There's not much change in the way I do business.  I'm a sole practitioner based in CA but I set up my business a few years ago to go totally virtual.  I mailed out my paper tax organizers to those who would normally meet face to face and the other half, I sent the Intuit link.  Since the Coronavirus hit, I'm finding that most of the paper organizers want to upload their documents and use the Intuit link.  I also have a portal set up for my clients to send documents that are not related to taxes and I have an appointment scheduler that's automated so my clients choose the time they can meet with me through schedule once.  When I'm done with the return,  we meet on Zoom to review their tax returns and process all of my payments through QBO.
