Support is quick, but very unhelpful. This is not a turn on the service and everything works type app. You need to monitor it because if things stop syncing, and your inventory goes out of wack, they are not proactive, and you will have to reach out to them. We have been paying the
$300 a month for a year, and 7 of those months our website has been all kinds of wrong. When I reached out the response was it's not us, it's you. Some reps are awesome to work with, others don't really seem to care.

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.

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.
