How do you move your store to SquareUp without losing your design?

Bring your existing storefront over so it looks exactly like it did, then let the team run underneath it.

Moving stores usually feels like a threat: rebuild everything, hope it looks close, lose a week. It does not have to. Your store comes over as your design, not a template that resembles it, so the move is boring in the best way.

Step 1: point us at your current store
Give us your current store address and we bring the whole thing across, your theme, your fonts, your spacing, your images. You are not rebuilding anything. You are moving in.
Step 2: check it against the original
Open the imported store next to your old one on the same phone and look for anything that drifted. The goal is boring: it should look like the same store, because it is your design, not a look that came close.
Step 3: keep what you sell intact
Your products, prices, and photos come with you. Spot-check a few product pages and your best seller so nothing lost a size, a variant, or an image on the way over.
Step 4: go live when you are ready
Nothing changes for shoppers until you say go. When the store looks like itself and the important pages check out, point your domain at it and open the doors.
