Please note:
Qsales API is a powerful accounting integration program, but there is a lot to know in it's setup.
Accordingly we only make the Classic version available for trial since setup is easy and the data from Classic works with API.
We strongly recommends purchasing setup assistance with the API product to ensure you're setup properly from the start, and that your syncing is configured to bring over the data you need.
Setup Assistance is a one-time purchase, and will not be charged at renewal. The quantity of setup assistance must match the quantity of Qsales licensing.
