Moneybird integration

Your Moneybird bookkeeping, filled automatically from every sales channel

Moneybird is an accessible accounting package where you can perfectly well create invoices yourself — slimzaak doesn't change that. What slimzaak adds: orders from bol.com, Amazon, Shopify, and WooCommerce are automatically turned into invoices, receipts are read and processed with AI, and everything is automatically pushed to your Moneybird bookkeeping. You keep booking in Moneybird the way you're used to, without having to retype marketplace orders by hand.

Frequently asked questions

How do I connect slimzaak to Moneybird?
You connect slimzaak to Moneybird via OAuth2: you log in to Moneybird and grant permission for the connection. There's no API key to look up or enter yourself, and the connection is live within a few minutes.
What exactly does slimzaak sync with Moneybird?
After connecting, slimzaak automatically syncs your customers and contacts, your sales invoices as sales entries, and your expenses and receipts — already read automatically by slimzaak's AI scan — as purchase entries. Your VAT return data is also prepared in Moneybird.
Who files my VAT return with the tax authorities?
You or your accountant do, yourselves, from Moneybird. slimzaak automatically prepares the VAT return data in Moneybird, but never files anything with the tax authorities itself.
Why would I use slimzaak if Moneybird can already create invoices?
Moneybird is perfectly capable of creating invoices on its own, and for purely manual invoicing you don't strictly need slimzaak. The difference is automation: slimzaak automatically generates invoices from your marketplace and webshop orders (bol.com, Amazon, Shopify, WooCommerce) and reads receipts with AI, then automatically pushes all of it to your Moneybird bookkeeping. Handy if you sell across multiple channels but still want to keep booking in Moneybird, without retyping everything by hand.
