The most common ecommerce tickets are variations on four questions: where is my order, can I change it, can I return it, and does this fit or work with that. Answering the first three quickly depends entirely on whether the agent can see the order, the tracking and the customer history without opening another tab.
Gorgias makes that the default arrangement, with store context presented next to the conversation and frequent actions available from the same screen. That shortens handling time and, just as importantly, reduces the mistakes that come from copying an order number between systems.
Zendesk reaches the same outcome through integrations and apps, which is standard practice for a platform that also serves software, travel and financial services. The configuration is more deliberate, and in return you get a workflow layer that can express rules a commerce-first tool is not trying to model.
