one of the best jira alternatives out there. we use them and super happy with how this works and by Kevin and Sigurd responsivness to bugs and improvments.
Pricing is calculated depending on various of geomerical parameters - the obvious of these would be volume, weight, bounding box - but it gets more complex depending on the process and material, as well as the local salary of employees in supplier's location.
As a manufacturer, you have your own app that is used as a back office. For example, you can play around with pricing depending on how busy your shop is in a given time.
We vett supplier by working them before and taking them on a test run. Most of our suppliers are used by enterprice companies like IAI, so you can trust us that if you'll get accepted you're in a good comapny :)
In my personal opinion, the biggest advantages to partnering with us as a supplier is that we save significant amount of time on overhead (quoting, payments, communications).
We are exposing all the information about our supplier on our product, limited to what the supplier is willing to share.
For instance, you'll always see certifications and reviews (if exist) to supplies listed on Jiga. But names might be masked due to the supplier request.
We had free shipping worldwide and then got feedback that people want a price breakdown. It make sense to have it on the first page rather later on checkout page. Noted and thanks fot the feedback.
