I’m moving our current Squarespace store to Shopify and need the whole process handled end-to-end. Core tasks include exporting every product and collection, migrating only the blog posts that fit the specific dates / categories I’ll supply, and putting clean manual redirects in place—including one that sends all legacy links to the new front page. While you handle the DNS switch, please leave the old site live on a subdomain so we don’t lose traffic during propagation. On top of the standard B2C setup, the same storefront must double as a B2B portal that follows the existing design language. Logged-in wholesale customers should: • See their special B2B pricing automatically • Review full order histories with product names, quantities, dates, statuses and the original payment methods • Be added either by us manually or through a Shopify form you build Shipping needs automation at checkout. Real-time rates from UPS and FedEx have to appear instantly for shoppers, and the workflow should generate printable labels in one click. I’ll purchase the printer—just provide clear step-by-step instructions so the hardware connects correctly. If you’ve already migrated Squarespace content, implemented Shopify Plus/B2B features, and set up carrier integrations, this should be straightforward. Please outline time-frame, preferred apps (if any), and how you’d stage the switch so downtime stays zero.
