DCF is my go to for traditional business models that provide regular reporting of revenue. Similar to yourself I'm not amazing at it, just been shown the basics. What I really like about SaaS models is there's a quick and fairly accurate way of valuing them based on "ARR multiples", which can be adjusted for Total Addressable Market (TAM), Profitability and ARR Growth. There's also a comparative aspect to it as well, as you'll typically look at other SaaS companies to gauge a "fair multiple" in the current macro conditions. And you can look at say how a "Atlassian or Xero" compared at the equivalent point of time in their growth journey. Using this method and fundamentals, I've taken up long positions in Pushpay (PPH), Livetiles (LVT) and Catapult (CAT). I have attached the resource that was provided to me by @T.E.P.
