title: is it advisable to use php for creating a billing system?
body: <p>a client(hotelier) approached  me asking if i could develop a billing and accounts system for his restaurant. and i responded positively. now the only programming languages i am good at is PHP and MySQL. and of course(HTML,CSS &amp; JS). </p>
  
  <p>do you think i should go ahead and build the application using PHP and install it in his system. or else just ask him to find another vendor to build the app.?</p>
  
  <p>thank you</p>
