"I have been working with Reckon API/SDK to help many of my clients to integrate different products of Reckon with other systems. It is very advanced but easy to use once you understand how it works. The API support team is resourceful and efficient. Keep up the good work, guys!"

We have worked extremely closely with the Reckon API team for many years. They have always been quick to act not only on issues, but have been highly proactive in seeking our advice on proposed changes and improvements to their APIs, as well as assisting us grow our userbase within the Reckon community. We definitely consider ourselves a true “partner” in every sense.
