The Pergola Man operates in the northern suburbs of Perth,

building pergolas and gazebos for private customers. When a customer approaches

him, he visits their house, takes measurements and then discusses possible

pergolas or gazebos which might interest the customer. As a result of this

discussion, the Pergola Man sends the customer a detailed quotation (see

below). The customer may or may not accept the quotation. If the customer

accepts the quotation, the Pergola Man does the work and in due course the customer

is sent an invoice for the work done. The Pergola Man allows part-payments over

six months in order to encourage more business.

The Pergola Man is considering creating a website as a means

of attracting new customers. He anticipates the website will allow customers to

browse examples of his work, browse company details including likely prices and

timescales, email him with a request for a visit and permit (part-)payment of

invoices.  Quotation and Invoices are

sent out via the web site.  Both the Pergola

Man and his customers need to login to use some functions of the site.  When logged in, the Pergola Man can create

and delete users of the web site as well as modify user details such as their

passwords or email addresses.  The

Pergola Man can also send quotations and invoices, as well as use an email form

when logged in.  Customers can log in to

see their invoices.  Customers will use

PayPal to pay invoices via a link on the site. 

They don’t need a PayPal account to pay by credit card.
