JTL ERP‑Connector

The reviews are sharply mixed, with a strong split between users who are satisfied with the app and those who report serious problems. Positive reviewers say they are generally happy with the system and use it regularly, but still want improvements such as better performance, easier variant booking, and support for multiple locations with separate inventory. These comments suggest the app can be useful in day-to-day operations, especially for merchants who already rely on the JTL ecosystem. The negative feedback is much more intense and focuses on reliability, integration quality, and pricing. Several users say the app does not work at all, mentioning 403 errors, failed activation, poor syncing, and exceptions that break order and inventory synchronization. Others criticize the development pace and feel that important features, such as multilingual support, are missing or delayed. Pricing is also a recurring complaint, with reviewers describing the monthly fee and per-order model as outdated and too expensive for a connector.
