Is Training Available?

Each dealership will conduct training with their customers in preparation for the transition. If you would like training, please contact us at:

Can I have someone in my company monitor activity?

Yes, you can have one person in your company act as the purchasing manager and approve all orders before they are transmitted to us. This person will also have the ability to check past orders under our PartStore Document Review online application.

I would like to sign up for What is required?

If you have a Peterson account, you will need your Peterson account number and a valid email address. If you do not have a Peterson account, you will need a credit card and a valid email address.

Who do I contact if I need to change the details of my parts order, such as adding shipping instructions?

Send an email to your e-customer support team

What time do I need to place my order by to have it processed the same day?

Customers in California must place their order by 5:30pm, and customers in Oregon and Washington must place their order by 4:30pm to have it processed that day.

How can the required field “Requested by Date” be utilized to save shipping costs?

Telling us when you need a specific parts order can help Peterson ensure you do not incur excessive freight charges when parts are being sourced outside our home depot. Cat has realigned their distribution strategy with our new “home depot” warehouses now in place in Bakersfield and Spokane. The good news is that there are bigger warehouses closer to you. For more information contact:

Can multiple people have a log in?

Yes, we can set up multiple accounts per company. Each individual user must have their own login.

What if I forget my username or password?

Send an email to your e-customer support team

Can I use a credit card to purchase parts online?

Yes, we accept MasterCard and Visa.

When I access parts information, am I required to enter a serial number before I can continue on to SIS 2.0?

A full serial number is recommended. You can still look up information with a serial number prefix or model number.

I have backordered parts on an order that states "Contact Dealer" as availability. What should I do to ensure I will receive them when I need them?

Please contact the dealer at the phone number provided through the "Contact Dealer" link.
