Our experience, however, is that Vend is more thorough with their features, while Shopify has some marked differences between the plans. For example, you cannot integrate the Shopify POS app with a receipt printer on the Basic plan, but there is no difference between the Vend plans in terms of hardware integration. Staff accounts are also limited on Shopify POS, but not with Vend that has advanced permissions customisation.
Both have good inventory tracking, but Vend does not distinguish between stock at different locations on Lite, only on Pro. Shopify does track stock at several locations even on Basic, but this may be of little use since they do not recommend using Basic Shopify at more than one location (because the features are generally too basic). We can deduce that the inventory features are therefore not as rich on Basic Shopify, while we have seen that Vend has many detailed functions around inventory even on the Lite plan.
Both can register cash payments, process refunds, add taxes and split the tender. Some things like register shifts and gift cards are only available on Shopify and Advanced Shopify, while Vend has these options on all plans.
Whether you’re using Shopify POS on Android or iOS also matters. Some features only work on iPad, so if certain functions are important to you and you use either Android and iPhone, do check that these are available in those apps. You can assume that all Shopify POS’s features relevant to your plan are available in the app for iPad. By default, Vend’s iPad app and desktop software contain all their POS features.
