< payment integration >
Modern customers expect a wide range of payment options – from PayPal and credit cards to “Buy now, pay later” models. To succeed in digital commerce, companies need to support multiple payment service providers (PSPs) while ensuring that all payment flows are seamlessly connected to existing systems such as webshops, ERPs or accounting tools.
A centralized payment integration delivers exactly that: it automates payment processes, enhances data security and significantly reduces administrative effort – whether in B2C or B2B environments.
