Leads by fax
You can offer your site visitors the option of sending their requests for quotes (RFQ) by fax using a pdf form or printable page of your site. Some of your customers might prefer using fax to send their initial requests but you should not expect a lot of fax traffic unless faxed quotes are still largely the norm in your industry.
The greatest thing about fax leads is that you can control the layout of the information you need to qualify your leads and help them more quickly. The fax form should include spaces for their name, company, phone, email, address, and line items with quantities, descriptions, etc. The fax form should also contain a space for project descriptions or comments & questions. Add your web address and phone numbers to the top and bottom of the fax form.
Ideally, your visitor will be able to fill out the fax form online (better legibility), print it, and fax it to you. You can also create a form they can print, fill out, and fax to you but expect bad hand writing and drawings (which can be helpful). Use the information on the faxes you receive just like any other lead you get. Call the lead, build a relationship, and discuss their projects, materials, and how you can help them. After your first contact, put the quote together and send it to them. Follow up as usual - quickly.
Aside from a few industries, most companies are moving away from faxes and the rate of that migration is increasing but some of your visitors will appreciate the option and you might get a few orders you would otherwise not have received without a fax lead option.
