I am so glad that I am using Mortar which is the app that I use between my POS system and Shopify. They are awesome to deal with. Their customer service is EXCELLENT. And, if you do a chat with them, you can ask for LIVE SUPPORT and they are there making is so much easier that a BOT. And, if needed, the rep will ask to place a telephone call to you as it may be easier for them to talk vs chat in a message. All companies should offer this. As long as their customer service stays the same there will be no reason for me to look for another company. Again, MORTAR is AWESOME!

Mortar's customer service is terrific. I truly dislike using chat for technical problems but I have to say the reps read, comprehend and ask good questions compared to other companies where I feel like the rep never even read my question. They were able to help me solve the issue and kept the chat open for a few days to make sure the fix worked properly.

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 :)

Mortar by Accumula is the perfect solution for me having Lightspeed for my retail and Shopify for my Eccom. They also have excellent customer service and response times.

Team is really excellent - efficient with their communication, problem solving and collaboration. They hear what you are looking for and work to find a solution for it in the future. They take the feedback in real time to create a better product as we progress together. Highly recommend.

The Mortar team is seriously the absolute best. If we weren’t working so hard to grow our e-commerce and Shopify store we would have stayed with Heartland and absolutely kept Mortar. Thank you again! They offer the perfect amount of customization and are always available to help.

We have been using Mortar for 5 years now. It's nice to know what we only have to update product information in one place (Lightspeed) - It saves us hours. I highly recommend it to anyone who needs the same functionality. Thanks to the Mortar team

Overpriced, rude customer service.

This app works seamlessly and whenever I have had a question it has been answered immediately by a very helpful support staff, at all hours of the day. My past experiences with similar apps have been maddeningly awful. I so happy to have found Accumula / Mortar.
