Hi copycareoffice, thanks for joining this thread and for your support of our desktop product over the years. While the option to create customisable fields for customers is not yet available in QBO UK, we are constantly looking to expand features in our online platform to ensure this meets the needs of all customers, and we'll be sure to pass on your feedback on with our team. If you have any Q's on the discontinuation or transition to Online, please see our article here or get back to us below!
