Inline anneling and Bright anneling
(OP)
Where is the best place to do the anneling, Is it before the sizing or after?

The other comment of to decide if this is actually an anneal. I have seen much stainless tubing recently that was not solution annealed (non-uniform grain size and odd distribution of carbides) coming off of inline systems. It meets the mechanical properties so they call it good. It wouldn't pass corrosion tests.
And don't be fooled by the phrase "inline bright anneal", the inside surface is not bright annealed. The ID only sees an inert gas so there is measurable (even if invisible) oxidation on the ID that greatly reduces the corrosion resistance. This is 'wing and a prayer' tubing.

This is very common today in commodity tubing. If 304 is all that you need then it is probably fine.
If you get inline bright annealed 316 don't expect it's corrosion resistance to anything like what is in the books on corrosion. It can't come close.
