Yes and no. Your CPQ software will help you generate a quote, but not every CPQ tool will help you collect payments.
Some CPQ tools, like PandaDoc, come equipped with a payment gateway so that you can quote and bill at the same time.
On the other hand, Salesforce CPQ relies on Salesforce Billing — a completely separate module within the Salesforce platform — to handle payments and invoicing.
Depending on your CRM or ERP system and other solutions in your tech stack, you may need to narrow your search to CPQ systems that include payment gateways if you currently lack that functionality.
