How to Automate Your Bol.com Accounting: A Step-by-Step Guide

As a bol.com seller, orders come in around the clock. Every sale brings its own admin: booking the revenue, applying the correct VAT rate, and later tracing that amount back through your payout. Do this manually in a spreadsheet and it's manageable at ten orders a month — but at hundreds of orders, re-typing everything becomes a full-time job.

On top of that, your bol.com payout is never the same as your revenue. Bol.com deducts commission and offsets costs and returns, so the amount landing in your bank account tells you little about what you actually sold. If you only book the payouts, you'll under-report revenue and miss out on deducting costs separately.

Common mistakes in manual processing:

• booking revenue based on the payout instead of the underlying orders
• forgetting to correct returns in the VAT return
• not recording commissions and shipping costs as deductible expenses
• applying the wrong VAT rate to sales to customers in Belgium

The foundation of automation is a connection between your bol.com seller account and your invoicing software. Through the official API, the software automatically pulls in every new order, including customer details, products, prices, and VAT. Each order is instantly turned into a VAT-compliant invoice, with sequential numbering and your own branding.

That solves a practical problem right away: business buyers on bol.com regularly ask for an invoice, and you need to be able to deliver one quickly. With automatic invoicing, the document is already waiting the moment the order comes in.

A solid connection handles at least this:

• every order becomes an invoice, with no manual action required
• sequential, gapless invoice numbering
• the correct VAT rate per product and per customer country
• automatic delivery of the invoice to the customer, if you want that

The Netherlands has three VAT rates: 21% (the standard rate), 9% (the reduced rate, which applies to items like groceries and books), and 0% (which applies to exports outside the EU, among other things). Your software needs to apply the correct rate per product — get this wrong and your return won't add up, forcing you to correct it after the fact.

Do you also sell to consumers in Belgium through bol.com? That revenue counts toward the EU's €10,000-per-calendar-year threshold for cross-border sales to consumers. Stay under that threshold and you can charge Dutch VAT. Go over it, and you charge the Belgian VAT rate and remit that VAT through the OSS scheme (the Union scheme) via the Belastingdienst.

Good software recognizes the customer's country automatically and applies the right rate, so you never have to work out which VAT applies order by order.

Bol.com pays out on a regular schedule and provides a statement alongside it: which orders were paid out, how much commission was withheld, and which corrections or returns were offset. Reconciliation means matching every line of that statement to an invoice or cost item in your books.

This is exactly the kind of work that takes hours by hand and happens in seconds once automated. The result:

• you see immediately whether the payout matches your sales
• commissions are booked as costs automatically, so you never miss them as a deduction
• discrepancies and corrections stand out right away instead of months later
• your profit per period is realistic, because revenue and costs stay properly separated

If you sell across multiple channels, automatic reconciliation is usually the single biggest time-saver.

Returns come with the territory when you sell on bol.com. From an accounting standpoint, every return is a credit note: a correction to the original invoice, VAT included. Skip processing a return and your revenue sits too high in the books, meaning you remit more VAT than you should.

With an automated connection, every registered return automatically generates a credit note that references the original invoice. The VAT correction then lands in the right period of your return without you having to think about it.

Check whether your software genuinely automates returns. Some tools generate invoices but leave credit notes up to you — which means the error-prone manual work is still there, just moved further down the line.

If you want to genuinely automate your bol.com accounting, check whether a tool can handle all of this:

• a direct bol.com connection through the official API, no manual imports
• VAT-compliant invoices with your own branding and gapless numbering
• automatic credit notes on returns
• reconciliation of payouts with commissions and costs
• VAT overviews you can drop straight into your quarterly return
• support for EU sales and the OSS scheme

slimzaak is built for exactly this: it connects directly with bol.com (as well as Amazon, Shopify, and WooCommerce), automatically turns every order into a VAT-compliant invoice, processes returns as credit notes, and reconciles your payouts with invoices and costs. You can start for free, no credit card required, so you can test with your own orders first and see whether the automation actually does what you expect.
