what you can do about it. You can see your quality score and policy points at bol itself.
Do the figures match those of bol?
The figures come from the orders that bol passes on to Bkoppeling, and the reports count exactly the same days as the overview in your dashboard. In its own overviews, bol sometimes uses different days or includes cancelled items, so a small difference is possible.
Performance at bol
Which performance figures do I see?
The points that bol measures every week: on-time delivery, cancellations, track and trace, returns, customer questions per item, response to customer questions, phone availability and your rating as a seller. Always next to bol's standard, with the trend over thirteen weeks.
Do I also see my quality score?
No. You see your quality score and any policy points at bol itself. Bkoppeling shows you how you're doing on each service standard and what you can do about it.
How often are the figures updated?
The current and previous week every six hours, because bol is still updating those figures. We retrieve older weeks once.
Will I get a notification if I drop below the standard?
Not yet. You can see it in your dashboard, on the Account health page.
Notifications
What will I be notified about?
Invoice requests that are about to expire or are overdue, invoices that didn't reach bol, invoice e-mails that bounced, a connection to bol that has stopped working or hasn't retrieved anything for hours, and missing company details. If you use the repricer, you'll also get notified about the buy box, new sellers, your minimum price, a price war and your stock.
Will I get e-mails all day long?
No. For each type of notification you choose: an immediate e-mail, inclusion in the daily summary, or no e-mail. If many come in at once, they're combined into one e-mail, and after four e-mails in an hour the rest go to the summary. The same notification about the same product only comes again if it was resolved in the meantime, or after a fixed waiting time per type (for example 6 or 24 hours).
Do I also see the notifications in the dashboard?
Yes. At the top of the dashboard there's a bell showing the number of new notifications, and a notification disappears automatically once the problem is resolved. If there's a notification you don't want to see in the dashboard, you can turn it off.
Can I set when I'm notified about an invoice request?
Yes. bol gives you 24 hours for an invoice request. By default you're notified six hours before that time runs out; you can set that number of hours yourself.
Does this cost extra?
No. Notifications are included in every plan. The notifications about the buy box, prices and stock come from the repricer and you get them if you use it.
Try it yourself
Most questions answer themselves as soon as your first invoice is ready.
No payment details needed. The trial ends automatically.
