Serving heavy equipment operators, fleet managers, and commercial contractors across Northern California, Oregon, and Southwest Washington, Peterson Cat uses a unified digital ecosystem rather than a single isolated webpage. By authenticating with a single Cat CWS account linked to your Peterson Dealer Customer Number, your team gains real-time visibility into local branch parts inventory, custom fleet pricing, VisionLink and Remote Asset Monitoring (RAM) telematics, and Service Information System (SIS) schematics. Whether you are activating a new commercial account or resolving an unlinked store pricing profile, following the exact authentication sequence ensures uninterrupted jobsite operations.

- Billtrust Billing Credentials (For Accounting Teams): A separate Billtrust username and password if your role involves downloading PDF statements or settling balances via the Peterson Electronic Invoicing portal.
- Browser Configuration: An updated desktop or mobile browser (Chrome, Edge, or Safari) with both JavaScript and first-party/third-party session Cookies explicitly enabled to support Caterpillar's Single Sign-On (SSO) token exchange.

Parts Ordering, VisionLink Telematics & Electronic Invoicing

- Peterson Electronic Invoicing (Billtrust Gateway): Accessible via the footer link on https://www.petersoncat.com or https://www.petersonholding.com/electronic-invoicing, allowing accounts payable staff to search historical parts, rental, and service invoices, automate ACH payments, and reconcile monthly statements without paper mail delays.
Fixing Common CWS Login Errors & Account Sync Issues
⚠️ "We can't sign you in: Your browser is currently set to block cookies / JavaScript"
Cause: Caterpillar's unified login service requires active session cookies and JavaScript execution to pass your CWS identity token between cat.com, parts.cat.com, and Peterson Cat's localized dealer database. Strict browser privacy extensions or disabled third-party cookies terminate the handshake.
Solution: Open your browser settings, enable JavaScript, and add [.]cat.com and [.]petersoncat.com to your allowed cookie exceptions list. Clear cached authentication tokens, close all browser tabs, and restart the login flow from https://parts.cat.com.
⚠️ Contract Pricing or Real-Time Branch Inventory Missing After Login
Cause: New CWS registrations default to standard retail guest views until a Peterson Cat e-commerce administrator manually validates and binds your Dealer Customer Number to your CWS user ID, or when no local Peterson branch is selected as the active store.
Solution: Confirm that your nearest Peterson Cat city branch is selected under Select Dealer Store in the top navigation bar. If your commercial account pricing or tax exemption still fails to populate after 24 business hours, call the Peterson Parts & Service Desk at 844-349-4353 to request manual CWS account linking.
⚠️ Verification Code from [email protected] Not Arriving or "This is a username, not a phone number" Alert
Cause: Entering a mobile phone number into the primary CWS username field triggers an input validation rejection. Additionally, corporate email firewalls (such as Proofpoint or Mimecast) frequently quarantine automated verification emails from Caterpillar's central identity server.
Solution: Always enter your exact registered CWS username (usually your business email address) in the sign-in prompt. If awaiting a registration or password reset code, ask your internal IT team to whitelist [email protected] and check your corporate quarantine portal before requesting a new code.
Account Security & Multi-Factor Verification Standards
- 🔒 Verify Official Caterpillar & Peterson Domains: Only enter your CWS credentials on verified URLs ending in .cat.com (such as https://parts.cat.com or https://my.cat.com) and only input billing data on Peterson's authorized Billtrust electronic invoicing portal.
- 🔒 Audit Shared Shop & Field Terminals: Mechanics and parts coordinators frequently log in from shared shop bay workstations. Always click your profile name and select Sign Out after ordering parts to prevent unauthorized purchases against your Cat Commercial Account.
- 🔒 Manage Company Purchasing Limits: Use the administrative controls inside parts.cat.com to assign role-based purchasing limits and order approval workflows for field technicians so large component orders require supervisor sign-off.
- 🔒 Protect Telematics & Remote Start Permissions: Because Remote Asset Monitoring (RAM) and my.cat.com provide GPS equipment locations and remote generator start/stop controls, restrict portal access strictly to authorized fleet personnel and immediately revoke access when employees depart.

Frequently Asked Questions
Q: Can I change my Peterson Cat / Parts.Cat.com username after registering?
No. Once your Caterpillar CWS username is established during Step Ten of registration (which defaults to your email address unless customized during initial setup), it is permanently locked to your identity record. If your corporate email changes, you can update your contact notification email inside your profile settings while continuing to sign in with your original CWS username.
Q: Can I access the Peterson Cat portal from a mobile device or smartphone app?
Yes. You can sign in using your exact same Cat CWS credentials on the official Cat Central app (for mobile parts ordering, QR code scanning, and customer support) and the Cat Inspect app (for digital preventative maintenance walk-arounds), both available on the Apple App Store and Google Play Store.
Q: What is the fastest way to reset a forgotten Peterson Cat portal password?
Go to the sign-in screen at https://parts.cat.com or https://my.cat.com, enter your username, and select the forgot password or Forgot username? recovery link. A one-time verification code will be sent from [email protected] allowing you to establish a new 8-character complex password immediately.
Q: How do I pay my Peterson Cat invoices online?
Equipment parts ordering and invoice payment use two separate logins. To view statements and pay bills online, visit https://www.petersonholding.com/electronic-invoicing (or click Electronic Invoicing in the footer of petersoncat.com) and sign in with your Billtrust username and password. For billing portal assistance, call the Peterson Credit Department directly at 855-204-9817.
