Otta's take

Theo Margolius headshot

Theo Margolius

COO of Otta

The cloud has been transformational for Point Of Sales (POS) systems, and in recent years even the smallest of business has been able to accept payments by card. This is because of companies such as SumUp, which since 2012 has been providing POS and payments solutions to any business with a data connection.

SumUp has partnered with many well-known brands, such as MasterCard,, Starling Bank, and Treatwell, just to name a few. Its solution started out with a single card reader but has since grown into a range of devices, online payment services and business accounts. Favoured by over 4 million businesses, it keeps ahead of competitors like Zettle and Square with lower transaction fees and a wider range of payment options.

SumUp has recently claimed the position of largest POS solution provider in Europe, a spot it is holding onto by constantly refining its product. It has released POS Lite and POS Pro in most European markets, serving the smallest and fastest-growing businesses respectively. After a $307 million December 2023 funding round, SumUp will continue to grow its market presence and develop its product range, adding more readers to meet the needs of its rapidly increasing client base.
