It would be cool if there is a JSON standard to publish features (and pricing) for SaaS apps - something like what AWS does for its products. Defining such a standard itself would be tricky, but it is worth trying. It might make it a bit easier to compare various project management apps, for example.
With regards to SaaS besides project management and document management what are some categories where you find picking tools the most cumbersome?
I think the greatest area that a small company could use help in is learning which tools are out there i.e. answering this very question. For instance, one firm I know had no idea how useful bill.com was and it saved them 10s of manhours per week but began using it years after it was offered.
The other area is workflow: you use software X and software Y in this way, but did you know most other companies link them up with software Z in the middle and it works much better, so long as you check the box that reminds you to tag the invoices (or whatever).
I think adding up all the time savings for certain workflows or integrations across different sets of products would be immensely useful. You're totally right there's no easy way to see that currently anywhere.
This is sort of the reason people check out state of Javascript and learn that "everyone else" is gravitating towards Vue, or that Svelte is gaining in popularity, or that VS code is everyone's preferred editor.
Want to manage a (1) 10-50 person (2) construction firm in (3) the US, should you use Basecamp, Asana or Wrike?
You have a (1) 50-100 person (2) Tech firm should you use docusign or hello for document management?
And if you already have and are committed to Quickbooks, does it change any of the answers above?
