Sounds good so far.

COGs should be the reverse of whatever the COGS for that invoice was.
Its irrelevant what changes have since been made. If I sell you an old
hat, and realise I should not have/didn't actually sell it after all,
its irrelevant that the new hats cost me twice as much.

Same bug here being introduced. If I sell you an old hat, and you return
it, its irrelevant that the new hats now cost me twice as much.

As I noted earlier today at Discussion Forums: Help, Assemblies

what is the scope of LedgerSMB? How far past general accounting and into
operational support of manufacturing might you want it to go? How about
defining scope and a roadmap for possible extension?
