There are many websites where for visitors to make a decision, or more specifically a purchase decision the need a few answers. It might not be possible to provide those answers without input from the customer. A good example is insurance premiums. Customers are usually required to give details such as type of insurance, amount insured, asset type e.t.c Based on these factors insurance companies calculate the premiums for each individual client.

It would be extremely tedious and involve a lot of manual work if these insurance premiums had to be calculated over the phone or the person would have to visit the insurance company’s offices.

A simpler solution around this would be to use a calculated form on their website, where the customer can input their required info and get an instant quote. It saves time, is easier to use and can result in a higher conversion rate.
