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 :)
