We cannot offer unlimited creation of QR Codes under a single plan both for technical and commercial reasons.
That said, we can of course create a custom plan for you with a number higher than 500 QR Codes per user (current limit of the White Label Plan).
Please contact us describing your use case, number of QR Codes that you need and other requirements of your project. We will do our best to offer you a custom solution to make it happen.
