The website itself usually works. The problem starts after someone clicks send. The request lands in a shared inbox, someone copies the details into the CRM, another person checks the calendar or the stock, and the customer waits for an answer. Every step is a chance for a typing error, a delay or a request that nobody picks up.
Web process automation removes the copying in between. A web form is connected to your CRM, a booking to your planning and invoicing, a webshop to your stock and accounting. The customer gets an immediate confirmation, the record exists in the right system straight away and the follow-up is a task with an owner, not something to remember.
