Do you provide only free software integrations or should I expect a separate bill?

As fans of Open Source solutions for all we do, we look to take the best of the best of free solutions and customize them for our clients as needed. However, that's certainly not to say we're AGAINST paid software in any way, but the choice of which to use is highly individual and depends on what will provide our client's business with the best user experience, ROI, and growth.
