Retailers love Mortar

“We moved from an all-in-one solution to Lightspeed-Shopify integration almost four years ago. I've been extremely happy and have never had a single problem”
Jack Sachs, Owner at Drama Club — Lightspeed + Shopify
“Mortar cut our product and order management time dramatically. Mortar's order distribution and invoicing in Heartland allows my team to save 5 minutes per order.”
Mike Krantz, Ecom Director at Iron and Resin — Heartland Retail + Shopify
“The product works exactly as advertised, the level of documentation is incredible, the customer support is superior. We tried several competitors first, our only regret is that we didn't find Mortar sooner.”
