Frequently Asked Questions

Does Mortar work with Lightspeed X-Series?
Yes. Mortar fully integrates Lightspeed X-Series with Shopify and Shopify Plus, syncing inventory, orders, products, and customers in real time across all your locations.
Can I connect multiple Shopify sites to one Lightspeed X-Series account?
Yes. Mortar supports multiple Shopify sites per POS account, so you can run separate storefronts — such as retail and wholesale — from one Lightspeed instance.
Does Mortar support BOPIS with Lightspeed X-Series?
Yes. Customers can shop online and choose which store to pick up from during checkout. Local delivery is also supported.
Can I connect multiple Lightspeed X-Series locations to one Shopify store?
Yes. Mortar supports multi-location setups. Each store manages its own inventory and fulfillment independently.
Does Mortar support Shopify refunds, exchanges, and order edits with Lightspeed X-Series?
Yes. Mortar is the only integration that handles refunds, exchanges, and order edits between Lightspeed X-Series and Shopify — keeping inventory and order history accurate across both platforms.
How long does setup take?
Most merchants are fully set up within 30 minutes, not weeks. Mortar automatically links existing products by SKU, UPC, or EAN — no store reset or manual matching required.
Is there a free trial?
Yes. Mortar offers a 14-day free trial with no store reset required. Install from the Shopify App Store and connect your Lightspeed X-Series account to get started.
Is Vend the same as Lightspeed X-Series?
Yes. Vend was acquired by Lightspeed in 2021 and renamed X-Series in 2022. The product, your data, and your account all carried over. If you're a Vend merchant looking for a Shopify integration, you're looking for an X-Series integration — and Mortar is the most-advanced option.
I migrated from Lightspeed Retail (R-Series) to X-Series — does my Mortar integration still work?
Yes. Mortar supports both Lightspeed Retail (R-Series) and Lightspeed X-Series with the same functionality. When you switch POS products, you'll connect Mortar to your new X-Series account and keep the full feature set.
How does Mortar compare to the X-Series native Shopify integration?
X-Series ships with a free native integration. Mortar is purpose-built and handles capabilities the native one doesn't — including multi-location fulfillment, multiple Shopify sites, order routing, gift card sync, and cross-channel refunds and order edits. See the full comparison →
Why doesn't my Shopify sales report match my X-Series sales report?
Shopify and X-Series calculate sales totals differently — Shopify totals typically include shipping and tax, X-Series often doesn't, and timing differences between online order placement and POS processing can cause day-end mismatches. This is expected behavior, not a sync issue. See how to compare the two reports →
