Disclaimer: I work for Slint

I suppose you are referring to the "Embedded Add-on per application" pricing? At least the non-commercial use is hopefully clear :)

Yes, we need find a better way to show the pricing there since it's dependent on 2 variables - volume and type of embedded system. Maybe some sort of a online calculator?

What exactly is a 'user'? Literally one device running the application? In that case the pricing does seem a bit steep in a small business context.

A user is a person (eg. a developer or a designer etc.) using Slint to build the GUI.

Ahh, it makes this much more reasonable.

The enterprise pricing made me thought at first that the cost is per application user. (Making enterprise lisence more appealing) … of course per end-user pricing would be way too expensive.

We changed the term from "User" to "Seat" and added an entry in the FAQ section to avoid confusion.

Yes, I was thinking of that part, as this kind of stack would make a lot of sense for commercial application.

Just made an appliance using a Web technology for the frontend, as the licensing situation was a nobrainer, and we could focus on delivering value instantly, using proven technology, instead of wasting time on negotiating on terms for something this basic element of the project. I mean if I need an LCD screen of a CPU, I don't negotiate, just go to a retailer, and check their prices and availability, and order&pay. No multiple round interactive sales process needed for something that is just a stock item, no customization needed, etc. Also the per-customer pricing seems potentially a bit discriminatory to me.

So an online calculator would be great, it would instantly let me know if your product suits out business.

For example with the relatively low volume electric part I have mentioned above I had to make several hoops, provide lot of redundant paperwork, and nag the salespeople for weeks to provide me at least a quote the vendor could have already put on their site, as their competitors do. (This vendor has some niche differentiator aspects which made us focus on them first, not on larger volume ones). They wasted a lot of our time and our project was stalled until we got responses from them, and the prices seemed irrationally high, feeling almost as if they didn't want to sell that piece to us from the start. This is what I feel whenever I see Call Us for a quote, as this was not a unique occasion.

I always assumed "call us" pricing was to give a salesperson the opportunity to negotiate the best deal for the seller.

I always read "call us" as "tell us how thick your wallet is".

For early stage products, it's often more like "we have no idea how to price this and we don't want to publish it yet".

You can basically come into those calls and name your price or walk away.

I would think they want to hear what your device sells for. If you're going to charge me $1 per unit on something that costs only three figures, I'm telling you to take a hike.

Qt hasn't quite learned this. Their embedded pricing is absurd.
