We’ve been using Mortar by Accumula to integrate Lightspeed with Shopify, and it’s been absolutely amazing! We’ve tried other systems in the past, and this one has by far worked the best for us.

On top of that, their support team has been incredibly responsive and helpful whenever we’ve run into any issues. We recently completed our full migration to Shopify, and the entire process went really smoothly. Kasia helped us through everything and was always quick to respond to our questions, which made the transition so much easier.

We couldn’t be happier with the experience. Thank you to the entire Mortar by Accumula team, especially Kasia, for all your help!

We couldn't be happier with our experience using Mortar! Nicole consistently goes above and beyond to resolve any technical issues we encounter, always responding quickly and seeing every problem through to a complete resolution. Her knowledge, responsiveness, and dedication give us confidence that we're in great hands.

The level of customer support we've received has been exceptional, and it's clear that the Mortar team genuinely cares about their clients' success. If you're a retailer looking for a reliable platform backed by outstanding service, I highly recommend Mortar. Their commitment to both their product and their customers truly sets them apart.

The app is great but more importantly, the support is excellent. Someone (a real human with a smart brain) responds. The team is awesome and always incredibly helpful. They actually sync gift cards which a lot of the competitors do not. Highly recommend!

I used Mortar for several years and only stopped because I switched from Heartland to Shopify POS, and didn't need it anymore. It was reliable, and once set up, ran without incident. I highly recommend it.

We used Accumula/Mortar for years to connect our Lightspeed and Shopify systems. We appreciated their ease of use, dependability, and their responsive help desk team.

The team at Mortar/Accumula are absolutely fantastic. Seriously, they are so attentive, patient and really make sure any problems I'm having are resolved. But majority of the time things are working smoothly.

The integration software itself makes sending data between our Shopify Store and Lightspeed X-Series very smooth. A few hiccups every so often, but the Mortar team are so helpful. Very happy customer :)
