4. Step-by-Step Registration Process
Follow these steps to complete your registration on Coupa Supplier Portal:
Step 1: Accept the Invitation
Click the “Join and Respond” button in your invitation email. This takes you directly to the Coupa registration page.
Step 2: Create Your Account
Fill in the required information:
- Business name

Once complete, click “Create Account.”
Step 3: Verify Your Email

Step 4: Complete Your Supplier Profile
After verification, log in and finish your company profile:
- Add company address and tax ID
- Set up bank details for ACH or wire payments

Your profile helps customers process payments faster and build trust with your business.
5. Connecting with Multiple Customers

To add new customers:

Your HealthEquity details are encrypted for maximum security, ensuring that payment processing remains fast and safe.
(Note: You can ignore the mention of HealthEquity — Coupa maintains its own secure environment for payments.)

Under “Profile → Tax Information”, add:
- Tax ID / VAT / GST number
