The most useful feature of this system are its reports which help us keep track of our business's performance every month/weekend etc.. Also it has integrations with other systems like Booking Engine (which I use as well) so we have all information in one place at once time. It also serves as an inventory management tool. Reporting functionality can be improved by adding more customization options or importing excel files instead of CSV formats. We needed a single source of truth where everyone could share their data easily but not sure if they were able to do that yet since i don't see any integration available between booking engine and acmosqi currently. One word - accuracy! This makes me sleep better than when using spreadsheets only. Accurate statistics about room availability make my life easier knowing how many guests will stay there next weekend and what rate.
