How long does it take to connect Lightspeed Retail (R-Series) to Shopify?
Most merchants are fully set up in minutes, not weeks. Mortar automatically links existing products by SKU, UPC, or EAN — no store reset or manual matching required.
Does Mortar sync gift cards between Lightspeed and Shopify?
Yes. Gift card balances sync in real time. Customers can buy a gift card in-store and redeem it online, or vice versa.
Can I process Shopify returns, exchanges, and order edits in my Lightspeed store?
Yes. Mortar is the only integration that supports refunds, exchanges, and order edits across channels. It also works with return apps like Loop, Narvar, and Returnly.
Does Mortar work with Shopify Plus?

Will Mortar overwrite my Shopify product descriptions?
No. On Grow and Scale plans, you configure exactly which product fields sync from Lightspeed to Shopify. You stay in control of your online merchandising.
What happens to inventory during high-traffic events like Black Friday?
Mortar includes safety stock thresholds to prevent overselling. High-volume protections are built in for events like Black Friday, Cyber Monday, and product drops.
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 account to get started.
Why doesn't my Shopify sales report match my Lightspeed sales report?
Shopify and Lightspeed calculate sales totals differently — Shopify totals typically include shipping and tax, Lightspeed 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. Our help article walks through how to compare the two reports.
How does Mortar compare to the native Lightspeed eCom integration?
Lightspeed eCom is a separate online store product — it doesn't integrate with Shopify. Merchants who want to run Lightspeed Retail at the register and Shopify online use a connector like Mortar. Mortar is purpose-built for that combination, with real-time sync, multi-location fulfillment, and cross-channel returns that the native option doesn't support.
