Start with systems thinking:

Wouldn't start a paragraph with "it." Would recommend using "it" in the 2nd sentence. "Building a payments system helps if you already have a centralized... It can be a huge initial investment..."

You don't need to capitalize Audit.

Spell out "2" in two months, "5" teams, 2 members of Lyft's Design team. An editor I once worked with told me you're supposed to spell out numbers till you get to 10.
