A foreign company (Brazilian; though in the past I&#x27;ve gotten inquiries from other places as well) is interested in purchasing a &quot;licence pack&quot; for my app, whereby I&#x27;d provide a custom build with a few customizations for them to use.<p>When I originally got the email, I replied with a few questions and $ estimate. 
Now they are interested in going forward with the negotiation&#x2F;process.<p>My initial thoughts are to put together a simple contract whereby I assume no liability (ie. the sale is final, non refundable, &quot;as is&quot;), and get paid via PayPal.<p>The sum isn&#x27;t much, ~$2,000 USD.
But I&#x27;m worried about all the weird taxation laws kicking around. Is this something to worry about? Any options&#x2F;suggestions&#x2F;thoughts on how to deal with this?<p>(I understand none of this is legal advice; I&#x27;m located in Canada)
