Zapier allows you to connect your apps and automate your workflows. Each connection you create is called a Zap. It is commonly used to automate repetitive tasks without having to learn a single line of code.
Apps include Facebook, Gmail, MailChimp, and even TrekkSoft; while a workflow is a series of actions that happen in a specific order. A workflow therefore begins with a trigger action.
Say you want to create an invoice for each booking, you can easily set that up with Zapier. Here, your Zap is the connection between your booking software and your accounting software, your trigger is a new booking received via TrekkSoft's booking system, and the workflow is the task of creating an invoice.
