Mortar connects Lightspeed Retail (X-Series) to Shopify and runs them as one — so you sell online and across every location without more to manage. Inventory, orders, products, and customers stay in sync in real time, all from the Lightspeed POS you already use.
Two-time Lightspeed Customer Success Award winner.
Most retailers add a Shopify store and inherit a second business to manage — another system to learn and reconcile. But your Lightspeed POS already does the hard part, so the smart move is to build on it, not replatform: keep working in the POS your team knows while Mortar keeps inventory, orders, customers, and returns in sync across the floor and the web. Adding online adds reach, not a learning curve.
