About Sonnar

Inventory and invoicing for second-hand goods trading.

Sonnar is created by Maarten Moerman BV / Camera Obscura Elburg out of a practical need: no proper inventory and invoice management system was available for second-hand goods trading. Sonnar is built to keep daily handling fast, clear, and easy to use.

  • Inventory tracking with quantity-aware invoice generation.
  • Proper support for both margin articles and VAT articles.
  • Trade-in / part exchange flow with automatic inventory insertion for later resale.
  • Multi-user support so colleagues or your accountant can easily review data.
  • Easy backup/import and end-of-year stock snapshot export for tax purposes.
  • Invoice archive, PDF generation, and shipping label flow.
  • Dashboard insights make it super easy to see your revenue and profit per month, year, week, or custom date range.
  • Integrations with major e-commerce solutions (WooCommerce, Wix, Squarespace, Shopify) can automatically create invoices needed for your accounting software flow.
