How Billink uses InfoX Accounting Integration
Billink is Norway's leading cloud-based sales tool for car, motorhome, motorcycle, and RV dealers. Over half of all car companies' ads on Finn.no use Billink. With over 1000 dealers as customers, they face a major challenge: each dealer uses their own accounting system - from small workshops with Fiken to large car chains with PowerOffice or Tripletex.
Instead of building and maintaining separate integrations for each accounting system, Billink integrates once with InfoX Accounting Integration API. When a dealer chooses their accounting system, InfoX automatically handles the synchronization of sales data, invoices, customer information and inventory information directly to the dealer's accounting. This allows Billink to focus on their core business - making dealers more efficient in sales - while InfoX ensures that integrations with all accounting systems work perfectly.
