Software for Waste Handlers

Bulk Mailing Discounts

Save money at the post office—TRASH FLOW makes it easy.

It's Easy

Many people are intimidated by bulk mailing, but we make it quick & easy with step-by-step instructions. You can expect to spend about 15 minutes more preparing your billing, but you will no longer have to stamp or meter your mail. TRASH FLOW does all the sorting and organizing, prints out the forms and labels, and reminds you when you need to update addresses under the U.S. Post Office CASS service (Coding Accuracy Support System).

It Saves Money

Here are some sample savings:

  • 1000 Post cards per month:  Save $600.00 per year
  • 2000 Post cards per month:  Save $1700.00 per year
  • 1000 Post cards & 500 Statements per month:  Save $1100.00 per year
  • 2000 Post cards &500 Statements per month:  Save $2,250.00 per year

Savings are calculated based on the following:

  • Post Office annual fee:   $200.00
  • TRASH FLOW Address Certification (per update):  $75.00 (if paid by EFT) or $90.00 (if paid by invoice)

The one-time USPS bulk mail permit fee (which eliminates the need to stamp or meter your mail) of $200.00 is not included.


CASS software is already part of your TRASH FLOW system, so there are no additional modules to buy. CASS services are priced on a per-update basis:

  • Setup Charge:  FREE
  • Address Certification (per update):
    • $75.00 (if paid by EFT)
    • $90.00 (if paid by invoice)

Address certification is done over the Internet. It is available 24 hours a day and takes about 10 minutes for the average company with a DSL or cable connection (dial-up connections may take longer).

Intelligent Mail Barcoding

The United States Post Office requires all businesses using the CASS bulk mailing system to have the Intelligent Mail Barcoding (IMB) system no later than Jan 28 2013.

The TRASH FLOW update for IMB is currently available.

Haulers will have to register with the USPS as bulk mailers and we'll provide the instructions on how to do that. Registration with the USPS for this service is FREE.

If you need more information about this new requirement, visit the USPS web site.
