For a webshop or something else with large volumes, a real iDEAL functionality is of course a must. If iDEAL is only useful because you occasionally send invoices, you can probably also work with the bunq.me functionality. You can create these via profile> bunq.me You can then send personalized links to customers such as bunq.me / your-link-name / amount / description
Please note that commercial / business use of bunq.me and your account (with a premium account instead of business) may not be permitted. In this case, I would always advise you to contact the support team for permission first.
