Vend was the name of the original Vend product that customers use today. In 2020, Vend was acquired by Lightspeed and became Vend by Lightspeed. This is how it appears on the Vend website, and nothing about the features has changed other than that there is better integration with other Lightspeed products. Also, there are no longer processing limits and you can save on your monthly fee by opting for Lightspeed Payments.
Eventually, Vend/ Vend by Lightspeed will be called Lightspeed Series X, as you will see it referred to on the website. Lightspeed Series X will offer the same features that Vend offers now, just under a new name.
