I did a lot of research and closely followed the development of the product before deciding to go with Krow PSA. I believe Krow to be the best Salesforce-native solution for time tracking, project management, invoicing, and resource management for SMBs. The price is a great value for all of the features that come with Krow. And the transparent pricing is icing on the cake.
The team has been great with keeping their users up-to-speed on the product roadmap and new features with monthly webinars. Krow has created a great product that feels like it has a lot of momentum behind it. And, last but not least, the product looks great! The interface is Lightning Ready -- and looks great in both Classic and Lightning Experience.
My company was able to successfully migrate from various other SaaS tools for time tracking, invoicing, and project management and consolidate them on the Salesforce platform with Krow PSA.
