Do you have anything in the works for LightSpeed OnSite, which used to be called LightSpeed Pro, which used to be called LightSpeed, which we call MudSpeed?
I’m sorry, we don't have a full "two-way integration" with Lightspeed OnSite. However, I can offer you a "one-way integration" using a report from Lightspeed. You can read more about this type of integration here:
As you can see, it will update your products and inventory, but it does not send complete orders and customer information back down to Lightspeed. Luckily, updating your catalog is 90% of the work in running a website.
Let me know if you’re interested in this approach. I’m sure there’s an inventory report from Lightspeed that would work. Thanks.
