However, with SumUp Air, users have greater control over their expenses as they are only charged for the services they use. This transparent approach aligns with the needs of small businesses that value cost-effective solutions.

While SumUp Air excels in terms of cost transparency, it is essential to acknowledge that it may not provide the most robust range of features compared to some of its pricier competitors.
