This stuff is critical for a business. I review our dashboards daily / weekly. We use Birst now (will put you back 5+ figures) but started out with something just like this.
Glad you like it, thanks for the comment!
Ah-ha nice co-incidence - I was in your office today and telling my co-founder you are the master of SaaS metrics. :)
Looks great! You are making a big assumption with linear, fixed COGS scaling. I will probably use this, as it's a great document, but I'm going to add some more flexibility for COGS line items.
