I love that you can create a client and have it automatically be added to the QBO customer list. Support staff is friendly, helpful and very responsive.
Easy to use, intuitive, top notch support for the occasional issue, which has been rare. Integration with QuickBooks is pretty well seamless, makes time keeping and billing very easy.
Overall it has been pretty good, there are a lot of useful features and is mostly much faster than PCLaw.
I think the fact that I have to pay for Quickbook Online, which I repeat I hate, in order to use LeanLaw is an additional cost that I do not feel like I should have to pay.
I have problems when implementing specific time entries.
But that's as much a QB problem as LL. Not a full-blown practice manager, but I knew that going in.
