The new invoices with QR code are here

The new PC CADDIE update brings the long-awaited features for the new QR-invoicing, according to ISO 20022. Thus, PC CADDIE has now implemented all the steps to new payment transactions according to the plan. However, the comprehensive conversion to the QR-invoicing will probably not begin until mid-2019. This bill issue in general is still being approached hesitantly, and it continues to work conservatively with the Orange payment slip.
Based on the current timetable, the QR-invoicing becomes mandatory only from June 30, 2020.

This means:
Even if PC CADDIE can already print QR invoices, we recommend that you use today's orange payment slip for the upcoming 2018/2019 year's invoices.
On the one hand, this allows for all payments to be processed as smoothly as possible.
On the other hand, the procedure is not suddenly changed, and your members can adjust to the new QR-invoices.
The settings for the QR-invoicing can be found in our PC CADDIE Wiki: Enjoy reading. If you have questions, feel free to contact us at support (at) pccaddie.com.
