These are separated for clarity, not because they are separate jobs. On a live account they are the same weekly loop, and most engagements start with finding out which of them is currently the constraint.
Restock planning, shipment execution, stock cover modelling and storage fee control, with bids scaled to the cover each ASIN actually has.

How engagements usually start
An account audit before anything else. I look at advertising structure, catalog health, inventory position and account health, then write up where the constraint actually sits and what the first three changes should be. If that turns out to be a listing problem rather than an advertising one, you will hear that. It is cheaper for both of us than scaling spend into a page that leaks it.
Taking on new accounts
Start with an account audit.
Send the marketplace, the category and what is currently going wrong. You get a written read on advertising structure, catalog health and the first three things worth changing, before any engagement is discussed.
