Why automate ShipStation to Square?
ShipStation to Square automations get more done in less time. Automate the everyday tasks holding back your potential growth.
Push every Shopify order to ShipStation the moment it's placed
When an order comes in, MESA sends it to ShipStation with the right shipping method, carrier, and fulfillment rules already applied. Your team picks up a ready-to-ship order, not a configuration task.
Route orders to the right warehouse based on what's in the cart
When an order contains specific products, a wholesale flag, or a regional destination, MESA reads the details and sends it to the correct ShipStation fulfillment location. Every order reaches the right facility without manual sorting.
Update Shopify the moment ShipStation marks an order shipped
When ShipStation generates a tracking number and marks an order fulfilled, MESA writes the update back to Shopify and triggers any downstream actions — a Klaviyo notification, a customer tag, a loyalty point. Your post-purchase workflow starts the moment fulfillment does.
Sync Square transactions into your Shopify customer records
When a purchase is made in Square — in-store, at an event, at a pop-up — MESA creates or updates the customer's record in Shopify. Your ecommerce and physical sales channels share a single view of every customer.
Keep inventory accurate across Square and Shopify
When a sale is made in Square, MESA updates the corresponding stock level in Shopify. Your online storefront reflects what was just sold in person without a manual sync between your point-of-sale and your store.
Trigger post-purchase workflows from Square transactions
When a customer buys in Square, MESA kicks off the right next step in Shopify — adding a tag, enrolling them in a Klaviyo flow, updating a loyalty record. Your in-person sales feed the same automation as your online ones.
Automate your work in less clicks
MESA makes automation achievable so you can multiply your impact without multiplying the work.
