PostFinance Checkout combines all relevant payment methods and functions on a single platform. The solution also supports retailers in online trading with practical functions, making their everyday work much easier.
Success in online retail not only depends on product range, but also on the shopping experience. This is particularly important during the payment process, where the customer decides if they will complete their purchase or cancel at the last moment. PostFinance Checkout was developed to make this crucial moment as simple and secure as possible. This solution enables retailers to integrate all common payment methods in Switzerland into their online shop, giving customers a modern and convenient shopping experience.
A quick click for customers encompasses a wide range of behind-the-scenes processes for retailers: from payment processing and refunds through to accounting. PostFinance Checkout takes the pressure off retailers in this respect as well, providing them with useful functions and features to make their day-to-day business easier.
One key advantage of PostFinance Checkout is its structure: all payments, refunds and transactions are handled centrally via the dashboard. Retailers see in real time which payments have been received and can directly issue refunds and export reports in just a few clicks. This replaces time-consuming manual processes and creates transparency, which is particularly important in day-to-day business.
Another advantage is acceptance criteria adaptability. The system can be set to only accept Swiss credit cards, for example. This function is particularly interesting for retailers with a purely Swiss customer base who want to avoid fees abroad or minimize fraud risks.
A key feature of Checkout is the automation of recurring processes that would otherwise have to be carried out manually:
This automation reduces the administrative workload considerably. Instead of manually checking transactions or sending receipts, retailers can focus on their core business – their customers, product range and services. Checkout ensures that payments, refunds and notifications are processed reliably in the background each and every day.
PostFinance Checkout is not limited to e-commerce, as the platform can also be combined with payment terminals in high-street retail. This creates an integrated solution for omnichannel payments: customers pay in stores, in online shops or via a QR-bill, and all transactions are centralized via PostFinance Checkout without the need for manual entry.
eBill can also be integrated. Customers who have activated eBill in their e-banking can receive invoices digitally and pay them with a single click. For retailers, this means faster payment processing, less paper and lower error rates.
This combination of online and point-of-sale business enables uniform management of all payments, giving retailers a complete picture of their revenue, regardless of the sales channel. Smaller companies with a mixed business model particularly benefit from this.
PostFinance Checkout offers basic but effective fraud prevention functions. Retailers can set individual rules to reduce risks in a targeted manner. Mandatory activation of 3-D Secure for card payments also helps improve security and prevents unauthorized transactions.
The platform therefore allows for controlled risk management that can be adapted to the needs of the relevant business. PostFinance Checkout uses transparent processes, allowing retailers to decide for themselves which security measures apply. This combination of clear rules, proven authentication procedures and Swiss data protection standards creates a high level of trust for both shop owners and their customers.
PostFinance Checkout processes your payment and customer data in state-of-the-art AWS data centers in accordance with the revised Swiss Federal Act on Data Protection and has a recognized high level of data protection. In combination with the highest PCI standards (Payment Card Industry), which our partners meet, your sensitive information has the best possible protection.
A key advantage of PostFinance Checkout is the transparency of all payment processes. Among other things, the dashboard shows you:
This data can be exported – for further processing in accounting systems such as bexio or Abacus, for example – and serves as a basis for operational planning. This means that simple transaction data can be used to gain valuable insights for developing your range of services: which payment methods are more likely to close a deal? How do payment habits change over the course of the year? And what potential is there to further improve the shopping experience? Checkout gives you data-based answers to these questions.
PostFinance Checkout not only offers retailers a high-performance payment platform, but also provides support tailored to the real needs of everyday business. Technical questions are answered reliably by e-mail and telephone during regular business hours. For critical enquiries, 24/7 support ensures that problems even outside of normal office hours are addressed quickly. The fee-based Support Plus package is available for more complex queries or when quick responses are necessary: e-mails are processed within six hours, a dedicated hotline is available and video sessions provide personal advice on problem solving. PostFinance also offers a wide range of resources to help you get ahead independently: documentation, plug-ins, API instructions and a comprehensive FAQ portal cover common problems.
