Telephone AuditWhat You Do

First, determine if your business qualifies for our service:

  1. Are you spending at least $1,500 per month in telecommunication services?
  2. Does your business have 10 or more phone lines or possess a PBX, Centrex or Key system?

If so, please click here to complete
the account information form.

After you complete the form you will be directed back to this page to complete the rest of the set up process.


Only after the Account Information Form is submitted, you will need to follow all steps in the checklist below.

Client Check List for Audits

We will need the following from you to get started:

  1. Copies of 2-3 months of your latest telecommunication bills from all of your vendors for both voice, data and internet. Generally, summary pages and a few pages of detail, especially international detail is required. Be sure to copy double sided bills.
  2. Copies of any special pricing agreements or term agreement that you may have with any telecommunications vendor.
  3. If you have multiple locations, be sure to include those bills as well. Especially if they are paid out of the remote location. If need be, supply us with a contact and we can make arrangements for the on-site manager to send the information.
  4. Endorsed and dated Audit agreement with Letter of Authority (LOA) copied onto your business letter head.
