Thanks for reaching out and posting this question!
You don't have to wait to install Shopify POS onto your iPads and you can import your data at any time. We do have a free app, called QuickBooks Desktop Connector, that we've partnered with Intuit on for helping merchants migrate from QuickBooks POS. That being said, we also have a dedicated QuickBooks Migration Support team and we'd recommend getting in touch with them. They can help you with the migration process as well as check if you're eligible for any promotional programs.
Once you've had a chance to connect with our QuickBooks Migration team, I'd love to hear more about your business and share some resources to help you get started. What types of products are you selling? Do you have a marketing plan prepared for your store?
