Use a separate POS location tied to your existing store, stock it with a curated subset of inventory, and test the full payment flow before the doors open. A pop-up is not a new store: it is a temporary location of the store you already have. Set it up that way and inventory, taxes, and reporting stay clean when the pop-up ends.
In Shopify settings, add a new location for the pop-up. This is the step people skip, and skipping it is what creates the mess: sales without a location attribute to the default location, inventory counts go wrong, and unwinding it later is manual. A dedicated location keeps every pop-up sale tagged, every inventory movement tracked, and the teardown as simple as deactivating the location.
Name it clearly with the venue and date, because location names show up in reports forever. "SoHo Pop-Up Sep 2026" beats "Location 2" when you are reading last year's numbers.
Transfer a curated subset of inventory to the pop-up location, not everything. Pop-ups work best with a tight assortment: bestsellers, the products that photograph well, and anything with a story worth telling in person. Transferring your full catalog to a weekend table creates restocking chaos.
Set the quantities deliberately and bring a small buffer. The location's inventory is what POS will sell from, so counts need to be right before doors open. Do a physical count against the transfer: the fifteen minutes this takes prevents the end-of-day reconciliation headache.
Set up the tax rates for the pop-up's jurisdiction. If the pop-up is in a different state or city than your store, the tax nexus and rates may differ, and Shopify will not guess correctly without the location's address. Enter the pop-up address on the location so tax calculation uses the right rates.
For payments, pair and test your card reader before the event, on the venue's wifi and on cellular as backup. Run a real $1 test transaction and refund it. Readers that were fine in the office fail on congested event wifi with depressing regularity. Bring a backup reader if you have one, and know the manual card entry flow in the POS app.
Install Shopify POS on a dedicated device, sign in, and set the pop-up location as the active location. Pin the products you brought to the smart grid so staff are not searching during a rush. Set up the receipt to include your online store URL: the pop-up's real job is acquiring customers, and the receipt is the handoff to the online relationship.
Train staff on the three flows they will actually use: sale, refund, and discount. Pop-up staff are often temporary, and a two-minute rehearsal of each flow prevents the line from stalling while someone figures out the app.
Transfer unsold inventory back to the main location the same day, while counts are fresh. Run the location's sales report and save it: pop-up performance per location is how you decide whether to do it again. Then deactivate the location. Do not delete it: deactivated locations keep their history in reports, deleted ones complicate them.
Follow up with the customer list within a week. Every POS sale captured an email or phone number, and those contacts are the durable asset of the pop-up. A simple thank-you with the online store link converts the weekend's foot traffic into the customer base.
