Frequently asked questions

How does slimzaak automatically invoice my bol.com orders?
You connect your bol.com seller account directly to slimzaak. Every new order is automatically converted into a VAT-compliant invoice, which slimzaak archives right away too. The same works for Amazon, Shopify and WooCommerce.
Are the automatic invoices VAT-compliant?
Yes. slimzaak automatically applies Dutch VAT rules to every invoice, and the OSS scheme for sales to other EU countries. This means every invoice meets the requirements for your VAT return.
What happens with a return?
When a return comes in, slimzaak automatically creates a credit note linked to the original invoice. Your records stay accurate without you having to do anything.
Can I send invoices in my own branding?
Yes. With the template designer, you decide the logo, colors and layout of your invoices. Every automatic invoice is then created and sent in your own branding.
