Things Every Contractor Should Know about Their Supply Partner |  ACHRNEWS

The contracting business revolves around three things: customers, trained workers, and a dependable source of materials. Take any of these away, and the business is doomed to fail. Each of these requires ongoing care and attention. A quick search of this publication’s website points to literally thousands of articles associated with finding and acquiring customers. Similarly, the important subject of employee training and retention gets the coverage it deserves. However, there is only a modest amount about the “care and feeding” of the supply side of the business. READ MORE

I would not know what to do if I didn’t have Evernote to use as a tool for our business. I am the Training Manager for a Commercial Refrigeration company specializing in supermarket refrigeration.
Our service team all have the mobile version on our Android devices. My wife and I both have a premium version to use on mobile as well as our Macs at home.
I share around 10 notebooks with the service techs that have a plethora of information that is crucial to our daily routines, such as passwords, charts, phone lists, store information for each site, remodel notes, etc. Every time I get an email about a particular remodel, I send it to a new notebook that I have created for that remodel store and share it with the tech who handles the daily operations there.
I keep a recurring note called “Monday” where I collect the items that our service team will review when we huddle on Monday mornings to prepare for the week. I keep the bulk of the information in other notebooks and then link it to a bulleted list that we review. Any time during the week that I come across some useful information or think of an issue that needs to be discussed, I just add it to the “Monday” list. It works pretty much flawless.
My wife likes the shared notebook that we share since she handles the finances and every time I use the debit/credit card, I quickly take a snapshot for our shared list so she can always stay on top of our finances.
Yes, Evernote is an essential part of my life and has been for over 4 years. Our company also benefits from the technology and all the service team loves it too.
Attached is a snapshot of my Evernote web with just a few of the many notebooks that I have with nearly 10,000 notes.
