About the slimzaak

slimzaak handles your complete invoicing automatically. For every paid or shipped order, the app creates legally correct VAT invoices, sends them directly to your customers by email, and processes refunds as credit notes. VAT and OSS are calculated correctly per country. The app supports multiple sales channels and marketplaces, bundling everything in one place. You can use your own branding, logo, and numbering system. Product and inventory sync keeps your stock updated, while accounting integrations ensure all invoices go straight into your administration. Credit notes are generated automatically for refunds with proper VAT calculations.
Launched: October 5, 2026
