Plentymarkets & ISR

Payment by invoice is still the most used payment method – also in online shops. A recent study showed again that over 48 % of consumers prefer to choose the payment method invoice followed by credit cards and PostFinance Card. However, the invoice payments bring challenges for the merchants. Besides the counterparty risk there is also the reconciliation effort on how to manage open invoices with payments effectively.

The wallee Plentymarkets Plugin provides you a convenient way to create a compliant ISR invoice (orange inpayment slip), including the possibility to import the V11 / camt.054 / camt.053 files from your bank. These files contain the payments from your clients and all the necessary information to match them automatically with your open invoices. If you like, wallee also offers solutions for all subsequent processes like dunning or legal debt collection. The following blogpost provides you a deep-dive into the usage of ISR payments with wallee and Plentymarkets.

What is ISR (Orange Payment Slips)

ESR (German version) means "Einzahlungsschein mit Referenznummer". In English it means payment slip with a reference number or in short: Orange payment slip. Payments with a reference number are processed automatically and therefore more quickly. ISR makes invoicing and sales ledger accounting easier for you as a merchant due to multiple reasons:

  • Using ISR in Switzerland enables you to simplify the reconciliation process of your paid invoices. There is no manual process needed to match the payment as the reference number contains a checksum and therefore can not be entered the wrong way.
  • Your bank will provide you a file that contains all the payments of the period. This file can be imported and processed. The payments will be matched automatically with your invoices.

Payments through ISR offer many advantages in the handling of invoices for merchants. However, there are also some challenges, which discourage merchants from providing ISR invoices to their clients:

  • Fulfilling the ISR requirements for invoices is not that easy. You do have to create an invoice document that complies with the design rules of the banks. Beside creating the optical character recognition (OCR), parts of the invoices that allow an automated reconciliation process, the elements on the payment slip have to be placed according to very strict standards.
  • ISR payments are a local scheme in Switzerland, therefore it is hard to find existing plugins that are able to comply with the mentioned challenges and requirements above.
  • Beside creating the document you do also need to have the functionality to import the v11 and camt files to match the payments of your clients automatically.
  • The merchant needs also a way to manage open invoices and send out reminder emails or letters or in worst cases to start the debt collection process.
  • Invoices provide besides technical challenges also counter party risks that the client is not paying the invoices. This is why we are working on integrating solvency checks. However, at this moment wallee allows you to provide invoices to returning customers. This means, that only these customers, which order for the second time will see invoice as a payment method.
