How can we include a Square payment link to invoices we issue via our cloud accounting system?

We use Freshbooks to issue invoices and would like to use Square as the online card payment system. This will be particularly useful for clients based overseas and using different currencies.  

Can we do this?

I also use Freshbooks, Square is not a partner processor with Freshbooks, but you can just use Freshbooks own credit card processing as it is almost exactly the same rate (except Freshbooks does charge more for American Express).  Also with Freshbooks, your clients can do back transfers at a cheaper rate than credit cards.
