Yes, it's mostly back-end. We do provide a front-end (a mountable Rails engine), but it's mostly for administrative tasks only (for your support team to handle refunds, chargebacks, upgrades and downgrades, etc.).
Those are pretty important use-cases. If I'm evaluating this vs. Braintree at an early stage, I want to avoid writing my own dashboard software. The only dashboard functionality I care about in the immediate term is refunds, credits, cancellations, and adjustments. If you have this functionality, you should definitely be showing it off. I agree with the grandfather comment that it's unclear you have it. I looked for it and didn't see.
