Just take a few Hours, prior to beginning the rough Installations, and figure out what to do.
Get a set of "Clean" Plans - at least "D" size media (24" x 36"), and layout your Circuitry on paper first.
Count up the circuits for Panel Requirements (AKA spaces and frame types), and identify them on both the plans and the NM cable end (at the panel). This helps out logistically and makes it easier to enter circuit data in a Panel Directory.
If you can get 2 or even 3 "Clean" Plan Pages, that would be best.
Use colored PENCILS for drawing circuitry / Homeruns, where multiple "Types Of Circuitry" will be used (i.e. Lighting = Blue, Gen. Receptacles = Black, Kit. ckt = Red, etc.)
What I mean by "Clean" sheets is to find plan pages with the least amount of stuff printed on them, so the Floor Plan (Base Template) is easilly seen - plus there will not be so much confusion between what you write/draw for As-Built data, and notations text printed on the sheet.
"A" Sheets might have something rather clean (like a Foundation plan, or similar), and if there are any "P" sheets, these would be the cleanest.
One last thing, make use of Multiwire Circuits as Homeruns where ever possible.
(ohhhh, this is going to draw some flack!)
