Connect Sage Business Cloud with slimzaak

slimzaak isn't a replacement for Sage Business Cloud — it's the invoicing and admin tool for your Dutch VAT-compliant invoices and your marketplace orders from bol.com, Amazon, Shopify, and WooCommerce. Connect your Sage account once via OAuth2, and from that point on slimzaak automatically syncs your customers, sales invoices, and expenses into your Sage accounting. Your receipts too — already read automatically by slimzaak's AI scan — land in Sage as purchase entries. That way your accountant keeps working in Sage, while you create invoices and process marketplace orders in slimzaak.
