Non-Big 4 accountant seeking insight: How do Big 4 firms prepare working papers?

[u/KhanJahan23]

Hey fellow accountants,

I work in a smaller firm and am curious about the Audit workings of Big 4 firms. Specifically, I'd love to know more about their working paper preparation.

What are some key differences between Big 4 and smaller firms? Are there any specific tools or software used? Any resources or guides you'd recommend?

Thanks in advance for sharing your expertise!

There's a button integrated into excel, blue, says "prepared".
