It offers two card readers – one from BBPOS that is best suited for businesses requiring a lite payments solution – and one from Verifone, which is better for countertop setups.While Stripe does offer some ‘off-the-shelf’ solutions, the software side of the product is primed for those looking for a specialist payment solution.

Frequently Asked Questions Which credit card processing companies are best for small retail businesses? Small retail businesses with lower turnover are best looking at processing payments through a payment facilitator like SumUp or Square. Instead of paying a set amount each month on a contract basis, you pay a small fee per transaction, so when you’re not selling, you’re not paying. Which credit card processing companies are best for small hospitality businesses? Small hospitality businesses are best taking card payments through a payment facilitator. If you’re looking for an all-in-one point of sale and payment taking system, you want to take a closer look at the accompanying software. For example, SumUp POS software doesn’t offer any specific hospitality features, whereas Square's Square for Restaurants product does. Which credit card processing companies are best for ecommerce businesses? Ecommerce businesses should look at super-secure payment gateway providers, including Stripe and WorldPay. While Stripe works on a pay-as-you-go basis, WorldPay charges a monthly fee dependent on your predicted turnover. Both payment gateway providers offer hosted and integrated payment gateway options, meaning ecommerce businesses can choose the type of experience they want to offer their customers when they’re purchasing.
