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.

Always so helpful, Moratar and Accumula has been so helpful for our business. Everyone that works there are so professional and helpful!!! We needed specific help on a new sales channel and they worked with us for days to make it right. So happy we have them .

Excellent technical support once you get the right agent!! System syncing does have issues from time to time, but generally really great connectivity between the apps.

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 :)

This app nearly saved our business! Without this app, our online store would not have been able to so easily integrate with our brick and mortar locations during the pandemic. We require the more robust POS features offered by Lightspeed (as Shopify POS inventory management did not work for us) but Lightspeed's eCommerce solutions did not offer all the features and integrations that Shopify does. Accumula (now Mortar) offers the best of both applications and platforms by nearly seamlessly connecting them. The support team is top-notch. It is refreshing when we reach out to them and they have a deep deep understanding of these apps and software applications--and their quirks and nuances. While not inexpensive, the revenue increase should pay for the app. Highly recommended.

If we could give more stars, we would. Everyone on this team and business has been amazing. Our requirements are very complex, and they have handled them extremely well, with amazing service and detailed consideration.

They answered all our technical questions and requirements and have been a valued addition to our framework,

We recommend them to anyone who requires this app.

Years ago I was faced with the daunting task of building my own website after I paid a web developer to help me make an ecom site. They took my money but never delivered a website. It was literally devastating and I was exhausted. Jeff, from Accumula, was instrumental in helping me get all my products over to shopify from lightspeed. Without this incredible app integration I wouldn't have the website that I have now.

Every single time that I needed support, I got a very fast response. As a small business owner with limited funds and time, this was one of the best experiences that I have had in my 18 years of business.
