Modifiers that survive the trip
Latte sizes, milk types, syrup shots — your Square modifier sets pass straight through to Shopify as a single product, no 3-option cap. No bolt-on options app that doesn't talk to Square; one sync engine handles both.
For Square sellers opening on Shopify
From Square to Shopify, without the stop.
Coffee · retail · specialty food · maker shops — wherever modifiers and real-time stock matter.
Cross-docking for your data: a sale hits Square and stock clears at the bay in seconds — webhook-driven, not a polling cadence. Modifier sets survive the trip.
Starts free · Pro $19/mo · App Store listing link goes live at launch.
What Crossdock moves
Webhooks, not 3-minute polling
Your register rings; your storefront updates. Stock clears at the bay in seconds — not on a fixed cadence that lets overselling slip through.
See it before you sync it
Dry-run preview shows every product, price, and image change before the first write. One-click rollback if it's wrong — your Shopify catalog is never overwritten by a setting you didn't read.
