Streamlining can easily be achieved by including the right things in your site.
Free up staff by transacting business over the web. Provide answers to commonly asked questions on your site. During busy periods in store, you can direct telephone inquiries directly to your website.
Anybody can answer the phone and direct clients to your website instead of calling on you to answer the tricky questions. Even your staff may learn a few things that they did not know.
Online order forms can also help out by taking your orders for you, even doling out a receipt for the transaction.
