Pierre Bågenholm, Operations Manager at reuseIT:
We use Ongoing WMS for all order and inventory management, fully integrated with Fortnox. We now have full control over all the items in the warehouse, which has reduced the handling time for orders/inventory management by about 3-4 hours per day.

Ida Torstensson, Spare Parts Manager at SHIFT Electric Mobility:
The flow of information between the two systems is fast and smooth. On one occasion, we requested a customization that we were sure would add value and increase efficiency for the business. There, Ongoing was able to help us quickly.

Daniel Berglund, Co-founder of Greatlife Group AB:
The connection worked perfectly from the start, without us needing support assistance. Thanks to Ongoings modern and well-documented APIs, it's also easy to build custom functions when we need them.
