To secure credit card authorizations, use TIS's Travel Services Client Agreement (TSA) or full Terms and Conditions.
Using the TSA:
Execute the TSA.
Enter the authorization amount (credit card vault is for Gold and Platinum members only).
Send for signature.
Ensure TSA links to your website's full Terms and Conditions.
If TSA isn't linked:
Send the full Terms and Conditions for signature and payment authorization.
Best practice is to send the TSA or Terms with each client payment to document all transactions.
For CRM integration, apply the same methodology.
