100% agree, but even if you don't go through the whole certification process (which is painful and expensive), it's worth spending the ~$1,000 on a "cert-in-a-box" kit to understand the framework of the standards and what kind of processes your company will eventually need to put in place as it grows.

Also in my experience, being able to produce existing docs around your standards and processes, versus producing them on-demand, helps inspire confidence in the prospect's due diligence team, because it shows them you've thought of this before they asked about it. :-)
