Yes QSL tenders is an absolute SCAM. Steer clear, do not pay them a penny, and note that I feel QSL staff have been directed to find forums like this and post false positive reviews so don't believe anything good about this lot as its either been posted by QSL Tenders themselves or by a complete nutter.

The people at QSL must be quite amoral. Not wrong - because their Ts&Cs probably do stack up, but amoral - and they know exactly what they are doing.

In our case as a new business we signed up to a number of free tender websites including QSL to see how they worked. Like other users we got an invoice out of the blue 2 months later:
- Not a single customer service call in the meantime (unlike every other website).
- Barely clicked on by us (which makes the lack of customer service even more mystifying - do they not care that people don't use the product?).

The invoice had attached to it a screen print of the page where one signed up to it - has anybody ever heard of that?? They know in advance that their customers will not understand why they have an invoice.

Since then they ignored emails - and worse pretended that they had not received them.

Life is too short so we paid up from personal funds as the business does not have the money - but they make my blood boil! AVOID IT!!!
