Magmanger and Xero work great together and the team at Magmanger cannot do enough for you, very helpful and knowledgeable and happy to support you.
I've been in publishing for 15 years and started using MagManager a year ago, wish I'd started earlier. It's a very powerful product that streamlines production, teamed with Xero it's a one-stop shop for organising and managing my business. Highly recommend.
Have used MagManager and Xero for a few years now. They integrate seemlessly, wouldn't be without either of them now - they make a perfect combination for magzine publishers.
I LOVE the MagManager and Xero combination. We use both software platforms to run 4 publications. MagManager is easy to use has a lovely interface and offers great support over the phone. We don't feel the need to use any other systems.
