Klarna Pay Later and Slice it in a custom checkout. When it lifts conversion — and when it only adds a fee.

Send Trustpilot invitations automatically after delivery — and show the rating on your own pages without copy-paste.

Heyloyalty as the mail layer. When an order, booking or membership status changes in your app, the right flow starts — not a nightly CSV dump.

OpenAI integration in Danish business software
GPT in your own system: drafts, classification, search. Not a homepage chatbot. Data, operations, and the jobs that actually save hours.

Create meetings and send mail from the case via Outlook. Without building a new inbox people will not open anyway.
