I used the Menards Design-It Center estimator tool to generate my initial materials list. The tool has its limitations; it wouldn't go over 32' on the building width, didn't have the right door size selections, and so forth. But it provided a good starting point.
I know I want metal roofing, and a maintenance free board-and-batten look siding, but I don't have final materials selected for those applications, so I picked options that were in the right ball park, then had the estimator at Menards prepare a custom order that corrected for the estimation tool's limitations, and elided the trusses (don't want them on site until I'm ready to install them), roofing and siding.
He deleted off the sheathing, too, by mistake, and left in some finish materials that I'd probably have made a separate order for later down the line to avoid having to store them until needed.
I've ended up with some stuff I definitely don't need (three rolls of Typar house wrap, for example) and some stuff I might not use (finish moldings that may not work with the siding I end up choosing) but I have my basic lumber package!
Unfortunately we just had two days straight of steady rain, so trying to get the materials back to the slab location was carnage:
Now I have the task of re-staging everything from in front of the house :-( And of course the treated sill plates are at the bottom of the package, so I'd have been moving a lot of lumber to unbury those anyway.
The delivery driver, after bailing out of the mud pit, told me that he'd only gotten stuck one time since becoming a delivery driver. So of course he got stuck turning around to leave...

Putting the buggy back on the truck put enough weight on the rear wheels for him to get unstuck, just.
And here we are, ready to get everything stashed or staged and start framing:


One nice thing about Menards' estimator tool is how comprehensive it is. It even included sill sealer foam, nails, and clear silicon sealer for the doors and windows!
On the top of the stack in that last photo you can see the Typar, finish moldings, stair balusters (not needed) and soffit material. I need to stash that all away until later.
And on the bottom, the treated lumber I need to start...
