Helen,
I have an extensive accounting background and have installed high-end accounting systems. But my experience with software is not in the hospitality industry. I'm a systems analyst but my experience is not directly tied to the hosting or hospitality industry. But I have a good idea of the features that are a "must have" vs those that are nice to have but not truly required.
So, I am taking the role of being my own consultant in finding and reviewing the software available. It's a huge number of products and I have at least 25 that I am reviewing so far.
The consulting groups like Capterra offer evaluations, but they all seem to get 4+ stars with little in terms of downside. It looks like the software developers are paying to be included in the selection. It's the downside that is important. Anybody can give a rave or positive review, but software companies won't do a negative assessment on themselves.
Accountants and accounting firms have limited experience and may not be a reliable source if I don't get the negatives or the weaknesses of the software. Accountants have experience with one or two software packages at the most. So, they are generally not a good source.
It's crazy for Airbnb not to have either developed their own package or partnered with an accounting software developer to add-in the features we need. Someone must have done a careful review of at least one software package that is applicable for hosts with a candid assessment of the downside of the software.
